Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
Are all-season tyres suitable for the Mercedes-Benz S-Class?
All-season tyres carrying the 3PMSF snowflake symbol are a sensible choice for UK Mercedes-Benz S-Class drivers who don't want to swap between summer and winter sets. Confirm the size and load rating match your OEM spec.
How long should tyres last on the 1991-1998 Mercedes-Benz S-Class?
Typical UK tread life on the Mercedes-Benz S-Class is around 20,000-40,000 miles depending on tyre brand, road conditions and driving style. Heavier trims tend to wear faster.
Where should I check the original tyre size for my Mercedes-Benz S-Class?
Look in three places: (1) the sidewall of the existing tyre, (2) the placard inside the driver's door frame, and (3) the vehicle handbook. The driver's door placard is the official OEM specification, and the sidewall confirms what's fitted now.
What's different about the 1991-1998 S-Class compared with other generations?
This is the 1991-1998 generation of the Mercedes-Benz S-Class. Earlier and later generations use different platforms, wheel sizes and tyre fitments, so always match your specific year to the correct generation page.
Did the 1991-1998 Mercedes-Benz S-Class come with run-flat tyres?
Many Mercedes-Benz models in this era were supplied with run-flat tyres from the factory. If your car has tyre pressure monitoring and no spare wheel, replacement tyres should typically also be run-flat. Verify on the existing sidewall — look for "RFT", "ROF", "ZP" or similar markings.
