Santiago Davison

Slight improvement in cornering grip while taking a more aggressive line.

Marnie A.

The tyres work as expected.

Dunlop SP SportMaxx GT

Chace K.

Considering they are run flats, they handle decently, and drive well.

About these reviews

Tyre reviews recording 275/45 R18, across tyre brands and tread ranges. Each review identifies its tyre range.

5/5

Michelin Pilot Sport 4

A recognised brand that provides dependable traction in all weather conditions. Lasts a long time and operates quietly.

5/5

Continental Sport Contact 5

Fantastic performance. These tyres hold the road exceptionally well, even in the rain. I will be buying these tyres again for sure.

5/5

Dunlop SP SportMaxx GT

I am getting the same SP Sports tyres again because I was very satisfied with the performance of the last set.

5/5

Pirelli P Zero

Considering that the SLK isn't the best car in wet conditions, you're doing an okay job. It's for sure not skidding as much.

5/5

Continental Sport Contact 5

I cannot see any differences at the moment.

5/5

Continental Sport Contact 5

Really happy with the performance of these tyres.

4/5

Dunlop SP SportMaxx GT

Acceptable, but not ideal for wet conditions on a rear-wheel drive vehicle.

4/5

Dunlop SP SportMaxx GT

Works well in most weather conditions, including very heavy rain, although due to its width, extreme cases of aquaplaning may occur.

275/45 R18 tyre sizing is for large SUV and performance vehicle fitments. The first section, 275, is the width in mm. 45 is the aspect ratio. Sidewall height is 45% of 275mm which is approximately 124mm. R 18 indicates a radial tyre with a diameter of an 18-inch rim which gives an overall diameter of 705mm. That large sidewall gives extra protection to the rim on poorly maintained roads. We sell 275/45 R18 wide tyres on Tyres.co.uk including the extra load variants.
