How much do run-flattyres cost?
Run-flat tyres cost £100 to £275 per tyre before fitting in 2026, a 40 to 60 per cent premium over the same size in standard construction. Here is the price by size, the BMW and Mercedes marking codes, and when switching to standard tyres pays.
Price by size
Run-flat vs standard, per tyre
The premium is the number that matters when you are deciding whether to keep run-flats. It sits at 40 to 60 per cent across the common premium-German sizes. Prices are per tyre before fitting; add roughly £15 to £25 per tyre for fitting, balancing and disposal.
| Size | Common cars | Standard | Run-flat | Premium |
|---|---|---|---|---|
| 205/55 R16 | BMW 1 Series, Mini Cooper | £70-110 | £100-165 | +43-50% |
| 225/45 R17 | BMW 3 Series, Mercedes C-Class | £85-125 | £125-195 | +47-50% |
| 225/40 R18 | BMW 4 Series, Mercedes C Coupe | £100-145 | £145-220 | +45-52% |
| 255/35 R19 | BMW 5 Series, Mercedes E-Class | £125-175 | £180-275 | +44-57% |

Why run-flats cost 40 to 60 per cent more
A run-flat has a reinforced sidewall that carries the weight of the car when the tyre loses pressure. That lets you drive up to 50 miles at up to 50mph after a puncture, enough to reach a garage without a roadside change. The extra rubber and the stiffer, more complex construction are the direct reason for the price premium, and the smaller field of brands that make each size keeps prices from being competed down the way standard sizes are.
The premium is not the only extra cost. Because the deflated sidewall may have been overloaded, most fitters will not repair a run-flat that has been driven on flat, so a puncture that would be a £25 to £35 plug-and-patch on a standard tyre usually becomes a full replacement. Run-flats also wear slightly faster on average and the firmer ride is a comfort trade-off rather than a cash one.
Reading the sidewall
Run-flat and OE marking codes
When buying replacements, match both the run-flat construction and, on a car that was OE-fitted, the manufacturer approval marking. Fitting the wrong marking mixes tyres the car was not set up for.
| Marking | Brand / fit | What it means |
|---|---|---|
| RSC | BMW / MINI OE fit | Runflat System Component. BMW's approval marking; usually paired with a maker code (Bridgestone, Pirelli, etc.). |
| ★ (star) | BMW approved | BMW-approved tyre. On a run-flat size it is fitted alongside RSC. Not a run-flat marking on its own. |
| MOE / MOExtended | Mercedes-Benz OE fit | Mercedes Original Extended: the run-flat version of a Mercedes-approved tyre. |
| ZP | Michelin | Zero Pressure. Michelin's self-supporting run-flat construction. |
| SSR | Continental | Self-Supporting Runflat. Continental's run-flat line. |
| RFT | Bridgestone | Run-Flat Tyre. Bridgestone's OE run-flat marking; DriveGuard is the aftermarket range. |
| ROF | Goodyear / Dunlop | RunOnFlat. Also seen as EMT (Extended Mobility Technology) on older Goodyear stock. |
| r-f / Run Flat | Pirelli | Pirelli's run-flat marking; carries RSC when the fitment is BMW-specific. |
When switching to standard tyres pays
If your car has a spare wheel, a space-saver or a tyre repair kit in the boot, you can fit standard tyres instead of run-flats and save £40 to £80 per tyre on every replacement, plus a softer ride. Many BMW and Mercedes owners without a spare can add a space-saver kit and then switch. If there is no spare and no repair kit, the car is relying on the run-flat construction to get you home safely after a puncture, so keep run-flats. Check the boot before you decide.
Common questions
Run-flat tyre cost FAQ
How much do run-flat tyres cost in the UK in 2026?
A run-flat tyre costs roughly £100 to £275 per tyre before fitting in 2026, depending on size and brand. That is a 40 to 60 per cent premium over the equivalent standard tyre. A 205/55 R16 (BMW 1 Series, Mini) runs £100 to £165; a 225/45 R17 (BMW 3 Series, C-Class) £125 to £195; a 255/35 R19 (5 Series, E-Class) £180 to £275. A full set of four therefore lands between about £400 and £1,100 before fitting.
Why do run-flat tyres cost more than standard tyres?
Run-flats have a reinforced sidewall that supports the weight of the car after a puncture, letting you drive up to 50 miles at up to 50mph to reach a garage. That extra construction uses more material and a more complex build, which is why they cost 40 to 60 per cent more than a standard tyre in the same size. The choice of brands and models is also smaller, so there is less competition on price.
How much do BMW run-flat tyres cost?
BMW run-flats carry the RSC (Runflat System Component) marking and price the same as other premium run-flats in the size: around £100 to £165 for a 1 Series (205/55 R16), £125 to £195 for a 3 Series (225/45 R17) and £180 to £275 for a 5 Series (255/35 R19). Fit the correct RSC-marked tyre unless your car has a spare wheel and you have chosen to switch to standard tyres.
Can I fit standard tyres instead of run-flats?
Only if the car can safely cope with a puncture without run-flat support, which in practice means it has a spare wheel, a space-saver or a tyre repair kit. Many BMW and Mercedes models can have a space-saver added, after which you can fit standard tyres and save £40 to £80 per tyre on every replacement. If the car has no spare and no repair kit, it relies on the run-flat construction and you should keep run-flats.
Can run-flat tyres be repaired?
In most cases no. Once a run-flat has been driven on while deflated, the sidewall structure may have been compromised in a way that cannot be reliably inspected, and most manufacturers and fitters will not repair it. That is part of the running cost: a puncture that would be a £25 to £35 repair on a standard tyre usually means a full replacement on a run-flat.
