Bought these tires the day I got my 2000 Silverado and 108,000 miles later, they are still going. Am finally in need of replacement, due to age not tread depth. (the tiny cracks in the rubber from 12 years of Sun Exposure make me nervous) These tires are great and have seen it all: Towed a 10K lb trailer for the first 4 years and Deep mud driving while hunting and pretty aggressive off-road/rock handling, to freeway and day-to-day use. Handled a 40-mile commute each day of the week for 8+ years and whatever you could throw at it on weekends! While not as many miles the past few years, the tires are extremely reliable. Highly recommend this tire and am buying another set for my next 100K miles!!!
