You can actually modify the stock clamshell to allow a 245/70 tyre. I did mine about ten years ago. It involves some cutting of the plastic. And when I went to 255/70s I modded the bracket again, deleting the hinge arm completely, and just kept the rear facial plate, which was bolted to the three tyre retention bolts. Original wiring was retained. I think the thread I put up about how to do it might still be here in the archives, if you search you could maybe find it.
