Ok I need some recommendation on tire sizing for my 93 Camaro. The car makes over 700 rwhp at 6200 rpm. It has a Moser 9-in with a 3.50 gear. The tranny is an M6 with the following specs.

3.36 1st gear
2.07 2nd gear
1.35 3rd gear
1.00 4th gear
0.80 5th gear
0.62 6th gear

I need to know how tall of a tire I should go with. These tires will be mounted on 15x10 Bogart RT Bolted wheels. Also what would you guys recommend for front runner (15x4 skinny)? Any recommendations on brand will also be appreciated. If it matters my car is supercharged. Thanks in advance.

 

I think 27" would work well, also less fitment issues than with a 28" I am using a 27" Hoosier QTP with the same wheels. 28" would probably also be ok. 26" would be too small.

What kind of modifications did you do to get the 27" slick to fit? Thanks

 

I'd run a 28x10.5x15 slick if you want to run any sort of decent ET.

 

Mine are pretty decent with the 27" and a 3.42 gear. No mods really needed for 27". I did trim the rear bumper cover a little to ensure clearance with tire growth.

Rich you are T400 right? He's stick, he needs all the sidewall he can get I think. Then again if his car is a tank he could probably run something okay on 27's.

If you are truley making 700 RWHP and with that steep first gear, Your gonna need the tallest tire you can stuff under that thing.

 

Thanks for the advice guys. I am thinking the car will weigh 3650 lbs with me in it. My car made 705 rwhp with the twin high flow intercoolers. Car had more in it but kept blowing off intercooler pipes. Since then I have gone with a big front mount Spearco intercooler and am running no filter on the back of the blower. I am hoping the car will pick up another 50 rwhp. I guess I will have to wait and see.
