At the car
Found it flat in Sparkbrook? Leave it where it is.
A tyre that has gone flat overnight on Henley Street may have a nail, a leaking valve, a corroded rim seal or a sidewall cut, and you cannot tell which from the pavement. Driving it even the length of Walford Road grinds the sidewall between the rim and the road and turns a patchable hole into the cost of a new tyre. Restaurant staff finding a flat van in a Ladypool Road yard before opening have the same choice: move it and risk the tyre, or leave it and call.
Ring with the sidewall size and the street, or send both by WhatsApp with a photo. At the car the fitter inflates the tyre and finds the leak, then decides: a central hole under 6 mm is repaired to BS AU 159, a valve is replaced, a sidewall problem means a new tyre from the van. You hear the verdict and the price before any work starts. Have the locking nut key ready, and say if the car is in a yard rather than on the road.
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 Sparkbrook as well.
