I purchased my 2018 audi sq5 brand new from the dealership in april 2018. i believe the pirelli tires that were put on the car during producation are defective. the inside of the tires came apart; the noise cancellation pads came apart in the tire and have rolled up. they were causing the whole car to shake when i would go over 50+ mph. these were unsafe tires to be driving on. i am reporting this to you incase you have not heard about the defect in these tires yet. they are unsafe tires to have on the road. the dot number on these pz4 tires: un rm v376 4517. i had to replace these tires at my expense. i feel these tires are horribly unsafe and need to be recalled. https://vidmails.com/v/wyatda44dt
