How the job is done
Found it flat in Beaconsfield? Leave it where it is.
Flat tyres around Beaconsfield usually appear on cars that have been standing still. A commuter stepping down from a Chiltern service at Seer Green and Jordans returns to a sagging wheel in the small car park, or a family car on a New Town drive has sunk onto its rim overnight. It is tempting to crawl it round to a garage on the A40, but even a short distance can ruin a tyre that was repairable.
Do not move it. Give us the precise location, perhaps a numbered bay at Beaconsfield station, a house off Penn Road or a road in Jordans, and say whether the locking key is aboard. The sidewall size helps if you can read it. Once the wheel is off, the fitter sees what caused the flat and chooses between a repair within BS AU 159 limits and a replacement tyre, having quoted each on the phone.
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 Beaconsfield as well.
If the job turns out to be different, see broken tyre replacement, emergency mobile tyre fitting in Beaconsfield or puncture repair.
