Experinces with Cooper Discoverer STT Pro's

Red Knight15

Caught the Bug
My 37's were bought back when these originally came out back in 2015. I had zero chunking and still had tread left at 50k+ miles. I currently have a set of 40's that are a year old and I have zero chunking with them. (Mind you, these are East Coast Jerry miles, not West Coast Jerry miles). I wonder if there has been a compound change or something that is causing these to chunk. It's really a shame because this tires grip is as good as anything out there. And they wear great.

There maybe a change. One of mine is about 6 months newer and it is the one that chunked up the worst.
