Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
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.
What wet grip should I look for on the smart forfour?
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.
Are run-flat tyres needed on the 2004-2006 smart forfour?
Most 2004-2006 smart forfour cars were supplied with conventional tyres and a spare or repair kit. Only fit run-flats if your specific car was originally specified with them and has tyre pressure monitoring.
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.
How long should tyres last on the 2004-2006 smart forfour?
Typical UK tread life on the smart forfour is around 20,000-40,000 miles depending on tyre brand, road conditions and driving style. Heavier trims tend to wear faster.
