Drop in Dunlop K555 mileage
Written by Leland Sheppard on 10/31/2012 at 12:00 am

Hi Coasters,

I think my mechanic figured out why more than one of us has experienced
a large drop in mileage on Dunlop K555s: They are no longer made inJapan.

My current set of tires says 'Made in Indonesia'. The set on my '94
still says 'Made in Japan'. I would bet that my prior set of K555s on
my '89 and '90 also said made in Japan... The tires on both bikes will
be gone at about the 7,000 mile mark versus around 11,600 on the prior sets.

I wrote to Dunlop about the mileage drop but I asked if they had changed
the compound; they said no.

I'm going to write them again and suggest that unless the situation
improves dramatically and quickly that they are going to lose a bunch of
customers for that tire...

A 40% drop in tire mileage is terribleand indicates a major problem of
some kind...

This reminds me of the situation with Metzelers: Until the tires were
made in Brazil, I don't ever remember hearing about chunks of tread
dropping out of a tire...

    My last set went to about 7000 miles.  I think the ones on it now will probably do about the same.  I had heard they were capable of 10,000.

    I wonder if the person you talked to really knew what he was talking about. If the compound is the same it certainly doesn't make any difference where it is made. My son tells me there has been a lot of discussion about this on ADV rider and the

    There is likely more to the story. What I have found is when manufacturing is moved to a less industrial country, the quality control on the raw material is much worse. The refinement and processing the raw material is not as pure. Even though it may

    Mine say "MADE IN JAPAN"If it helps, the number in the replaceable slot is NA2M401.  I assume that would tell somebody when exactly they were made.  I couldn't find a date of any kind.I let the shop dispose of the old

    Most welcome.  I just wish I had checked the old tires first.  The final mileage on these may yet surprise me.

    I asked my son where he got the information about tire chemicals being banned. It turns out it was not ADV, but rather a friend who is a engineer that works for a company that makes water jet cutting equipment. Apparently he was working on a project

    Europe has more environmental restrictions than Brazil, so that may be something you are running into. I know European brake pads have a much worse problem with brake dust than American ones due to environmental restricions. Could have been the same

    I replaced my two year old 12,000 mile front Dunlop a couple of months ago. It was made in Japan and still had good rubber left on it. I think it was also the first time that a front tire wasn't scalloped... for me any way.

    When my Metzler chunked, I did some research and found that a batch of Brazilian Metzlers had been recalled. I'm hoping all that is past. I did report the tire to Metzler. (It's been a few years.)
