the information is decent, but i'm not a fan of the doodle like images for references haha

[!Zar!]

I love how they act like they have reinvented the wheel when people have been experimenting with cambered tires for ages. Though most remove the tire once it is cambered...

[drift freaq]

I don't know,
Its a fact AAA and a lot of state rules of the road actually frown on decambered wheels in general. Why? Its considered strictly a performance enhancement to go around corners faster.

Do most states or Police make a stink? No. Can a cop pull up some odd violation on the books about it? Probably. LOL

To start selling a tire specifically setup for that regardless of the stated improvements in handling could run into a lot of nanny state regulatory situations.

I just would not put it past AAA to lobby against these as well as people like Ralph Nadar who would like to see us driving a car on guide rails that has no real power.

These are good reasons to be a supporter of SEMA. They actually lobby against this bullshit.

Though I am just stating in the current environment with our Federal gov trying to tell us what we can do, it could be ugly.

I could see it now, 17 year old kid goes out and buys Camber tires. Mom and dad ask why he can't just buy regular tires, kid explains it helps the handling of the car. Parents look at each other with scary thoughts of their kid street racing. LOL

I've seen many tires that have been shaved with camber and pretty much all performance tires are built with tread blocks and/or materials to handle camber but I've never seen a tire that had camber designed and molded into it.

I also don't see a problem selling to the public. From a performance aspect if it works people will buy it. Last time I checked you could get a number of DOT slicks at any local Discount Tire. You could also slap an off road only sticker on it and be done with it.

There are a lot of claims made by this guy but a few of them could be seen as environmentally friendly...reduced wear, quieter running....which would make me think it could also get better fuel mileage.

check these out. they are made by Optima and they have different size sidewalls on the tire. giving you better handling and braking. supposedly this is going to be a huge step forward for tires. South Coast Mitsubishi is testing some of these right now. looks really interesting.

always nice to see some new technology in the automotive world. nice post

[sw20>>s14]

wow, its like michelin pilot power 2cts with a masters degree for cars! its about damn time...

[NINJASPY]

so shaved tires for the street? what technology? Can't I just run my regular tires with camber and the tires will auto camber into "optima camber tires" ?

except when you run camber you are loosing contact with the ground... meaning you need wider tires to get same contact and your still loosing contact cus its cambered. so these tires are cambered without loosing contact area from what i understand

I guess they actually work.

I guess you should read the article. They propose that a 180 treadwear tire has better traction than a 140 which is flat out wrong.

the results are rather underwhelming. Stock Manufacturer Advans vs a performance street tire are almost the same. I'm imagining that he didn't study vehicle dynamics very well.

[VROOOM]

the stock Advans are insanely expensive and grip amazingly well. $320 a corner

looked on Tirerack. $338 a corner

I didn't say they worked well, just worked. I wonder if the treadwear rating is a result of the camber or the compound. I do not buy the increased gas mileage, I would expect it to be the other way around.

[vas570sx]

so theoretically, if the reason for running negative camber is to achieve a 100% contact patch in high speed cornering, shouldn't the camber tire put your vehicle in a sort of "positive camber scenario" during high speed cornering? and wouldn't that be a bad thing causing you to loose traction?

[kingkilburn]

I am very skeptical about this.

Each set of tires would have to be tailored to a specific car and that car's setup.

[Slammed Assassin]

must cost a lot of dough!

increased traction = increased rolling resistance = decreased mpg

Believe it or not. An Advan 430 that's on a car from the factory is not the same as an Advan 430 that they sell to tire rack. They're a different formulation and much cheaper.

Goodyear did that stuff all the time. Thats why you're factory tires may only last 20-30k and then the identical replacements will go 60k.

I'd argue that the reporter didn't know anything about cars because I don't think his butt dyno is tuned to a .02 G increase.

I see what you did there. :keke:

[5pecialist]

Wouldn't jump to conclusions just yet. None of us has experience with these.

the Evo X comes with Advan A13's.

so they make two different tires ones that come on the car and different replacement ones? that makes no sense. i doubt any tire with a 180 treadwear is gonna last 60k miles

[HyperTek]

well, how will high speed body roll in a corner affect these tires? Sounds like it makes sense when the tire is going straight that it would get full contact, but when the car enters a corner and starts to lean, it would loose contact area? THe whole idea of negative camber is for this.

[axiomatik]

except when you run camber you are loosing contact with the ground... meaning you need wider tires to get same contact and your still loosing contact cus its cambered. so these tires are cambered without loosing contact area from what i understand

No you don't. The size of the tire contact patch is a factor of vehicle weight on that tire and the tire pressure. Nothing else. Now, camber will affect the shape of the contact patch, but not the size.

after all these years and all the info out there, i still cant understand why people cant grasp or acknowledge this :rl:

[HalveBlue]

No you don't. The size of the tire contact patch is a factor of vehicle weight on that tire and the tire pressure. Nothing else. Now, camber will affect the shape of the contact patch, but not the size.

Size of the contact patch is a factor of load on that tire and tire pressure.

In a moving vehicle, especially one that's cornering at high speeds, loads are dynamic, not static, and are constantly being redistributed among the vehicle's tires, altering the shape and size of their contact patches.

FWIW, I think this concept actually has some merits.

I am doubtful of the claims of improved gas mileage. But I can imagine definite comfort and handling improvements.
