Thanks so much for the feedback. I’m going with 215/45 R 17 size and that should work fine. I will transition to conventional tires instead of run-flats since my research indicated a number of issues with run-flats. I have found the run-flats wear quickly, and both times I got a flat the tires could not be repaired and had to be replaced. If I was in a rural area, finding run-flats in stock at a repair shop could be a challenge.
I’ll report back after trying the conventional tires.
