I wanna run 22s 255/30/22 with a 9.5 rim NOT A RACING SET UP i know they will fit I tried them on my Last 04 gt with 265/35/22 Nexens I now have and 06 GT S/C the most I would run the set up is for 2 weeks for Mardi Gras and 2 months for the summer if that wouldn't be too much on the tranny and what about trips that wouldn't be far from New Orleans to Houston to Dallas and back I wouldn't go WOT at all at most 70-80 mph on hwy with out going into high Rpms and I would do an break upgrade before I even buy tires for the 22s
