as of right now im using 195/45 federals with a 2450lb 320whp civic lsd/traction bars/ect. and first and second gear are pretty much useless.

by the spring i should be around 500whp. what street tires do you high hp guys use? need either a 195 or 205 maybe 210 would be a stretch.

 

There's no such tire size as a "210", bud. With that much power, you're not going to have much luck with anything other than a warmed up drag slick. Depending on what chassis you have, you could probably squeeze 225's under the car, which would help things.

 

Maybe touch base with jegs.com or summit racing to see if they can help ?

 

Your going to be looking into drag radials for sure if you want any type of traction at 500whp. Also 225/50-15 is more than likely the size you'll be looking into, definitely wont be able to run slammed, but they will definitely clear.

Brand wise, I'd suggest the Mickey Thompson et streets. Great hooking tire, that still is pretty streetable

 

*215 please forgive me. im going to be using a 16x8 +20 wheel and its on a 95 ej coupe
ive heard good things about khumo xs's
