I am putting a set of ss 10 spoke rims with 2 inch adapters for the front and 4th gen rear for the back on my car. Anyway, I was wondering what is the max tire that will fit this size without fender or wheel well modification. I am thinking of going with a 265- 40 r17 or a 275 40 r17 all the way around. Any suggestions?

 

275/40/17's will fit fine all the way around as long as you get the right thickness of spacers.

 

yeah, but will 2" adapters with this wheel be enough?

 

I dunno. You'll have to figure it up. This page might help.

two and 1/4 should do it.
