Run Flat Tyres
Run Flat Features :
A reinforced sidewall which does not collapse if the tyre is punctured.
Run Flat Benefits :
If a puncture is experienced, most manufacturers permit you to drive at up to 50mph for up to 50 miles.

Run Flat Issues :
-
Handling is stiffened, with many drivers complaining of reduced grip levels.
-
A punctured run flat cannot be repaired with plugs.
-
Most manufacturers insist on replacing two tyres, so for example if you puncture your front left, you have to replace both fronts.
-
Run flats cost 30% more than regular tyres.

Summary :
-
If you have Punctureseal in regular tyres, you do not need to purchase run flats.
-
Normal tyres + Punctureseal cost less than run flats.
