The choice between 2-link and 4-link spacing in tire chains depends on the specific conditions and preferences. Here are some considerations for each:

2-Link Spacing:
- Enhanced Traction: 2-link spacing chains typically provide more contact points with the road surface, resulting in increased traction and grip. This can be beneficial in severe winter conditions or on icy surfaces.
- Aggressive Performance: The closer spacing of the chain links allows for a more aggressive and robust performance, especially in challenging terrains.

- Smoother Ride: 2-link spacing chains offer a smoother ride compared to 4-link spacing. The wider spacing between the chains reduces noise, vibration, and potential damage to road surfaces, making them more suitable for driving on regular pavement.

- Versatility: 2-link spacing chains are generally more versatile and can handle a wider range of conditions, from light snow to moderate winter driving.  

4-Link Spacing:

-Ease of Installation: The wider spacing can make the installation and removal of the chains slightly easier compared to chains with closer spacing.

Ultimately, the best choice depends on the specific road and weather conditions you anticipate encountering, as well as your preferences for traction, ride comfort, and the intended use of the chains. It's always a good idea to consult the manufacturer's recommendations and guidelines for the particular tire chain model you are considering, as they may provide specific insights based on their design and intended usage.

In short, if you are looking for overall best traction and performance you would go with the 2-link spacing.
