yes i most certainly think some tires stretch better than others. i had horrible results with a 255/35 toyo proxes on a 10.5
tires i've had success stretching personally are nitto 555 extremes (whoa whatch out they are extreme
) , general exclaim, and the cheap *** chinese tires nankang...
i've done 245/35 on a 10.5 and it was stretched. presently front i have a 225x35 on a 9.5 and rear a 265/30 on a 11"
