Any known cases of incurable body roll

[W J]

My '99 Camaro (LS1 stick) had some big time body roll/sway problems upon shut-down until I installed tubes in the M&H dot bias ply slicks. Under 15 psi created biggest problems for me....Never had a problem after the tube install....others I know w/4th gen Camaro/Firebird cars have also had the problem.....it almost always seemed to be a tire sidewall stiffness (lack of) problem, at least w/the bias plys... M/T bias ET Streets and ET Drags both acted the same way until tubes were added. I know you're talking radials, so maybe your problem doesn't relate to the one I had.....One other thing---make sure your wheels are wide enough for your tires. Good luck. WJ
