    Tubeless tyres and non-safety rims?

    I would be interested in wiser people than me’s thoughts on the advisability and legality of fitting tubeless tyres to the non safety original wheels on my ‘80 RRC. It will not be used for anything too stressful anymore as, while it is a long way off being perfect, it is reasonably original and too nice to damage.
    Another option I am considering is D1 steel wheels, or getting D1 rims put onto RRC centres. Any opinions on these ideas would also be welcome.
    Thanks,
    Woolly.

    I ran tubeless tyres in my Defender , on 'tube type' rims, without tubes.

    I run tubeless on my Series 3 with standard riveted rims,

    Same on my Caravan , which runs Defender rims , Had a blowout & bugger all remained of the tyre tread and sidewall but the beads were sill in place , so it was not a failure of rim non compliance.

    Also surprisingly, my 1949 Dodge ute is running tubeless tyres on original 16x5" riveted rims. No problem whatsoever.

    Tubeless tyres were introduced long before the ridges on the bead seats to keep the beads on, and these were not associated in any way with tubeless tyres when originally introduced.

    As far as I am aware there are no regulations prohibiting the use of tubeless tyres on rims without these ridges, and as a couple have already posted, this has been done for decades without issues. I do not have any fitted that way at the moment, but I have had for years, with no issues.

    Many tyre fitters though are reluctant to fit tubeless tyres to rims that are without the ridges, probably because of potential liability risks.

    Absolutely fine and not illegal - although some tyre places will tell you this. It is only illegal to run tube type tyres without tubes - that's in the Vicroads RWC manual. Fitting a tubeless tyre on an older rim without the safety bead is fine.
    If you need to contact me please email homestarrunnerau@gmail.com - thanks - Gav.

    A topic well covered before.
    Everything everyone else has already said, its fine.

    As with Goingbush, I'm running tubeless tyres (no tubes) on my old 1963 Series 2A, riveted wheels and they hold air just fine.
    Regards
    Daz

    I've used tubes in tubeless tyres on rims without beads since my rallying days where many a tyre stayed inflated after the tyre was partly pushed off the rim leaving dirt and gravel wedged between the tyre and rim.

    Thanks for the responses everyone; seems I was being over cautious. Will try to find previous comments on topic that Daz referred to, should have thought of that first.
    Thanks again,
    Woolly.

    When tubeless tyres first hit the market in the 1950's they were fitted to standard rims not "safety rims". There was a firm in Barry Parade Brisbane called Miricorp Miracle Safety Rims that converted your standard rims to safety rims by rolling the beads on the base and repainting. They advertised heavily in the press and on radio (before TV).

    Tubeless tyres were distrusted by many for decades. Lots of motorists insisted on tubes being installed in tubeless tyres particularly in rural areas where then there were almost no sealed roads..

    Ironically tubes are more prone to punctures and leaks than tubeless tyres. Thats my experience anyway. The only reliability issue I had with Toyotas was flat tyres , can't run Tojo split rims tubeless. I've never had a flat tubeless tyre, (except the blowout on the caravan)
