Thread: 130 tubed wheels / tubeless tyres?

I was of the understanding, at least for td5 130's, that tubed rims was standard issue.

My experience has been that tyre retailers refuse to fit a tubeless tyre to a tubed rim without a tube. That is not to say that some won't do it, and I have not hunted around to find someone who will.

Admittedly, I have never gone to low pressures so I can not comment on the issues of rolling beads.

I am currently looking at changing tyres to eaither a 255 or a 285, but I am torn....

Sssh, you'll restart the tube wars all over again

I had a tyre service suggest to me to do that very thing when I rolled a tyre off the rim after a puncture when running tubes, (and the tubes were pretty much welded to the tyres) and have several different tyre services mount new tyres in the same manner since.

If you have tubes in a tyre and plan to deflate tyres for sand work, firstly get a good brand tube, secondly get 1 size smaller tube i.e. 6.50-7.00 tube in a 7.50 tyre (sorry it's less confusing using the old tyre sizes) and don't go as low in pressure as you may have done in a tubeless tyre.

If you do use the smaller tube it is less likely to get pinched running low pressures.

Rick,
Its been ages since the 'tubewars' I vote we arc it up again...

Coming from another 130 owner running tyres on rims with a simple misprint on them - the factory just left four letters off the word 'tube'.

No way Im gonna change doing what works perfectly well from 50psi down to 15psi - on all surfaces. Compared to running stinking tubes that slow leak every second week.

BTW: be aware that there are two offsets in the 130 rims, all are 6.5". The current one has a positive offset and the early ones have a negative offset.

Are you sure ?

That's the first I've heard of it, I thought they were all 20.6mm positive offset ?

If they were 0 or negative offset wouldn't the tyres be outside the flares ?

The earlier type 130 rims look like they have heaps of offset, but I think it's an optical illusion due to the rim construction.

Damn, I had the opportunity to measure some a few weeks back and didn't

The Current 130 Rims ( really Just Land Rover Heavy Duty Rims ) are 16×6.5 inches

Then theres the 1 ton Heavy Duty Rims

130 F/C 2A/2B AND 109 1 TON 6.5 X 16 20.6MM INSET (ANR1534PM)

Theres also this one fitted to Land Rover 110/90.

ROAD WHEEL WELDED TUBE TYPE 5.5F X 16 X 33MM INSET (ANR4636PM)

569203 are also 2b FC Rims size is 6.5" x 16" x 1mm outset. but the 2b was also fitted with 7.50X16 tyres on 5.5 rims. Then some would say that HCB ANGUS and CARMICHEL Fire Engines were fitted with a Rim with more offset than the standard 2b rim.



So many combinations ...theres also one specific to the 127 Rapier... off set wise that is...

In my diagramme read "inset" for negative offset and "outset" for positive offset.



If you look at the original 130 rims ANR15334 they resemble the late SIIB 569203 rims although the bead area is about 2 1/2" where on the 569203 rim the same area is 3".

The late 130 rims have the rim centre reversed and have a positive offset.

The information on the actual offset on the 130 rims was provided by others, so now I'm going to have to measure the rims directly to check.

Diana, the current style 130 rim has an offset of 20.6mm positive.

It's stamped on the rims and I've measured it to confirm.
This means that the rim centreline is 20.6mm outside of the mounting face, or to put it another way, this particular rim has 103mm of backspace, ie. if you lay a straight edge across the back of the rim and measure to the mounting face it's 103mm.

As you know, standard 110 rims have a positive offset of 33mm (as does the Disco I) regardless of whether they are the 5.5" or 7" rim.
On the 5.5" rim the backspace should be 102.85mm, (I'll drag a 5.5" rim out of the shed and confirm this later) and the 7" rim should have 122mm of backspace. (this is why you lose steering lock with the wider rim unless you reverse the centres)

Positive offset means the rim centreline is inside of the mounting face, negative offset is obviously the other way around. (it can get confusing)





The two types of 130 rims you've drawn do indeed appear to look like that, I was comparing my rims to a '95 the other week but was sidetracked and didn't get the ruler and verniers out.
(The '95 was in for a service and I'd become the LR service adviser for the local tyre service. )

I think the later style centre has more outward curvature giving the impression it has less offset than the earlier rim, but if the earlier rims were 20.6mm negative offset they would give a track increase of 80mm over later rims, and that's up in 6x6 wide track territory.
Zero offset would yield a 41mm track increase, etc.
