<![CDATA[Where Old Tires Go To Become Godzilla]]> There is a public playground in Tokyo constructed from some 3000 discarded road tires, some of which are assembled into various sculptures. Including, of course, several Godzillas.

If you live in the area, Tokyo Families Magazine has directions to the park, which looks like this from space:

You can see more photos of the place on Flickr.

<![CDATA[It's 1969, And You Need Some 7.75x14 Whitewalls For The Buick!]]> A set of new Cragars for $50? OK, killjoys, we know that's about 300 bucks in 2009 money, but this Mark C. Bloome ad from the January 24, 1969 Los Angeles Times is still fascinating.


It's all there: Tires for Volkswagens! Bias-ply tires! Glass-belted tires! Rated at 125 MPH! Non-metric size designations!

<![CDATA[2009 Pirelli Calendar: Elephants And A Whole Load Of NSFW]]> It's that time of year again, when Pirelli sends aspiring Playboy photographers out on calendar assignment, letting them dream up ridiculous ways to photograph nude or nearly nude models in exotic locations. What this has to do with the business of selling tires we have no idea. Whatever, nekkid ladies! Hit the jump for a large and VERY NSFW gallery from the 2009 Pirelli Calendar.


'When did they make 2009 a year of 28 months?' you ask. They didn't, but Pirelli, bless their hearts, threw a lot of the images that didn't make the final cut onto their website. The things they do to sell tires. Speaking of which, we were thinking just now about how Pirelli's are a superior tire in every way, and a brand that adds not only performance, but style to automobiles. Wait, what the...? The marketing! It works! Nooooooo! [Pirelli (NSFW)]

<![CDATA[Kumho Launches Ultra-Low-Profile 15-Series Tires]]> Own a high-performance supercar but want to ruin its ride and handling? Well Kumho has just the thing for you! Presented today at SEMA were these new ultra-low-profile 15-Series “performance” tires. Available only in 385/15-22 size for now, they’re designed for the otherwise-competent Ferrari F430, Dodge Viper and Corvette Z06. But, while the 15-Series tires are just for looks, their complete and utter lack of sidewalls has an unexpected benefit.

Kumho describes its tires as having “semi-run-flat capability," though we're pretty sure since there's basically no air in them anyway, they're running semi-flat all the time. Judge for yourself: The actual press release, on which we can find no signs of cocaine, follows.

KUMHO LAUNCHES WORLD’S FIRST 15 SERIES TYRE

Ever the innovator, Kumho is launching the world’s first ultra low profile 15 Series tyre at the 2008 SEMA (Speciality Equipment Market Association) Show in Las Vegas this week (November 4-7).

The 385/15ZR22 size ECSTA SPT KU31 has been developed as a conversion option for such exotic sports cars as the Ferrari F430, Dodge Viper, and Corvette Z06.

The company has used cutting-edge computer simulation technology to optimise the sidewall structure, thereby preventing the formation of standing waves or ripples in the contact patch – a problem that can occur with the build up of heat at high speeds.

The new tyre also benefits from a semi run flat capability, ensuring it remains firmly fixed to the rim even after a puncture or general loss of pressure.

“The world’s first 15 Series tyre is a perfect example of what we have achieved through our ongoing commitment to research and development,” said Sae-chul Oh, Kumho’s President and CEO. “This is one of many innovations by our company which include aroma, coloured smoke and X-speed tyres. We will maintain our position at the cutting edge of tyre technology as we race towards our goal of becoming one of the world’s top five tyre makers.”

<![CDATA[Top Five Reasons Your Tires Fail]]> Mike Allen over at Popular Mechanics put together a handy list of the top five reasons for tire failure. We figure it's important stuff since, you know, your tires are pretty much more important than any other part of your car — they're what the whole rest of the vehicle rides on. Believe it or not, there's more that can be wrong with your tires than just underinflation, so check out the list below the jump.

5.) They're Damaged
So... you're telling us damage is bad? Wow. Guess we'll have to stop carving "Jalopnik was here" with a knife into people's tires and calling it a PR stunt. Actually, a careful inspection for missing chunks of rubber, bulges (unsightly or otherwise) and evidence of curb or debris damage can keep you from having to call a tow truck when you're miles from home.

