does everyone have the same size tire as a spare that u drive on? or does everyone just hope they never get a flat? im thinking about going to 285/75/16 and im slightly worried about that darn spare, if i ever got a flat! so should i worry about it or not?

 

As long as you have an open diff in the rear you should be ok to run different size tires for short distances. If you have a posi and a flat in the rear you would need to do a swap with the front axel(big pain but would work in a pinch) I would reccomend getting a 285 spare.

When I put my 285/75/16's on my truck, I had the same concern. I found a good used 285/75/16 and use that for my spare. It fits fine under the truck even with the mag hytec diff cover.

thanks for input, ill probably get a used spare in the same size.
