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.

4/5

Dunlop SP SportMaxx GT

Excellent traction on all surfaces and in all conditions.

4/5

Dunlop SP SportMaxx GT

Overall it's great, but the ride is quite firm because they have run-flat tyres.

4/5

Continental Sport Contact 5

Everything is going well, no issues to bring up.

5/5

Dunlop SP SportMaxx GT

Impressive in wet and snowy conditions, even with a rear-wheel-drive Jaguar.

5/5

Dunlop SP SportMaxx GT

The next time I will choose the regular ones instead, as I find these too firm.

5/5

Dunlop SP SportMaxx GT

There has been slight improvement in cornering and fuel consumption.

5/5

Michelin Pilot Sport 4

In my view, the PS4 is the perfect all-round tyre for any weather, so I see no reason to change brands. I have selected them for my last three purchases.

5/5

Dunlop SP SportMaxx GT

They did alright; they coped well in all kinds of weather.

4/5

Dunlop SP SportMaxx GT

Decent tyre for the money. Plenty of grip in the dry and it turns in sharply, though it is noisier than I expected on rougher motorway surfaces.

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.
