Had issues on a Sunflower 6433-43 finisher with 12.5x15 tires  Tried type of tire...American Farmer because they were 20 ply...pure crap. DOT rated Firestones Same problem with any 12.5x15 only rated at 4700 lbs. On 4 tires way overloaded in transport. Bought the replacement tire from Genesco. Reasonable and the Genesco people were good to work with. Tires were like 28 ply and rated 225 mph. Thought good, should be fine behind the old Farmall. The tires performed well. Never had a flat and Gensco put sealer in them. THE downside, they are rated at 225 mph but only a very short time. In transport they REALLY build heat. One spring we got rained out at a distant farm. we continued planting ending at the other end. We had to travel about 30 miles and it was later in the spring and warm. We blew 3 of the 4 tires.

We have another Sunflower finisher with 355/60R16.5 (IIRC)  A Goodyear radial tire, has plenty of capacity but are 800.00 ea  We have some of those Firestone AD 2 implement tires  They seem the way to go. Capacity we need, will fit 10x15 rims, radial and a meaty looking tire. As the Genesco's fail we have been replacing them with AD 2  We are probably going to sell the Goodyears and rims and replace them with the AD 2 to standardize

Noticed the 12.5x15 replacement wasn't on the page  IF 320/70R 15  6150 lbs. @ 40 mph. Around 300.00
