I had these tires on my 2016 Mazda Miata and had to have them removed when they started losing air. When inspecting the tires for a foreign object in the tread I discovered that the tires were cracked down into the core of the tire all around the circumference grooves. All four tires were totally dry rotted and had to be replaced at a very high cost per tire. My car only has 6200 miles when I saw the tires begin to self destruct. I don't know how long that the tires had been this bad and I just thank God that one or more did not blow out at highway speeds. The Brigestone tire store told me that the problem was premature for the age of the tire but could do nothing for me on the replacement cost of new tires.

I think these are an awesome tire.well worth the higher price
