My 82 850 says tubeless applicable, my 78 1000 does not.
I dont run tubes in the 850, I do have tubes in the 1000.
I do what the wheels tell me. The wheels are the boss when it comes to tubes.

This seems to be an area where every internet guru has a different answer.
I asked the internet, and (on average) it said sure, you can do that. So I did, and for a few days now that seems to work just fine. Tyres sit nice and tight where they're supposed to, and they hold the pressure just fine.
What is the problem? Will they come off at high speeds?

the original question was can i use tubeless tyres on a tubed rim, answer NO........but he did not mention putting a tube in as well, that changes everything, although i still wouldnt risk it

Back in '79, when I owned my '78 GS1000E, I believed because you had aluminum wheels, you could run with tubeless tires, and because the tires
stated tubeless, why use tubes? so I used tubeless tires without tubes. Both aluminum wheels and tubeless tires were fairly new technologies to motorcycles, there was no Internet, no GS Resources forum to tell me otherwise. I did not have any problems either, I ran for extended periods at very high speeds. 90 was a good speed to cruise at on the Interstate.
Today, with my '79 GS1000E and '82 GS1100E I still run tubeless tires, but I now use tubes. I do so because the service manual and parts fiche show tubes in the parts breakdown. I guess I use that as the final authority,
and I no longer cruise at 90 on the Interstate.sigpic

Sure tubeless tyres fit but just because you can doesnt mean its a good idea. You can fit non OEM gaskets on a engine rebuild, you can swim in a creek in the top end of Australia, you can sleep with a hooker without protection but the more you know the less likely you will do it. And go and have a accident and let the insurance company find out what you have done, might make you think twice.
So fitting a tubeless tyre on a cast 1979 tubed rim, with a tube in it, is stupid?
This thread, on average, leans towards this being perfectly fine.
I have a lot of faith in the experts here, but this seems to be one of those things where people have strong opinions both ways, and I am doing my "research" irl. I have CLEARLY stated that I think this is a safety issue, and that I will seek expert advice elsewhere. Why the load of sarcasm?

Maybe i missed read your post about having a tube installed. Thats totally fine. Sorry Just running a tubeless tyre on a tube rim isnt fine. As far as a expert opion is concerned im afraid i do qualify as a expert as i have worked at that above shop for about 18yrs in total and it was my job to do the mountings after that i was free to work on the race bike. I just banging my head against the wall with people that fit tyres to there bikes that dont comply. Its just one more thing that can go wrong on a dangerous hobby/sport. So basically if its not my bike and personally i dont know anyone, go right ahead and fit what ever you desire. I give up watching in here every week someone starting/asking about such a open and shut case. differant strokes for differant folks as they say. Over here the smart bikes shops WONT do a roadworthy on a bike thats not safe reguarding that tyre/wheel issue.

Cool. This thread seems to get everybody's adrenaline up a notch...
I apologise if I have seemed cocky or deceitful in any way, I only want to be as safe as possible.
I take it that as far as GSR is concerned, a tubeless tyre on a tube rim is totally fine as long as there's a tube in it. Thank you all for your input, and sorry for the semi-hijack, ScrumDown...

By the way, for all the newbies reading this thread, we have had this exact same discussion/argument several times before in different threads. It's always best to perform a SEARCH for the answer to your questions before starting new and redundant threads, particularly on touchy subjects such as this which gets peoples blood boiling.Ed
To measure is to know.

Sorry if I raised anyone's blood pressure. I did do a quick search and didn't did fine what I was looking for. But, I may not have used the correct search terms. That said and please correct me if I am wrong ...
From the postings here and elsewhere ... It is safe and OK to install tubeless tires on tubed rims as long as you install a tube. It is a lot less/not safe to install a tubeless tire w/o the tube on a tubed rim*.
*(although it can be done but not recommended)
