Why do you want a 5" lift if you don't want big tires? I've got a 3" lift and 33"s and honestly 33"s are on the verge of being too small for that imo. Look about perfect but I don't think a bigger tire would hurt except for that fact it would rub with my wheels. I think 2" more of lift and the same tires would probably not look so great.

 

I already have the 33" tires and don't have the gears for any bigger. I just want to get as much lift as possible with the tires I already have without it looking bad. And with yours being an extended cab, the tires look a lot smaller in my opinion. I think the picture olyelr posted looks great and its 33s on a 6" lift
