Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
What does the chassis code W251 mean for tyre choice?
The W251 chassis code identifies this specific generation of the Mercedes-Benz R-Class. Tyre fitment guides and parts catalogues use the chassis code to match correct sizes, load indices and speed ratings — useful when ordering online.
What should Mercedes-Benz R-Class drivers know about UK potholes?
UK road conditions are tough on tyres. Check sidewall bulges, cuts and tread depth regularly — especially on the inside edge, which often wears unevenly. A 20p coin gives a quick legal-tread check.
What's different about the 2006-2014 R-Class compared with other generations?
This is the 2006-2014 generation of the Mercedes-Benz R-Class. Earlier and later generations use different platforms, wheel sizes and tyre fitments, so always match your specific year to the correct generation page.
What do star/OEM markings mean on Mercedes-Benz R-Class tyres?
Mercedes-Benz approves specific tyres for many of its models, marked with a star (BMW), MO (Mercedes), AO (Audi), J (Jaguar) or similar. OEM-marked tyres are tuned for that car's suspension and don't always come from the major brand-name fitter as a stock item — they may need to be ordered.
What wet grip should I look for on the Mercedes-Benz R-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.
