A tyre fitted the wrong way round works perfectly well. That is the trouble with it. The car drives off, nothing rattles, nothing warns you, and the fault only reveals itself on a wet road when the tread is pushing water in a direction it was never designed to. Two markings on the wall decide this and they mean different things. A directional tyre carries an arrow and a word telling you which way it must turn. An asymmetric one carries Outside on one shoulder and Inside on the other.
Directional tread is cut in a V that funnels water backwards out of the contact patch as the wheel rotates. Run it in reverse and the V gathers water instead of clearing it, so wet braking distances stretch while the driver has no idea anything has changed. Asymmetric tread is a different idea altogether. The outer half is built with big stiff blocks for cornering and the inner half is grooved for drainage, so mounting it inside out puts the soft side where the load goes. Both mistakes are easy to make and invisible once the wheel is back on.
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 Canbury and fit it where it stands, balanced, valve checked, pressures set. Whether it is Coombe in rush hour or Kingston Hall Road at midnight, we answer. On Richmond Road, day or night, Kingston town centre included, arrival across KT1 runs 30 to 60 minutes. A KT1 address in Canbury and one in Hampton Wick are the same round.

Wet grip is the thing worth protecting in a town that spends its life on the damp side of the Thames and inches through the Clarence Street one ways whenever it rains. A tyre mounted against its own markings takes that grip away quietly and gives nothing back. Fitting at the kerb makes the check no harder, because the wall is read before the bead ever goes on.
A full size spare taken out of the boot can easily end up on the wrong side of the car, and on directional rubber that puts the tread backwards. If your spare has been on for a while and wet weather feels vague through the steering, that is worth checking. Correcting it is a short piece of work.
On an asymmetric tyre the lettering reading Outside has to be the lettering you can see standing next to the car in Hampton Wick or anywhere else. It is the easiest thing on this list to check yourself, and the most common thing found wrong on a car fitted somewhere in a hurry.
Directional tyres cannot swap sides without coming off the rim and being remounted the other way. So on a car where one has gone on backwards, the remedy is a demount rather than a shuffle of wheels. The machine travels with us precisely so that stays a small job.
Stand at the wheel and read the wall. An arrow beside the word Rotation means directional. The words Outside or Inside mean asymmetric. Some tyres are both, and those must satisfy the arrow and the facing at once, which pins them to one corner of the car.
There is no ticket waiting for you, which is part of why it goes unnoticed for years. The cost is paid in wet braking instead, and it is paid on the one day you needed the tyre most. That is the reason to correct it, rather than any rule.
Each tyre only has to be correct for the corner it occupies, so a single replacement is entirely normal. What we would question is putting a badly mismatched tread pattern across the front axle, because the car then brakes unevenly in the wet.
Across an axle it does, because the two share the braking and the steering and different patterns deliver different grip. Front to rear it matters much less. Where an exact match is not available, you will hear what the compromise is before anything is fitted.
There is no cut off point. We run through the night and across the holidays, so a tyre that fails coming back over Kingston Bridge at midnight gets the same visit as one that fails at noon. Card and contactless payment at the car when the work is done.