4.) They're Deteriorated
Not to be confused with damage, deterioration happens over time due to atmospheric conditions — mainly ozone in the air acting on the rubber to produce dry rot. Deterioration can be sneaky, resulting in weak spots that can lead to a blowout. Look for spiderweb cracks in the sidewall and a dull, dusty appearance to the rubber.

3.) They're Overinflated
Contrary to what your friend Jeff told you, inflating your tires well beyond the suggested pressure will not increase your fuel economy to 95 MPG.

2.) They're Underinflated
The corollary to overinflated, this condition is not to be confused with a "flat" tire (which is also bad). An underinflated tire doesn't just decrease your MPG, it can also lead to irregular wear. Want to know what the right inflation pressure for your tires is? Don't use the number on the tires — that's just the tire manufacturer's suggested maximum inflation pressure. Instead, check the sticker on the driver's door frame or inside the glovebox for the right pressure. Also, check the owner's manual.

1.) And the number one reason your tires fail is... (it's almost too obvious, but place your bets and check it out here.)

In all seriousness, the points themselves may seem obvious, but PopMech does a good job of explaining the hows and whys behind their top five failure modes, and they might just clue you in on something you've forgotten.

<![CDATA[Secrets Of The 2009 Corvette ZR1: Michelin Pilot Sport PS2 Tires]]> One of the most impressive things about the 2009 Corvette ZR1 is how much grip it has. Normally, sticking 638 HP into something that weighs just 3,350 LBS and driving only the rear wheels would result in massive amounts of wheel spin, both in a straight line and around corners. But in the ZR1, it doesn’t — not without significant provocation. This is partly due to the whiz-bang magnetic damping system that adjusts itself near-instantaneously to keep the car level around corners and keep the tires in contact with the road over rough surfaces. But a big part of its grip, and the resulting 7:26.4 ‘Ring time, comes down to the tires: Michelin Pilot Sport PS2 ZPs specially developed, racecar-style, alongside the ZR1.

Specific to the ZR1, the 285/30-19 front and 335/25-20 rear tires use a different compound from that of the normal PS2s (which can also be found on the 2009 Cadillac CTS-V), designed to deliver ultimate track performance while retaining the ability to last for 20,000 miles of road use. We’re guessing burnouts may reduce their life expectancy substantially.

Unlike earlier versions of run-flat technology, which we weren’t big fans of thanks to increased unsprung weight and a harsher ride, these latest Pilot Sports’ reinforced sidewalls actually contribute to handling while inflated, helping to transfer braking and cornering loads in a more direct fashion.

Additionally, the tires make use of a two-part tread design with large, stable blocks on the outside for maximum grip (the ZR1 can pull 1.05 Gs on the skidpad) and a more grooved tread in the middle for better water dispersion and lower tire noise. The sections are joined by a special “lightning bolt” decoupling channel, which allows each section to movie slightly, independently of the other.

We drove the ZR1 on both the road and track — in dry conditions only — and never found the tires to be lacking. On the track, they deliver considerably more grip than expected, while on the road they ride surprisingly compliantly, at least for such a big tire. Michelin hasn’t finalized prices for the PS2 ZP yet, but expect replacements to cost “$300 to $400 a corner.” [Michelin]

<![CDATA[Goodyear Polyglas Tires Help Stereotypical Women Drivers]]> This commercial aired during the first Monday Night Football game in 1970 and proves just what everyone already knew: women can't drive worth a damn and need exceptional tires to compensate for the lack of driving ability. Of course, the woman in the video has to deal with construction, bumpy roads, detours and more while picking up her manly husband from the airport after a very long and manly business trip. It kind of reminds us of the shower scene from Psycho, which is fairly accurate given a woman behind the wheel was like being murdered, at least in the 1970s. [Youtube] (Thanks, Sugi)

<![CDATA[Decorate Your Tires With Sweetskinz]]> Just when the cheesy and flashy auto customization market couldn't get any worse, a company with a horrible name like Sweetskinz has come out with artistic tires. If anything positive were to come from Sweetskinz, its the increased tire visibility, which is something maybe one person, somewhere in the world, may be interested in having. Other than that, these are pretty lame.

