Default Re: Will my spare tire still be useful?

I can see that there are some interesting differences of opinion! Buying the same tire (and therefore wheel) for the spare is not such an easy option because of:

a) The extra cost
b) Possible changes in the mounting of the spare on the back of the car.

In my case I cannot mount my 37x13.5 R20 Nitto Mud Grappler on the frame at the back of the car without making some alterations. These alterations would then make it impossible to mount my current spare, which is the same as my every-day tires (LT325/60 R20 Nitto Terra Grappler).

Pardon my rookie ignorance, but is is not the case that, unless the difference in rotational speed causes the TC to think there is slip (and therefore applies brakes to the smaller wheel), the diff should compensate? Of course I will not be able to lock the center diff, or the rear diff....
