Review of Shinko 712's
« on: May 18, 2015, 06:46:42 PM »
I wanted to pass along my experience with the Shinko 712's. A lot of people ask about them as they are a popular budget alternative for vintage bikes. I just put a set on my K8. My reasoning was that I don't push this bike as hard as my modern bikes and as far as tire performance, they will be superior to anything from that era anyway.

I mounted the front and the tire shop did the rear (because I was getting another set mounted on another bike and only have 1 front stand). My first time out was to meet up with a friend for a ride and the front had a bad wobble. When I got on the highway it was frighteningly bad, so I had to get off and ride slower speeds. I got to his house and notice the light spot mark was a few inches off the valve stem, guess I didn't notice it moved slightly when I was mounting. So we let air out and spin it while still mounted, but that made no difference. So off to the tire guy for a balance. It was off several ounces! He spun the light spot to the opposite side of the valve stem and it balanced and needed no weight. He said he's seen that before even though the rear was opposite. So I mount it back on the bike. Well, the wobble was still there just as bad. So now I take it to the only guy I know who will still true rims an hour away and I have to drop it off! He calls and says the rim was nearly perfect and bearing were good. He tweaked it a little bit but basically the tire was bad. I sent the tire back and got a new one and not taking any chances, took it back to the tire mounting guy this time. He mounted with the light spot at valve stem and it didn't take any weight and this one is fine.

If I would have reviewed them as they are now I would have said they really feel great and were an excellent bargain. But, the reality is, because of quality control issues, I drove to mounting/balancing guy 20 minutes away 2 extra times, drove 4 hours total to rim truing guy, gave him a $20 just for taking the time, paid $35 for 2 balances and 1 mounting that I didn't need, the bike was down for 2 weeks, both guys gave hell for buying cheap tires and I didn't even get to ride with my buddy because we were in his garage screwing with it. Was it a bargain? Not at all. This is the first time I've ever purchased motorcycle tires that were not manufactured in Europe or Japan and I can't imagine I'll ever do that again. Figured I'd pass this along in the interest of helping others make an informed decision.

I used the 230s and my tire guys say he hates to mount them.  He did and good job though and the bike went down the road well.

My experience was different.  I bought a set from Motorcycle Superstore,  mounted and balanced them myself and few weeks later rode from Northern Virginia to Barber and back; loaded for camping.  Me and camping gear means at least 300 pounds payload on the bike.

On the way there I rode the Tail of Dragon, on the way back I was on 81 Interstate for 10+ hours riding in the rain, the whole trip - 1700 miles or so - I could not feel anything wrong with Shinko 712 tires.  They are still on the bike and I still ride it.

Sorry to hear about your bad luck, just my experience is different.

 I've used them a couple of times and never had any problems. A budget choice, for sure, but worked just fine on a couple of 550's.

I used them and never will again...I like to push hard and had several scary slips...I think they warm up slow (or maybe not at all if it is cold out) so may perform ok if you live in warmer climes.  I know, you get what you pay for, but I have run cheapo tires before and it was much easier to find their "limit".  The Shinko 712's really scared me the way they would usually grip but then unexpectedly not.   I had no problems with tracking, balance, or durability...
If it works good, it looks good...
