As odd as this sounds, I think I have porous rims on two of the tires
on my Ranger.

Anybody know if you can use tubes with radial tires?

I think it isn't recommended and may void any warranty. Check to see
if you have a leak at the bead or the valve stem.....

It's not that - there aren't any leaks around the rims or the valve
stems - first thing I checked. There doesn't appear to be any
external causes like a nail or such as that.

I pulled the rims off and am taking them to the tire shop and have
them looked at. The reason I asked is because I had a problem with
one of the rims on my F-250 (aluminum) which went porous - no
apparent warning. When they pulled the tire, you could see the small
area which powdered - you couldn't see it from the outside unless you
knew where it was from the inside.

I had heard that you can't use tubes with radial tires which is why I
asked. I'd hate to have to buy new rims - those things are expensive
and I'd have to get four of them to match.
