How long till my Shinko 705s smooth out?

After tons of tire research on the forum, I replaced the stock trailwings with Shink 705s. They grip and perform well but I hate the vibration! The vibrations from 15 to 45 mph (and when braking) are really bothering me. I was expecting a much smoother ride. These tires vibrate more than the knobbies on my dirt bike!

I have a few weeks and about 300 miles on them now.
When will they smooth out? Will they ever smooth out?

I had one delaminates on me, but they never vibrated. Rebalance them, or maybe you just have an out of round tire, it happens.

They smooth out nicely as soon as they hit the bottom of the dumpster.

My 705s don't vibrate either above 5mph. They do howl at 50mph, however.

My shinko's have never smoothed out.
They are:
Great on gravel roads,
Tons of grip on pavement to scrape pegs.
Perfectly fine in the rain.
Good mileage for the money.

But.......

I will be replacing mine this year. The vibrations are finally getting to me.
Lots of long trips on slab will do that.

Next tire will be Anakee 3 or PR3

bad news, the howl never goes away, it only gets louder.

I've run five Shinko 705's on the rear, and three on the front. The rear isn't that noisy, and they lasted an average of 6500 mi. Out of the five tires I tried one had the delamination problem, so I switched to Shinko 712 for the rear.


The news for the front is.... mixed. Of the three tires all three had good mileage- about 20k. And the front tires had no delamination issues. But all three also exhibited strange behavior as they wore. After about 12k the front tire starts to square off, leaving plenty of tread but strange driving dynamics. The bike starts to resist lean-in, forcing a much stronger response on the handlebars before they start to turn. It's nothing dangerous, but it's quite odd to have the bike fight you in turns.

Even worse, as the front tire begins to square off the road noise increases dramatically until it become a loud howl that is noticeable even through ear plugs. These are the loudest tires I have ever run!


So basically, although I love the price and the look of the 705's, I'm done with them. The 712 has been a good rear so far but unfortunately Shinko doesn't make the right size front tire in the 712 model so I'll have to find something else.

To anyone suggesting rebalance / out of round, etc. that is not the issue.
These tires are brand new and balanced. In fact, the front still has lots of casting nubs on it. They're just not smooth like a 100% street tire would be.

It's those big grooves in the tread design. Every time the tire rolls over the groove, it transfers a vibe up through the bike. Things smooth out after 50mph but at lowers speeds it's very pronounced. My worn out Trailwings were smooth as silk. Did someone mount a sand paddle on here and I didn't notice?

Surely I can't be the first to notice (complain about) this. I'm just wondering if this will go away after I wear them down or do I have to live with it for the next 10K+ miles.

Thanks in advance!

Vibration is very subjective. What gets to some people may not get to others. I knew the tires were going to be vibey. Just looking at the tread design you can see it would generate some noise and vibes.

I've gotten used to it. It's one of the best all around tires I've used so far at a killer price.

In my experience it doesn't get any better over time. But as I said I still run them. It's an adventure bike on a dual sportish tire. It's not going to always be smooth.

I thought it was just me that thought the front felt funny when I first put it on. Takes more effort to get into the turns but stays where I put it. They do have a bumpy stopping effect, must be the tread. If I can get the mileage posted above, I'd be happy.
My Tourance didn't last 6500 miles and the one rear cost more than the set of 705's.
