Find the real fault first
Mobile Tyre Repair in Epsom
Not every tyre losing air has a nail in it. We diagnose the actual cause, whether that is the valve, the rim seat, a sensor seal or the casing itself, then fix the right thing.

24/7Including nights and Sundays
Overview
Most slow leaks are not punctures
Drivers come to us convinced they have a puncture because the car needs topping up every fortnight. Quite often there is no nail anywhere in the tyre. A tyre can lose pressure through a perished rubber valve, through corrosion on the rim where the bead seats, through a leaking TPMS sensor seal, through a cracked or buckled wheel, or through the casing itself.
That is why this service is diagnostic before it is mechanical. We pressure the wheel and test it properly rather than glancing at the tread, because a bead-seat leak or a valve seep is invisible until you look for it.
This is also the service where we make the repair-or-replace call on more complicated damage: kerb tears, cuts you are not sure about, vibration after hitting a pothole on Kiln Lane, or a tyre that was run flat for a mile before you realised.
What's included
Faults we find and fix on site
Five common causes of a tyre that will not hold pressure, and what each one needs.
Perished or split valve
Rubber valves harden and crack with age and UV.
Corroded rim bead seat
Alloy wheels oxidise where the tyre bead sits, especially on cars that see winter salt.
Leaking TPMS sensor seal
The sensor's grommet and nut seal perish.
Genuine tread puncture
Found by water test, then plug-and-patched if it is in the zone.
Casing or rim damage
Buckled rims, kerb cuts and sidewall bulges.
Vibration after an impact
A pothole strike can throw a wheel out of balance or bend it.
Step by step
How we diagnose a tyre that keeps going down
Working from the cheapest and most likely cause to the most expensive, so you are not paying for the wrong fix.
Pressures checked all round
Starting figures across all four, checked against the door pillar plate.
Valve, sensor and rim tested
The most common and cheapest causes first.
Tyre demounted if needed
A casing leak means the tyre comes off, so the liner can be read.
Fixed, balanced, refitted
Valve, sensor kit, rim reseal or a repair, then balanced and torqued.
When to call
Symptoms worth calling us about
If any of these describe your car, the problem will not fix itself.
Topping up every week or two
A steady, repeatable loss.
TPMS light on for one corner
The system is telling you that wheel is losing pressure faster than the others.
Vibration that appeared suddenly
Usually a thrown balance weight or an impact-bent rim rather than the tyre itself.
A hiss you can hear when parked
Fast enough to hear means fast enough to leave you flat overnight.
Cost and detail
What the repair costs depends on what is wrong
We diagnose first and quote the specific fix, so you are not paying for work the car does not need.
Valve replacementThe cheapest outcome and a common one.
TPMS service kitNew grommet, nut and core for the sensor, plus a re-register where the vehicle requires it.
Rim bead-seat clean and resealBead broken, corrosion cleaned back, sealed and refitted.
Combination puncture repairWhere the injury qualifies under BS AU 159.
Rebalance onlyIf the fault is vibration rather than pressure loss, often all that is needed is a proper rebalance.
Replacement quoted honestlyBeyond repair means we quote a replacement, not a patch over it.

Why us
Why diagnosis matters more than the patch
We find the cause, not the symptom
Patching a rim leak wastes your money and still loses air.
The cheapest correct fix first
A valve costs a fraction of a repair, a repair a fraction of a tyre.
We will not sign off a bad casing
If we do not trust the tyre, we say so, and we explain exactly why.
Proper equipment on board
Bead breaker, changer and balancer on board, so the tyre comes off.
Same visit, no second appointment
Diagnosis and repair happen in one callout wherever the parts allow.
Explained in plain English
You get told what was wrong and why, not just handed a bill.

Questions
Mobile Tyre Repair in Epsom: frequently asked questions
Straight answers to what customers ask before booking.
My tyre keeps going down but I cannot find a nail. What is it?
Very likely one of four things: a perished rubber valve, corrosion on the alloy rim where the tyre bead seats, a leaking TPMS sensor seal, or a small casing porosity.
What is the difference between tyre repair and puncture repair?
Puncture repair is the specific job of sealing a tread injury with a combination plug-and-patch.
How much pressure loss is normal?
A healthy tyre loses roughly one to two psi a month through normal permeation, and pressures also drop about one psi for every five and a half degrees the temperature falls.
Can you fix a leak where the tyre meets the wheel?
Yes, in most cases. That is a bead-seat leak, usually caused by corrosion on an alloy rim.
My TPMS light keeps coming on even after I inflate the tyres. Why?
Either one tyre genuinely is losing pressure faster than the others, or a sensor has failed. TPMS sensors have an internal battery that typically lasts seven to ten years and cannot be replaced separately.
Is it worth repairing an old tyre?
If the tread is well above 3mm and the casing is under about six years old, usually yes.
Can you repair a buckled or cracked alloy wheel?
No, and we would not attempt to on the roadside. A cracked alloy is a structural failure and a buckled rim needs specialist straightening equipment.
Do you come out for a tyre repair at night?
Yes. We run twenty four hour callouts across Epsom, Ewell, Ashtead, Stoneleigh, Epsom Downs and Epsom Common.
