Are tubes okay in tubeless tyres?

**UncleHo** · 16th November 2006, 09:35 AM

G'day Folks

Well here's my 2 cents worth, the fitting of tubes to tubless rims would depend mainly on the rim type, I.E. Mags etc, but on standard type steel rims there should be no problem, the Army had fitted tubes to all it's Olympic Steel Treks, and they were on well abused vehicles and rims, if you bend a steel rim that is fitted with a tube you don't loose air pressure, I have run tubes in ALL of my tyres both conventional and radial since the 1950's and can remember that Pirelli recomended that tubes be fitted to all rims when they first released the Centurato, and Michilen released the "X" in the 60's and they were being fitted to rims that sometimes were not even rated as "Safety" rims, I have never blown a tyre that was fitted with tubes, caused by the tube.

cheers.

My Disco 93 V8 stock rims.
There's a tube in one of my tyres, been there for three years and no probs.
(The tyre was new, but got peppered by crap at the tip, tiny holes, too many to fix, lost about 5 psi a day, so in went a tube).

The guy who put it in was a local 'pinkslip' person.

it IS NOT illegal to fit tubes to tubless tyres. however it is not reccomended.

It IS illegal to fit tubless tyres to rims not rated for tubless tyres. Its not only illegal, its impossable as a tube rater rim has holes in it for assembley reasons and wont hold air.

So sayeth the Tyre wench at work who knows more about tyres than I know about breathing and drinking.

Interesting, comments,
but still no word on the written word that actually says it is illegal.

heres my two bob's worth
I had a puncture fixed in Port lincoln and drove it back up to Darwin then drove around on it for a year or so then put new tyres on it.

fella putting the new tyres on it went off a bit so I politely told him I wasn't the one who did it so don't get up me, when he settled down a bit he spoke of heat dissapation and how dangerous it is blah blah blah, I explained that I had driven back up during the build up with the road temp easily over 60C' for over 3000km and then put another 15000 km on it. I think he didn't believe me from the look he gave me? so I guess thats his problem not mine, but what he was getting at is that it could be dangerous

I dont know if that has helped even slightly other than to out line that tubes have been fitted to tubless tyres without disasters

Rangie steel rims with tubeless tyres fitted hold air without tubes no problems, previous owner did this to my old rangie but i fitted tubes for safety.

I was refering more to split rims, 2 piece rims and the flat center rims. If its got the safety bulges on the inside of the bead seats it tubless rated...

ADR's to follow, I'll ask the tyre wench on monday.... unless i find em online.

Rangie steels are not JJ tubeless rated.

**Blknight.aus** · 17th November 2006, 08:37 PM

I always thought they had the KK ones...

I freely admit that other than knowing how to bodgy them to get em home tyres are a little bit of a "yeah theyre the black round things on the ground put XX psi in them" deal with me but so far as I can tell the difference between a JJ and a KK is the depth of the "dish" in the middle of the rim with the JJ's being shallower. From what I rememer any rim with the double letters is rated for tubless.

can you get me a pic of a rangie rim without the rubber off and the code from the rim, lets see if we can throw the tyre wench a curve ball.

Conjecture and hearsay, tyre fitters may be very good at fitting tyres to rims, but may not be versed in the legalise of the court, as in an actual law (or several) pertinent to ADRs. One would expect that ADRs actually mean 'Australia', not state regs. as John E said and quite correctly - what is the ADR re this issue?

If an ADR exists then apply it, if not then no issue -

a flat tyre is not an issue - its only an issue if you have the choice between sleeping in the car overnight or driving home, tubes here are not the issue, as many before have described, tubes work in 'tubeless' rim/tyre combos, your personal safety is.... another issue...
