Find Tyres for 2011-2018 Mercedes-Benz B-Class (W246)

Frequently asked questions

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

• What does the chassis code W246 mean for tyre choice?

  The W246 chassis code identifies this specific generation of the Mercedes-Benz B-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 B-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 wet grip should I look for on the Mercedes-Benz B-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 tyre size does the 2011-2018 Mercedes-Benz B-Class use?

  Common UK factory fitments for the 2011-2018 Mercedes-Benz B-Class include 205/55 R16, 225/45 R17, 225/40 R18. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.

• Can I downsize from larger wheels on my Mercedes-Benz B-Class?

  Some trims of the B-Class can be downsized to a smaller OEM-approved wheel, which often gives better ride and lower tyre cost. Mercedes-Benz usually publishes approved alternative sizes — check the handbook before changing wheel size.
