I put 19.5 Samsons on my rig in 2012. They have a little stiffer ride than the Goodyears, but sidewalls and overall tire are heavier duty. In 2012 I had a local tire shop put 6 on for approximately $1100.00 out the door. This summer, I drove around the forgotten coast of Florida, then south along the gulf coast of Florida, Keys, back up through the space coast, Orlando and back home to Pensacola Florida. Last week drove over a thousand miles round trip to Ashville, North Carolina. My coach is governed at 75. I keep it pegged out on the interstates. I sing SG music and traveled with a pro-group that put in upwards of 100,000 miles per year on their Prevost. I slept in my bunk while rolling down the road on Samsons. Now there are some on this site that are die hard Michelin people. That is fine, if you have money to burn. I don't, so cheaper is better for me. The ride....well, it does not make that big of a difference to me. Oh....most of your camper dealers like CW will charge much more for a set of tires. Try calling some of the local, well known tire dealers around town and see if they can install them for you, before going to the Camper dealers.
