Everything about a roadside replacement is decided by a line of characters moulded into the sidewall. Something like 195/65 R15 91T.
All of it has to be respected. Fitting a lower load index than the manufacturer specified is not legal, and on a van running C rated tyres it is the difference between a tyre that carries the payload and one that does not. Dropping a speed rating on a car built for a higher one is the same class of error. Width and profile have to match the other tyre on the axle, and so does construction.
Read us the whole string when you ring, letters included, and the right tyre travels out with the fitter the first time.
A split found while checking the car before a long drive is the good version of this problem. So the tyre comes to the car: correct size matched to the wheel, fitted and balanced where it stands in Tyttenhanger, pressures set for the load you are about to put in it. A 4am Shenley call and a noon Frogmore call reach the same fitter. Whether it is Tyttenhanger in rush hour or the A414 at midnight, we answer.

Between the M25, the A414 and the A1081, London Colney generates a steady run of tyres that cannot be saved, and a good number of them are on vans rather than cars. Load ratings are where those go wrong, so if the sidewall carries a C or an XL marking, mention it when you ring and the right construction goes out on the van.
A works van at Frogmore had lost a rear, and the obvious car tyre in the same nominal size would not have carried the load. The reinforced version went out instead. It is a detail that gets missed, and it matters most on exactly the vehicles that are hardest to leave standing.
A blowout on the A414 had taken one rear tyre and its partner was worn well past it on a different pattern. Replacing the pair was the sensible answer there, and the reasoning was explained rather than presented as a rule that had to be accepted.
A driver stopped near junction 22 read out the full size while standing safely behind the barrier. The tyre was on the van before it left, so the job took one visit. Reading only the first three numbers is what turns these into two.

Really responsive and pleasant too. I WhatsApped in the morning rush hour, got an honest quote, an updated ETA with traffic, and he changed my tyre. Would highly recommend.
Great service, fast and available. My tyre is not one an ordinary garage has in stock, but they just went to get the tyre and replaced it on a Sunday. Recommend.
Came and sorted a replacement tire within half an hour or so. Fast and efficient service.
On the outer sidewall, moulded into the rubber, usually the longest run of numbers and letters on the tyre. If the car is somewhere safe, walk round and read the whole line. If reading it would mean stepping towards moving traffic, do not, and we will work from the registration instead.
You can fit different brands across an axle provided size, construction and ratings match, and plenty of people do. What you should not do is mix a run flat with a conventional tyre, or pair very different tread patterns, because the two sides then behave differently under braking.
It marks a commercial construction with a higher load capacity and usually a higher inflation pressure. A passenger car tyre in the same nominal size is not a substitute even though it will physically fit, so a C rated version comes out for a van.
There and then. The tyre machine, the balancer and the torque wrench all travel on the van, so the wheel never leaves the car park or the verge. That is the whole point of the service and it is why nothing has to be collected later.
It comes away with us for recycling. There is nothing to store, nothing to take to a tip and nothing left on the verge, which matters more than it sounds on the roads around here.
