Does anyone that's lowered run a 18x9.5 +38 with a 245/40/18 tire? Considering the rota grids but currently have 245s on my car and coils getting ordered soon.

Ive run 245's on 9.5's before fine, just a bit of stretch but nothing crazy! Will definitely help when you go low!

Best pic I have for reference

How do you like the Federal 595 RS-RR? Thats the tire I just ordered for mine. Same exact size tire going on a 18x9.5 with a +38 offset
I like them. Excellent tire for the price, grip is just as good as the Hankook RS3 but more responsive to steering input. I'll be testing them at the Match Tour in San Diego next week to see how they fair against some of the fastest Auto-xers on the west coast.

Seems to be the general consensus. Let me know how they do for you at auto-x, the only knock I've read is they get slick when hot on the track. Not a big deal as I dont track the car much.

Ive been autoxing on these since November last year and they have been great so far. I won my last two races last year by a margin of 3.5 seconds instead of the normal 1/2 a second in my local STX class and took the series 4-0. One thing I will add is that they are noisy. Very noisy, like offroad mud tire noisy.

Wow ok, that may change things a bit. Maybe Firestone Indys.

If you arent racing on a regular, the 595 rs-rr could be too noisy for most people as a daily driver only tire.
