At the car
Found it flat in Birmingham? Leave it where it is.
Flat tyres in Birmingham are usually discovered rather than felt. You step out to a driveway in Acocks Green and one front corner has sunk, or return from the Bullring to a car slumped in its bay. The temptation is to crawl to a petrol station or pump it up and hope, but a few hundred yards along the A41 with no air grinds the sidewall apart and makes a simple repair into a full replacement.
Leave the car, note exactly where it is, and call 07473 720871 with the size printed on the sidewall. The fitter arrives, takes the wheel off and finds the cause: a nail in the tread that BS AU 159 allows to be repaired, a leaking valve, or a casing too damaged to save. Both prices are given to you on the phone beforehand, so the decision at the car in Stechford or Yardley is simply whichever one the tyre permits.
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 Birmingham as well.