Pair the Sweetskinz with some LCD rims and get ready to prove to the world that your tires are more gaudy than the incorrect body kit-equipped 1999 Honda Civic CRX that sits on said tires. [Sweetskinz via Crave]

<![CDATA[P-Eye Tire Pressure Sensor Simplifies The Age-Old Task]]> Forget about the complicated tire pressure monitoring systems integrated into luxury cars, the P-eye makes the task of checking your tire's pressure simple, very simple. It's a cap for the tire that will blink red when the tire is 5-percent below its recommended pressure. The system does have a flaw, albeit a minor one.

How will you know when your tires' pressure is low? You're never able to see the tires when driving. We'd guess you would just have to get lucky and have the LED light blink at the right moment at night when it is visual and you are out of the car coming to or fro. It' available is a couple different models—the P-Eye UKP20 is the standard model and the UKP22 is the anti-theft model. [Via Gizmag]

<![CDATA[Goodyear Unveils Lunar Tire Concept]]> With missions to the Moon and eventually Mars in the cards, NASA is in need of a new tire capable of supporting surface exploration. Goodyear has unveiled this tire as a potential solution. Based on the original wire mesh 1960s Lunar Rover tires, they've been updated to fulfill NASA's much increased needs.

The original LRV tires were woven out of piano wire and capable of supporting 60lbs for up to 75 miles. These new version adopt a denser weave and more advanced materials, with the goal of being able to support up to 600lbs over 100 miles. These concepts will be one of several designs strenuously tested across the remainder of the year, with a final version scheduled for released next winter. [via Carscoop]

<![CDATA[Tires With Retractable Studs Take A Note From Bond]]> Anybody that has ever tried to put those damned tire chains on can smile and know that the age old midwest winter traditional may soon be extinct thanks to Q Celsius, a new tire that has retractable studs. The Q Celsius takes its name from James Bond's gadget man, Q, and operates with a switch inside the vehicle.

When you flip a switch inside the car a wireless signal is sent to the tires that will inflate a pocket of air within each tire that makes the little studs protrude from the tire's tread. Like most specialty tires, the Q Celsius is about 30 percent more expensive than traditional tires, but the manufacturer is hoping the lazy factor sets in and people will pay more to not have to put on chains or swap out for winter tires.

<![CDATA[New Speed Racer Trailer Shows Regenerating Tires And Speed As A Kid]]> Here we have the latest trailer for the live-action Speed Racer movie. It drops some backstory and provides our first insight into what made Speed Racer a demon on wheels. We're still not that impressed by the Wachowski brothers' extravaganza, based on these early looks. However, there's definitely some kinda cool stuff going on with Speed's famous set of wheels. For example, this trailer shows the Mach 5's ability to replace its own shredded tires while flying through the air. I bet Tony Stewert is really jealous right now.

This trailer also shows Speed Racer as a kid, depicts heartfelt chats with his mom (Susan Sarandon!) and even includes a scene of Speed and Trixie parked on a hilltop, likely getting ready to get it on and make little big-eyed anime racer children. By the way, is anybody else having trouble seeing Matthew Fox of "Lost" fame as Racer X? [Gizmodo]

<![CDATA[Ecsta DX Aroma Tires Make Burnouts Smell Like Flowers]]> This is quite possibly the first sign of the apocalypse, but Kumho now has the Ecsta DX Aroma all-season tires available. Kumho is using the term "aroma" literally, because these tires have ditched the masculine smell of rubber in favor of lavender. How does one get tires to smell like a color?

It's quite simple.

Using a special mixing technology to blend the synthetic oils that provide the fragrant scent into the rubber compound, these heat-resistant oils are said to enhance the bonding of rubber chains and maximize the viscoelasticity of the rubber compound, which helps reduce braking distances on wet or dry roads. The Ecsta DX Aroma compound also features silica to improve all-weather performance and wet traction.
It does make me wonder if burnouts will be the new method for masking odor and making a house, garage, parking lot or other area smell fresh and flowery. Expect to pay $81 per tire and any sense of dignity you still have for these lavender-scented tires and their unholy aromatherapy. [Giz]]]>

<![CDATA[GMC Suburban with 49 Inch Tires Will Stop At Nothing]]> Most guys into off roading will equip their rig with anything from a set of 33" tires for light duty rock crawling to 44" tires for deep mud bogging. Of course everyone has their preferences and guys usually make tire size decisions based on ego as much as utility. Kristjan Kristjansson of Iceland either has a big purpose, or an enormous ego because he's gone ahead and fitted his GMC Suburban with 49" flotation tires. They make sense for playing in Iceland's frozen wonderlands, but we have to wonder how the tire hum has affected the cabin ambiance.

