here is my problem, i bought new tires for my truck, and the spare is 1.2" smaller in diameter. i am trying to find a tire to put on the spare that would be the same diameter as my new tires, which are 32.8" apperantly nobody makes a tire that is 32.8" tall and fits a 17"rim. any suggestions?

 

How about going to a junk yard or somewhere you can find a steel 16" rim with the 5 on 135mm bolt pattern. This way you can run 285/75/16 tires which are the same size as what you're looking for. But I'm not familiar with anyone who makes a a 32.8 tire for a 17" rim. I know ProComp makes 33/12.50/17 tires but you might have a hard time finding a used one.
