I can't vouch for their longevity. I bought my truck with fresh-looking Discoverer A/T's though. 26k miles (and 12 months) later, they're worn pretty bad and won't make it thru this winter. Last winter they were great, though. I climbed probably a 50-degree incline in the snow with them without a problem! They made a lot of noise around corners after I put bilsteins on. Other than that they've been extremely quiet until they've been at the treadwear marks. For the money I'd definately recommend the A/T's, but go for the light truck version. I think the passenger ones i have contributed to a seemingly short life.
