What is a Type S chain?Updated 9 months ago

Class “S” is a minimum clearance requirement set by some vehicle manufacturers. To determine if your vehicle requires Class “S” tire chains, refer to your vehicle owners manual (usually listed under “tire chains” or “snow chains”) or contact the vehicle manufacturer directly.

SAE Type S tire chains are designed for vehicles with limited clearance around the tires. These chains meet the standards set by the Society of Automotive Engineers (SAE) for minimal operating space. Specifically, SAE Type S chains are intended for passenger vehicles with restricted wheel well clearances, ensuring they fit without damaging the vehicle.

Key Features of SAE Type S Tire Chains:

1. Low Profile: Designed to sit low on the tire, reducing the risk of contact with the wheel well or other vehicle components.
2. Compatibility: Suitable for vehicles with minimal tire-to-vehicle clearance, including some cars, SUVs, and light trucks.
3. Ease of Installation: Often designed for easier installation and removal, considering the tighter spaces they are used in.
4. Reduced Risk of Damage: Minimize the risk of damage to the vehicle’s bodywork, brakes, or suspension components due to their compact design.

When to Use SAE Type S Tire Chains:

• Vehicles with Limited Clearance: If your vehicle has low clearance between the tire and the wheel well or suspension components, SAE Type S chains are likely required.
• Compliance with Vehicle Manufacturer Recommendations: Many vehicle manufacturers specify the use of SAE Type S chains to avoid damage and ensure safe operation.
• Driving in Snow and Ice: These chains provide necessary traction for driving in snowy or icy conditions while accommodating the space constraints of modern vehicles.

Before purchasing tire chains, it’s important to check your vehicle’s owner manual for any specific recommendations or restrictions regarding the use of tire chains.
