will 255/65r/15 tires fit on my 1991 2door 4x4 stock blazer. anyone please help. email me at fastpace7@yahoo.com

The old rule of thumb is you can go one size bigger.
It would be better to check with some good tire shops on what will fit.
Good Luck.

not w/ stock rim get a adapter off ebay 2 in for rear and 1.5 for front and throw a 265 40 15 or a 265 45 15

Hi all,
Wanted to advise everyone that a tire size comparison sight I love is, miata tire calculator. I always use it to beef up my car tires width at least one size. With my 1990 S10, I went from 215-75/15 to 235-70's and enjoy the difference. Also, if you're looking for a nice tire edge, I went with the Firestone Destination AT.
