Tires !!!!!!

[Grumpy Goat]

Yours is the first report I have seen about poor wear and cupping with the Roadsmart IV tires. Not saying it is not possible of course, but your riding use case must differ from the rest of us who have had good results with these tires. I do have a few questions though:

1. What do you mean you are "... told this front tire is badly worn with cupping issue too"? Who is telling you this and are they trying to sell you tires? Can you not check them for yourself and maybe post pictures here?
   
2. If they are wearing out at 14k miles (8750 miles) then that is within normal range for a sport bike, depending on the road surfaces you are riding and the loading on the bike (combined 2-up load of 260# noted). "Good" roads don't necessarily shed any light on the aggregate surface quality, and whether it will act as a cheese grater on your tires. I have never heard any RS owner getting 30k on the rear and 50k on the front, even in kilometres.
   
3. What is a "Yamaha 1300"? The FJR 1300, which is a sport tourer?
   
4. I note the Dunlop Elite 4 Tires are primarily cruiser tires. Could be their compound is harder than the Roadsmart IV.
   
5. Yes, you can mix and match tires especially is you are not riding aggressively.
