I have a 2010 G37S sedan. I only have 4000 miles, but I wanted to know if anyone has upsized the rear tire to a 255/40/18 instead of the 245/45/18. It should fit on the stock sport rim and it's close to the same diameter. Thanks!

Since it's under 3% difference in diameter it shouldn't effect your VDC and ABS systems, you'll have about a 1.5 mph slower reading @ 60mph though (you'll really be going 61.5mph) No problem w/ the tire fit on the 8.5" rear rim. May have to reset the tpms sensors since it's a new tire size but not sure.

There is no way to reset the TPS sensors for a different size tire.
