Split rim minimum pressure

dunno but I have used 12psi before. I think the generally accepted min is 15 psi

Mike it would depend on the ply rating of the tyre but it would be possible to run 8 PSI at slow speeds in very soft sand or snow for extra flotation.
Agree with Davoe 15 PSI is the usual minimum for general sand driving as most skinny tyres on splits are bagged out pretty well by then on a Cruiser.
Cheers Craig.........

have not used splits for years & never on a new type radial (used to be rags in those days) but found on sand i could go as low as 12 psi and never had a problem but on rocks etc anything under 18psi often chopped the valves off but never had a rim split/come apart this was on a Austin champ, half finger, 72 cruiser, 82 troopy. i hope this is some help

Hi Mike,
I have a TD 79 Cruiser ute with splits. I have never had to have them less than 30 PSI even in soft sand in the late afternoon. Having said that I would drop them down if required to get out of a situation. In many ways you are better looking at how much they are bagging and how hot they are getting. If you can't touch them they need more air. You can rip the valves off if the tyre spins on the rim and at lower pressures you can get sand in them and end up with a puncture shortly afterwards.

As always this all depends on speed, load, conditions.

I have yet to be advised to lower pressures on splits to under 30 psi though I have been told not to go under 30 psi several times. Be very careful driving at any speed at lower pressures.

hi mike w
i used to run my split rims as low as 8psi in soft sand its very unlikely the bead would come off because of the way they are assembled this was on the grey painted rims i have heard of tyres slipping on the chrome rims and chopping the valves off as always remember the driving conditions and adjust speed to suit
hope this helps
