I just picked up some 33x12.50r15 procomp xterrians on 15x10 dick cepek wheels. 1 tire is fairly worn down and the other 3 have 6 to 8/32" left. Now I bought the yj with p235/75r15 on it so When I slapped the 33's on, I couldn't believe how great it looked! So now for the bugs. When I take off in 1st and accelerate I get a vibration felt throughout the jeep. Can it possibly be a mount, or u-joint? It doesn't do it anyother time but when I take off in 1st. Any ideas on whats wrong?? Enjoy the pics. Im registering it tomorrow, and still plan to make a front bumper, repaint the rear bumper, replace the front fenders, replace the front seats, do some body tub work, and anything else that my almost empty wallet will let me do to it.
