Talking about letting air out of tyres with split rims and tubes is a very sensitive issue and not a lot of people are prepared to commit to answer this question, so I won't be offended if you don't.
Q. Is it safe to let down tyre pressure in tyres with split rims/tubes?
Q. If you had split rims/tubes and were going beach driving, what pressure, if any, would you let them down to?
I currently run mine at 45psi. (Cheesecutters)

Daily @ 45. Thanks for that. I might have to go and ask a tyre dealer.Quote:

does your glove box user manual have anything in it for this?Quote:

If you go much lower there is a chance that the tyre can spin and snap the valve stem off, then you have a problem. Drive slow and don't overheat the tyre. Cracking wasn't a problem. If you have a spare tube and a compressor and a couple of tyre leavers, you're good ta go.,Tailor are running ATM too.
And a steel club hammer to tap bead as well.Quote:

Mind you i only drove less than 1/2 a K like this
Thanks guys. I've seen a couple of young guys change a split rim in less than 5 mins.
I've also heard they can be dangerous if you don't know what you're doing - and I don't.
That's why I carry 2 spares. One for normal and one for Justin Case.
Note to self. Carry 2 spare tubes.

All 6 tyres are split rims, and I'm guessing that if they carried a couple of spare tubes, that should have been enough to get them out of trouble - the equivalent of 4 spare tyres.
They're relatively easy to take out the old tube and wack in a new one and pump it up...if you know what you're doing.

Allways tap the lock ring to conform to the rim, put a chain or rope around it to prevent the lock ring becoming a missile, put 5psi in and tap tap tap all around and the ring closes right up,
then inflate to the final pressure, tapping as you go. Face the lock ring AWAY from you when inflating. Folk have died because of flying lock rings, if unsure, don't do it and as you say, carry extra spares.
