Expert Reply:

The modern equivalent to a 20.5x8-10 is going to be a 205/65-10. The bolt pattern is either going to be 4 on 4 inch or 5 on 4-1/2 inch. So if it requires 4 bolts then you likely have a 4 on 4 pattern. If it is 5 bolts then it is likely 5 on 4-1/2. To be sure you can use the help article I have linked that explains how to measure for bolt pattern.

For 10x6 inch wheels we have a few options. For a 4 on 4 bolt pattern we have white steel wheel # AM20041. For a galvanized version we have # AM20043.

For a 5 on 4-1/2 bolt pattern we have # AM20046 for a white steel wheel and # AM20048 for galvanized.
