I have 30,000 miles on 275/60r20 tires. They wear evenly, grip the pavement very well in the rain and Boston snow. Living on a hill, hauling a 5km boat and adventurous driving is tough on every tire I buy and I will never get full mileage. After only 5,000 miles the tires start to loosen up a bit in the rain/snow. Although solid for the whole season.
