I guess I'd be the forth one to have a positive experience with the Tow-Max tires that came OE on my 2013 Eagle (built in Oct, 2012). They endured through two trips to & from Texas/Michigan - including a side trip to S. Dakota. Don't know how many miles were on them, but the tread was getting pretty thin on both the passenger side tires when I left Michigan to head south for Texas last fall. I thought I could make it and then replace them once I got there. NOT SO MUCH! Had a blow out while going through Indianapolis on Thanksgiving morning that just shredded the tire. No trailer damage (fortunately), but try to find a tire store open on Thanksgiving! Changed out the spare and made it to a campground about an hour NE of St. Louis. Next day, I called a National Tire & Brake store there, and they had the replacement Tow-Max in stock. When I got there, they advised me that for only $2 more per tire (plus moving up to metal valve stems), I could upgrade a load range. They checked, and the wheels could handle the 80 lbs. tire pressure, so it was kind of a no-brainer. Replaced all 4, but kept the spare. I plan to replace it some time this summer. Really like that I can now drive 70 mph in some places . . . it cut a few hours off the trip back north this spring.
Hope I get another 4 years out of these!
