33x12.50's will rub quite a bit. All of the 2 gen troopers that I have seen have either had rubbing or cut the fender and beat the firewall back a little bit. My 33's rubbed a lot up front on the bumper and on the firewall when turning. I cut a lot out of bumper and out of rear of fender. Don't just expect 33x12.5 to bolt up no probs. My tires also stuck out a couple inches. I had to put on a set of fender flares to cover the tires. I don't have any pics of firewall where i had to "clearance" it. IIRC, I used a 5 lb sledge.
