I have looked at many tires 21 inch rims are very difficult to find that are good. I have looked at a few and I have decided on a set because I do about 1000 miles a week for work because I own a car service but because it’s a recharge, I don’t have a spare so God forbid I blow a flat. I have been debating on getting run flats I do know they ride a little rougher, but because of what I do, it is something that I am thinking of. Does anyone have any suggestions on good run flat tires that last?? Putting price aside does anyone have the top three brands and tires for 21 inch rims? Once I get a set on if I blow a flat I do have tire coverage so it’s not really a big concern. It’s just the wear if they wear out and the first set I get because I’m getting all four at once. And I do have air suspension so my car does ride a little smoother. And of course, something that’s good with EV. A little input would be helpful because 21 inch rims are so hard to look for. Thanks so much in advance !!
