One problem related to tire bubble has been reported for the 2017 Infiniti Q50. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2017 Infiniti Q50 based on all problems reported for the 2017 Q50.
Dunlop sp sport 5000 dsst p245/40rf19 developed sidewall bubble spontaneously. These tires were standard when the car was purchased new. I have seen numerous reports of similar complaints of sidewall bubbles following pothole encounters. Tires had only 17,500 miles on them. The fact that there are so many similar complaints leads me to believe there is a manufacturing issue.
