Run-flats and TPMS: the premium-car compliance traps
Run-flats also have stricter repair rules. Most manufacturers advise against repairing a run-flat that has been driven flat at all, because the reinforced sidewall can be damaged internally in ways no visual inspection catches. A fitter who cheerfully plugs a run-flat that limped twenty kilometres home is cutting a corner you will not see until it matters. Expect the honest answer to be replacement more often than repair, and expect run-flat sets to price at the top of the market range.
Tyre pressure monitoring is the other detail that separates careful work from quick work. Direct TPMS sensors live inside the wheel, cost real money, and are easily destroyed by careless demounting. After any tyre change the system needs sensors intact, service kits (valve cores and seals) renewed, and a relearn or reset so the car reads the correct corners. A dashboard TPMS warning that appears the day after a tyre change is not a coincidence, and a fitter who says to just ignore the light has told you everything about their standards.
