I've got 9.5" in front and 10.5" in the rear. Im going to be running PS2 on the wheels. What tire size in the rear will match closest to a 255 in the front? (Proportions to bulge or stretch from the lip)

Thanks

 

285 seems to be the optimal width to go with the 255s.

 

Thanks Dave. Now to bend over while I pony up for the michelins.

 

They're worth every cent. That's what I'm running on the same size wheels as what you asked about.
