Provides a more comfortable ride, better grip on the road, and is significantly quieter.

I've been able to use them very little due to the current situation.

Top of the range quality tyres on a top of the range vehicle. Tyres are not an area to make savings. The car we bought had one odd tyre, so being a quattro, I replaced all four.

5/5

Goodyear Eagle F1 (Asymmetric 2)

I typically put Pirelli P0s on my Porsche Cayman, but they can be difficult to find. So, I went with the Goodyear Eagle F1 Asymmetric 2 instead. The difference is incredible, the ride is a lot quieter and more pleasant, and there is far less of the Ackerman effect (that cold fully steer judder) with the P0s compared to these. I highly recommend them.

5/5

Bridgestone Alenza 001

I always love these tyres, they do the trick every time I buy them and I will most likely buy them on the internet next time.

285/40 R21 Width, Profile and Rim

285/40 R21 is an SUV tyre size that is specific to the front of the Porsche Cayenne. The numbers indicate that the tyre is 285 millimetres wide. The 40 is the sidewall height to width ratio as a percentage, so the 40% of 285mm is 114mm. R21 indicates a radial tyre that is mounted on a 21-inch wheel. This combination gives a diameter of 761mm. The 114mm sidewall height is suitable for the weight of the Cayenne, and the tyre is expected to be an XL (Extra Load). Tyres.co.uk sells 285/40 R21, and the XL version as well.
