i havent found my answer in the search

theres a cheap pair of 265-75-15's forsale and was wondering would they fit under my truck with stock height??

 

That's basically the metric way of writing out 31x10.5x15. Under stock height they wont fit. If you're willing to crank the torsion bars you'll be a little better off but you may still have rubbing issues.

If they're cheap enough though, you could at least try and if you find they won't work, just resell them

 

they are only 60 bucks
with 90% tread but that would be 60 bucks i dont have lol, i dont know maybe ill try

 

I'd go for it. You can always spend another 10-20 bucks for a good hacksaw and make em fit.
