He all, just put on a set of Michelin Commander 2 on my 2010 CVO Ultra. ( stock rims ) Last tires were stock Dunlop's
What I am finding is allot of instability in the front end. The bike shimmies all over the road, Feels like the front end is skating around on ice. When I accelerate to 100 110 MPH the bike starts to oscillate left to right, like a slow speed wobble. Bike was stable as a rock with the Dunlop's . I tried several different tire pressures, and now have 36 psi ( no diff ) Bearings are good, and the tire rotation is correct. Any ideas? Kind of hating these tires right now.
One more thing, the cornering is light years better than the Dunlopes, love leaning the bike over now. Just going straight sucks.
-
May be a alignment problem or may be a tire balance?

I have those tire on my bike and have had no problems.
I actually love these tires and going to put them on my other bike.

You may have a tire that isn't mounted correctly, or just a defective tire. It happens more often than you may think. And even though it feels like the front end is the problem, it can be caused by the rear tire as well. Other than that, make absolutely certain the rear wheel is aligned properly.

I agree!
'Have the CIIs on the '05 SEEG and love them!

Yup, I've had two bad Dunlops over the years - one rear, one front on two different bikes . Got the Michelin Commander IIs now on both my '07 and my '12. No problems at all. Handle great and hope I get better mileage from them with no cupping that I have with the Dunlops.
-
I had Michelin's had the same feeling. Only got 12000 miles out of them. The front tire wore out before the rear one. Switched out to Dunlop American Elite and noticed a big difference in handling and road noise (quieter) on the first ride.
-
I'm having the same issue but I just installed American Elites. But they where balanced with Dyno Beads. I was wanding if this could be the issue. Mine does it around 85 and not all the time.

Dynabeads aren't necessarily a good alternative to a real balance job, and even they admit that if you dig deep enough into the info they post about their product. They may be fine if you have a wheel and tire that don't need much balancing in the first place, but if your tire and wheel aren't quite as good, or you have a lot of runout, they aren't the answer. They don't do a thing for lateral imbalance, or a tire with excessive force variation, or a defective tire with a slipped belt, or a whole lot of other things common to tires and wheels.

There's some antidotal info on Dynabeads in which riders reported their bikes were stable until they reached speeds around 90 mph. This would be in line with what you are experiencing.

It doesn't surprise me that there are issues with the Commander 2's. Put a new set on and only got 7500 miles. They handled well but very disappointed with the milage and yes I routinely check the air pressure. Never again with these tires. Didn't last as advertised, not worth the extra cost.
-
I'm running mich comm II on frt & rear on 08 sg & 2012 cvo ultra. get great mileage on these tires. as of now I have 17k on rear of cvo & have 3.5 - 4/32 tread in the middle. do hear some tire hum as the tires start to wear, but I think you'll find that with any tire as it wears. I may try a set of american elites later on to see if they get better mileage,
-
Awesome tires on my 01 SERG. 36psi on the front tire seems low. I run 40psi front and rear as a single rider. No issues.
-
Rock soild on the '09 CUSE, 40lbs front & rear. Hope & wish that they start making them for the '13 SERK before I can see the air. Have never liked Doneflops.

:oops: You do mean they are not available for 2013 SERK :(
My dunlop are a PIA !
So much cupping than they whines at any angle but 90°
I am to change them (rear at least) next week, for 10.000 maintenance.
If no Commander what do you recommend ?

Which 2013 SERK do you have, the Anniversary or the regular model? The reason I ask is that they come with different wheels and tires. The regular SERK comes with the 19 inch front and 18 inch rear, while the Anniversary version comes with a 17 inch front and 16 inch rear. There are other brands available for the 16 inch rims.
If you have the 18 inch rear rims, there is no acceptable substitute for that 180/55B18 tire. We have beaten that subject to death around here since 2009, and nothing has changed recently. You could always change the rims if you are adamantly opposed to using the D407 Dunflops I guess, but it's liable to be an expensive proposition unless you can find someone willing to pay a good price for your existing rims and tires.

Hi Jerry,
It's an anniversary one.
So I should get the chance for more choice...
What do you think ?
-
French FLHRSE5 Anniversary has D408F tires, front 130/60B19, rear 180/55B18
Can anyone suggest different tires ? Just a dispaired try...

Seems Bridgeston Exedra G850 could fit ?

I wasn't aware the Anniversary bikes shipped overseas were different than the US version when it came to wheels and tires.
Your original tire has an 80 (992 lb) load rating. The Bridgestone you mentioned is a radial designed for lighter weight bikes, and it has a 74 (827 lb) load rating. That is the same situation you will find with other brands that sell 180/55R18 rear tires. None that I've found were designed for heavyweight touring bikes.
Jerry

Jerry,
The load rating difference is equal to passenger weight...
I have none.
Are there any other reason going with Bridgeston would be risky ?

That's a decision only you can make Jean-Jacques. Some people have installed similar tires with a 74 load rating and claim no problems. The fallacy about using those claims to justify doing it yourself is that you are only going to hear from the people who claim they have no problems, if you follow what I'm saying.
The bike, or a car for that matter, is designed with a maximum weight rating that includes passengers, luggage, etc. that is called the GVWR, or gross vehicle weight rating. The tires are then specified to meet or exceed what is required to support that GVWR. In most cases there is a safety margin added because the manufacturers know that many people ignore the GVWR and overload their bikes or cars or trucks. You may say to yourself, well I only weigh 150 pounds and I never carry a passenger or luggage other than a jacket, so I don't need to worry about using the tire specified by the manufacturer. If you're willing to take that chance, it's not up to me or anyone else to tell you that you can't do that. I just point out in these threads what the manufacturer and tire company say is the minimum load rating they recommend. I've also been known to point out that the use of tires rated lower than what's required will also leave the owner of the bike on the hook if something bad does happen. The manufacturer and tire company won't be liable.
Anyhow, like I said, it's a decision I can't make for you. You may find that the tire designed for a lighter sport bike also won't wear as well as the tire designed for a heavyweight touring bike, and it may not be a great match with the stock front tire in terms of cornering grip, etc.. There is a lot involved in specifying tires other than just what will fit in the opening and on the rim. That's why they pay engineers to make those determinations and don't leave it up to just anyone.

I am currently runnin a 180/55 18 Metzeler on the back of my '13 SERK non-Anni with no problems. Never have a BSR as when she turned 70, she said thats it for me. At 68, I refuse to quit and just completed a 8 day 2800+ mile Canadian Rockies ride on that tire. I will stop short of recommending you run that tire because like Jerry said, if I had experienced a problem my death might have prevented me from posting it. Only you know your riding requirements & style.
-
How many miles on your bike? Could be your swing arm bushings.
-
Your help makes me cool, calm collected ! As much as possible...
Some kind of pre-Rushmore effect :huepfenlol2:
I'm going to 10 000 miles visit on Tuesday morning.
Thought of new other tires. You helped me change my mind.
I'll ask they check everything and will go with a brand new collector unique Dunlop : one more year to think about any another choice...

I just ordered my second Commander 2 Rear tire. I got about 13000 out of the rear and got over 18000 on front. No issues at all. Dunlop 402 rear I an lucky to get 8000 miles. Bike tires don't have the deep tread or hardness of automotive tires. Bike tires are lighter for faster acceleration and more flexible for grip in the turns.

'Just noticed that the Commander IIs on the '05 SEEG have 8k on them and still look brand new!!
