I have done 2600 miles on these tires and everything appears good in every category except tread wear. The front tires are already worn down to 7/32's evenly across the width of the tire and the rear to 9/32 (from 10/32 new). Admittedly it is a front wheel drive car but this unacceptable. I have had the alignment checked by the SAAB dealer recently and it was within specs, the tires are mounted and balanced correctly. At this rate I will be down to 4/32's on the front before the tires need rotating at 5000 miles I am estimating I will only get 7500 miles on a set of 4 tires if I rotate as specified. These numbers I have verified with an accurate tire tread gauge over numerous points on the tire. These tires are rated for 40k miles so I will be testing the Kumho warranty. I have regularly done 40- 50k miles with other car tire combinations so I am at a lose as to what is going on. I have no experience with these tires in the snow as I have only had since April 2012. I will update my review as necessary.
