I put on a General Altiman RT43 195/55R-16. I know, all the dardsiders swear by the 205/60R-16 but never the less. I tried it for about 150 miles. I wasn't comfortable leaning into a turn and feeling the sidewall flex. Especially from a stand start. Car tires are designed to do that to keep the tread as flat on the road as possible. Exactly the opposite is true for a motorcycle tire. Thats definitely not for me. It made the speedometer show 5 mph faster than actual and odometer register 5% more miles than actual. I know, the diameter of the wheel and tire is a full inch smaller than the stock tire. Also there could be a liability issue. The bike was not designed for that type tire. Insurance being what it is, could or might refuse to pay any liability claim or damage claim if it related to a tire issue, claiming a non-approved modification. I don't want to be the one to test them. Anywho, I put my Commander II back on. 5500 miles on it and it still looks knew. When it was new, it had 10/32" tread. Now after 5500 miles it still has almost 8/32" tread left. Should get decent milage out of it. I probably have a more conservative riding style than most. It's not a sport bike so I don't try to ride it like it is. So, I tried the dark side to see what it was like. Not for me. Back into the light.

Sidewall flex on car tires is normal and will not effect the reliability of the tire unless the pressure is too low. If the pressure is where it should be, there should be minimal flex in the sidewall. As far as contact patch of tread to the road in turns, I have seen many videos of people who went darkside and from what I've seen, the contact patch is as good as motorcycle tires, or better with darkside. And you can't argue with the mileage car tires get. I'm considering going to the darkside when the time comes for a new tire. Only thing holding me back is finding a place that will mount a car tire to a motorcycle rim. As far as insurance goes, they can deny a claim for any reason. They make money by keeping it. Not by paying out claims.

747,, ds is not for everbody and at least you gave it a trial go.. if yor not comfortable, well then don't do it.. its yor ride, dime and life on the line..

buried somewhere in this forum under DarkSide is a video by TallAnnie she shows car tires being squashed deformed under compression on a hi speed dyno. those carcasses can take 1000x more abuse than you will ever dish out on yor sled.

I kept two wheels for my v2k and would swap them out (15min) depending watt kind of riding was todo. long distance was ct, but a month in the benders, I do push the edges, the mt gott the job done.

Now my new heapum big chief Injun (850lb tour bike) came with Dunlop Elite 3 tires.. a special compound for long distance, reports of 18k smiles.. Currently I am at 16k on mine and I swear there is at least another 4k of safely useable tread left on this tire.. If I can get this kind of smileage outa a MT well then thers little push to entertain another CT.. poncho

Thanks for the schooling on tires and insurance. I figured my post on MY experience would bring out the die hard darksiders. A lecture on tires and how wonderful car tires on a motorcycle and insurance both, wow. Contact patch in a turn wasn't a concern. Possible you misunderstood what I was getting at. I tried different pressures and could still feel the flex, and didn't like it. I guess I could have gone to 100 psi but I thought that might be slightly on the high side. I wasn't questioning the reliability of a tire based on the sidewall flex. Not being an expert on tires, but I would think that any tire is subject to failure for whatever reason. I just wanted to try it and didn't like it. I realize others have different opinions, and all swear and be dammed theirs is the right one. And, the tire everyone is running is the best and they get thousands and thousands on miles out of it. I like to try things for myself and see. I remember someone saying "...trust but verify...". O, yeah, it was Ronnie. Since I can mount my own tires just thought I'd give it a try. Like I said, it wasn't for me. I don't hold anything against anyone for running a car tire we all have our own likes and dislikes. I don't doubt you've seen many many videos on people who went darkside. I too have seen some, though maybe not many many, but some none the less. Wonder why so many places won't mount a car tire on a motorcycle rim. Just saying.......

Which is why anyone posts an opinion about the dark side. Don't get bent out of shape when someone adds to the discussion. It's a public forum, discussion from either side is what happens.

In the end, it's all about what you're comfortable with.

