Ive got some 275/30/20 Nitto 555s on my rear wheels and wish they were slightly more tucked- not poking a bit. I have searched in this forum and noticed everyone saying they are more square than others. How much of a difference would it make if I changed brands but had the same size tire? Also, if I have nittos in the front, what do I need to check to be sure new rear tires of different brands would work without any issues? Heard Falkens stretch better, would those be compatible with the nittos in front?
