Default Question about 28in ET drag tire growth..

I'm really thinking about switching my 4.10 gear/ 26in tire setup to a 4.56 gear/ 28x9-15 et drag setup that is really 27.3in diameter. How much do those tires grow at 125mph?? What is the "rule of thumb" on tire growth?

I want to order some gears today... but I can't make my decision until I know how much to expect the tire to grow

Thank you! What gears are you running? Are you happy with them? I'm leaning towards 4.56's with 28's... I'm planning on trapping 125 to 127mph

gomer, i have the 28/4.56 combo and the tire growth is a good 1/2-3/4 inch, when i first installed them i could put my fingers around the tires and it grew enough to hit the fender a lil so i had to trim it.

Cool man, thanks for the info. You know what I'm trying to accomplish, do you think that combo would be the way I need to go?

yea, most definaltly, the 4.56/28 combo seems to hook up alot harder and have less bog than what you have now. i love mine. and its good for up to mid 130mph range i think

It's a done deal then.. the 4.56's are going to be riding the big brown truck to my house. I'm tired of these damn 1.6x 60's.. You've got one of the hardest hooking stock cubic inch 6 speed setups I've ever seen. I know when to take advice.. thanks man.
