Hi, is it possible to change the tyre profile from 45 to 50 or 55 in VW Tayron R line without changing the alloy size?
Moving from a 255/45 R19 to 255/50 R19 tyres will make the sidewall substantially thicker, approximately 11%, which is likely to have a positive impact on bump absorption. At the same time, the overall height of the tyre as well as its rolling circumference will increase by 3.5%, which increases the ground clearance by a small amount. So while it is a safe upgrade, do make these checks before finalising: tyres rubbing against the wheel well when steering from lock-to-lock or going over bumps with passengers.
255/55 R19 will not be a correct upgrade.

Please don't upgrade to 255/50 R19 tyres. I burnt my fingers doing so. Inner surfaces of the tyres rub against the shock absorbers and tyres get damaged
