Written by someone with a loose grasp of automobiles (or at least tire treadwear ratings), but an interesting article and concept.

Personally I'd go for some camber tires - its not like I'm rotating them now.

I find it difficult to believe how this guy was able to get a patent on cambered tires in 1999. There are lots of prior art examples out there.

Tire makers like Hoosier and BF Goodrich were making cambered tires for autocross in the 1980s and NASCAR started using them in the early 1990s.

I am quite skeptical of this. I have MUCH More to add but I am on my phone typing this and I will have to wait until I get to a computer to elaborate. In a nutshell, static camber means dick compared to dynamic camber which is much more complex than adding tires with 2 degrees of negative camber built in.

So looking at the test results, the stock tires launched better and produced higher steady state cornering than the 140 TW rated camber tires. Looks to me like these things don't work. I wonder why they left out standard r-compond tires to compare..

I liked the statement that the R-compounds gave 4% better cornering increase and 6% reduction in braking distance compared to the Advans, as if they would otherwise be (without their "cambered" profile) roughly equal to the stock Advans on the Evo.

Sorry, someone doesn't know their topic very well.

So the negative camber that's dialed into just about every car to improve it's lateral grip....this tire tries to get rid of it.

No, the tire is designed to lean, so if you have 2° camber, instead of the outside of the tire being off the ground normally, the tire will have a full contact patch. When you corner and the car rolls over, the tires are supposed to have a full contact patch the whole time while a traditional tire with camber would increase contact patch as the car rolls over.

I don't really get the point of this... the reason for camber is during aggressive cornering or acceleration to give more contact. How would this help?

JonBoy

Because a tire with negative camber doesn't have 100% contact. The outer portion of the tire is off the ground in some form or fashion. With this tire, the negative camber is built into the tire so you get 100% contact at all times (theoretically, at least).
