So here's the situation. I picked up a nail in one of my (aftermarket) tires and it isn't repairable. I can't get a new Tire until Tuesday. For now I put one of the factory wheels on so the car can be moved if necessary.

My question is if the car is able to be driven without ruining the trans or SH-AWD, or is it useless until I get the tire replaced?

 

1% will not make a difference. The spare tire is more than 1% smaller than the stock tires.
