squirm is generally a function of tread pattern...

I thought it was from the sidewall deflecting, now I know better. Something like in this image(it's probably exaggerated from the camera and heat, that front outside tire is hardly holding on!):

http://www.mandhtires.com/ M&H racemasters is who molds up and constructed the tires for him. Theay are the compound engineers for the makeup of his tire. They are R-comps.


http://www.cambertire.com/technology/Default.aspx the website that explains it

click on buy now when you get there and see the tires he was on last Sunday at our local autocross event which is also the pics of his car on the top in the header of his site. He ran the 265's with the rockers also illegal due to tire width.

3° Camber Tires
3° Tires are better suited for auto cross and racing enthusiasts as well as professional racing teams. A more aggressive tread pattern, available "rockers" and wider tires appeal to the more serious of drivers. Deeper treads give customers a longer tire life compared to other available tires on the market. Variable tread depth and helical treads give a more even tire wear as the rubber wears away.

265/35R18 - R Compound* With Rockers:
Sidewall: Blackwall:
Load Index: 515kg (1135 lbs):
Speed Rating: N/A:
Tread Wear: R:
Tread Depth: 12/32" - 13.5/32":
$338.41


265/35R18 - R Compound* Without Rockers:
Sidewall: Blackwall:
Load Index: 515kg (1135 lbs):
Speed Rating: N/A:
Tread Wear: R:
Tread Depth: 12/32 - 13.5/32":
$331.28
