Malky P.

I suppose these tyres should be good as Mini chose to fit them in the first place.

I have only interacted with them in bad weather conditions, so I am looking forward to seeing how they perform in good weather.

Michelin Pilot Sport 4 S

All I can say about the PS4s is positive feedback and they are the only tyres I will run on my M3.

5/5

Brilliant tyre. Provides excellent grip in wet and dry conditions. The performance was outstanding during a thousand-mile drive around Wales right after fitting and on a track day at Snetterton a couple of weeks later.

Goodyear Eagle F1 (Asymmetric 5)

Fantastic across all conditions.

245/30 R21 is a low profile tyre used on high performance saloons and SUVs with 21-inch wheels. It has a width of 245mm. Because the number is 30, the section height is 30% of 245mm, so the sidewall height is 74mm. R21 means the tyre is of radial construction and fits a 21-inch rim. This gives the tyre an overall diameter of 680mm. Since the sidewall height is 74mm, the sidewall flexes less when turning. Tyres.co.uk stocks this size including the XL versions.
