TPMS warning light on? Driven on a flat run-flat? We come to you — at home, work or roadside — and replace your run-flat tyre on the spot. BMW, Mini, Mercedes and all run-flat vehicles covered. Available 24/7.
Run-flat tyres have reinforced sidewalls that allow the tyre to continue supporting the vehicle's weight even when completely deflated. Unlike a standard tyre — which immediately becomes undriveable when it loses pressure — a run-flat tyre allows you to continue driving at reduced speed, typically up to 50mph, for up to 50 miles after a puncture. This gives you enough range to reach a safe location or a fitting service without needing a spare wheel, which is why most vehicles fitted with run-flats from the factory do not carry a spare at all.
You can identify a run-flat tyre by the markings on its sidewall. Different manufacturers use different codes: RFT (Bridgestone), ROF (Goodyear), EMT (Michelin Extended Mobility Tyre), ZP (Continental Zero Pressure), or SSR (Dunlop Self-Supporting Runflat). If your vehicle has no spare wheel and your car uses a tyre pressure monitoring system (TPMS) as its primary warning system, it almost certainly runs on run-flat tyres. BMW, Mini, Mercedes-Benz and some Lexus models are the most common vehicles using run-flat tyres as original equipment across the West Midlands.
When your tyre pressure monitoring system warning light illuminates — the horseshoe-shaped symbol with an exclamation mark — your run-flat tyre has lost pressure and the clock has started. The 50-mile, 50mph run-flat limit is a guideline under good conditions, not a guarantee. Heat, vehicle weight, road conditions, and the original cause of the pressure loss all affect how much range you actually have. Reduce your speed immediately and avoid motorway speeds from the moment the light comes on.
Do not continue your journey normally. Do not assume the TPMS sensor is faulty and ignore the light. Call TT Mobile Tyre Fitting 24/7 on 07762 455291 and we will come to your location across Birmingham, Wolverhampton, Walsall, Dudley, Coventry and the wider West Midlands. We can often reach you before you reach the 50-mile limit — at which point the tyre must not be driven on any further regardless of where you are.
In most cases, no — and we will always tell you this honestly rather than carry out a repair that is not safe. The reason is straightforward: when a run-flat tyre is driven on while fully deflated, the reinforced sidewall bears the vehicle's entire weight without the support of pressurised air. This causes internal structural damage — flexing, heat damage and cord distortion — that cannot be seen from the outside. Even if the visible puncture damage appears minor, the internal structure may be compromised in ways that make the tyre unsafe at speed.
Most tyre manufacturers and the British tyre industry's own guidelines advise that run-flat tyres should be replaced rather than repaired after any loss of pressure. We will inspect every run-flat tyre we remove and give you an honest assessment. If there is any doubt about the internal structure, we will always recommend replacement over repair.
Technically yes — a standard tyre of the correct size and load/speed rating can be fitted to a vehicle designed for run-flats. However, this is not advisable on vehicles that were factory-fitted with run-flats as original equipment, for a simple practical reason: these vehicles have no spare wheel. If a standard replacement tyre gets a puncture, you will be stranded with no run-flat capability and no spare. You would also need to carry a tyre inflation kit or arrange recovery, neither of which is as convenient as the run-flat setup the vehicle was designed around.
If you decide to switch from run-flat to standard tyres, it is advisable to replace all four at the same time for consistency in handling and grip levels. Mixing run-flat and standard tyres on the same axle is not recommended. We will discuss all of these options with you when you call — there is no single right answer and it depends on your vehicle, your driving patterns and your budget.
We carry a range of run-flat tyres in our van covering the most popular sizes fitted to BMW, Mini and Mercedes-Benz vehicles across the West Midlands. Run-flat sizes we regularly stock include the common BMW fitments — 225/45 R17, 225/50 R17, 205/55 R16, 245/45 R18, 255/40 R18 and others — as well as Mini and Mercedes common sizes. Brands we stock for run-flat fitments include Bridgestone, Continental, Dunlop and Pirelli, which manufacture the majority of original-equipment run-flat tyres for these vehicles.
Less common run-flat sizes may need to be ordered. If you call us with your tyre size — found on the tyre sidewall in the format 225/45 R17 91W — we will confirm availability immediately. In most cases for popular BMW and Mini sizes, we will have your tyre in the van and can reach you within 30 to 60 minutes across the West Midlands.
The traditional advice after a run-flat puncture was to drive carefully to the nearest BMW dealer or authorised tyre centre. This is inconvenient at best and impossible at worst — if you are on the M6 near Birmingham at midnight with a TPMS warning, a dealership is not an option. We are. We come to wherever your vehicle is — your home in Sutton Coldfield, your workplace in Solihull, a car park in Wolverhampton, or the roadside on the M42. You do not need to organise recovery or arrange alternative transport.
We carry professional balancing equipment in our van and balance every run-flat tyre before leaving your location. This is important with run-flat tyres as their stiffer sidewall can make imbalances more noticeable at speed. Your car's TPMS sensors are retained during our fitting process — we do not remove or damage them.
