4.80-8 inner tube

[danderson]

When putting tubes in a 4.80-8 tire should the straight or 90 degree valve stems be used?

I'd use straight valve stems.

I use straight.Easier if you have a T-shaped fitting to screw on the tube once you get the stem threaded through the wheel.That will keep it from sliding back through the wheel while rolling the tire on the wheel.Also sprinkle talcum powder on the tube and inside the tire.This will help prevent pinching and let the tube conform to the tire easier.

One more thing in addition to the above great advice...when using tubes, air up the tire/tube/wheel assembly to the max sidewall pressure on the tire when you first assemble it, then remove the valve core, let out all the air, and then put the valve core back and air it up to the desired pressure. This should ensure there are no folds in the tube that will cause it to quickly fail.

Thanks all

Those of you running 4.00-8 tri ribs what pressure are you running? 12 doesn’t seem enough.

My Deestones say max pressure is 2.3 BAR , or around 30 psi. I run mine around 20-25 psi.

I put 25 in mine. That looks better. Thanks

I second (Or third) the use of straight valve stems in those tires. As long as there is nothing for it to hit or if its on the outside. I only use(live with, consent to be aggrivated by) bent ones if a straight valve stem would hit something.
