Harbor Freight claims to have the metal 8" wheels w/solid tire for under $10.00
Probably less than I paid for the tube, but I had the tube, plus solid tires can suck at times by vibration transfer.
Years ago I did repair a double wheel wheelbarrow with new wood handles because of a buddies stubbornness.
He borrowed my wheelbarrow and threw it in the back of his pickup.
I mentioned I thought he should tie it down and he said he wasn't going far or fast.
Well, he went fast enough for the air flow to suck it out of his truck and break the handles.
Lucky no other damage to anything or anyone and he bought new handles.
I did the repair and got to use that several times, in our discussions, for years.
