Michelin Pilot Sport A/S 3

Excellent service from beginning to end. I am very pleased with how fast everything was. Would highly recommend.

4/5

I was looking forward to these tyres, and they haven't disappointed me. While driving on the motorway, they feel solid and give confidence. They have been tried in both the rain and the shine, and although I've experienced a bit of road noise, they have done the job. I think for what I have paid, I could of got a better deal, but I am still content.

4/5

Michelin Pilot Sport A/S 3

Good tread life considering the price.

The Porsche Cayenne fits the 305/40 R20 at the rear. We offer this size with the XL designation at Tyres.co.uk. XL means extra load, and the 305mm width, 40% aspect ratio and R20 designation give the volume needed to support it. On a 20-inch rim that works out at a 122mm sidewall and a 752mm overall diameter.

Part of the size	Value	What it means
Section width	305	The width of the tyre across the tread, measured in millimetres.
Profile (aspect ratio)	40	Sidewall height as a percentage of the width - here, 40% of 305 mm (about 122 mm).
Construction	R	Radial construction, which is what nearly all road tyres use.
Rim diameter	20	The wheel diameter the tyre fits, measured in inches.
