Nitto 555r

+1 on the 275. just went to a tire shop couple days ago to get the widest on the back with quads. looked it up and then came and took a look at the quads. told me 275/40/17, and that might be pushing my luck. couple days before they're on though... thats with quads flipped too. bought new quads too, so i hope they're arent any bigger than the stockers!
 
I heard of someone doing it on here...I think it was in a thread by Strype.

I know a 275 nitto only runs a bit bigger than a 255 from another brandm, so I wondered if a 315 might be closer to a regular 275.
