Generally speaking I prefer smaller wheels as you get a slightly better ride and are less likely to damage a tyre or even worse a wheel by driving too close to a kerb.
Our ID.3 Tour came with 19" wheels and Bridgestone tyres (presumably self-seal.)
If I get a second set of wheels with winter tyres on could I get 18" wheels?
If I do, can I get self-seal or run-flats or are those not available for 18" wheels?
