Sorry i took so long to get back to u.......didn't see the message lol. My tires are 285/75/17's and i put them on Mickey Thompson classic II rims that have 4.5" of back spacing. They set the tires out about a 1.25 farther then stock (if memory is right) which stops tires hitting on the inside when u turn. They would still hit at complete full turn on the plastic air damn but not bad and didn't hurt anything and only if u held it at full turn. Drove with this set up for about 2 month and did the Lingham lake run and the Liingham towerline out to 41 hwy along with road allowances every weekend. It would rub on the Sahara fenders when it flexed and had to keep the wheels straight when flexing but i never hurt anything, drove great on the road. Installed a daystar 1.75 lift and put JKS quicker disc on and now i haven't had any problems. Seems to work good disconnected and hasn't hit anything even at full flex. Hope this helps!!
