Radial Slick Top End wig-wag Condition

CCRT · 05-12-2007, 08:54 PM

Looking for some help.

We run the M/T 3066R 30 x 9 radial slick on our Camaro.

Car is 3400lbs Tires set to 17.5 psi.

Right around 145 mph the body will wig wag from side to side. Can't feel anything in the steering or chassis. It's all body roll.

Back to back testing today switching to a M/T 28 X 10.5 bias ply corrected the condition.

I really hate to have to go back to the bias tire.

Does any body run these tires at 145-150 mph?

Any help or ideas would be greatly appreciated.

Thanks,

--Dave
