Okay so im finally building my OBS gmc, im ordering 20x12's but i already have 1 brand new 265/50r20 nitto terra grappler to save a little money i want to try to run that on these wheels. Iv called around in my area and no one really wants to touch it but iv heared of it being done. Does anyone know 100% that a 10.43 width tire will stretch on a 12 wide rim?? Or have pictures of this stretch??

Thanks for yalls time.

That is going to be huge stretch on x12, even 305s have an 1/2" of stretch to fit x12.

Way too much stretch for that little sidewall. I stretched a 245/75/16 onto a x12 and it was a lot even with the flex of the large sidewall and it still looked terrible. No way would I recommend running that. Like everyone else said, save yourself the headache and how shitty that will look and get 305's
