The tyres are doing good and look good.

5/5

These tyres are amazing! My previous ones were also great, the original Goodyear ones from Jaguar. I thought switching to Michelin was going to be rough since I would be leaving standard fit but I couldn't be happier! Super impressed with these tyres.

5/5

Michelin CrossClimate 2

So far, grip is good in all weather conditions.

2/5

Michelin Primacy 4+

I altered the way my BMW 116d drives. Before, it was dreadful in wet conditions, but now the handling is what you would expect.

5/5

Kustone Passion P9

I've had a smoother ride than before and the responsiveness with these tyres is great.

5/5

Michelin Primacy 4+

These provide a high level of comfort and remarkably silence. They also provide reassurance with excellent grip and braking in all weather conditions. I have yet to make a comment on their durability because I have not used them for long enough.
