Thread: Perentie - Tubeless Tyres

Hi all, I also understood that the tube type rim was riveted to the centre and that the rivets were not guaranteed air tight, hence the need for tubes. If that is the case, would some sort of sealant like Tyre Slime or Fix-a-flat solve the problem of air leakage or would it create more problems? Cheers, 130man.

Some rims are rivetted, some are welded. I have no experience of sealants with them, but I assume they would work. The only downside is that you are unlikely to be very popular with the next tyre fitter to change a tyre on that rim.

Does this include the landrover rims marked with "tubed" or "tubeless"?

Of course not - but none of the 25 or so Landrover rims I have have these marks.

I have four sets of rangie and disco alloys. All the double hump rims are marked "tubeless".
The set without "tubeless" not only are missing the second bead, but they have a size of valve hole that doesn't fit common tubeless valve-stems.

I can also add that tubes can be very hard to find in many cases, so you are faced with patching one you would prefer to replace. Then there is the cost. My experience is that tubes have almost doubled in cost in the last five years - recent quotes being $36 each. And if anything the quality is worse

I carry tubes for emergencies when on trips away and my series vehicles all run tubes. Either Bridgestone or Michelin tubes only and these are available if you order them.

Are the ribs on the inside of most tubeless tyres an issue when running tubes?

Yep, they certainly are, wear holes in the tubes eventually especially if you are running low pressures and the tyres are flexing a fair bit. Not as much of a problem when running higher pressures. Running tubeless is the best way to go and carry a spare tube or two and a patch kit for emergencies when in remote areas.
