Most complaints about a new tyre losing air have nothing to do with the tyre. They are about the bead, the wire-cored edge that has to clamp against the rim and stay clamped. It only does that if three things are right: the seat on the wheel is clean, the bead is properly lubricated as it goes on, and the tyre is inflated hard enough for both sides to pop home before the pressure is dropped back to normal.
Alloy wheels corrode where nobody can see it. Under an old tyre the seat goes chalky and pitted, and a new tyre dropped straight onto that will weep slowly and turn up as a mystery a fortnight later. So the seat gets wire-brushed back to clean metal, proper tyre paste goes on rather than washing-up liquid, a new valve goes in, and only then is the tyre seated and set. On an urgent job that costs a few extra minutes at the kerb. It is the difference between a tyre that holds from the first mile and one that has you back on the phone.
An unusual size is worth mentioning early rather than late. Once it is settled, it is fitted and balanced where the car is parked in N14, with the valve checked and the pressures set to the manufacturer figure. Old tyres leave Oakwood, Cockfosters and N14 with us, every time. You watch it happen in Grange Park, or at the kerb in Osidge. A N14 address in Winchmore Hill and one in Oakwood are the same round.

Cars in N14 cover short distances and then stand still for long stretches, and in January they collect a coating of road salt that sits on the wheels and never gets washed off. That is exactly the recipe for a corroded bead seat. It is why seats get cleaned here as a matter of routine rather than only when a wheel looks obviously bad.
The tyre came off after a sidewall cut and the wheel seat underneath was white with corrosion. Cleaning it back took longer than fitting the replacement, and the car went away with nothing weeping at the rim.
A late afternoon call, a tyre well beyond saving and a hard deadline. Correct size off the van, seated, balanced and torqued to the figure in the handbook, with the price agreed before we set off.
A hit on a kerb had rolled the rim edge slightly and the tyre had been losing air ever since. We dressed the lip, fitted a replacement and left it soaped so the owner could see nothing was bubbling.
Common car, SUV and 4x4 fitments are carried as stock, so most urgent calls are dealt with on the first visit. Read us the numbers off the sidewall when you ring and we will tell you straight away whether it is aboard.
No. Budget, mid-range and premium all get carried, and short notice is not the same thing as buying badly. We will tell you what the extra money actually buys in wet braking and tread life, then you choose.
You feel it, or rather you do not. A wheel that has not been balanced shows up as a shimmy through the steering at around fifty. Every wheel goes on the balancer at the car before it is bolted back up.
One is fine if the other tyre on that axle is a similar make with plenty of tread left. If it is nearly worn out, or a different pattern, doing the pair keeps grip even side to side. We measure both and tell you which it is.
It goes in the van and away for recycling. Nothing is left leaning against a wall or rolled into a hedge, which matters more than it sounds when the work has been done on somebody's driveway.
