Compact tractor rim/tire Q

I have a Ford 1320 that has R-1 tires. I want to get a set of R-3 turf tires on rims for mowing that I can swap out when I'm not using the loader. Seems harder and more expensive than I thought to find replacements. The rears use the same size for both R-1 and R-3. I found these:

Seems pricey but buying rim shells and making my own centers isn't much better.

Summit actually carries the tires.

Having trouble finding the front rims with 4 3/4 bolt circle and 3 inch pilot hole. The R-1 rims have 2 1/2 inch backspacing but are 12x5 and I need at least 14x6.
Anybody here deal much in this area of equipment?

I have a 1320, too. When I bought it, I got it with the turf tires. I have had to replace the front tires twice and I looked at the Carlisles. They appear to be much lighter than the original Firestones which are not exactly heavy duty. It takes some real hard looking, but the original Firestones were still available 4 years ago when I last bought them. If you can find them, they are a much better choice for our tractors than the Carlisles.

I may have to replace my front rims some day because they are severely rusted on the inside. I had to use a lot of bead sealer last tire change to get the bead to seal. I most certainly do not want to resort to tubes. I have tubes in the rear and they are a pain.

Hopefully someone could point us in the right direction for rims. I have calcium in my rears. Works great but a pain also.

One if these firms usually have any hard to find part for a tractor.

I have used these guys. They may have what you need but sometimes they are pretty pricey. Good luck!

Don't use Calcium. Our tractors' tires have beet juice in them. Rims don't rust. Plus it is environmentally friendly.

Well I ended up buying rim shells and tires from R.E. Miller. He told me no one in the states makes these rims for import tractors, which mine is a Yanmar.

I had plates cut out of 1/4 inch and turned the od/id. Then set them up in a cnc Bridgeport to drill the holes. Fortunately, I work in at machine/weld shop.

And the finished product. Wifey's happy it mows much better.

nice job you did on the wheels !

might think about having them blasted, JB weld the pits on bead area, sand smooth, and paint with a epoxy or urethane based paint. Another option, Check with you local powder coater.

I think it would be easier to cut the hoops off the centers and weld them in new hoops.
