I recently purchased a new set of wheels.

18x8.5 in the front
18x9.5 in the back

I'm looking into either purchasing R888's or Federal 595's. What would you guys suggest the best tire size would be? Currently on Raceland coilovers.

What kind of power are you putting down to warrant those tires? They will wear fast and be unnecessary should go with mps4s instead.

BB3.4 I dyno'd at 548WHP.

But yeah, mps4s are a thought as well. What tire size would you recommend for the fronts and backs?

RWD.

3.4 kit, Spool FX-150 (when it was Dyno'd) now running FX-180. Spool stage 3 lpfp. And tuned by Shoup on full e85.

Full e85 and only 548 whp? That seems low I've seen people get those numbers on 93 or even 600 plus with meth and 93. But yea I don't have any experience with federals but r888r's have been used by lots of people and will hook even if you decide to turn it up.

Yeah, we were only able to hit 20PSI on the FX150. Which is why I upgraded to the 180. In the process of working with shoup to turn it up even more. Working on a lot of other things currently. But I'm sure the FX180 will put me at a lot more power.

I'm not much of a tire/wheel guy, so that's why I made this thread. Kind of wondering what size (dont really care for brand/tire at the moment) tire I should get.

18x8.5: 245/35/18?
18x9.5: 275/35/18?

Yes those would work fine until you start pushing the upper limit of around 650-700. Can maybe even get 255/35 and 285/30.
