Tire and wheel size for push cart?

I believe you are right about 7 inch wheels. I picked up this cart and plan to clean her up, but I do have an immediate use for it and one of the wheels is losing air. I'll look into doing a patch of the innertube too, but sometimes taking apart the wheel can just result in the whole things becoming totally unusable until a replacement tube can be found.

I pulled off the offending wheel and cleaned it up so I could take some measurements and inspect it.

The wheel actually says 'Saginaw Products Corp' and has a grease zerk and bearings in it. It sounds like bushings were the norm for at least some sulkies and/or carts.

The tires are 4.10/3.5-6. So it seems that someone replaced the wheels somewhere along the line?

I tried taking it apart last night, but the tires seem to be bonded to the wheel halves. Anyone have a good trick for separating them? I was going to try a sledge and a block of wood to reduce the chance of accidentally whacking the rim.
