I kept the tyres for a week and had to replace them with Pirelli P Zero’s. The tyres were put on a 4x4 and the rear tyres kept slipping when accelerating. I took the car to BMW and they informed me that the tyres were of such low quality, they didn’t all have a uniform circumference and as such, the tyres slipped and the front and rear axels were out of sync. If allowed to continue, this could have led to damage to the axel, distribution box or both. Lesson learned, buyer beware! Steer well clear and spend the extra money on a known brand!

The tyres are performing okay. The grip is not great but not bad either. Grip in the wet will be testing now that we're entering winter. There's no alloy rim protector that the Continentals have. Price does make up for any shortcomings.

These tyres are great value for run flat tyres. The rear BMW 520 tyres are particularly large and expensive compared to other brands. These tyres are great in both wet and dry and not as noisy as some others.
