well, odds are not many will know what wheels will work for you, due to well, its not that common a machine, and or way of getting tires for it
I think what you MIGHT be better off trying is, taking one tire./wheel off and taking it to a good tire shop that can measure things for you
which includes wheel size, lug bolt pattern and wheel OFF SET
as you will need to know all this info for finding an AUTO/ TRUCK tire wheel that would maybe work for you!
one of the most common issues I find when trying to match up truck wheels to s skid steer(as I know many have tried this0 is the hub hole on skid steers typically is larger than on auto/trucks
so like I said, a good tire shop can measure all things fort you and get you exact spec's,. from there, you can try contacting a GOOD aftermarket wheel shop ( that is if tire shop isn;'t willing to do so for you, as they might not want to invest the time needed to do so)
and give them your spec's and see what they recommend or can match up that will work for you
THAT or maybe just find a set of correct for your machine wheels and put the tires on you like?
used wheels can many times be found on ebay, craigslist, faceboomk market place, salvage yards and other places by doing online searches!
just keep in mind that many TRUCK tires don't have strong enough sidewalls for skid steer use, as there not designed for the way skid steers turn/skid!! which can cause them to come off the wheel or get damaged when using on a skid steer! E or F load rated would be what I'd be looking for, but might be hard to find in the size you mentioned!
