Minimum tyre pressure for split rims

Hi Russell,

I run splits and would not drop them below 15 psi(unless I am in real trouble) as one runs the risk of running them off the rims. It depends what load you are carrying. I regularly run at 15psi in sandy country. On the Canning I ran 15psi only a couple of times and mainly 20psi as some of the dunes were quite hard packed. Down along the beach south of Robe 15 psi was best. At low pressures you have to keep your speed down as well.
Cheers,
Willie

Yes, I concur with the above reply, 15 to 16 would be the absolute minimum for heavy mud and or maximum foorprint for gnarly hills. Around 24-25 for general track/bush work. Of course, the big pain in the arse is the tubes, which are the weal link in the chain. At lower pressures they rub inside the tyre and will let you down, even when pressures are restored to road pressure back on the tar. Viva, a la tubeless!!

I have dropped mine as low as 10 psi, but only to get up Big Red fully loaded, only going in a straight line. But increased pressures once I was over.

I normally use 20 on sand, 15 for shell-grit beaches is the lowest I've had to go with my splits. For the same conditions with the 10R15s on my old 60 series, I've gone as low as 6 psi on the shell-grit! (Using the same gauge, in case anyone's wondering)

Cheers

Thanks for the replies. Confirms the thoughts I had - will pass on to my split rim mates.Russell S

10psi when your in trouble 15 - 18psi over a long period the tube rugs against the tyre and you get rubber dust in the tyre can cause flat tyres if you drive for a long way like that. put some baby powder in ther help slip.
tubeless much more flexable
cheers
