At the car
Found it flat in Tamworth? Leave it where it is.
Tamworth flats are discovered rather than felt. The SnowDome car park after a session, the long-stay at Tamworth station after a day away on the train, a Belgrave drive at seven in the morning: a nail picked up on the A5 or A51 has been leaking since yesterday and the tyre emptied overnight. Limping it round to a garage feels sensible. Rolling on an empty tyre grinds its inner liner to rubber crumbs and converts a mendable puncture into a new-tyre bill, so ring and stay where you are.
Give the bay or house number and the sidewall marking, and the fitter reaches the car with a compressor and common tyre sizes. Off the rim, the inside of the tyre tells the story, and the decision is made at the SnowDome or on the Belgrave drive: a Wilnecote screw hole within the BS AU 159 limits is patched, anything worse is replaced from the van's stock. The amount is agreed with you beforehand, never sprung on you after.
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 Tamworth as well.
