We just bought a 2012 Keystone Cougar XLite 26SAB (6900#). The original owner, a US Air Force veteran who took immaculate care of the rig, has the original tires on the rig and told me they only have about 7,000 miles on them from one cross country trip. I haven't looked at them closely let, but we're going to put about 1,000 - 1,200 miles on them at the end of July and I'm wondering if I need to spend the money now for new tires or wait until our first full season next spring.
Any thoughts are appreciated and I'll update this post once I've closely inspected the tires and found out their manufacturing location.
