Here's another interesting tire from Cooper. It has the same great ride, & handling specs as the Cooper CS-4 touring tire, with a 70k mile warrantee, but is available in more sizes. The Cooper Discoverer CTS!
I was thinking of getting them for the Sportage, but I found them too late, I had already just bought the Cooper CS-4's in the stock EX size 235/55/18" as I stated in another thread posted here.
They're available in a 235/60/18" making the speedometer a bit more accurate, & allowing a bit more ground clearance. They might even be cheaper then the CS-4's?
There are many rave reviews right here for this tire.
