are run flat tyres good

Short answer: they're good at limp-home heroics, not at cuddly ride comfort.

Run-flats use stiff sidewalls so you can keep rolling for about 80 km at up to 80 km/h after a puncture, which is handy in city traffic or when Murphy strikes.

They typically cost 20-40% more, selection can be thin outside big cities, and many shops will bin a tyre that's been driven flat rather than repair it.

Ride and noise can be harsher, unsprung mass can creep up, and without a spare you're relying on roadside assistance like it's your new best mate.

They shine for urban commuters and cars engineered for them (with TPMS), but for country kays, long trips, or gravel detours, a conventional tyre and a proper spare still make more sense.

Verdict: good if convenience beats comfort and cost in your equation; otherwise, stick to regular rubber and keep a jack handy.
