Today a rock ripped my sidewall up on one of my 31" tires. I had to put my spare on that is a 235/75/15 which i belive is a 29" tire. is it ok to have a 31" tire and a 29" tire on the back axle or should i put the spare on the front?
Thanks

 

If your rear end is a L/S, I have been told that you could ruin it if one tire is smaller than the other.

 

when can you go get it fixed?

 

Its an open rear end and he cant get a new tire until tuesday.

 

Well since it is opened, I dont think that you will really hurt anything then. You are fine with it on the back.
