Milestone Tires Cracking Prematurely—Safety Concern

I purchased Milestone tires, and despite having 70% tread life remaining, they have developed cracks on the sidewalls. At first, only one tire was affected, but now I see the same issue on three of them.

This is extremely frustrating—I shouldn’t have to replace tires so frequently, especially when they still have plenty of usable tread. More importantly, this raises serious safety concerns. Cracks in the sidewalls can lead to tire failure, putting both drivers and passengers at risk.

Milestone, you need to address this quality issue immediately! I expect a replacement or a proper resolution before these tires become a hazard. Has anyone else experienced this? Tire safety should be a top priority!
