A tyre found flat outside a Cricklewood flat on a Monday morning, or in the Ventura car park after shopping, should stay exactly as it is until we look at it, not be driven round the corner.
On the London A5, cars sit for days in permit bays off Kilburn High Road and Maida Vale, and a slow leak from a gutter screw has time to empty the tyre completely. Further out, commuters return to Milton Keynes Central station car parks or Dunstable's Quadrant to find the same. It is tempting to drive a short way to a petrol station air line, but a tyre rolled flat, even slowly around Cricklewood, grinds its sidewall from the inside.
Leave the Kilburn or Dunstable car where it sits and phone with the street or car park plus the size. Diagnosis happens at the kerb. A single tread puncture can be repaired to BS AU 159, a leaking valve replaced, a bead leak on a corroded rim cleaned and resealed. If the flat has ruined the sidewall, a new tyre is fitted from the van. Verdict and price reach you before a spanner turns.
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 near the A5 as well.
Residential streets off the A5 in Kilburn, Cricklewood and Burnt Oak where the bay allows, the Broadwalk in Edgware, Milton Keynes Central car parks, Dunstable's Quadrant, Ventura retail park. Red-route kerbs are not usable. If the flat leaves you stuck in an Edgware Road lane, dial 999.

Straight after a flat on Brockley Hill or Elstree Hill North, slow down, indicate and turn into a road towards Borehamwood or Bushey Heath instead of stopping on the A5. Keep passengers away from the traffic side, find the nearest street name, and send that to us with a location pin.
While you wait
Found it flat?
A tyre on its rim outside a Colindale home or in a Milton Keynes Central car park tells a story, so read it. Screws from Edgware Road gutters can reach more than one wheel, so glance at the rest. A valve bent by a kerb, or a scrape low on the wall, points elsewhere. Do not drive it to an A5 garage; even slowly, the rim chews the sidewall. Space-savers are stopgaps for a short hop, not something for the Watling Street trunk road.

A5 FAQs
What drivers ask after leaving the A5
My car has a flat in a residents' bay in Maida Vale near the A5. Can you work there?
Usually, since the car is already legally parked. The fitter needs a moment to pull the van alongside, so tell us the street and whether it is narrow. Maida Vale sits inside the ULEZ like all of London, which does not affect the tyre work itself.
Can I drive a flat tyre from Burnt Oak to Staples Corner to save time?
Please do not. Even at walking pace along the A5 the sidewall gets crushed, turning a patchable Burnt Oak puncture into a tyre for the skip. Leave the car in the Burnt Oak side street and ring; the unit beside Staples Corner is close, and the fitter comes to you.
My tyre is flat in the Quadrant car park in Dunstable. Can you come there?
The Quadrant car park, where its owner agrees, is close to the A505 crossroads and gives the fitter a legal place to work. Describe where in the Quadrant you left the car, whether the tyre is on its rim and the size, and the fitter chooses between patching and replacing once beside it.
