I have a set of aftermarket rims that I'll be putting on in the spring.
Front- 17x7.5 +48mm
Rear 17x8.5 +58mm


Should I run stock tire sizes on these?
Or can I easily fit 225's in front and 255's in the rear with no clearance issues or rubbing?

I will do a couple of track days a year. Would I noticed any better performance using the 225's and 255's.

Also, ride height is stock right now but will be lowered about 1-1.5 inch in the near future.

Thanks.

 

Those offsets are pretty safe and you shouldn't have any rubbing issues if you're lowered and running 225/45 255/40. As far as getting better performance vs 215/45 245/40 I wouldn't be able to tell you.

 

I like the 225/45 and 255/40 better for your application. You can find a lot of very good handling tires in those sizes. If I can help let me know.
