Soft sand / How much pressure on your tires?

rpriegu - 28-5-2013 at 08:46 AM

Hello everybody!
I noticed after riding on soft sand that in one of my wheels, the tube moved inside the tire (so moving the valve) what made necessary to dismount the tire from the rim to fix this and be able to inflate it again :( :( I understand that this could happen if you are riding with too low pressure.

So... how much is the minimum pressure you put on your tires if you are going to ride on soft sand? How much if you are using tubes or tubeless. :puzzled: :puzzled:

Thanks and regards

What type tires and wheels do you have?

In this case I was using some borrowed wheels that are Dunlop ATV used (19-7-8) (max inflation 36 PSI) with Starco plastic rims (max inflation 30 PSI).

When running Duro Bigfoot lites with similar wheels, I ran as low as 3 lbs and as much as 10. 6-8 was really optimal for most condition though. I ran tubeless and you can too.

I've ran mine with ZERO psi .. haha.. your problem is the inner tube. I ran my Nanco N800 tubeless also. Once those tires set on the rim, they are not moving.

Bob,
Well this ones can't go without tubes (they are too old and broken), but yes I know, if they where in good shape I could use them tubeless.

Van,
Yes I know the problem is the tube, so my question could be how much pressure do I have to put so they don't move inside the tire?
Don't you put any air in the Nanco? Doesn't your buggy get too heavy (I mean it has too much drag)?

Thanks for your answers

It could actually be that the tube isn't moving so it sticks to the tire and doesn't "center" while inflating. The old bike trick is talcum powder in th tire to prevent this.

To Vans point you may want to inflate slowly to get a good "set" between the tire and tube and then air down to pressure you want to run.

The Nanco have very tight fit on the ATV rims that I was using. Once they were seated on the rim, they are pretty much stuck on. The tires hold there shape with just the air that is in there, no pressure. They are not flat, just not under pressure. The walls of the tires are stiff enough that it holds my weight up without any pressure in the tires. I use to run it with 5 psi until I found out that they were the same shape with 0 psi. I actually have 3 nanco on aluminum rims right now that has the tire stuck on them. Been wanting to switch rims but I can't break the bead myself.

I use a special tool for removal, not as fun as the seat the tire explosion method.:lol:
