Running tubeless on tube type rims

CHT there is a good reason why the mines do not run split rims,they are a stupid thing on a vehicle that goes in mud,you can't balance the stupid things,they never run straight because of the beating they get trying to get them apart(see the first reason) and since changing to tubeless we get one or two flats a week instead of a dozen.Ever wondered why they are worth nothing? tyre shops give them away for free.And just to add there is not many places I haven't been in an LR and I have never rolled a tyre off a rim or have it fall apart or go flat or whatever.

what pat 303 said....

tubeless tyres are also normally
easier to balance,
easier to change,
run cooler
tend to have a higher speed rating
and are usually a softer ride.

up to a point a tubless tyre is easier to repair but once your past that point your pretty much cactus if you dont have tubes to hold the air in.

my road rubber is tubeless my play rubber is tubed. (then again my road rubber is on on piece rims and my play rubber splits.)

I think driving style may come down to it a little as well but safety beaded rims would be a much safer way to go You can stick ya tubes where the sun don't shine!!!. Pat

The only info I could find quickly was that in the US, a tubeless tyre must be fitted to a safety beaded rim for DOT approval but in the Vicroads rwc requirements I cant find any reference to it.

I have read something somewhere about it, I will find it but I recon when I do this thread will probably be dead.

I did find that RWC in vic you dont need a spare tyre fitted, I knew I would find it one day so I was wrong on that one but then again, it was my old boss that knocked back the guy with the truck I was talking about in that thread. :p

One thing I would like to add too is what is the point of a safety bead?.If the tyre goes that flat you are not going to have control anyway so who cares if it comes off the bead. Pat

...........Im still trying to come to terms with **** is the benifit of not having a tube fitted.

The major benefits experienced are;

1. easier and quicker puncture repairs, and

2. no tube abrasion on the inside of the tyre (which leads to the usual flat tyre inconveniences) (and don't tell me about the use of powder/french chalk etc)

myself and my family have taken to using Disco1 wheels on our 110s to overcome all objections re tubeless use and tyre size from the rulekeepers :)

otherwise, we have had no negative experience in the use of tubeless tyres on standard S3 and 110 and Def rims - they have all provided airsealing

the point of the safety bead it to retain the rubber on the rim and not let it go flogging off the instant it goes flat...

you might only get 100m out of it but thats usually enough to start getting the vehicle under control....

without them its possable to pull the tyre in bend the rim and then pull the tyre off in exceptionally short order.

with them you usually get that critical few seconds where your driving the rims on the rubber of the sidewall and the treadface that lets you maintain control...

once your metal on the road your going where ever the hell the one remaining good wheel wants to take you and if you happen to be on the brakes at the time thats usually into oncoming traffic or into whatever the hell is on the left hand side of the car at the time. this is especially true if it happens on a front wheel of a front wheel drive car.

I looked into this after discovering my 110 County was tubeless on the original (tube required) rims. One thing I found was that 2 out of 3 tyre shops do not know what they are talking about.

It is definitely illegal to run without tubes on a rim that was not designed for tubeless tyres (contravenes the Tyre and Rim Standards Manual and hence ADRs if I recall correctly - I eventually found the info). So... at your own risk and if you have a serious accident pray the insurance company never finds out.

I am aware of the practice in the mines re tyres and rims. I was referring to a significant number of farmer's fwds that I have come across - including current model V8 cruisers - and I am not advocating the use of split rims simply noting what the cocky's are using. FWIW the SAS use split rims and tubes on their LRPVs (6X6 Landrover Perenties).Like you I have never had a problem with flats anywhere in the country - 45000ks over a year mostly in remote areas and the spare hasn't been off the wheel carrier (In fact it has not been required after three sets of tyres). As an aside I have spoken to a number of opeople who have commented on the fact that when they either used Landrovers, or changed to Landrovers from other makes of fwds the number of punctures they suffered dropped signinificantly.

At least we can choose.I know what you mean about the spare,I rotate all 5 of mine or the spare will never get used. Pat

I have also noticed this, but I think it applies to whatever make you are driviing, and I have put it down to better roads and better technology tyres - Laurie
