Air pressure on Montana Tires

[LonnieB]

Ken, were the tires and wheels removed and put under water to check for leaks? They may be leaking around the beads. On some tires there are some very tiny holes in the sidewalls close to the bead, that are part of the mfg. process. I have seen these leak also. If these holes are leaking, the tire mfgr. should warranty them. I would use tubes only as a last resort.
