Duals really help you get more rubber on the ground. However, if you routinely cut in wet conditions and your soil is sticky, it is very difficult to keep the mud from building up between the duals, no matter how far apart they are. For those situations, a large single tire is the way to go. For large singles, you have two good 32 rim options: a 36 wide rim that is used with the 73x44-32 tire, and a 44 wide rim that is used with the 68x50-32 tire. If you are ordering a new machine, you should be able to specify either of these rims from the factory, or you might be able to find them used. If you have new rims custom made to fit your application, its not much $ compared to the tires. Now for the tires: for the 36 rim, the Michelin 1050_50 R32 is the way to go. It is a radial, supports a huge load at low pressure, and rides nice on the highway. That is what we are using on a 1680. If you have hilly land, you might not want to go this way because it is a very pliable tire, perhaps too pliable for steep sidehillsIJ For the 44 rim, Firestone has introduced a new tire size called the 76x50.0B32. Its a huge bias ply tire and is rated for higher loads than the Michelin. However, Firestone makes it difficult to determine the rated load at reduced pressure, so its hard to compare the two. e-mail me with the max weight you want to carry with the tire and I will try to calculate the rated pressure for the tire you are interested in. I have data from most of the manufacturers.
