Happy with ride and noise level. My only concern is that Run Flat P7 tires last between 30,000 and 35,000 miles compared to some regular tires which wear out longer. They mount on the 2017 BMW X3 and replace the factory P7 tires. BMW charged me $1,300 plus wheel alignment (I tried not to laugh). The local tire shop quoted $264 per tire plus taxes, fitting, etc. Revain saved me quite a bit ($200+) and the trucker was out of state so I saved sales tax as well. The tires aren't noisy and don't ride erratically like some would expect from a flat tire. I have tires of the same model on my Acura TL but not the Run Flat version, they are also quiet and handle quite well. I had Michelin tires which I liked but their run flat option was very expensive. Overall I am happy with the P7 and would order it again.
