tires on my stock wheel 79 GS 1000? I have looked at the wheel but did not see any reference to useing tubeless tires.

Have Shinko R230 tubeless tire. What say ye experts?

Thanks,

Larry
 
i had to drill out the valve stem hole a bit. i've done it to a few so far. they all worked fine.
 
Yes, you can definitely use a tubeless tire.

However, the question you should be asking is whether you should also use a tube inside that tubeless tire. :o

The wheels on your bike were not certified for tubeless use, but, like the others have said, some have tried it and were successful.

The main problem is that the early cast wheels tended to be a bit porous, allowing air to escape. The use of a tube is highly recommended, but you might also get away with coating the inside of the rim with epoxy to seal it.

Also hinted above was the fact that you might have to drill the hole to properly fit a tubeless valve stem. Depending on the shape of your rim, you might also need to machine a recess for the inside face of the stem to seat properly.

There isnt a reference to tubeless wheels as they ARENT tubeless wheels. There missing the inner step inside the rim. Can do what you want but its only one more thing out there trying to get u killed. What would i know. only fitted tyres for nearly 20 yrs at Tyres For Bikes in Australia.

So what you are saying is that he should use a tube..is that correct?

Sharpy, while I respect your time in the business, I have to disagree just a bit. I used to think that, too, but I recently changed a tire on an '81 550L.
It had that "inner step", but was NOT marked "Tubeless Tire Applicable" like the rims are on my bikes.

I just put new tires a month ago on my 78 1000 and the rims did not say tubeless. I drilled out the stem hole to accept a universal bolt on stem. The tires seated just fine.

I personally don't see where there is any difference between the rims that say tubeless and the ones that don't.. except the hole and the stamp. I am under the impression that they did not make tubeless tires in 78, and that is why they didn't think to stamp the rims.

Sorry, but this is incorrect.

Tubeless wheels have a different rim profile. There is a hump on the profile so when the tire bead is seated it fits over the inner hump and is constrained on the outside by the wheel lip. If you deflate, the inner hump will keep the tire from separating away from the seated position on the bead. For this reason tubeless is safer.

I'm not skeered.
 
If you have a deflation at speed, neither tubeless or tubed is safe so whats the point, really.

Tubeless wheels hold the tire on the bead much better in this instance. Safer to be sure.

As to whether or not a tube will assist in a pressure loss at speed situation with a tube type wheel, that's debateable.

This is nothing more than my personal take on the matter. If at speed, running without a tube on a tube only type rim, you wouldn't have the added safety of a tubes ability to slowly deflate if the tire did get punctured.

I'm planning on running tubes on the GS1000E and do run tubes on the '80.

FWIW.
 
No, tubes don't slowly deflate. They go bang. Though some people run tubeless tires on the stock GS mags that otherwise call for tubes, I wouldn't do it. I'd get new tires, new tubes, and use Slime to prevent flats. Slime works well.

Not as well with tubes as without. Inner tubes tend to rip, or get longer cuts where a tubeless tire will just puncture. Sealants like Slime or RideOn can't do much to seal a rip or a slice, but it works great on punctures.

Of course it all depends on what kind of damage, what you run over, etc.
 
Running a tube in a tubless tire is moronic where one isn't necessary- you actually lower the tires effective heat range and add in, an unsafe situation to a relatively safe one. Not to mention shortening the life of the tire and quite possibly your own.
Be aware that fitting a tube reduces the speed rating of the tyre, so a W-rated tyre that’s good for 167mph, becomes an H-rated tyre that has a maximum rating of 130mph.
