BEFORE YOU COMPARE
Run-flat vs normal tyres: replacement checks
Run-flat construction is a specification to verify before buying. A tyre of the same size and model family may use different construction.
What does run-flat mean?
Run-flat technology can provide limited mobility following a loss of pressure. The permitted distance, speed and conditions depend on the tyre and vehicle; use their instructions rather than a universal mileage figure.
Bridgestone’s DriveGuard guidance specifies a tyre-pressure monitoring system (TPMS) for compatible vehicles. That product-specific statement does not establish that every run-flat tyre fits every car. Bridgestone DriveGuard information ↗.
Before replacing or changing construction
- Check the applicable vehicle manual, wheel requirements and TPMS arrangement.
- Identify the exact construction and manufacturer markings on the existing and proposed tyres.
- Ask the vehicle manufacturer or qualified fitter to confirm a change of construction, including any mobility or spare-wheel arrangements.
- Then compare the same size, load and speed requirements and the full fitted cost.
Comfort and other characteristics can differ between constructions and exact products. They cannot be ranked from the run-flat label alone. Bridgestone’s tyre-type overview ↗.
How we handle construction in this catalogue
The supplier sometimes records run-flat terms such as SSR, ROF or ZP in the product name. A missing marker is not proof of conventional construction. Read the exact retailer specification before purchase.
Our AllSeasonContact 2 range page keeps the separately named SSR model out of its main selection. Car references preserve the scope of their manufacturer sources; neither a model name nor a size match confirms compatibility.
Find the vehicle specification, then compare tyres in the confirmed size. The retailer links and observed price history appear on each exact-variant page.
