Outer Limits 4x4 Board

just a question, are split rims ok off road? is there any problems, or dangers? I don't know much about them, but am a little wary, as they are potentially dangerous.
I have come across some 16 x 8 solid steel split rims, that were custom made, at the right price. I am thinking of using them with my 39 x 13 XML tyres. They will be used in mud, and some 4x4 work.
Any thoughts appreciated, thanks

Thoses that off road on split rims usuall run thoses second air bead locks. I dont know if they do this because of the dangers of the split rim flying to bits at low pressure or if they just loose there bead easy.

you have to use tubes with split rims, and you're more prone to getting punctures (dirt ends up between the tyre and tube quite regulary)

At least if you get a flat you can change it yourself out bush (keep 2 tyre levers handy, as well as tubes and patch kit)

the only dangerous part about them is if they arent put back together properly. when you put 35psi in them they can fly apart and take your head off.

if they are pout together properly they can reliably be run as low as 15psi, i dont know that going any lower would be advisable.

Splitties fine offroad.

I've run as low as 10 psi but would not recommend iyt as it was accidental, (read guage wrong )

Lowest press you really need is 16 - 17 psi anyway

And as previous,- much easier for repairs.

I am running a tyre with over 5000lb load rating each, on a vehicle that weighs just over 5000lb's, so I imagine I may need to lower the pressure a little.

They are dangerous if they aren't assembled properly. In the tyre shops is compulsory to have a cage to inflate the tyres fitted to splits after thay have been serviced.

If you are out in the bush and you service one of those there is no cage available, so if something goes wrong someone could be picking your head up some metres away fro, your body.

I wouldn't touch them.

Put it under your vehicle and then pump it up, preferably not directly under your fuel tank though.

Correct, they can be deadly.
But they are extremely common with experienced Desert/Outback travellers, to the point where lots of em swap Sunnys for Splittys. Check some threads on Exploroz on em

For the few saying it will take you head off .. if you take a modicum of care the are safe to reassamble as any other rim and tyre ... Like any piece of equipment, if driven by a moron it dangerous

when re inflating few things to keep in mind ..

1. turn the rim over, so the lock ring is facing the ground, very little chance of it moving easy 50 plus Kg of dead weight rime and rubber f was poorly assembled

2. pop a couple of ratchet straps around the rim tyre combo, if the lock ring does come loose you want to slow it mostly so you dont have a stell ring flyng through the air .. even a snatch strap warped around it will dampen the energy alot (think winch cable damping weight's)

3. The most important one of all .. take your time putitng it back together, grab the wire brush out .. give the ring and seating area a good clean and make sure that the locking ring is well seated before you start blowing it back up .. when the tyre has just a few PSI in it, see that the lock ring is covered by the tyre bead (look from a good few feet away no need to loose you head over it ) if all looks good go ahead and inflate it to you needed pressure and have a fun day wheeling ....

Most of the standard 4x4 commercial vehicles use them and have done for a very long time. If they were no good I imagine this wouldn't be the case.

The only trouble we ever had with them on our Landcruiser as a kiddie was when the inside of the rims went rusty and rubbed through all the tubes We always had them worked on at tyre shops though. Never did anything to them ourselves. Then again it was a soccer mum troopy and never went offroad

I worked for beaurepaires as a tyre fitter & 2IC for a while and one day another experienced tyre fitter was inflating a tyre in a split rim and the whole thing dissasembled.

Lucky it was inside the cage. It sounds awful. We though one of the cars had fallen of the hoist.

As said, I wouldn't touch one of those. The cage had to be replaced for a new one, so I don't think inflating one of those under the car is a good idea either.

Big transport trucks and semis still use them and so do some utes (some yotas and nissan), but cigarretes are also deadly and people still smoke.

Anyway, my 2cts.

Hello
I have them on my truck.Limitted tyre range now days to choose from.Due to being old style.Can now get a Simex in a 750 16,still wishing I can afford them.Best bit as mentioned is ease of repair of road.my family has been involved in trucks and off road vehicles since mosses was in short pants.There was countless times puncture repairs were done at home with truck split rims with know problems.With due respect to the potenial dangers the are still not a bad choice of rim.
Cheers

i am looking at some 16 x 8 split rims, to suit my 39 x 13 tyres. Any tyre will fit split rims, as long as the sizes are workable. I think I may let these slip, and get some normal rims, in a suitable offset.
