Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
Where should I check the original tyre size for my Caterham Seven?
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 Caterham Seven 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.
Are tyres for the 1973-era Caterham Seven still available?
Yes — common sizes for the 1973-present Caterham Seven remain in production from major UK brands. Some classic-specific sizes may need a specialist supplier, especially for limited or sport variants.
What speed rating is required for the 1973-present Caterham Seven?
Performance variants of the Caterham Seven typically require a Y-rated (300 km/h) or W-rated (270 km/h) tyre. Match or exceed the original speed rating shown on your sidewall — fitting a lower-rated tyre can affect handling and may be illegal on certain models.
Are OEM tyres still fitted to new Caterham Seven cars?
New UK Caterham Seven cars leave the factory with original-equipment (OEM) tyres specified by Caterham. When replacing, you can stay on the same OEM brand or move to an alternative provided the size, load index and speed rating match.
