A run-flat is not an ordinary tyre with a different badge on it. The sidewall is reinforced so it can carry the car for a limited distance with no air in it at all, and that stiffness is part of how the car rides and steers. Manufacturers that fit them set the suspension up around them, and a great many of those cars have no spare wheel anywhere on board, because the tyre was meant to be the spare.
Which is why the replacement has to be like for like. Putting a conventional tyre on one corner of a car built around run-flats changes the balance of that axle and leaves you with no get-you-home capability on that wheel, in a car with nothing in the boot to fall back on. We read the sidewall, confirm what is on the other three and fit the correct type, balanced and torqued at the car.
6mm across the central three-quarters is illegal, and the penalty is per tyre. Where a tyre is genuinely past it, we bring the correct size out to the car in Belgravia and fit it where it stands, balanced, valve checked, pressures set. A Belgravia cul-de-sac or a Westminster main road, tell us which. A tight terrace in Grosvenor Gardens or a narrow bay on Vauxhall Bridge Road is usually workable. A SW1 address in Buckingham Palace Road and one in the Ebury Street area are the same round.

Victoria is not a place you can leave a car sitting for two days waiting on a tyre, between the restrictions and the cost of whatever bay it is occupying. That is the practical argument for fitting the right thing today rather than the available thing today. Correct type, correct size, balanced beside the car, and you are back in the traffic on Vauxhall Bridge Road the same afternoon.
A driver near Grosvenor Gardens discovered their car had never been supplied with a spare wheel. The failed run-flat was replaced with the same specification on the spot, which was the only real option open to them.
Reading the sidewalls on a car off Victoria Street showed a conventional tyre already fitted opposite a run-flat. We explained what that does to braking and matched the pair properly.
One tyre had been driven a long way with no pressure in it at all. The reinforced sidewall had done its job and was now scrap, so it was replaced rather than inspected hopefully.
The sidewall carries a marking from the maker, and the wording differs from brand to brand. If you are not sure, send us a photograph of the sidewall and we will tell you before anything is loaded onto the van.
It is not advisable on a car designed around them, particularly with no spare on board. If cost is the reason, we would rather talk it through properly than quietly fit something that changes how the car stops.
Sometimes, but only if it has not actually been run without pressure. Once it has carried the car flat the reinforcement has been cooked, and the casing cannot be trusted whatever the outside looks like.
Most replacements are finished inside the hour once we are with you, balancing included. The car stays in the space it is parked in, which around here is usually worth more than the time saved.
Ordinary saloon, SUV and 4x4 fitments are aboard as standard, and the less usual ones get sourced at pace. Reading us the numbers off your sidewall before we set off is what makes a single visit possible.
