I just got back from the dealer and verified the measurements at home. It looks like I have 32 1/4" between the axle centers. All of the other measurements looked good. I have about 3.5" from the top of the tire to the bottom of the wheel well. I have 3" from the inside of the tire to the frame. The outer tire to the trim above the wheel is close, but it might require some manageable trimming.
Me Again quoted a 33" spacing between centers for the LT235/85R16. Therefore it looks like I will need to go with the LT245/75R16. Please correct me if I am wrong.
Now I just need to find out if the tire shop is OK with putting the tire on a 6" rim! It sounds like a lot of you are not having a problem with this (Thanks JIMNLIN!).
Thanks for all of your help!
