Our 2017 XC90 came with beautiful 22" wheels. Unfortunately, they are getting DESTROYED by Boston's narrow roads with granite curbs. The tire on there is a 275/35/22, which has a tiny sidewall that is part of the problem. We never had this issue with our 2011 XC90 with 255/45/20's

Has anyone fitted a 275/40/22 (1" larger diameter) or 275/45/22 (2" larger diameter) or 275/50/22 (3" larger diameter)? The taller they are, the more the side wall will bulge out and protect the rim from kissing the curbs. But it will throw off the speedometer and maybe TPMS?

If you just want more side tire bulge, go with George's answer - a slightly wider tire (e.g., 285/35r22). Minimal side effects.

If you want more tire bulge and impact protection, do both e.g., 285/40r22 (1.4" diameter increase). You may encounter rubbing issues when turning and your speedometer will be off (~3mph).

There are tire wheel calculators out there. Generally, you want the diameter of any non OEM replacement tire to be within 3% of the OEM diameter. Otherwise speed and odometer will be oof for sure, and it can have longer term suspension/ power train issues. Basically, with a 22” rim there is minimal sidewall allowance to meet the diameter specs.

You want a wider tire, not taller. More "meat" on the tire will help protect the rim edge. A meaty tire can also provide a more aggressive look.

Some manufacturers build in a rim protector, which is just a thick bit of rubber designed to protrude out over the lip of the rim where the tire meets the rim. Bridgestone Potenza RE11s come to mind as an example of one such tire.
