well i just ran thru my 1st set of Kumhos. i put them on the rear 30K miles ago and they are gone completely. i looked for a tire that has a linger mileage and found the continental extremetraction dws. the reviews are good and the price is right - problem is the 255/35-19 is on national backorder until end of july so ordering now will get you on the list for ~ end of august. that tire has a utog of 580 and very positive reviews. sorry to say i cannot wait that long to get them so i went with the michelin pilot sport a/s plus. they have a utog of 500. i know these utog numbers are not universal but i'm hoping they represent treadlife at least within the manufacture and the other michelin's are in the 280 range so i'm hoping for 40-60K miles. anybody using these tires and if so how are they holding up?
