Mobile Run-Flat Tyre Fitting & Replacement

Recognise the tyre before relying on it

Run-flat tyres use a construction intended to provide limited mobility after pressure loss. Their identifying markings vary between manufacturers. A tyre pressure warning does not by itself prove that the vehicle is fitted with run-flat tyres.

Check the handbook and tyre markings when it is safe. If you cannot confirm the tyre type or the applicable restrictions, stop the journey safely and ask for help.

Pressure-loss limits are specific

Permitted distance and speed depend on the tyre and vehicle manufacturer instructions and the circumstances. Load, damage and how far the tyre has already travelled can affect whether further use is possible.

A run-flat is not automatically safe after a puncture. Follow the instructions for your actual vehicle and tyre, and do not continue if the tyre or handling suggests a serious problem.

Assessment and replacement

Repairability varies by manufacturer and by tyre condition. Use after pressure loss may cause damage that is not visible from outside. Explain the distance driven since the warning or puncture so the technician can assess the situation.

If replacement is needed, discuss a compatible new tyre and availability. Mixing or changing tyre technology should not be treated as a simple interchangeable option.

What to share

A readable sidewall photo is useful from a safe parking position.

• Registration, model and full tyre size.
