Source for 1"inch diameter bore hub?

Hi Everyone! I posted before about a garden cart I have with a 1" inch axle. The tires are 4.8-12 and I have some tubes on order. However the local tire places don't want to install inner tubes, even though they don't carry the tire size. Anyway, my son and I have tried for quite a bit but are unable to get either tire off the rim, or even just get one side off (so we can stick the new tube inside). My son joked that maybe we should just get a hub that has the 1" inch bore (no key) that takes us to a 4 or 5 lug so that we can just get a regular sized trailer tire. After working, unsuccessfully, to get the tires off the rim, I'm thinking maybe that's the best idea. But I can't seem to find a hub with a 1"inch axle bore. So I thought I would come here to see if anyone here has any ideas or sources that would help. ** The reason we ordered the inner tubes is that being a senior on a fixed income, I'm trying to get this done without spending too much. In any event, thanks to all in advance who offer help & advice

Break bead on both sides of rim. Push bead toward center of wheel (it's narrower there). Start prying bead from rim. Liquid detergent sometimes helps fight friction. Plenty of YouTube videos out there on changing small tires.

Thanks everybody! I did think about getting a smaller tire, like the ones from harbor freight. The problem is that whoever made this cart (definitely home-made) has a front caster mounting to a frame that is/was level with the cart when the two 4.80-12 tires are on, and those tires with the wheel/rim stand almost 20 inches tall. Putting on a much smaller tire would result in a cart that was tilted to the back. I'm not saying that won't be the eventual solution, but the front caster wheel assembly is welded on. Still going to try using the innertubes but I did notice that one of the wheels/rims has some sharp metal around the valve stem. Gonna have to file that so it isn't so sharp. **However, it would be great to find a rubber grommet that I could put around the tube stem as it goes through the rim. Of course I will have to drill out the rim but I can do that. Anyone here ever used a grommet or something like that to protect the tube valve stem (from getting cut) as it transitions to through the rim from inside to out?

when the two 4.80-12 tires are on,
Sorry, I was not paying attention to that part :( :( I cant believe a local tire store cant take those tires off for you. Do you have an RV / Trailer dealer nearby ? Where are you located ?

As far as the valve stem goes I know you already have the tubes but I always try to get tubes with metal valve stems exactly for that reason.

I can't believe tire place can't remove tire also. Look for another tire place?

After a lot of work, I got a small tire dismounted by letting air out, then putting tire and wheel in vise. I placed the tire so that the wheel part was just missing the vise jaws and cranked on it. I would rotate the wheel to a different place if it didn't want to release. When you get to the part about putting tube in, be careful and don't puncture the tube with the large screwdriver you are using for a tire tool.

Harbor Freight has a manual small tire machine for around $50. I have one I use for lawn tractor tires.

No idea if it's safe or not but have seen videos with guys laying tire on driveway, placing a long 2x6 or 2x8 on tire up to the rim and driving their car onto the plank. Seemed to break beads (on vehicle sized) tires very easily.

ETA here I a video this guy also does it with a scissor jack at end.

Post your location. There's a lot of people here who could probably help you out, either getting the tire dismounted or making/modifying a wheel or hub to fit.

If their rim clamp machines can't go that small, then they really can't. My experience with that sort of wheel, and I guess everybody can agree, is that it's not a safety rim and the real problem is it comes off by itself. FWIW. I don't know how far you'd have to do this, but I would think if the tires are flat and you just take off through the yard towing the trailer, the tires will remove themselves?

I just had to re-mount one to mow the first time. Needed 4 hands. Luckily it was still stuck on one side, or else I'd probably be there yet.

the board trick will easily bring it. Drive your car up on the board if you need to.

Princess Auto here in Canada stocks the parts you need for the conversion you mentioned:
https://www.princessauto.com/sprockets-and-chains/category/420-020-035-000 select the "hub that is most suitable.
I'd bet that Northern Tools carries similar, The best [$ wise] is to continue pursuing using the tubes you have. The techniques described above have served many of us well, and as mentioned HF, NT, & PA, sell (or did), small tire tools. If all else fails small engine/agricultural shop, will have what you need either way.

There are things called 'valve collars' available for this situation, should you decide to enlarge the hole to remove the sharp edge, e.g.

Thanks everyone! The local tire store is owned by a family and I actually got 1 of the sons to say he would give it a try. My son said he still thinks we should just buy a couple hubs and then get some new tires & rims - I told him I wouldn't stop him - then he saw the cost. (not a good investment on an old garden cart). To answer a question here: yes, we broke the beads on both sides of the tire(s) but it's been extremely difficult to get the tire spoon inside the rim and under the tire to lift it up above the rim. It's raining pretty hard in in California so this can wait. But I will keep you folks posted. And thanks again everyone!

Thanks everyone! Since the garden Cart in question is still usable for hauling junk around, it's worth some repair dollars. But being on a pretty tight income, and considering how often the cart gets use (not that often), I was hoping to do this without purchasing hubs. I do have a question though: I know that whether or not I use the existing wheels with the integrated hub(s), or purchase new ones as suggested by "tdkkart', the bearings need to be packed. What about the void in the center of the HUB? I've seen a couple of video's where they just grease the spindle and the bearings, and others where they pack the entire cavity (in the center) between the bearing with grease?? I have no problem doing either - just wondering if it's necessary.
