If you live near a Discount Tire -
Take your less-than-one-month-old RV, TV, trailer (or buy new tires there) and get the road hazard warranty. Discount tire will warranty any tire they didn't sell as long as you bring in the veehicle soon after purchase.
Included in the warranty is free tire rotation.
I am horrible with tires. Once owned a tire for 6 hours before ripping a huge hole in the side. Took my demo trailer in one day. They saw the dry rot and sold me 5 new tires, installed, for $45.
The downsides - they aren't open on Sunday and are generally only in the south.
