Disc Brakes, Tires, and Wheels for Timbren 5,200 Pound Axle-Less Trailer Suspension System
Question:
I am looking at replacing an existing triple axle Two 3500# axles and one 2000# axlesystem on a heavy pontoon trailer with a double axle system with two 5200# axles. What is the smallest diameter wheel I can use with this axle and still use disc brakes? I need to stay as low as possible for shallow water boat access.

Expert Reply:
For 5,200 pound axles such as # ASR5200S04 I recommend disc brake kit # K2HR526D which will accept wheels as small as 15 inches. Only certain kits with certain bearing sizes will fit the spindles on the axle-less systems so 15 is as small as you can go.
That means a 225/75-15 tire and wheel combo, see link. This size has an outer diameter of 28.4 inches. For a tire and wheel in this size that has a higher enough capacity for 5,200 pound axles I recommend # AM32680 rated for 2,830 pounds at 80 psi.
For each of the disc brake kits you will also need 2 inner bearings # 25580, 2 outer bearings # 15123, and 2 grease seals # RG06-090 (these seals are sold in pairs).
