Do I need 2 chains or 4?

The number of tire chains you need depends on your vehicle's drivetrain configuration and your intended use. Here are a few scenarios to consider:

1. Front-Wheel Drive (FWD) Vehicle: If you have a front-wheel drive vehicle, you generally need only one pair of tire chains. The chains should be installed on the two front tires, which provide the power and traction for the vehicle.

2. Rear-Wheel Drive (RWD) Vehicle: For a rear-wheel drive vehicle, you also typically need one pair of chains. In this case, the chains should be installed on the rear tires to enhance traction and improve stability.

3. All-Wheel Drive (AWD) Vehicle: In an all-wheel drive vehicle, it's recommended to use one pair of chains on either the front or rear tires. This helps maintain balanced traction and prevents handling imbalances that can occur with different grip levels on the front and rear axles. However, consult your vehicle's owner's manual for any specific recommendations or restrictions regarding the use of tire chains with AWD systems.

4. Dual Rear-Wheel Axle Vehicle: Certain vehicles, such as some trucks or vans with dual rear-wheel axles, require two pairs of chains. Each pair should be installed on the tires of the dual rear wheels to ensure proper traction and stability.

Also, how much traction are you looking for? Chaining 2 wheels compared to all 4 is a significant difference in traction. 


Remember to check the manufacturer's recommendations for your specific tire chain model and consult local regulations regarding the usage of tire chains.

In summary, most vehicles typically require one pair of chains, but there are exceptions based on drivetrain configuration and vehicle type. It's important to follow the guidelines provided by the vehicle manufacturer and ensure proper installation and fitment of the tire chains for optimal traction and safety.
