Has Kumho discontinued their Ecsta MX series? I don't see any news on their site, but Tirerack doesn't show them in their latest print ads and has them listed as backorder on their website. Discount Tires, where I bought my last set doesn't list them anymore either. I've put almost 20K miles on an "oversized" set of 18's on my car, and have had nothing but good experiences with them. I'm about due for a new set of rears, although the fronts have plenty of life left in them. Gary or anyone else know what the status is? I really hope I don't have to switch brand/type of tires again.
