Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
Where should I check the original tyre size for my smart forfour?
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 should smart forfour 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 tyre size does the 2014-2021 smart forfour use?
Common UK factory fitments for the 2014-2021 smart forfour include 165/65 R15, 185/55 R16, 185/50 R17. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.
Are budget tyres OK on a smart forfour?
On lower-power, lighter cars like the smart forfour, mid-range tyres often deliver the best value — premium isn't always justified. Avoid the cheapest unbranded options; check the EU tyre label before fitting.
Is the smart forfour still on sale in the UK?
As of the 2014-2021 window, the smart forfour was on sale in the UK during this period. Tyre fitments listed here reflect UK-market specifications.
