My 275 on 10.5 rims fits well. My side walls are perpendicular to the road there is no stretch. I put on numerous tires a day and I put these on my self. You know when a tire is stretching to fit when you have to bead blast it to get it on. I had to actually push the sidewall down in order to get the arm of the mounting machine on. So saying a 275 has to stretch to get on a 10.5 rim is not true. I do these all day.
