While the BT8 Bearing Kit part # BK1-100 does not come with a washer you would still need to use a washer like the part # 5-23. If you are having a hard time getting the nut to thread on with the washer installed you'd need make sure the inner bearing is all the way seated on the spindle and doesn't need to be installed further onto it. For more info on this I attached video that covers this as well.

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…
