Tubeless/tubed tyres

Fitted tubeless 205x16 to my tubed type rims many years ago and never looked back...no tubes fitted Std Series LWB rims.

My mate runs the same...not a problem... won't come off the rim believe me.

Much more reliable than have puncher prone fast deflating tubes...and a big weight saving.

This makes you a ****ing moron.

No its not....I am aware of the beads....nonsense.

How the bloody hell does a tubed tyre stay on if the beads are so important.

Been on mine like this over 20 years...

It doesn't stay in place that is the point! The inner tube holds it in place when inflated and once flat nothing holds it in place and it comes off! I have had the tubed tyres puncture and drop itself into the centre of the rim making it undriveble, and seen tubless tyres stay in place and shred the side walls because the driver did not notice it was flat until there was very little tyre left. The danger of running tubless on tubed rims is you do not need a puncture for this to happen, lateral forces can push the bead into the centre as nothing is there to keep it in place.

No guys I don't think you thinking this though.
And please no need to been downright rude....I have owned and driven landrovers for 50 years.
I remember tubeless tyres coming on the market...no so call safety bead in therose days.
Ok lets try again...you have tubes inside your tyres... you get a bolt trough your tyre...the TUBE goes down in no time.
At that point, you're in the same position as me with my tubeless tyre on a rim with no bead...think about it.
A tubules tyre on my rim with just 5psi...you will never unseat it.

No need to say any more...if you dont understand it not my problem.

Tubeless rims have bead retaining ridges because kerbing a tyre can momentarily knock the bead in and break the seal leading to a sudden deflation. Tubed wheels and tyres avoid this because the bead can move but the tube holds the inflation. The same is true if a tyre is under inflated, the bead retainers on a tubeless rim will hold it in a corner, on a tubed the tube holds even if the tyre moves. Its all gone into in some detail in things like the ETRTO techical standards which are very clear; tube rims must always be fitted with tubes regardless of the tyre type, it is the rim that determines when a tube is fitted (although obviously you can't run a tubed tyre tubless as they are not airtight). ERTRO is imporant becuase it is the industry guidance on what is safe, the legal requirment is to comply industry guidance and be safe. ERTRO specify all the rim profiles and what can and cannot be safely fitted to them.

Well plenty of off-roading and bumping off and on lots of kerbs later.

I think some people may look for problems that may not excist...dont believe everything you read in the news papers.

Ok you barreling down the motorway in your landrover with your wheels that contain inner tubes...on tube-type rims.
You get a puncher the tyre goes flat quite quickly as tubes have zero self-sealing my tubeless tyre do.

At the moment with your now flat tyre with its now useless inner tube....why is that punchered wheel and safer than my wheel...that is far less unlikely to get a puncher in the first place.

Yes get the picture....dont bother with all that HS bollocks....live in the real world...isnt that why we drive old landrovers.
