Tube tyres on a tubeless wheel

[rouppe]

Are your wheels alloy or spoked?
From what I have read on these forums, most dual purpose spoke wheels are tubed, except for some BMW's & import Yam 225's.
If in fact you are running tubes, I also would recconmend the Mitas E-08's, especially for road work.

My wheels are spoked. I ordered the E08's and have them in my garage. That's what sparked all this off because I saw my old tyres said tubeless whereas the Mitas said tubed.

I'll take a photo of the valve area and post it tonight.

Cheers, guys, Andrew

OK, solved. Just me being a great big dumb-ass.

The wheels are spoked, the spokes meet in the centre of the rim, and the valve has a bloody great nut at the base of it, all of which point to a wheel that requires a tube.

Sorry for being rather dim. Now I need to tell Motorad to cancel the Pirelli's cause the Mitas are going to work. Good thing its 3 or so weeks out.

Unfortunately I now have a useless tubeless repair kit which I'll have to put on the shelf and replace with a tubed repair hit. Also means I'll have to get a centre stand cause if I have a puncture out on the open road, I'll need to be able to take the wheel off...

Thanks for all your help guys.

Many thanks

Andrew

Don't put yourself down.
You're not that great.



The Mitaseses should be great.

I'm tempted by the E08 as a "roadie" tyre to the E07 being "dirtie".

Bugger! I would of really liked to be there watching when you tried out your tubeless repair outfit.See - tubed tyres are ok now aren't they?

I actually wanted to go for the E07's as they provide more opportunity off road. The E08's are really only firm surface tyres I think whereas the E07's should let you get into thicker stuff. Not that I can talk from experience... I guess I'll have to wait a bit longer before I get dirty...

Yes I can imagine the chiropractic bills after everyone falls about laughing...
Tubed tyres are OK but I still would have preferred tubeless. But there's no point wishing for something you can't have. If I want tubeless that bad I can sell the XF650 and buy a BMW. Don't want it that bad!

I have spoked wheels on my Nov. 1999 Freewind and the tyres are definitely Tubeless. The garage told me that using tubed tyres on a tubeless rim would ride round on heavy breaking and using them without a tube would leak air. I was also told that it would invalidate my insurance.

Not good really. If you have tubeless rims, use tubeless tyres.

Good luck :-)

The garage is likely correct, but that's not an issue for you as you will have tube-type rims. Pretty much the only spoked rims that are tubeless are BMW's fancy jobs with the outboard spokes.

Most of the tyre companies advise that it is OK to use a tubeless tyre in a tube-type application. You will have to run a tube and doing so will drop the speed rating one grade, as the tubeless tyres have internal ribs that will rub on the tube.

Frustratingly in NZ it seems that any tyres that suit the BMW spoked tubeless rims are only imported in the tubeless style, even if there are tube-types made as well; for example the Continental TKC80 in the 90/90-21 size... which may go some way to explaining the spate of people thinking they have tubeless spoked rims because they currently have tubeless tyres fitted.

I used to run a tube inside tubeless on the GB. was better when i had small punctures as i could wack out the repair kit. Ran no problems. Hope this helps

If your valve stem has thread visible on the outside you are running tubes.
If you have a spoked wheel then as Warewolf says, it's most probably a tubed wheel if it's not a beemer (> 650cc).
Motards in general come with spoked wheels, tubes and tubeless tyres from the factory - Invalidate insurance?

[Motu]

There are tubeless spoked wheels - modern trials bikes use tubeless tyres and have centre spoke rims.They are sealed around the spokes.I have heard of people sealing their spokes with silicone and running tubless tyres.It's not so much the tubeless tyre,but a tubeless rim is very different - they have an extra ridge to hold the bead in place,called a safety lip....for obvious reasons.

Thanks guys, very helpful information posted here.

Sounds like a load of bollocks to me. Do you really think that the factories would fit tubeless tyres (with tubes in them!) to tube-type rims if it wasn't perfectly OK to do so?
I have done well over 200,000Km with tubeless tyres on tube-type rims (XT550, XT600, F650, F650GS) and never had any issues, tyre creep or other.
And the Freewind most definitely has tube-type rims.

I would be very suprised if any of that was correct, normally the only construction difference between a tubed and tubeless tyre is that the inner liner on the tubeless isn't porus and they certainly wont ride around the rim on braking

You've got it round the wrong way... We're not suggesting there is any issue with doing it how you describe. The issue was doing it the other way round: a tube-type tyre on a tubeless rim.

As motu said, the primary difference is in the rim bead shape but I would expect some bead differences on the tyre, too, apart from the obvious one of tubeless tyres having much stronger & tighter beads which makes field repair more difficult.

There's shitloads of information on the web, go read it!

I've worked in the tyre industry for 20 years and get stuff sent to me so I don't need to

Dunno about Motorcycle tyres but there used to be no difference in car tyre bead construction between tube and tubeless tyres so I'd be suprised if there is in motorcycle tyres.
