What happens
Found it flat in Stechford? Leave it where it is.
A flat in Stechford can be found by someone walking up to a parked car. A commuter returns to Stechford station and sees one corner sagging. A shopper loads bags at the retail park and notices the rim almost on the tarmac. A parent on a Glebe Farm drive spots it before school. The cause could be a screw, a split valve or a leaking bead, and driving round to the nearest garage is what wrecks a repairable tyre.
Tell us the tyre size, where the car is, and whether it has been moved since you found it. Air goes back in beside the car and the leak is traced with soapy water, then you hear what has happened: a tread puncture inside the BS AU 159 limits is patched from within, a perished valve is swapped, and a torn wall or crushed liner calls for a new tyre. Both possible figures are quoted by phone ahead of the trip to B33.
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 Stechford as well.
