At a glance
Why does a tyre keep going flat with no puncture?
A tyre that keeps losing air without a nail or screw in it often has a leaking valve. The rubber valve stem perishes with age and weather, and the valve core can loosen or fail, letting air escape slowly. Other common causes are a leak where the tyre seals against the rim, or a crack in the wheel. King of Tyres comes to the car, finds where the air is escaping, and replaces the valve on the spot when that is the cause. If the leak is somewhere else, the technician explains what was found and the options before doing any work. The service runs 24/7 across North West London, Hertfordshire and the M1/M25 from 183b Edgware Road, NW9. Call or WhatsApp 07710 006882 with your location and registration, and the price is confirmed before anyone sets off.

Questions
Tyre valve questions
If a tyre slowly loses pressure and there is no nail or visible damage, the valve is a common cause. We check the tyre and the valve to find the leak before we replace anything.
Yes. We check all four tyres, find any leak and set the correct pressures.
It is good practice to fit a new valve with every new tyre, because old rubber valves perish and can start to leak.
Across North West London we are with you in 30 minutes or less. Further out in Hertfordshire or on the M1/M25 it can take a little longer. We give you a realistic arrival time on the phone before we set off.
