At the car
Found it flat in Bedford? Leave it where it is.
A flat in Bedford is usually found, not felt. The commuter off a Thameslink train from St Pancras walks to the Ashburnham Road car park and sees one corner sagging. A Putnoe resident opens the curtains to a tyre squashed flat after an overnight leak. Rolling it as far as the next Putnoe junction crushes the sidewall and can wreck a tyre that was perfectly fixable while it sat still.
Stay off the road and call with the location, the registration and the size code. Look out the locking key if the wheels have one. On arrival the fitter raises the car, traces where the air escapes and peers inside the casing. A nail near the centre of the tread can be patched; a cut near the edge, a gashed sidewall or a crushed liner means replacement. Both Bedford prices are given on the phone, so the verdict holds no nasty shock.
On run-flat tyres? They behave differently once deflated, so check the handbook's limits and read our page on run-flat tyres; we fit replacement run-flat tyres at the car in Bedford as well.
