My reason for the MRAP tires is that honestly anything smaller looks comical and they are very tough with a high weight rating. Also I have a spare MRAP wheel with adapter plate and beadlock, I just have not got around to mount a tire on it, been really busy with the front suspension. I will be working on a bumper mount for the spare that will swing out to allow access to the rear of the box but also allow me to hand winch down the spare.Ok, I gotta ask.
I really think this is a super cool project, and certainly a one-off rig that is unique. However, if you ever have an issue with a tire, where are you going to get another MRAP wheel?
Why go with MRAP wheels? Other than the super cool factor, and loads of ground clearance.
If/when I wear these tires out I think it maybe easier to just buy complete tire and wheel combos and swap on my adapter plates! LOLGovernment surplus has plenty of these wheels for dirt cheap.
