I've been looking for M/T tires for my '13 GC Trailhawk in the stock size (265/60/18, approx. a 30.5" tire on an 18x8 rim) but no luck. Aftermarket wheels in an 18x8 are really limited and are too ugly imho. So I started looking at Jeep wheels and what was available on CL and Ebay. Seems that there are a fair number of people up-sizing their new Wrangler Rubi's. These come with a 17"x7.5" wheel with a M/T 255/75/17 tire (~32.1" dia.). Prices run from about $1K to $1.5K for a set of 5 new wheels and tires.
Weird... '14 Rubi wheels don't fit my '13 GC Trailhawk.
Had a chance to test fit the Rubi combo on the Trailhawk. Slipped it on the front and first thing I found was the lugs stick out further by about 1/2" because of the deep resessed hole on the Rubi rim. Plus, the lug nuts aren't open so they won't seat up against the rim. (Both wheels have the 5x5 bolt pattern, but the offset is different). The third thing I found, with the Rubi wheel pushed up against the hub was that the inside of the Rubi "spokes" touch the outside face of the caliper. Also, depending on where adhesive weights are placed looks like they could make contact with the caliper as the wheel turns.
Like the looks of the Rubi wheel just wish it fit!
Daughter's '12 GC has 17' rims, guess I could test fit those and see it they clear the caliper.
Anybody running the new Rubi wheel on a '13GC? Could it be that there's something different with the calipers on a quadra-lift vehicle?
