Default 18x9.5 Rota Grid on a wrx?

hey guys, just looking for some advise on tire size for 18x9.5 Rota Grids. i do not have coilovers so i am aware that i cant run as wide of a tire. i am also aware i need rear camber bolts / rolled fenders. i would like to know if anyone out there is running a setup like this on springs and if so what tire size worked for you?

thanks guys!

Smallest tire you can get away with is 245/35/18...

It's about offset and tire width more than rim width. 8.5" is a nice cutoff because there are lots of +48 and higher options out there. That gives you more flexibility on tire width and fender clearance.

I run 17x8.5" +48 with 255/40/17 and I do have slight rubbing in the rear but nothing a small rear fender roll wouldn't fix.

You can get rotas in 18x8.5" +48 and run 255/35/18 if you want. Will likely require a small roll in the rear (matters on your suspension) but not much more. 245/35/18 should work even easier in that size though.

Those aren't as "hellaflush" as 18x9.5" +38 grids though. Course, that's a good thing if your goal is more tire width, keeping your suspension working properly, or fewer fitment headaches.

ya im thinking of just playing it safe and going with the 18x8.5 Rota Grid - Hyper Black. they have a 44 offset. i have Rota G-Forces 17x8..48 offset..so i hope they will fit with no extra work...what tires size you think would be best for the 18x8.5? thank you again for your help mosc
