WANDA Trailer Tire Wheel Assembly 20.5×8-10 (5 Lug) White Rim
Features include a 10-ply rated construction with load range E and a load index of 95. The wheel uses a 5-lug on a 4.5″ bolt pattern and is finished in white. Speed rating is L (up to 75 mph) for highway use. Best for boat and motorcycle trailers that require a reliable 5-lug arrangement and strong load capacity.

Caution: larger wheel size may require braking or suspension clearance checks on smaller trailer frames.

Buying Guide: Key Purchase Considerations

- Maintenance needs: Inflatable tires require regular pressure checks; check wheel bearings and brake clearance where applicable.
- Fenders and protection: Fender choices affect debris protection and splash management; ensure compatibility with wheel diameter and mounting points.
