What is a Run Flat Tyre?

A run flat tyre is designed with reinforced sidewalls that help support the car's weight and allows it to continue to run after a loss of pressure.

Motorists can identify if their car has run flat tyres by checking the sidewall coding.

Buying puncture-proof tyres gives you more comfort and peace of mind. In practice, you no longer need to change a flat tyre at the roadside. However, it is important to understand that you cannot ignore the puncture and continue to drive for a long time. You should visit a garage as soon as possible.

If your car has run flat tyres, you can drive up to 80 more km at a maximum speed of 80 km/h.

These figures may vary depending on tyre profiles and manufacturers. To put it concisely, your driving range will depend on the load of your vehicle, the outside temperature, and the road.

Each manufacturer is free to decide whether or not to repair run flat tyres.

Run flat tyres repair service is technically possible, but not in all cases. Get professional advice! 
 
MICHELIN run flat tyres can be repaired only once by a professional under the same conditions and by following the same inspection and repair procedure as non-ZP tyres, except for those whose sidewall explicitly states that they cannot be repaired. 

Run flat tyres can be installed at home, but it's important to know what you're doing. Removing a tyre from a rim and properly fitting a new one before inflating it can be quite challenging. For most car owners, it's best to find a dealer who can handle the job instead.

If your spare tyre is a run flat tyre, it can be replaced in the same way as a regular tyre.

Safety

• You can control the vehicle confidently, even when you lose the pressure or encounter a puncture.

• Reduced risk of blowout and tyre coming off the rim.

• You can continue driving at moderate speed to a nearby garage instead of stopping to change the tyre on a busy road, which can be dangerous.
  

Convenience

• No immediate replacement of the flat tyre.

• Slight space saving in the trunk of the vehicle since the spare tyre is no longer necessary. That reduces overall weight in the vehicle, too.

Savings

• No need to invest in a spare tyre, nor in the equipment needed to change a tyre.

MICHELIN run flat tyres may only be mounted on rims with double hump and vehicles for which the manufacturer has approved a self-supporting tyre mount.

We don’t recommend mounting a self-supporting tyre on a vehicle that wasn’t originally designed for it because such tyres have specific needs regarding weight and stiffness.

The vehicle must be equipped with a pressure monitoring system (TPMS) to warn the motorist in case of pressure drop. We recommend equipping your vehicle with 4 MICHELIN ZP tyres to maximise the performance of run flat technology.

Whether you want to fit run flat tyres on your vehicle, it is important to know that other options are available.

When using snow chains, MICHELIN recommends chains with automatic tensioners which adjust better to deflated tyres.
