The legal minimum is 1.6mm of tread across the central three quarters of the tyre, all the way round. That last part catches people out, because a tyre can look perfectly healthy on the outer edge and be down to the wear bars on the inner shoulder where nobody ever looks. On a car that spends its life climbing in and out of this valley, that inner edge is exactly where the wear goes.
When we come out, the wheel comes off and the whole tread face is measured, not just the bit you can see from the pavement. If the tyre is legal we tell you it is legal and how long it has left. If it is not, you get shown the gauge on the worn band before anything is replaced. Uneven wear also says something about the car, and where a pattern points at alignment rather than the tyre itself we will mention it, because fitting new rubber to a car that eats its inside edges only buys you time.
You will get a straight driveable-or-not answer before anything else happens. A broken tyre is usually a slow discovery rather than a bang: a kerb strike, a pothole on a road like the M40, a cut picked up who knows where, a bulge spotted while it sat parked up in Downley. Christmas Day in Downley, any day in Sands: the line is open. Ring at 3am from Totteridge and someone answers; Booker at noon is no different.

High Wycombe sits in a steep Chiltern valley and almost every route home is a climb or a descent, which loads the shoulders of a tyre far harder than flat towns do. That is why worn inner edges are such a common find here and why a glance at the outside proves very little. We measure the whole tread face on your drive in Totteridge or Sands, then give you the honest number rather than an opinion.
A car in Hazlemere looked fine from the kerb and was down to the bars on the inside of both fronts. The wheels came off, the wear was measured and two tyres went on.
A driver in Downley wanted the tyres checked before a long run. Three were sound, one was borderline, and only the borderline one was replaced.
A tyre near Booker was wearing in ridges rather than evenly. We replaced it and flagged the alignment, so the new one would not go the same way.
A twenty pence coin works. Put it in the main grooves in three places across the tyre and at several points around it. If the outer band of the coin shows, the tread is close to the limit and worth a proper measurement.
Usually alignment, sometimes suspension wear, and the steep camber changes on the roads out of the valley do not help. It is the edge you cannot see from the kerb, which is why it goes unnoticed.
Often yes, though we would rather match the pair on the same axle where the difference in tread is large. We will tell you which situation you are in rather than assume.
Yes, and we will show you the reading on the worn section. Nothing gets condemned on a glance, and the number is the number whether it suits us or not.
Yes. Car parks around Cressex are a regular stop for us, so the wheels come off where the car sits and the job is finished before you come out.
