I just pulled the trigger on:
- (5) 255/70R17 General Grabber AT2's (http://amzn.com/B004QL60XA)
- (5) 17" Pro Comp 98 Steelies (http://amzn.com/B004IK9AAO)
- (5) 56029398AB Tire Sensors (http://ebay.to/1OzdA4S)
- (4) 1.75" Spidertraxx Spacers (http://bit.ly/1exoOdL)
They are going on a stock 2015 Jeep Grand Cherokee Laredo.
255/70R17 is only a little under an inch wider and bigger than the stock 245/70R17 tire size so there shouldn't be any fitment issues. Pro Comp 98 Steelies have a -6mm offset, so combined with the spacers, this set should stick past the fender a little over ~ 1.5 inches. Will post pictures as soon as they are mounted.
