Aluminum rims corroding, leaking air, help needed

[Schurkey]

I hadda buy solid tires for my lawn/garden cart.

Can't keep Father-In-Law's snow blower tires aired-up, and the same with my buddy's stick-and-branch chipper.

I've got multiple hand-trucks that need the tires filled every time I use 'em.

I put new front tires on my JD D170 riding lawn mower. One holds air pretty well, the other needs filling about every month.

It's like trying to keep a small-engine carburetor in tune. Near hopeless.

Are those the foam filled type? I bought a couple of those for a stump grinder I built and they were worse than having to air up flat tires. They get flat spots overnight.

I don't know. Kinda assumed they were solid rubber. I haven't noticed them getting flat spots.
