Sounds like the bearing retainer nut is too tight.
Jack up one side.
With one hand on the front of the tire, and the other hand on the rear of the tire, see if there is a little slop when you try to push the tire in and out, or if you wish, wiggle the tire.
If not, then that says the retainer nut is too tight.
The proper way, is to tighten the nut gently, then back off until the cotter pin holes line up. Check to see if there is a little slop. If not, then back up one more hole and check again.
Since metal expands with heat, bearing retainer nuts should never be tight. If they are, they will very quickly over heat, and usually discolor, telling you that the bearing is ruined.
If any of the bearings are discolored, replace them, immediately.
