How the job is done
Found it flat in Princes Risborough? Leave it where it is.
Around HP27 a flat usually greets you on a cold morning instead of announcing itself at the wheel. A slow leak from something picked up on the B4009 Icknield Way leaves the car on its rim by morning on a drive in Askett, or a commuter returns from Marylebone to a sagging tyre at the station. Nursing it towards a garage in High Wycombe seems sensible, yet even the length of Picts Lane on no air can shred the liner, ending any hope of a patch.
Keep the car stationary. Ring or WhatsApp with where it is parked, the size code and whether a locking key lives in the glovebox. The fitter arrives, lifts the car and hunts for the culprit: a screw near the crown gets a patch-plug, while damage to the shoulder, sidewall or inner lining means a new tyre. Both outcomes and their prices are explained on the phone, so the verdict at the car brings no surprise.
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 Princes Risborough as well.
