Wheel Hop During Burnout After Changing Slicks

[dustin72]

I just changed my Mickey Thompson E/T Streets (31x16.50) out for some Hoosier true drag slicks (29.5x11.5W) and created a strange wheel hop problem during the burnout. Which is strange because these suspensions aren't know for wheel hop and Ive never had the issue before. As soon as I shift into second gear and start getting some wheel speed the tires start hopping violently shaking the whole truck. The crew at the starting tell me it looks like the tires are trying to grip and start grabbing causing the wheel hop. I tried many different burnout techniques still with the same result. Its very frustrating because I can't do a decent burnout now to get the tires up to temp. Anyone have this issue? This is on a 1972 c10 with a 496BBC. Runs 11.40-11.50 @120.

The ET Streets have a stiffer sidewall, that might be enough of a change to the softer sidewall if it was on the verge of wheel hop previous.

There was not a hint of wheel hop before. This particular size of Hoosiers are actually labeled as a "stiff sidewall" tire. Also, I was running quite a bit of air pressure I think (12psi) because the sidewalls weren't even wrinkling yet. I didn't want to make the problem worse.

try dropping down to 10 psi,see if that solves the problem
