Michelin 4X4 Diamaris Treadwear Performance

Treadwear Performance Rating



Although the Treadwear performance is fair, it is worth remembering that this is usual in OEM tires. That said, the internal structure features two high-tensile steel belts reinforced by Michelin’s BAZ technology which gives it even wear no matter your driving style.

Michelin 4X4 Diamaris Reviews

While most of the reviews are positive, useful conclusions can also be drawn from negative comments.

Starting with the positive aspects, the vast majority of drivers praise both the striking look of this tire and its ride quality. Considering that almost all drivers are used to the comfort offered by BMW and Mercedes-Benz sedans, this is a great achievement for Michelin.

On the other hand, we note that most of the “less positive” comments have to do with the durability.

According to the data provided by the drivers, it can be concluded that the average useful life of this tire is around 30k miles.

Given that this is an OEM tire and taking into account that almost all drivers admit that they have a spirited driving style, that figure seems quite reasonable to us. In addition, it is worth noting that a small portion of reviewers has managed to extend the life of the tire over 35k miles thanks to timely preventive maintenance.

All in all, this tire fulfills the mission for which it was created to provide a superior driving experience and a level of performance on par with luxury sport SUVs.
