The size on the sidewall is only the first three numbers of the answer. After 225/45R17 comes something like 94Y, and those two markings decide whether a tyre is legal on your car at all. The 94 is the load index, the weight that one tyre is rated to carry. The Y is the speed rating. Fit a lower load index because it was what somebody had on the shelf and you have quietly downgraded the car, which matters most on a heavier SUV or 4x4 where the margin was never generous.
This comes up on urgent jobs more than planned ones, because urgency is what tempts people into accepting a near-enough fitment. We read the full code off the tyre coming off and match it, or better it, and if the correct one is not aboard we say so rather than fit something that nearly fits.
The other three tyres get checked on every emergency replacement, and it is not padding. The immediate job stays simple: correct size brought to the car in Highams Park, fitted and balanced where it stands, valve checked, pressures set. A 4am Wood Street call and a noon St James Street call reach the same fitter. Whether it is Blackhorse Road in rush hour or Forest Road at midnight, we answer. Parked near Lloyd Park or tucked into Highams Park, it is the same visit.

A lot of the emergency changes we do around Blackhorse Road and Wood Street are on cars that were fine yesterday and impossible today. The bit worth remembering is that the sidewall of the tyre you are replacing carries the full specification, so a photograph of it on your phone answers every question we would otherwise have to ask you twice.
It happens when somebody matched the width and the profile and stopped reading. The tyre carries the vehicle until the day it is loaded and warm, and then it does not. We check the load index against the plate before anything comes out of the van.
A single odd tyre changes how that corner behaves under braking and heat, and it will not match its partner across the axle. If the other three are H rated, the fourth is not going in as a T because it was handy.
Forest Road feeds towards the M11 and drivers leaving E17 for a long trip are exactly the ones who cannot afford a compromise fitment. Sustained motorway speed is where an under-rated tyre shows what it is.
Two places. The plate in the driver's door shut lists what the vehicle was built for, and the tyre currently on the car carries its own code on the sidewall. Read us either and we will match it.
Yes, going up is fine. A tyre rated for more weight or more speed than the car needs is not a problem. Going down is, and that is the one we will not do.
Common car, SUV and 4x4 sizes are aboard as standard, so most urgent jobs in Walthamstow are finished in the one visit. Anything unusual we will tell you about on the phone rather than after we have arrived.
Usually yes, provided the new one matches the specification and the tyre across the same axle is in reasonable condition. If the pair is badly mismatched in depth we will say so and let you decide.
It goes with us for recycling. Nothing is left propped against a wall behind you, and if the wear pattern on it tells us something useful about the car, you get told that before it goes in the van.
