Once a tyre is beyond saving, everything turns on getting the correct replacement to the car, and around Ascot correct can be a narrow target.
So the phone call does the real work. Read us the full string off the sidewall, tell us the make and model, and mention any letters following the size, an N, an MO, an AO or a star, because those denote a specification developed for that particular vehicle. If the car sits on run-flats, replacing one with a conventional tyre changes how it behaves and leaves you without run-flat capability on that corner.
With that settled, the right tyre travels out, goes on at the roadside, is balanced, and the inflation figures are taken from the vehicle plate.
The gap between "needs replacing" and "needs replacing now" is usually a journey you cannot move. A run on the B3020 on a tyre that is already down to the markers is not a risk worth taking. Old tyres leave Winkfield, Sunninghill and Berkshire with us, every time. You watch it happen in Sunningdale, or at the kerb in Cheapside.

More cars around Ascot run specialist fitments than in most of the towns we cover: run-flats, approved markings and staggered sets are ordinary here rather than exceptional. That makes reading the sidewall the most useful two minutes of the entire job. Give us the numbers and the letters and the right tyre arrives with the fitter, first time.
A car in Sunningdale needed one rear. The sidewall carried a star, which denotes a specification approved for that manufacturer. The standard version would have been cheaper and would not have matched the three tyres already on the car.
A driver in South Ascot with no spare and no repair kit had been offered a conventional tyre elsewhere. That would have left the car without the capability it was designed around, so the matching run-flat went on instead.
A vehicle at Cheapside ran 275 section rears against 245 fronts. Confirming both sizes over the phone meant the right one was aboard. Assuming a single size across a staggered set is the commonest cause of a wasted visit there is.

Very quick call out and replace time, very good price and very polite.
I clipped the kerb when parking, damaging the wall of my tyre. I contacted Fast Tyre at 21:37 and by 23:40 I had a new tyre fitted. Excellent service and both boys were friendly and efficient.
5 star without a doubt! Called this morning with a complete flat tyre in N13 and within 30 minutes Abdul arrived and changed it. He also checked all 4 tyres and showed me one was completely bald and dangerous to drive.
The last letter is the speed rating and the digits before it the load index. Extra markings such as XL, RFT, MO, AO, N or a star indicate reinforced construction, run-flat capability or a manufacturer specific development. All of them affect what should go on.
Physically it can be done, and we would advise against it. The car loses the ability to run deflated on that corner and the stiffness across the axle no longer matches. Where cost is the issue, changing the pair is the sound version of that idea.
Many of them, and the mix around Ascot means we plan for it. Very wide, very low profile or approved fitment tyres occasionally need sourcing, in which case you get told on the phone and given a realistic timescale rather than a hopeful one.
It is, where the manufacturer specified the car that way, which is the case on a fair number of vehicles here. What is not acceptable is different sizes across the same axle, or a size the car was never designed to carry.
It is handled as part of the fit. Valve mounted sensors are transferred across and checked, and the system is reset where the car requires it, so you are not driving away with a warning light left glowing on the dashboard.
