Troubleshooting

Wheel vibrates excessively at speed.

Check that the wheel nuts are tightened correctly and evenly. Ensure the tyre is properly seated on the rim. Consider having the wheel balanced if the issue persists.

Tyre loses pressure slowly.

Inspect the tyre bead for damage or debris. Check the valve stem for leaks. Ensure the rim is not corroded or damaged where the tyre seals.

Uneven tyre wear.

Verify correct tyre pressure is maintained. Check wheel alignment if applicable to your trailer setup. Ensure the trailer is not overloaded.

Difficulty mounting to hub.

Confirm your trailer hub has a 4 stud pattern with a 4-inch PCD. Ensure the centre bore of the wheel (67mm) is clear of obstructions.
