Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
Are all-season tyres suitable for the Radical SR3?
All-season tyres carrying the 3PMSF snowflake symbol are a sensible choice for UK Radical SR3 drivers who don't want to swap between summer and winter sets. Confirm the size and load rating match your OEM spec.
What speed rating is required for the 2001-present Radical SR3?
Performance variants of the Radical SR3 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.
What should Radical SR3 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.
How long should tyres last on the 2001-present Radical SR3?
Typical UK tread life on the Radical SR3 is around 20,000-40,000 miles depending on tyre brand, road conditions and driving style. Heavier performance variants tend to wear faster.
Why does the same SR3 generation list multiple tyre sizes?
Within one generation of the SR3, Radical offered different wheel sizes by trim and option pack. A Sport or M Sport variant might use wider, lower-profile tyres than the entry trim. Always go by the actual wheel fitted to your car.
