Tires B7100 Tire Sizes

[Temblor]

I didn't look at all of them, but most of them seem to be 2-ply tires that are probably rears for small lawn and garden tractors. This would not be suitable for use with a loader on a B7100.

6ply, $57 ea, all in, on ebay here.. 20 5x8 0 10 LRC 205 65 10 LRC Trailer Tire Snowmobile Jet Ski Utility Boat | eBay

I want to resurrect this old thread because I need new tires for my B7100HST and I think I want R-4 tires.

Turf tire sizes are:
Front: 20.5x8.00-10
Rear: 29x12.00x15

I think a good R-4 Tire choice would be:
Front: 20x8.00-10
Rear: 27x12.5-15

Looking for confirmation of my conversion from Turf to R-4.

Also interested in where to buy these at a reasonable price. I'm finding that these are only available as skid-steer tires so far and the ones I've found are insanely expensive in my opinion.
Any suggestions on where I can find these sizes cheap (under $100 each ideally)? In 2015 when the last person posted on this thread, they offered an ebay price of $57 each. I don't see anywhere near that price anymore.

thanks!
