I am trying to upgrade my wheel & tire package. I have 275 X 40 X 17s on my stock 98 Cobra wheels now, and I would like to go to 285 X 40 X 17s on 10.5 wide Cobra R replica wheels all the way around. The wheel mfgs. say the 10.5 wheels won't work on the front, but it looks like they will. Does anyone have any input on this? I hate to buy the wheels and be wrong. I'm told that I have to use 275 X 40 X 17s on 9" wheels in front & 285 X 40 X 17s on 10.5 wheels in the rear. 315 X 35 X 17s are shorter than 285 X 40 X 17s, or I would use them on the rear. 315s on 10.5s on both ends would be the best, but I'm told that won't work either. Any input would be great.
