Run-flat tyres vs normal tyres with a Tyron Multiband

Run-flat tyres let you keep driving for a limited distance after losing air, usually far enough to reach a workshop. The Tyron Multiband is a band fitted under a normal tyre that keeps the flat tyre on the rim, so you can drive a medium distance at reduced speed to a safe stop, but you cannot drive on to the next town.

They solve related problems in different ways. Both have real strengths, and the better choice depends on your car and how you use it.

How run-flat tyres work

A run-flat is a special tyre (see what is a run-flat tyre? for the basics). Goodyear describes reinforced shoulders and rubber inserts that keep supporting the car after air is lost. Because the tyre holds its shape, it stays usable for a while with no air in it.

Limits vary by make, model and vehicle. Goodyear gives about 50 miles at around 50 mph, which is roughly 80 km at 80 km/h, unless the vehicle handbook says otherwise. Bridgestone quotes up to 50 miles at up to 50 mph, about 80 km at 80 km/h, for its DriveGuard run-flat tyres. Going further or faster can cause excess heat and wear that weakens the tyre walls.

Run-flats must be used on vehicles with a tyre pressure monitoring system. A run-flat hides the handling cues that normally warn you of a puncture, so you need a dashboard alert to tell you it has happened.

How the Multiband works

Every rim has a groove called the wheel well, and air pressure is what keeps the tyre out of it. When the air goes, a flat tyre can drop into the well, come loose and slide off the rim. The Multiband fills that groove, so the tyre stays seated and you keep your steering and brakes.

The band works with your normal tyres. It is fitted in under an hour and refitted at each tyre change; any tyre fitter can do this, and we recommend a Tyron certified workshop. It is tested to 250 km/h. In TÜV testing, it completed 3 km at 80 km/h followed by 3 km at 50 km/h through a handling course and slalom. That is an emergency distance. It is enough to get out of immediate danger or off a busy road, and then you stop. See how it works for more detail.

Where run-flats are stronger

Distance. This is the clear advantage. After a puncture, a run-flat can often take you to a workshop or home, within the maker's limits. With a Multiband, you pull over and then change the wheel or call for recovery.

Convenience. There is nothing extra to fit, and any workshop that handles run-flats can change them. A Multiband is removed and refitted at each tyre change. Any tyre fitter can do it, and a Tyron certified workshop is recommended.

Stopping in a bad place. If you lose air somewhere you would rather not stop, a run-flat gives you more choice about where to pull over.

Where the Multiband is stronger

It works with normal tyres. You keep your choice of ordinary tyres, and the car's ride, handling and fuel use stay as they are. Run-flats have stiffer construction, which can make the ride firmer and noisier, depending on the tyre and the car.

Fit. The Multiband suits most cars, SUVs, MPVs and vans on normal tyres with 14 to 22 inch wheels. Low-profile tyres, with an aspect ratio of 45 or below, need a fitment check. Goodyear says run-flats can be fitted to standard alloy wheels, but only on vehicles with a pressure monitoring system.

Repairs. A normal tyre can have a normal puncture repair. Goodyear says not all run-flats can be repaired, although some of its models can be repaired by a qualified professional.

Replacement. Run-flats usually carry a price premium each time you replace them. A Multiband is bought once and reused, and it carries a 10-year warranty tied to the vehicle's chassis number.

What neither one does

Neither stops punctures or bursts. Both are short-term measures after a tyre fails, and in both cases the damaged tyre will need attention. Goodyear warns that driving outside the limits can also damage the wheel. Treat a tyre that has been driven flat on a Multiband as damaged: have it replaced or inspected by a tyre professional.

You still need your spare or a recovery plan with a Multiband. It does not replace your spare wheel or repair kit. Our guide to sealant, spare wheels and the Multiband covers how these fit together.

Which one suits you?

Run-flats may suit you if your car came with them, you drive long distances far from help, and being able to carry on after a puncture matters most to you.

A Multiband may suit you if your car is on normal tyres, you want to keep those tyres, and your main concern is keeping control and reaching a safe place after a burst.

If you are on run-flats now, the time to look at a Multiband is when their run-flats are due for replacement, and move to normal tyres. Check first that your car has a suitable spare or recovery plan. If you want to see what a Multiband would mean for your car, you can request a quote.
