The backspacing of Taskmaster 15 x 5-Inch Steel Modular Trailer Wheel # 560550SM1 is 3-1/2-inches. I went to our warehouse and took this measurement for you.

Do note that the 3-1/2-inches is the wheel's backspacing. Once you mount a tire on the wheel there will be a change to the actual clearance between the tire and trailer frame. A 15 x 5 wheel like this can take either a 205/75-15 trailer tire or a 225/75-15 tire. The wider 225 size will have less actual clearance between the inside of the tire and the trailer frame.

This wheel carries a maximum load rating of 2830-lbs, so your total trailer gross weight, when divided by the number of wheels, should not exceed this amount. The tires you mount also need to be rated appropriately for the load.

Always keep trailer tires fully-inflated to their maximum psi pressure as noted on the tire sidewall.
