My bike had Shinko 705s on it when I bought it. I used them another 15000 km and had no complaints about the wet grip. Mine were the radials. I've heard the bias version had some issues.

I have never experienced cracked tires like that. And I run my pressures low. I have run a knobby Dunlop 739 desert at high speed totally flat for over 50 miles with nothing more than chunked knobs, bead delaminating and melted to the rim.

Last year I ran 32/36 for over 1400 miles on my Super Tenere fully loaded down. The only cracks I got were from sharp volcanic rocks. My Ninja 650R fully loaded with a slow leak ran for hundreds of miles on intermittent low air in the heat of July. When I sopped for the night it was almost all the way flat. Shoved a plug in the tire and finished my trip with no cracks at all.

I have seen lots of stunt riders on bike night that run ultra low pressures both on high speed highway and parking lot stunts (easier to wheelie and do slow speed balance). And still no cracks between the treads.

As a disclaimer I only run high end radial tires on my street bikes and UHD tubes and double rim locks on my desert bikes. I'm pretty sure those Chinko 705 tires are bias ply. And the "Q" speed rating is quite frankly a joke at under 100mph max speed rating. I still believe it to be a defective tire.

That chinko is a Japanese owned company that builds tires in Korea, and own's the molds to Yokohama motorcycle tire division. The 705 comes in both radial and bias ply. Tons of people have run these tires almost as many as the damn E07 and love the bang for buck. Haven't seen an issue like this in a while years actually makes it seem unlikely it was totally the tires fault.

He posted the label from the tire above in post #4 clearly indicating this is a radial tire, and has a speed rating of H. Actually, looking at the Shinko website, there is no bias 150 x17 sized rear 705 available.

My bad, I only saw the Q non radial tires on the website. Still a cheap tire that I would never run on my bike. And yes they do make a non radial rear tire as well.

When you work with the folks from Michelin and Goodyear, they have a common phrase about the top most important three things when it comes to tires. The three are:
inflation
inflation
inflation

Chris, I'm sure that OldRider and I've seen more f-d up tires than you hopefully ever will.

That's fair. I'm lucky that I just have not seen it. Keep in mind that I don't ride tires down to the wear bars. Back when desert racing, one or two races max on a brand new set of tires. On the street I have ran 32/36 on every single bike since the 80's. In the instance of slow leaks I have no idea how low they got. As soon as the bike started to wallow I added air.

Not in an OEM size 705 , at least not anymore according to Shinko's own site.
I was on the wrong website. They do in fact make a bias ply.

Shinko

I still think they are a cut rate rubber for what you get. It's a single hard compound. Unlike a higher quality tire that has 2 different compounds for better traction. It's a case of you get what you pay for.

You still can find the pressure spec sheet if it hasn't faded on some Exploders that still show 29 psi on what would have been Firestone Radials. I've never put less than 35 psi in an Exploder. 29 psi, what were they thinking?

My gosh!! Now I am sure the Shinko is not a tire to get. Just a quick search reveals 100's of 705 failures!! Here is just a small sample of tread separation on this brand:

I’m on my 3rd set of 705’s. My wife has a set on her S10 too. I haven’t had any issue like this. Solid wear, good on the highway, wet or dry. Run well on gravel and light offfroad. Meh in the sand. They suck in the mud, but what doesn’t?

Looks like the bias version might be available in Canada but not in the US, so it appears we are both right.

To be fair I did a search of "Michelin Anakee" tire and found one that had a torn knob. The author was stating "catastrophic failure" from "gentle usage". I almost spit out my water I laughed so hard!! If I had a dollar for every time I tore off a knob I could retire!!

I might add that there is one tire you will be hard pressed to find any failure reports on. The Mitas E07. I know Bob had one fail but his was due to a flat if I remember right.

I like my Stinko's but If I find cracks... I'll hate them.

The bang for the buck is nice. Besides the 705's the Golden Boy's work quite well on the KLR.