I wasn't suggesting that your opinion is wrong. Nor was I suggesting that going darkside is what you should do. I'm not a die hard darkside supporter. Fact is, I've never ran on the darkside so I'm not advocating one side or the other. But like you, I want to try it and see if I like it. You did and didn't like it. And that's great for you. Having worked in the tire industry for many years, and the way you worded your post about the sidewall flex is what prompted me to post what I did about the subject. From what I've read, running darkside takes a bit to get used to because you are going from a very rounded contact patch to a much flatter contact patch. Again, I don't know for sure as I've not done it, yet.

As far as not knowing why there's not anyone local to mount a car tire on a motorcycle rim, I actually do know why. It's not because of a safety concern. The non motorcycle specific facilities won't do it because they don't have the capability to do the whole procedure. And the dealer won't do it because for one, the motorcycle tires cost quite a bit more than a car tire and it cuts into their profit margin, for 2 this particular dealer won't install customer parts of any kind (actually most repair shops of any kind around here won't) and they can't get car tires in. This information is what was told to me by my local dealer. The shop manager at the dealer runs a car tire both of his bikes and said if it wasn't for the company's policy, he'd do it no problem.

The fact of the matter is, as with most any subject, you will find supporters and nay sayers. There's always 2 sides to every story. It's kind of like the stock seat vs aftermarket seat "argument". There are some that absolutely hate it, and some, like me, that had no issues with it. Does that make me wrong? Nope. Does it make me right? Nope. It's opinion. And as they say, opinions are like butt holes, everyone has one. It seems you might have felt that I was trying to talk you in to going back to the car tire and was trying to convince you that you made a wrong choice in going back to the motorcycle tire. If that is the case, my apologies. Fact is I was just trying to give you more information you may or may not have had before. I meant no disrespect, but as Hayes said, this is a public forum and you posted your opinion. I posted mine. Nothing to get worked up over.

I didn't take offense. Just being facetious. My brand of humor. Now I've been schooled in forum decorum. Oooops, their I go again, being facetious. Lets all just take a deep breath, we'll get thru this, it will all be ok. Try to find some humor in what I posted. Not bent out of shape either. Life is to short to get bent out of shape over trivial things. Maybe big things but not these. I have a tire changer similar to the Harbor Freight one. Didn't have any problem changing either tire. As a matter of fact the car tire was quit a lot easier to change than the motorcycle tire. Again, not being any kind of expert, I suspect it's a liability issue regardless of what they say. Try to get them to put a plug in a tire if it's in certain areas. Well,this is my opinion and view, all mine, I'm entitled to it. If anyone disagrees with it, so be it, doesn't matter to me, their entitled as well and I respect that. If you've been shot at as many times as I have in a past life then what a few people say about you is really petty and trivial. Moving along, I wanted to see if anyone has any experience replacing the wheel bearings on the VV. Probably get stepped on like a cockroach..(meant to be funny). Doesn't look like you can get behind them to drift them out. IDK. The book calls for a special tool. Just wondering. Time for my chill pill...

The Altimax is notorious for sidewall flex. That's why I switched to the TripleTred. At least you kept an open mind and gave it a try though. Thanks for your honest opinion.

Have been using a OSHTU 205/60/16 for a year now, took some time to get comfy with it, now no issues. Like you Pilot I'll be going back to the Commander after this tire is worn out, the difference is, not sure what I'll use next. The Commander had 9k on it when I installed the CT and it still has 4/32 tread left. I figure to top 20k on the CT before it gets to the wear bars, its a 30k mile tire unlike most that are used that are 60k mile tires.

Rick, what's your reasoning for going back to the MT from the CT? Just curious.

It still has about 35-40% of the tread left. Changed it and went to CT because wanted to make sure had plenty of tread left returning from vacation last year. Did not want to get caught in heavy rain on the interstate with marganle tire. Plus wanted to try a CT, this my 1st time.

Wouldn't you know I would pick the wrong tire to try the dark side. Even with a different on I still don't think I'd like it. Hats off to all those who do.

what was your reasoning in going with a different SIZE than preferred tire size? do you think it added to your discomfort?

Leave it to me to pick the wrong tire. I thought the Genteral Altiman was the tire. Maybe that size wasn't the preferred size, I was worried about having sufficient clearance. It's hard to believe their would be a dramatic difference in the sidewall flex. It would seem to me that they all have some flex. I don't know. Anyway I don't think it's for me. Hats off to all who do. BTW, Amsoil
