Alright, here’s an example of 235/75/15 on a 15x6 rim. On any decent cornering, courtesy of the weight (4550) of this Riv, the sidewall wears and touches the pavement. Even at 40 psi A good example is the right rear tire at 40 psi The sidewall is on the ground in the first pic, loaded up with 700 pounds of cousins, so about 5100 lbs. The second pic is it sitting normally with no people inside I want to jump up to 275/60/15, when I can get the whole tire tread on contact with the ground all the time, even at higher psi like 35 Would the added weight of the Riv prevent the whole car from riding on the middle contact patch of the tread, or am I dreaming?
I think a 6" rim is too narrow for a wider tire and a Riviera is too big a car for a 6" rim. You might try one size larger 70 series if available but I'd think the 275/60-15 would never hold 35psi and run with a full contact patch.
Bingo, congratulations and your win is a glass of good german beer to be picked up in person in Schweinfurt, Germany. And here is the answer for all others who tried so hard: Left is still 245 Someday, sir.
As I converted from 8.2 to 8.5 I decided to leave the springs out and to put the axle in complete compressed position to see if something could rub. I also did the "one side completely compressed, and the other side in complete rebound" The tires newer touched anything with some safety margin left. I took some pictures with the axle in complete compression. Lower shock mount and exhaust no issue at all.
