Split rims & tubes

[Finly Owner]

Agree with the ferret on lock rings - real hard to tell if they are seated properly. One of the reasons I gave up on split rims.
For extra safety when inflating, slide the wheel under the vehicle, but not under the petrol tank. That way the valve can stay upright and no chains, etc. needed.
If you are worried about possible samage to the underside of the vehicle, put a bag or old blanket (always carry one) on top of the wheel.

But placing under vehicle you can't watch the bead ring? When they snap into place, its the pump, stop, tap, pump that assures it stays locked in.
I have done these on trucks. I have heard the horror stories. But 99% danger is removed by doing it in stages, and safely.

Yes, If you go about it in the correct way keeping safety as a premium, there is minimal danger, thousands are fitted worldwide every week.
The biggest danger was with the 10.00. 20 truck tyres, taking upto 100psi, many a lock ring has gone through the roof of various workshops and I know of one man being killed here in WA.
The best way is to watch an expert, ask questions and practise until confident.

Agree 100% have doneAcco rims at 100psi. No cage, no chain, no dramas. Lotsa tapping, lotsa caution. No stupidity! And yes shown and warned by old timer. Since have done more and shown others and they have never had problem

I used to work for Whimps tyre and mechanical many years ago here in Brisbane(and alot of other tyre and suspension shops). They liked to send there staff on seminars. I remember at one they showed a video of a site where the ring had come off. The person doing the tyre did not survive. What they actually showed was the ring embedded in the concrete above. Goes to show how much force is behind these rings when they let go. But with my past experience when pumping split rims up without the cages etc, it is easier to seat the bead with the wheel turned over with the ring facing down. The only major danger is when the tyre seats itself on to the ring. Once you are there turn it over give it a few good taps with a mallet and all should be good.

Be thankful they did not produce 4b's with suicide rims. A 4 piece rim that sill has a lock ring.

OK thought I might have run into @ the old Beenleigh one.

[Dhuck]

I was at Tyre Power there. I think it's Beaurepairs or something now

[Finly Owner]

On top of the hill? How long ago?

[Dhuck]

Christ mate they left years ago and about 23 years for me they were on Boundary Street

[Finly Owner]

Yep, on the hill. Geez, I was still riding push bike when you were working there. You have got to be in 40's or more.
