I would not run tires longer than 5 years. When I got my coach it had new steer tires and six to seven year old rears. I replaced the rears and gave the take off tires to a friend for his dump truck pusher axle. They looked great but lasted less than a month.
I did the 365 upgrade and road king shocks at the same time. It was hard on my wallet but worth it.
I also had a rear anti sway bar added, so I can’t say what made the greatest difference.
