Shinko 170/80-15

I finally mounted the Shinko Tourmaster 230 tire on Saturday, and have ridden 200 miles, 1/2 of it 2-up. Here's my thoughts versus the ME-880 I removed:

1. From memory, the Shinko has one fewer ply than the ME-880, and seems to ride a little softer since the carcass isn't as rigid.
2. The Shinko is lighter than the Metz and is perfectly round with no molding mismatch
3. Shinko was slightly easier to mount and seat than the Metz.
4. Shinko required ~2 ounces to balance, the Metz required ~1.5. There is no observable vibration. This was a bit disappointing, but the tire rides fine.
5. RPM dropped 3% with the Shinko vs. the worn-out Metz.
6. At 41 psi (the max on the sidewall), the Shinko was harsh, but feels OK at38psi
7. Of course the bike handles better and is more responsive-- it has a new tire on it with a round cross-section-- I'm not sure I could fairly compare the handling or ride since the Metz was totally worn out, but I can say that the Shinko rear does well with grooved, cement pavement. The bike doesn't wallow as much on higher speed corners, but how much of this is simply because the tire is new, I can't say.
8. I got almost 20,000 miles out of the Metz, we'll see how the Shinko does...

Overall, a thumbs up so far. I'll mount the front in a week or two.

I'm riding on the Shinko's as well. I have NO complaints. Like the tire very well.

1500 mile rambling update for rear Shinko 230: Still a big thumbs up- no abnormal signs of wear. The 230 is definitely more sticky than the Metz both wet and dry, so in that respect, I would say, safer. I haven't hit any hard rain, so can't comment on hydroplaning. Tire is around 34 psi now. With my gear and backpack, I weigh about 215 or so. Handling is not as good as it was at 38, and it is not noticeably more "cushy", so at my weight, riding style and preference, the sweet spot for pressure is around 36-38 psi. The reduced unsprung weight of the Shinko 230 vs ME-880 is definitely noticeable. I usually only put air in every month or so, but I check it more often. It's a funny thing that people who ride every day tend to be less careful about pre-ride inspections, but I ride enough that I can tell if there is a pressure issue before I get out of my neighborhood. I try to give the bike a once over on the weekend- last weekend I found the rear engine mount thru-bolt half unscrewed!

3,200 mile upate: .175" tread depth remaining. That's about 5.5/32"

I didn't measure tread depth when new- does anybody have one they can measure? I figure I may not get 10,000 miles, when I can get about 19,000 out of the 880.

If I don't get 10,000 miles at the wear bars, I just may go to the darkside.
