so I just ordered a pair of Federal 595 RS-RR for the rear of my coupe, size is 275/35/18. I have a +22 offset wheel.. what are the odds of the tire not fitting? Lol I heard those tires run super wide

 

Depends on your wheel width, if they're 10" or narrower should tuck ok, if you're running a 10.5 you'll probably contact the fender edge if you run camber in-spec. Also, the 35 series will be quite a bit shorter than your OEM tire size, what tire size are you running in front?

 

 

It's going to be tight, but if you have a bit of room right now w/ the BFGs you should tuck ok, do you have a section width for the Federals vs. the section width for the BFGs? Should give you a good idea of how much wider the Feds will be. Also, when you get new fronts be sure to get 245/40s instead of 245/45s to keep diameters similar.

 

 

10.5 +22 on 275s will contact fender w/ in spec camber, but running your current -4 you should be ok (although harder on the tires at that camber). Think the best camber you could run would be something like -2.5 to clear that fender edge, and keep in mind, your tires will poke out more as you raise your vehicle.

 

The section width on the RS-RRs run super wide. My 265/40R18 RS-RRs easily ran about 20mm wider than the set of 265/40 Ventus V12 Evos, so that should give you an idea. Also, the shoulders are a bit more squared off, so you don't get any room there either.
