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

The tyres work as expected.

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

Great grip on the road and is quiet.

4/5

Dunlop SP SportMaxx GT

Excellent! They seem to last longer than my previous tyres and do better with the wet roads. I was able to get a really good deal and it was super easy to arrange the fitting online.

5/5

While it's still a little early to make a definite conclusion, they appear to be wearing in more consistently than the Bridgestones which originally came with my car. They also have nice handling and my fuel efficiency has improved a small amount.

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.
