    Although, felt couple times the handlebar was slightly wobbling ?!?
    Maybe the quick turn-in is a Shinko brand characteristic. I found that a new Shinko Raven street tire does the same thing and takes 500 miles of riding to get accustomed to or for the tire to return to “normal”. The only handling quirk I noticed with the 705 is that they squirm around on tar snakes, sort of like the feeling of riding a metal grate bridge.

    Oh yes, they do not like Tar Snakes and neither did my Conti-Motions. I nearly dumped the NC wearing Conti's on a section of Tar Snakes coming down the Lewiston grade and almost took the scenic route haha! :{)

    Right, lets break it down further.
    I measured the sidewall height on my slightly squared Pilot road 4's 160/60's, unsure of mileage, looks like they could last another 1.5k. From the apex of the tread with a square, caliper, and my eye I measure the total height from bead as 90mm. The tires brand new spec is 96mm. 90mm is 93% of original. Does this mean the speedo would show 7% faster speed...

    Attachment 38945

    60mph x .07 = 4.2mph add difference 64.2/60 = 107% speedo reading
    A 150/70 brand new is 105mm tall that's 9% taller than a 160/60
    60mph x .09 = 5.4mph subtract difference 54.6/60 = 91% of actual speedo reading

    How many miles or milimeters till a 150/70 will read true speed? also speedos are not very accurate anyways

    The problem is that the math is exact but the tires are not. I've learned only use the numbers for a rough estimate.
    The actual size of tires varies according to manufacturer and style/profile. And mileage, inflation, weight of bike etc.

    At some point I mount my Garmin to the bike/car and compare my speedo (at different speeds) to that.

    Compared to Metzeler Z8s in OEM sizes, based on mfgr published data, the 705 front in 120/70 is a 4% increase and the 150/70 rear is a 7% increase in rolling circumference. Since NC uses rpm and gear to calculate speed based upon stock final drive ratio, you will be reading 7% low on speedo with just the tire change.

    I use the gearing commander for tire/sprocket changes, It it pretty accurate. Like you mentioned, i never really cared anyway as i always use my Garmin Montana or GPS on my phone for accurate speed measurement. With my 17T/39T and 140/80-17", my speedo is running almost exactly 19.5% slow. SO, with that in mind, now you know. :{P

    Ran across this in my research for cruiser tires for my Nomad. Dang Shinkos! No way, Jose!

    A Shinko 777 looks like the picture below, according to the Shinko web site.

    A little credibility is being lost in that message, because a 777 tire is not what I’m seeing in that photo in post#37. It looks more like a 705. Plus, there’s a lot of info missing surrounding the incident, like proper sizing, application, tire pressures, etc. Having used three different Shinko tire models myself in various applications with no trouble whatsoever, I’m not scared.

    I should have clarified. Shinko 777 was what the thread topic was initially based around, as the OP was complaining of very poor tire wear out of a supposed long lasting model (777) on his Harley. Like half shot rear tire in a matter of a few months. Then another guy posted the pic of the 705 as a reference to Shinko's quality, or lack thereof. Which is why I posted it in the 705 thread here. Figured as hot of a tire as the 705 is here, there would be some interest in a pic of one with tread lugs blown off of it. Bet that made for a bumpy/scary ride from 70mph to a stop. Lol

    I had a Continental Vanco2 tire detread off my motorhome at speed. Scary. I went and got new Continental Vanco2 tires. Stuff happens; a singular incident is meaningless when the internet isnít full of such reportsóas it would be if Continental tires sucked.

    Iím not at all deterred from buying Shinko tires by that anecdote & photo.
