5/5

Continental Sport Contact 6

The all-year-round performance of the tyres has been excellent and consistent.

5/5

Michelin Pilot Sport 4 SUV

Fantastic tyres last significantly longer than the Pirelli ones.

5/5

Continental Sport Contact 5 SUV

These tyres are good enough for me. I have not had the chance to drive on ice yet.

3/5

Everything seems to be okay thus far. Steering is indeed responsive and grip feels decent although I haven't had a chance to test it on snow. I may look into all-season tyres for the next ones, but these summer ones are decent enough.

5/5

Bridgestone Alenza Sport

The road grip is first class and I am getting great mileage out if these - highly recommend.

2/5

Bridgestone Alenza Sport

Overall, I am quite displeased with the service because I expected a lot more for the money that I spent.

4/5

Bridgestone Turanza 6

Things are going well and they are mostly being quiet.

Continental Cross Contact LX Sport

Outstanding. Since I bought my car, I have only used one brand of tyres. They handle all conditions.

Continental Sport Contact 5 SUV

Good wear and roadholding.

The ride was comfortable and relaxing, the whole process was very easy, and delivery was surprisingly fast.

Tyres.co.uk stocks 315/40 R21 for your convenience, including the XL versions. 315/40 R21 is the rear tyre size for some Lamborghini Urus packages. 315 is the width in mm. The aspect ratio in this case (40) indicates that sidewall height is 126mm which is 40% of 315mm. R21 indicates a radial tyre that fits a 21-inch rim. With a sidewall of 126mm on a 21-inch rim, this brings the overall diameter to 785mm. Sidewalls of tyres protect the rim from damage by kerbs.
