There is a difference between a tubeless RIM and tube RIM. There are a few different shapes out there designed to support one or the other.

This will only be a problem if you have older bikes... 80's and earlier because the rim shape may not adequately support the tire bead of a tubeless tire. There are almost no tubed only street bike tires being made... and haven't been for a couple of decades.

For our Drifters, the OEM rims are designed to use TUBELESS TIRES, with tubes and rim strips. Only BMW - as far as I know -  makes a spoked wheel that can go completely tubeless.

ALL brands of tubeless tires will work on these rims... but you MUST have a rim strip and tube because they are spoked.

That is true..but that doesn't mean you can always use a tubeless tire, even with a tube in it on a rim designed for a tubed tire.

As far as I know, John, yes you can always use a tubeless tire, on a tube-type rim, with a tube.  I can't think of any reason why you couldn't???

However Avon have stated to me that their Cobra tires can be used with a tube..A statement that I have filed away for use if Michelin ever stop making the Commander II to fit the Drifter.

John.

To further that statement, any tubless tire should be OK to use with a tube.  NOT the other way around, though.

Actually it is even worse than that..tubed tires have a different shaped bead to tubeless and the rims on tubeless wheels are shaped to accomodate this, so even if you buy a sealing kit to prevent the air from escaping through the spoke joints the stresses on cornering can cause the tire to dislodge from the rim..to sum up..

Spoke sealing kits are generally only made for pedal bicycles and you should not use a tubeless tire even with a tube in it on a spoked wheel..

There are VERY few tube only tires for street bikes. Nearly all street bike tires are TUBELESS. For wire rims, we have tubeless tires with tubes in them...

The exception would be if someone had the rim modified to seal it up. If you had a tubeless without a tube on true wire rims, you'd have a flat tire!!

I just noticed I have a tubeless tire in the rear of my 1500 Drifter with stock wire rims?

The tire is a dunlop 491 II tubeless belted.

I purchsed the bike with this tire on it.

I thought all DRIFTERS had tubed tires?
