I know a lot of riders who get far less miles than I do, and on the same tires I have. Don't know the big difference for it. I am a very conservative rider compared to a lot of riders. I also changed the tire pressure from what the bike manuals recommend since the bike manufacturers are more interested in making the ride more comfortable than having the tires last a long time. I research the tire maker web site for their fitment guides and find the their recommended max pressure for a given tire. I have found, starting with my GW, that the tires will last much longer at the higher pressures with almost none of the weird wear patterns that can happen with under inflated tires... like cupping. Also, I have word from many who use a c/t on the rear only and they have told me of poor tire wear on the front as a result, a change they noticed after adding the c/t (both GW riders and ST1100/ST1300 riders). When I first bought my GW I followed the manual recommendations of 33f/36r psi and those tires didn't last even 10,000 miles. After some research and also advise from other GW owners I bumped the pressure up near the max and put 40f/41r and that set of tires went over 21,000 miles (Dunlop tires) with no cupping or any wear issues. I've done this since on all my bike tires. Read the fitment guides from the tire makers and go with that pressure, maybe a very little under for the front... maybe. The ride was not significantly worse for it, though I could tell it wasn't as soft. But the tires actually seemed to grip better, especially in rain. Not so much floating from too much rubber down (I am guessing). Currently I am keeping my CTX1300 tires at 39f/42r psi. Another issue I am aware of is the road surfaces that can have a major effect on tire wear. Concrete wears a tire less than asphalt, which can really tear up a tire. We have a lot of concrete roads around my area. Don't know what else may be a factor. Just know I've been able to see longer tire wear than most riders of any bike I've owned since the GW. Even my Burgman would get over 12,000 miles when others of that scooter were only going 6,000-7,000 miles riding on the same tires. I can already tell the stock tires are not a good as what I had on my ST so we'll see how many miles I go with these. I am hoping there will be more choices when the time comes. Maybe switch my Dunlops for Bridgestones next time. :350x700px-LL-66dd6d
