No directional arrows or any writing this side in or out. Mount them anyway you want. If you get one that takes more than 2oz of weights or doesnt seem to balance. Have them to rotate the tire on the rim 180 degrees and rebalance it.
If the tire shop put them on the rims correctly. If they are not directional. No arrows. put them on any hub you want to. If there is an arrow on thhe side wall. Point the arrow forward.
