A little input from a previous wholesale tire salesman . Cooper tires typically wear very good , but have a tendency to be out of round . best thing to check is that the tire has not ben trued . you can see this on a new tire on the outside ribs it will look like its ben shaved in spots . I sold tens of thousands of cooper tires in the years I was a salesman on the road . After leaving the Cooper distributor , I sold almost every other major oem tire manufacturer out there , so this is not a jab against cooper tires in anyway
im on my 4th set of cooper tires. between thier cobra GT and ATR
never found and out of round tire as you mention...
as for were traits... i agree
