tire growth rate ???

is there a formula for tire growth ..... size vs. speed ??? and will a drag radial grow as much ?

Rim width vs tread width will also effect the amount of tire growth.

MT says 1.5 inch at 150 for their slick on the recommended rim, but as mentioned beadlocks, width of the rim etc. will affect it.

is that any slick size ?

I believe that was a 28x10.5s.

There are a couple of threads about this on the Bullet that I have saw....In the Drag Racing section I do believe.
It seems I remember reading that the DR will not grow like the slick.

you after the clearance or gearing change Nick?

Just come on over to the dark side.....

clearancing .... i really want to try a 29.5 x 10.5s ... i believe that will give me the additional contach patch i need ...or even try the 295 drag radial 10.9 x 30.0 but the d/r weighs a porky 38lbs per tire compared to the 27lb slick ........ so i need too make sure i got 2" inches of clearance for the slicks to work ...there is zero growth on the drag radial deals

sawzall that shit...............make it fit............it swap the gear too.

It's not that hard to clearance the fenders. You will need some little pieces of aluminum and silicone to fill the gaps you make. Takes about 2 hours for both sides. Then you can fit any of those tires. Hell, we can fit a 29.5x10.5W tire.

the car is already mini-tubbed and shortened axles , the only problem is the wheels that i ordered this last time are the wrong offset ...... so i need a new set of wheels and then a set of tires

I meant the front to rear clearancing that you have to do. You have to notch the lowers on both. For the taller tire to work.

The HOOSIER DOT Drag Radial in size 315-60R15 has 11.1" tread width, 29.7" tall and weighs 30#. Both the Hoosiers and Goodyears are considerably lighter than either the BFG's and M/T's. Unlike the BFG's and M/T's which are actually intended for street use, the Hoosiers and Goodyears warn that even though the tires are DOT rated- they are not meant to be driven on the street! If your having issues getting your slicks to hook, I doubt if it would be a good idea to try drag radials! My car is 99% a street car, so I ordered a new set of Hoosier 325x50x15 DOT drag radials for my car. From what I've heard from guys that run high powered cars in NMCA True Street, I'm confident that they will hook better than my current BFG's- BUT THEN AGAIN THAT ISN"T SAYING MUCH!!!!!!! Trim your quarter panels and run the tallest and widest slick that you can fit. But not too big, because Stephen says "BIG TIRES ARE FOR SISSIES!"
