Also, if it helps, Tractordata lists 11.2-24, but I have 12.4-24 on rear, and they work fine, try searching 12.4-24 r-3 tires.
I found these, 13.6-24 Titan Torc Trac TL R-3 tires, 4 ply. No idea price, and I can't swear they will fit.
Nvm, found it: Carlisle 11.2-24 Turf Pro 6-ply, $385 each, Miller Tire (online store, don't know how to link from phone).
I did some search on fronts, 5.00-15 tires=27.3" tall, and wow, 5" wide...
205/75r15 trailer tires=27.1" tall, and 8.03" wide, some they may or may not physically fit your steer components, and may or may not seat on your rims, but height is perfect.
Is there a reason 5.00-15 3-ribs wont work for you, mine don't damage lawm unless I turn sharp, but turfs will too
