if you choose not to go dark side then give Avon tires a try. When I sold my CTX I already had over 7600 miles on them and still had more than half the life left on the tread. My first set of stock Dunlops lasted more than 15,500 miles. Yes, on the CTX1300. But the stock Dunlops were terrible tires and slipped all over on anything but bare dry concrete. Even then, I still had tread left on both tires but swapped them due to getting close on wear and had a thin construction spike in the rear causing a very slow leak.
I only rode just over 8500 miles on the Shinko tires I put on after the Dunlops came off. Then I returned to the Bridgestone Exedra Max tires and put just over 9000 miles on those. Still looking for better lasting tires with good grip and remembered trying Avon tires on my ST1100 that seemed to last so put those on next. Besides, when I put the Avon tires on the CTX there was a 15K mile guarantee on Avon tires. They did look like they would make it there when I sold the bike.
I was used to putting over 21,000 miles on my Gold Wing tires using Dunlop Elite II but those aren't available any more or for this bike. Did those miles twice on the GW. My first Burgman 650 I had Bridgestone tires and put over 12,000 miles on those as well. Figured lower miles due to smaller diameter but with the ST I really didn't do better until the Avons. My current Burgman 650 needed new tires at just over 6000 miles so replace the stock brand/model tires with Shinko. I don't know what is going on with that. Other than possibly tires are just more cheaply made these days. Figure for the half price cost of Shinko tires it won't be a big deal if I only get another 6000 miles from them.
Longer than 5000 miles should be easy on this bike depending on tire choice and riding style. Keeping psi at the Honda recommended pressure for the front will wear that one out rather fast so I did as I learned on my GW... kept the front at 39-40 and the rear at the recommended 42 psi. Tires may be slightly harder (never noticed really) but won't develop cupping and will last longer than lower psi. Since my GW I never follow the psi recommendation but rather what is on the sidewall or in the tire fitment guide from the tire maker.
I ride all my bikes like I rode that Gold Wing. Like a touring bike. I just prefer a more relaxed conservative ride. Road surfaces also play a big part. Chip and Seal roads will eat mc tires for breakfast. Around here we have mostly concrete roads so tires do tend to last a bit longer on that surface. You would think smooth asphalt roads would be nicer to tires but not so (way better than Chip and Seal roads but not as good as concrete). Riding style will also effect wear. Sporty riding will wear the rubber off faster, conservative touring-like riding is much less wearing. Oh, also Bias Ply tires will last longer than Radials, but the CTX is designed with Radials in mind so choose wisely and YMMV.
Just thought I'd mention that riding longer miles on mc tires is possible.
