spare tire
 

My rear left tire just went flat. The tires I ordered won't be here for 3 or 4 days. Is it safe to drive on the spare in the meantime?

you should take one of the front tire to the rear and put the spare tire to the front. that way it won't wear out much of the LSD.

I believe the recommendation is less than fifty miles and keep the speed down.

is it less than 50mph or can only using the spare tire for 50 miles?

I would rent a car for a few days if I were you.

Why don't you just take the tire to Discount Tire and let them fix it? It won't cost you and you can drive around without the risk of problems that go with the dinky spare.

I had to use the spare the other day, and just using it to get home (1-2 miles) was no fun...i would use something else if you have the means.

Both.
