Is there some formula that will result in the proper tire height needed for a 1/4 mile car, given a the engine's rpm and gear ratio(s)? I dont feel like spending another $350 to find out that those slicks are too short or too tall, instead of JUUUST right.

 

well pretty much anyone in here can tell you which height of tire you will want to run on a car based on what mods you have, your car's weight, what you're trapping and your ET

 

There are some calculators the might help at www.smokemup.com
