Head Scratcher??

[aaluck]

My left rear tire is giving me fits. Every couple of months it will lose air for several days (sometimes just a day) and then just stop. Example: Last week it was low so I filled it, next day low again (and I mean visibly low), this went on for about 4 days. Filled it on the 4th day and now its holding air perfectly again--for now.

I have used several gallons of soapy water and sprayed the tire to near clean condition trying to find this "leak".

Has anyone else experienced this and what did you do to find the leak?

I had that with my BX25D ........
and I have had that with car/truck tires.

IF the "leak" is pointed down, it leaks more - if the leak is up off the ground it leaks less. OR something like that !

Check the valve to - soap around that and you may find it leaks.

I swear by Green Slime. I think I have it in just about everything in my garage that has an inflatable tire.

I too use a lot of the green slime .......... have used almost 2 gallons over the last 3 years!!!!!

Yes, no sense in buying it unless you buy the gallon size jug with the pump top. I'm on my second gallon too, lol. I make notes or mark what tires I put it in so as not to surprise the tire guy when the time comes. Tire guy years ago told me he appreciated that with the old school aerosol fix a flat.

Is the tire loaded? If not too much trouble to remove you can always pull it and place in a baby pool / trough / or larger body of water or something to chase the leak…if it leaks it out in a day I would think you should be able to hear it maybe. Are you sure it’s not a sticky valve core? Just some thoughts if not tried them or something similar. Good luck.

maybe do this...
break the bead , scuff up the powder coat on the rim,add 'bead sealer',
do it again for the other side of the rim/bead.
then blow up the tire, leave 'over pressure' for an hour, then reduce to normal pressure

It sounds like a rim leak to me. Doing as GreensvilleJay mentioned will probably be the ticket. There is also a chance that the valve core is bunged up and needs replacement, as mentioned by
rc51stierhoff.
