Have 2011 Silverado with tow package. I will be towing a Koala 26cc. About 6000# loaded. Had the Goodyear Eagles also. 28000 miles on the tires and looked like they might get 5,000 more. Went ahead replaced the Eagles with the Michelin LTX MS tires. I tow a bass boat and a pontoon boat also. I've had these tires on another vehicle and they are great tires. Quiet ride and great traction. A little pricey, but I kept my old 20" eagles and sold them the next day for $180 bucks.
Will be heading to Montana from Texas soon with the Koala 26cc. Feel very good with the Michelins on the TV.
