How the job is done
Found it flat in Potters Bar? Leave it where it is.
A flat tyre in Potters Bar often appears quietly. A car left all day in the railway car park by a King's Cross commuter settles onto its rim, a slow leak empties a tyre overnight on an Oakmere driveway, or a family returns from Furzefield Leisure Centre to a car sitting low. Driving it any distance, even to the petrol station on the A1000, grinds the sidewall and can turn a repairable puncture into a scrap tyre.
Stay put and ring with the location, the registration and whether a nail head shows. The car is raised on the jack, the tyre removed, and its inner wall inspected for crushing or rubbing. A tidy tread hole that satisfies BS AU 159 gets repaired there; any sidewall damage means a replacement of the same size. You hear the cost of both before a tool touches the wheel.
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 Potters Bar as well.
