Losing pressure

[XRS_SLED]

Keep losing tire pressure in the little tires on my two place sled trailer. I'll fill them up to the max cold limit on the weekend, tow it for a local ride and by the next weekend (after sitting in my driveway), they lose the majority of the air pressure?? Even my spare exhibits the same so I'm thinking it must be normal for these little 10ply tires.

Is this normal??

I used to have 5.30 x 12's on my 2-place and would have to add air a couple times a winter to keep them at max pressure. I would think you would be better to have a tire shop break them down and reseal them. Or, take them off and spray a water/soap solution around the bead and the valve stem to see if you can identify the leaking issue. I wouldn't want to blow tires out just because they got low on air and got hot.

Very common to have bead leaks on trailers that spend a lot time parked.
Pull the tire off the rim, clean it up and put it back on. Good to go!
