Something to consider: Investigation Reveals Goodyear’s Dunlop D402 Tires Have Caused Dozens of Motorcycle Accidents (https://www.legalreader.com/investigation-goodyear-dunlop-d402-motorcycle-accidents/)
-
I've used quite a few of them (D402) over the years, even at speeds well over 100 mph, on lite and heavy bikes, and never had a problem.

Joan Cranbrook has never been an NHTSA Administrator, no matter how many times the author of that article writes it. He might want to expend a tiny bit of effort getting the facts right. I'll even give him a hint; try looking up Joan Claybrook.
Out of the hundreds of thousands (probably millions by now) of D402 tires produced, 5 deaths and 22 injuries supposedly caused by a failure of those tires is hardly cause to run out and rip those tires (if you have them) off your bike. Consider the source of the article (ambulance chaser comes to mind).

i felt that there was also some sensationalization going on there myself. while 'technically' correct, i would not equate 27 to 'dozens'. dozens to me conjures up oh, 50 or 60 at least.
while i have my reasons for not using dunlop, with the millions of them sold as oem, and replacements, if there was an issue, i would think that we would see more. they even allude to it in the article, 'rider error, ie under inflation, etc'.

I've been using stock OEM tires every since I started riding CVOs in early 04. I've been over 100 mph on each of them, more times than I could ever remember.....even loaded riding very long distances in the summer.....even pulling the Bushtec. Never a problem with tires with one exception.
On my 10 CVO Street Glide I had a front tire that wore very fast, on the left only! I took it to Sacramento Harley Davidson and they tried to tell me it was because they're building the crown in the roads much higher (last time I took it to a dealership). Never did find out what the deal was with that tire. From the center of the tire to left bald.....from the center to the right edge still looked new.

When you replaced the tire did the replacement tire wear funny as well?

Thanks Jerry. I can remember that far back, to the utter disaster the Carter administration was. Claybrook was/is a nut.

Lots and lots of those tires out there on the road. They were standard equipment for many year. I have rode all over the country on those tires, in temps from 20 degrees to 107 degrees and high speeds, and loaded bagger. Never had an issue.
Wonder how many were several year old tires like five or six years? Wonder how many were not properly inflated?

JCZ, didn't the dealership explain that you were riding more left hand curves & needed to turn around & go back thru to get even tire wear. Or you could just turn the tire around. :2vrolijk_21: :orange:

The way I heard it was he got stuck in a roundabout, constantly riding in a left hand turn. :nixweiss:

That's why back tires wear worse going uphill (and front tires wear worse going back down)?

Does the bike leaning left on the jiffy stand make flat spots on the left side of each tire? :nixweiss:

Only if the BSR is a big girl.

BSR size here is just right. If you say differently I do not know you, never met you.
Figure the tire air is fresher the closer you get to the valve stem. Stale air is on the opposite end. This has nothing to do with the topic but figured we never had a post on this & here is as good a place as any to have one.

Somewhere somewhen someone (probably you or me) has taken a nitrogen thread and turned it toward stale air. Ain't no way it hasn't happened :huepfenlol2: .

Agree & indubitably because the internet has everything. :huepfenlol2:
I miss the old days, when we got great internet tire facts like if you ride a German bike the tires need German air, Italian bike - Italian air, American bike - air from country your tires are manufactured in. Chinese bike tire air is by now under quarantine conditions because, well, you know.... :huepfenjump3:
Am changing out the winter air in my tires for spring air this week. :2vrolijk_21:
-
Thanks for the reminder. I do the air change when I change the clocks.

It costs a little extra but I get the multi-viscosity air so don't have to deal with seasonal changes.
-
I'm liking the sound of that. Annual vs semi-annual changes would save me a lot of both time and money. Would make sense to do it when it's on the lift for the muffler bearings (the updated sealed bearings). :2vrolijk_21:

I used to do the same, but noticed the tire was wearing out from the inside at a much faster rate due to the viscous friction in the warmer months when the Florida air gets very humid and internal tire air quality plummets due to excessive Global Warmings. You are lucky to live in Missouri, your MO air does not cause this type of problem.

Those are a much better option and metric muffler bearings can last up to 2.34% longer than the English version.

Florida air is lumpy :huepfenlol2: .
It's the only place I've ever ridden where the air is as hard as the bugs that are in it.

True. Lumpy and bumpy air in the swampy bug infested jungles of Florida. Lately the widespread outbreak of coronavirusweareallgonnadiebuyallthetoiletpaperyoucanfind plus our usual frenzied panics have increased the viral viscosity of our lumpy air to where some bugs just sit on it and do not need to use their wings to hover. :o
The Dunlop D402 tires seem to be especially prone to lumpy air issues. Am having trouble finding a social network lawyer to discuss internet type litigations because most of the social network lawyers have decided to become social network infectious disease Drs. and viral outbreak specialists. ::)
