Find Tyres for 2015-2020 Mercedes-Benz S-Class (A217)

Frequently asked questions

Quick answers about UK tyre fitment, MOT rules and seasonal options.

• What tyre size does the 2015-2020 Mercedes-Benz S-Class use?

  Common UK factory fitments for the 2015-2020 Mercedes-Benz S-Class include 255/45 R19, 255/40 R20. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.

• 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.

• What wet grip should I look for on the Mercedes-Benz S-Class?

  For UK driving conditions, prioritise an EU tyre label wet-grip rating of A or B. Wet grip directly affects braking distance — the gap between A and E ratings can be more than a car length at 50 mph.

• What does the chassis code A217 mean for tyre choice?

  The A217 chassis code identifies this specific generation of the Mercedes-Benz S-Class. Tyre fitment guides and parts catalogues use the chassis code to match correct sizes, load indices and speed ratings — useful when ordering online.

• The S-Class uses 19" or larger wheels — what should I know?

  Larger wheels mean lower-profile tyres with shorter sidewalls — that means firmer ride, more pothole sensitivity and shorter tyre life on UK roads. Premium tyres usually repay the extra cost on cars with 19"+ wheels.