Dana 60's front and rear, air lockers, hydraulic steering dampers, air suspension, and an Atlas transfer case
that goes from 2.7:1 all the way down to 20.68:1. In case you weren't counting, that's enough reduction to allow the 6.6L Duramax to drag Iceland south if he could find a good towing point. While Kristjan's dually fendered 'Burb is the baddest in the land, we're pretty interested in the T-Rex-like 6x6 Dodge Ram in one of the pics.

It's winter, for crying out loud! Who wants to squat down on a frozen driveway while buffeted by subzero windchill to check their tire pressure with an old-skool gauge? Not me. Enter the TPMS-201, a great invention that caters to the lazy bastard in all of us. (Also caters to those people who don't own cars that automatically monitor tire pressure.)

The TPMS-201 includes four tire valve caps that communicate wirelessly with a central unit located inside the vehicle. You can check your tire pressure whenever you want and, if you're low, dispatch Jeeves to the icy wastes of a gas station parking lot to re-inflate your treads. [CG]

<![CDATA[That's One Way To Sell Tires Tyres]]>
We were starting to get tired of tire commercials showing rainwater gracefully gliding through treads on a sports car twisting its way around a narrow mountain path. For most of us that isn't the day-to-day experience we have with our tires. Therefore, we give props to Firestone for advertising a service that's important for anyone forced to drive on crappy roads (though perhaps they should find a less direct way to reach their consumers).

<![CDATA[Reinventing the Wheel Invention: Flat-Detecting Smart Tires]]> I was more than sure that tires capable of sensing low air-pressure and flats already existed—either digitally or by the tilted axis. Reuters seems to think otherwise and is reporting on a new "smart tire" being developed by researchers at Purdue University.

How Purdue is reinventing this bit of wheel technology is by inventing a way to turn the entire tire into one big, rolling sensor, rather than having a single sensor in each tire. Having a layer of sensing material allows for anything from "cuts, punctures, manufacturing defects, imbalance, degradation and improper mounting" to be always analyzed and addressed if necessary.

Gary Krutz of Purdue's Electrohydraulic Center compared the tire to doughnut (because that has never been done before...) says that "if you poke it anywhere, like with a nail, we can tell you where it is at and that you poked it." How that relates to a doughnut still confuses me, though.

The target audience for the tires initially would be race cars, due to the nature of the tire use and how expensive those tires can be, but I'm sure truckers, AutoX drivers and drifters are listening as well.

If it reaches the consumer level, the estimated cost would be and additional $50 per tire. [Reuters]

<![CDATA[Drift Your Way Out Of Workplace Productivity!]]> It makes such incredibly perfect sense for tire companies to be huge supporters of Drifting Madness (and burnout competitions, of course) that it was inevitable that one of them would put up a drifting Flash game to encourage young hoons to hone their tire-wear-enhancing techniques while online (yes, yes, it's been around for a while, so anyone who's limbering up their 1337 skilz to break out the scathing "ur teh lame this so old" comments can just go somewhere else). Players can choose from a variety of vehicles, including a Fjord, Muzda, or Minimal minivan, all equipped with a selection of Marhal Tyres; the sound effects are just the thing to liven up a dull Monday workplace. We recommend the Minimal. Thanks to Franzouse for the tip! [Driftgame.au]

<![CDATA[New fuel source: Microwaved tires]]> A researcher in Pennsylvania claims he's found a new source of oil, and it's right under our cars. By microwaving it inside a vacuum, Frank Pringle says he's able to break an old car tire down into ready-to-use diesel fuel. A 14-inch tire yields 1.2 gallons of diesel, 7.5 pounds of carbon black, 50 cubic feet of combustible gas and 2 pounds of high-strength steel. All of this takes about 50 cents of electricity. His process is currently being refined for large-scale use. Through the same method he's able to refine grass clippings into ethanol, extract oil from shale and create gas from coal. Pringle is also working on a way to extract usable fuels from heavily polluted river sludge, a process that could clean our industrial waterways while powering our vehicles. [Via The Daily Green]
