Tire growth

GTX JOHN · 10-02-2022, 01:59 AM

My Caltracs lift the rear end very little if at all.
With a Radial you would be probably OK. but
as i recall the DO tires is a bias and I think
you will have an issue!

On a launch the tire will bunch up in the front.

Thanks guys! I think I’m safe on the launch, I checked a bunch of mustang photos by 4284spd and all the Cal-Trac cars separate on the launch. Richie Paulies C/SA looks like it is at least 3” or more. (It may be a result of the mustang rear end mounting. They look a lot like my ladder bar car did)
So now my concern is growth at the top end, I guess I’ll try some test runs when the car is finished and sneak up on the mph keeping an eye out for rubbing. I may have to order some new radials.

Not sure if this helps, but i called hoosier on the 18200 that i'll be running and they told me 1"-1.5" max of growth at roughly 130

On my car at 120 mph, growth seems like 1+ inch in radius.

Thanks for the added info, sounds close but might make it.
