305/40 R20 Tyres

305/40 R20 tyres are often found on large SUVs and luxury SUVs like the BMW X5 and Porsche Cayenne.

With a 305 mm tread width, a 40% profile, these tyres are made for 20-inch wheels. If you'd like to learn how to check your tyre size, our guide shows you how to do this based on the labels on your current tyres.

Our Price Match Promise ensures that you won't find these tyres cheaper anywhere else in the UK. Once you're happy with your tyre selection, check the available timeslots for local garage or mobile tyre fitting - simply choose whatever works best for you.

Our range of 305/40 R20 tyres includes cutting edge technology from the likes of Goodyear, Continental and Dunlop.
