What happens
Found it flat in Nechells? Leave it where it is.
Nechells flats are found at the vehicle: leaving Star City after midnight, arriving at a unit off Heartlands Parkway in the morning, or stepping out on a Nechells Green street. The mistake is driving to a garage on a tyre with no air in it, even the length of the yard, because the rim crushes the sidewall on every turn and a repairable metal puncture becomes a replacement. Stay in the bay or the yard and let the fitter come.
Send the street, unit or car park entrance, the sidewall code and whether the flat wheel can be reached. The fitter comes to B7 and inflates the tyre to see where it is losing air, then takes it off the rim for a look inside. A tread puncture that meets BS AU 159 gets patched, a leaking valve gets replaced, and a tyre with sidewall damage gets swapped for one from the van. Both possible costs are given on the call, so the verdict at the vehicle 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 Nechells as well.
