Really? Do you know anything about tires?
Road temp, ambient air temp, humidity, vehicle weight, road surface, heat transfer through the rim from heavy braking all effect tire temp and pressure. Friction causes heat the heat cause the air to expand which makes pressures increase. From cold to hot tires can have up to a 12 pound swing increase in pressures. To be under the illusion that tires have a correct operating temp is ludicrous
I'm not getting involved in a slagging session, I just offered my opinion from past experience.
If optimal/correct tyre pressures weren't important, motorsport competitors wouldn't check and reset their pressures between runs or in the case of rallying, between special stages. Did you know, that over inflated tyres reduce the contact patch? Of course you did!
Amen, amen.
And if he does fit a tubeless tire WITHOUT a tube, it will work just fine...
As I said, many here have done and still do it....

Poor example. They adjust to change temps, road conditions so the tire performs the best for there setup not the best for the longevity and performance of the tire. Very few use tires that any of us would use in daily life. I have a tire lab at work and I work with prototype tires. I'm a test driver tires and there performance is a huge part of my job. How many people here are competing in motorsports with there 30 year old GS in a professional motorsport?
True...that's why I take the risk of riding at all...
But I have yet to see what you are worried about...
Seriously, I just don't understand why you think it is an issue...
Either you did not make a case, or I did not understand it.
I know personally, and have read of, many, many people that do this...people that ride hard.
I have NOT read or known anyone that had an issue due to running a tubeless tire on a tube rim without a tube...not one...ever.

Since I am the OP, I am going to state what I am doing to do. Per the info posted here and on other forums as well.

Where are you guys finding tube or tubeless on the rim?
All i can find is 19x1.85 DOT, Enkei, Made in Japan, Suzuki "S"
1980 750GS w/ aluminum wheels

The rims with the extra tubeless bead will state "tubeless tire applicable" or something to this effect. If it doesn't say this, the rim is tube type.

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.

Yes there are lots of gurus but take responsibility for you own life and do research. Tubeless rims have a step on the inside to hold the tire in place. 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.

You can run tubless on spokes. Lots of Silastic and ducttape. The boss ran them on this for over a year but when i got it i fixed it to run tubes.

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.

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...
