Mobile Tyre Fitting in Keynsham

What we can do in Keynsham

• Mobile tyre fitting — supply and fit a replacement at your home, workplace or the roadside, including balancing and disposal of the old casing.
• Mobile puncture repair — where the damage is inside the repairable area of the tread, a repair is cheaper and quicker than replacement.
• Commercial tyre fitting — vans, minibuses and other light commercial vehicles.

Before we arrive

• Find your locking wheel nut key. Without it the wheel cannot come off. It is usually in the glovebox, the boot well, or with the spare.
• Read your tyre size off the sidewall, for example 205/55 R16 91V, so we arrive with the right tyre rather than making a second trip.
• If you are on a motorway or dual carriageway, get as far left as you can or into a refuge, then everyone out through the passenger doors, over the barrier and well back from the carriageway — not in the car. Ring with the junction number and your direction of travel.
• Describe where you are, not just your postcode. A junction number, a bay number, a farm, a pub or a bridge puts us on the spot far faster — rural postcodes can cover a mile of near-identical lane. We bring our own lighting, so darkness is not a problem.

More detail in our guides on what to do with a flat tyre on the motorway and checking your tread depth.

Repair or replace

Whether a tyre can be repaired is decided by where the damage is, not by how big the hole looks. Damage inside the central three-quarters of the tread, up to 6mm across, is repairable under BS AU 159. Damage in the shoulder or the sidewall is not, at any size — there is no way to reinforce a sidewall that flexes on every revolution.

The other thing that rules out a repair is having driven on the tyre flat. A short distance is enough: the sidewall folds under the rim and the internal cords break. That often does not deflate the tyre at the time — it shows up days later as a soft rounded bulge, and a tyre in that condition has to be replaced whatever the original puncture looked like.

How the damage was made matters as much as where it is. A nail or a screw pierces, leaving a neat hole that is usually well within the limit. Flint, crushed stone, quarry aggregate and dropped stainless fixings cut instead — a gouge or a tear rather than a puncture — and a cut frequently exceeds the repairable size even when it lands squarely in the middle of the tread. That is why we take the tyre off and look inside before telling you either way, rather than judging it from the outside.

Impact damage behaves the same way. A pothole or a kerb taken at speed compresses the suspension fully and pinches the sidewall between the rim and the obstacle. If that has happened, check both tyres on that side — the rear takes the same hit a fraction of a second after the front — and look for a bulge rather than for a hole.

We carry both outcomes to every job, so a repair that turns out not to be safe does not become a second visit.

Age and wear

Tread depth is not the only thing that retires a tyre. Rubber hardens as it ages whatever the mileage, which is why a caravan, motorhome, trailer or second car can carry almost full tread on a casing that is well past useful life. The four-digit date code on the sidewall gives the week and year it was made — our guide on how long tyres last covers where the line falls.

Depth matters most in standing water. The legal minimum is 1.6mm across the central three-quarters, but a tyre's ability to clear water falls off well above that — by about 3mm you are losing it noticeably, and aquaplaning starts at lower speeds than most drivers expect. Our tread depth guide covers checking it with a 20p coin in about a minute.

Wear patterns are worth reading too. Both outer shoulders going before the middle usually means underinflation, or a lot of cornering and hill descent; one edge alone is more often alignment. We will tell you which it looks like when we are there — see uneven tyre wear for the full picture.

Vans and light commercials

A van needs a tyre carrying the C marking and the correct load index. That is not interchangeable with a passenger tyre of the same nominal size, whatever may have been fitted before — the casing is built to carry more, and a loaded van on passenger-rated tyres is running outside the rating.

Tell us whether the van is loaded when you ring, and we will bring the right fitment first time. Details of what we carry are on the commercial tyres page.

How the repair is done

The wheel comes off, the tyre comes off the rim, and the inside of the casing is inspected before anything else happens. The puncture is then repaired from within using a combined plug and patch, and the wheel is balanced before it goes back on.

That inspection is the part that matters. An external plug pushed into the tread without removing the tyre is a get-you-home measure: it can seal the hole while leaving damage inside the casing entirely undetected, and that damage is what causes tyres to fail later at speed. It is the same job a garage does, done where the vehicle already is.

A slow leak with no puncture to find

A tyre that loses air over days with nothing in the tread has usually failed at the seal rather than the surface — a corroded alloy bead seat, or a perished valve stem. Neither can be found with the tyre still on the rim, and neither is fixed by topping the pressure up.

It typically announces itself on the first cold morning of the year. Cold air contracts, dropping the pressure a few PSI, and a leak that was tolerable through mild weather is a visibly flat tyre by the time you come out to the car. The fix is the tyre off the rim, the sealing face cleaned back to sound metal, and a new valve.

Working conditions around Keynsham

Standing water. We will not drive a van through water of unknown depth, so if a road is flooded we may ask to meet you on higher ground. Tell us which road you are on when you ring and we will work out the approach before setting off rather than after.

Station and workplace car parks. A commuter car park is where slow punctures hide. Eleven hours standing with a short drive at each end means you never drive far enough or fast enough to feel a tyre going down — so it presents as a flat at six in the evening rather than as a soft one in the morning. These are also the easiest jobs we do: the car is stationary for hours, the surface is flat, and there is room to work. Leave us the bay number and where the locking wheel nut key lives and it is finished before you are back, which beats finding it flat at the end of the day.

Trade and industrial estates. Yard surfaces collect banding, pallet nails and dropped fixings, and that sort of debris cuts and gouges rather than piercing cleanly — damage that frequently falls outside the repairable size limit even when it lands in the middle of the tread. We keep commercial fitments on the van for the vehicles these estates run.

Common questions in Keynsham

Bypass or the old road — does it matter?

At peak, yes. They run close together and the queue through the middle of the town is substantial when the bypass is moving.

The riverside road is flooded.

Tell us which side of the Avon you are on. When it is up the crossings carry everything and that decides the route.

I left it at the station this morning and it is flat now.

That is the good version — it went down standing still, so the inside is normally sound and a repair usually does it.

Can you work outside my house?

Depends on the road. The centre is Victorian terraces with on-street parking; the outer estates mostly have driveways.

Do you cover Saltford, Whitchurch and Chew Magna?

Yes, across BS31, BS39 and BS40.
