Hello my name is Joe and this is my first post. I would consider myself a decent mechanic like I went to school and did well and have a job but when it comes to what tires are gonna fit I am lost. I have a 2003 tj sport and I put a 2 inch pro Comp lift on and the flat tube front fenders. I was hoping to fit 33x12.50 cooper discovery SST Pro tires on 15x10 fuel revolvers. The rims have 3.75 inches of backspacing which I figured would push the tire out to prevent rubbing and I thought about getting 1.5 inch bump stop extensions to prevent it rubbing on the top of the fender when I am wheeling with the sway disconnected. If you guys think I should go smaller or you think they will fit let me know thank you!
