Hello all, I just had my rear tires changed on 02 HR DP. I had Goodyear 22.5s and went to sumatomo22.5 now left side tires are close to wheel well while right side is a couple of inches away. Any thoughts?
That doesn't explain why one side is different than the other. I think he is blowing smoke at you.
Are the Sumitomo's the identical size - section width as well as diameter? If so, there should be no more than a fraction of an inch difference in actual width. and both sides would be the same. What is the full size designation, e.g. 295/70R22.5?
Just relating my experience with new tires. I had Goodyear G670, same size 275/70R22.5 that were 8 yrs old. Bought new Sailun S637 tires in 2017-same size. The Sailun tire tread is approx. 1" wider than the old worn-down Goodyears were, but the width of the bulge in the tires are the same only the Sailun sidewall and tread are more straight up and down than the Goodyears.
Grab your tape measure and begin the comparison.
Sumitomo lists the "section width" of that tire as 0.5" wider than the Goodyear G670 of the identical size. 10.9" for the Sumitomo, 10.4 for the GY. The GY spec is for mounting on a skinny 7.5" wheel, though, while the Sumi specs is based on an 8.25" wheel. That can make a few tenths difference.
Regardless, both sides ought to be identical. Something is fishy!
