Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
How do I find the right tyres for a Radical SR3?
Start with the size printed on your existing tyre sidewall — for example 205/55 R16 91V — and use it as your baseline for the Radical SR3. Match width, profile, rim size, load index and speed rating before considering brand or pattern.
What's the difference between summer and winter tyres for a Radical SR3?
Winter tyres use a different rubber compound that stays flexible below 7°C, plus deeper sipes for snow and slush grip. For UK Radical SR3 drivers in colder regions, dedicated winters or 3PMSF all-seasons can be worthwhile.
Does the EU tyre label help when choosing tyres for a Radical SR3?
Yes — the EU tyre label rates wet grip, fuel efficiency and external noise. For the Radical SR3, prioritise wet grip first (UK weather), fuel/range efficiency second.
What pressure should the Radical SR3 run?
The correct pressure for your Radical SR3 is on the placard inside the driver's door frame and in the handbook — not on the tyre itself. Pressure varies by load and trim. Check cold once a month.
What's the legal tread depth for a Radical SR3 in the UK?
The UK legal minimum tread depth is 1.6mm across the central three-quarters of the tyre. Many tyre safety bodies recommend replacing at 3mm for better wet weather safety on the Radical SR3.
