Alice Arsh

Yes, I was pleased with everything that took place over the summer. Check back in with me after the winter.

Goodyear Eagle F1 (Asymmetric 2)

Rocco Cahill

As expected, very well.

Michelin Pilot Sport 2

Isla-Mae C.

The tyres are excellent on wet surfaces. They also aren't noisy. They are holding up well against the rough terrain here on the Isle of Skye.

4/5

Kumho Ecsta PS71

They are fine. From an eco-friendly perspective, having 10mm of tread from the beginning would be better.

5/5

Nankang AS-1

Great grip in any weather. The handling is smooth and the noise level compared to my old ones, is a lot less.

5/5

The decrease in tyre noise is most noticeable. This is a direct model-to-model replacement, so I expected them to be pretty much the same, but the new tyres have really made a difference. I've been a bit careful with the car and the tyres so the grip in dry conditions is probably about the same. However, it seems that in wet conditions the grip is greater and the back end feels more stable than it did with the old ones.

5/5

Michelin Pilot Sport 2

They have rim protection, which is a positive feature, and they provide a smooth ride and less noise.

5/5

Michelin Pilot Sport 2

As expected! Good grip and no problems with Tyres.co.uk. I will definitely do business with them again.

5/5

Goodyear Eagle F1 (Asymmetric 2)

The tyres provide noticeably better traction, especially when starting off on wet surfaces.

4/5

Goodyear Eagle F1 (Asymmetric 2)

As I expected, they are reliable, consistent, and have great durability.

265/40 R18 is used on many large performance saloons including staggered wheel set-ups on the Mercedes-Benz S-Class. 265 is the tyre width in mm, and 40 is the ratio. 40% of 265mm equals a sidewall of 106mm. R18 means there is a radial tyre on an 18-inch rim, resulting in an overall diameter of 669mm. The sidewall has less flex on rougher roads. Tyres.co.uk stocks the 265/40 R18 including the XL versions.
