I have a 2005 Mustang and I got a flat on my left rear tire, so I put the donut on. I only had to drive very short distance to get the car home. My question is, do I need to switch the left rear and left front (so the donut is up front and the normal sized tire on the back)? I have about 20 miles to drive tomorrow to get to the shop to put my new wheels and tires I ordered.

I honestly dont think it will matter but if you want to be safe u can, also read on the spare it will have the speed limits for the tire and stuff like that

 

you should be fine. just drive like a super grandma

 

I'm assuming that Ford got the size right on the donut and you are running the stock tires.

If you have the stock rims and rubber on there you won't have any problems but if your tires are different than stock, I would definitely put the donut on the front. Different sized rear tires will spin at diffeent rates and fugger up your rear end.....if you have a locking rearend that is.
