SCC Peerless Auto-Trac Light Truck/SUV Tire Chains - Self-Tightening

In this review of the SCC Peerless 0231705 Auto-Trac Light Truck/SUV Tire Traction Chain set, the bottom line is simple: these chains are best for drivers who need fast, reliable traction on snowy or icy roads and value an easy, self-tightening system that installs without jacking the vehicle. The standout reason to buy is the patented ratcheting tightening system that automatically tightens and centers the chain while driving, removing much of the fiddly work associated with traditional chains and making them a practical choice for mountain passes and winter travel.

Key Features

• Self-tightening ratchets: The worry-free ratchets provide automatic tightening and centering while driving, reducing the need to stop and readjust.
• Easy installation: AutoTrac can be installed without moving or jacking up the vehicle, allowing installation in minutes in cold conditions.
• Diamond pattern cross chain: The diamond pattern delivers a smoother ride and more consistent grip across the tread for improved traction on packed snow and ice.
• Low-mass cross members: Manganese alloy steel cross links are shorter and lighter, which reduces flyoff and increases the number of gripping points.
• No extra tensioners required: The patented system eliminates the need for additional chain tensioners, simplifying setup and reducing parts to manage.

Who It's For

The SCC Peerless Auto-Trac chains are ideal for SUV and light truck owners who frequently drive in winter mountain conditions and need a system that installs quickly and tightens itself during use. Drivers who value simplicity and a smoother ride compared with conventional ladder-style chains will appreciate the diamond cross pattern and automatic centering.

Those who should look elsewhere include drivers who need high-speed capability above 30 mph or who are unsure about exact sizing for their tires. Several users report mixed experiences with fit, so if precise sizing is essential, verify fitment carefully before relying on them for a long trip.

Pros & Cons

Pros

• Quick installation without jacking the vehicle makes roadside fitting far easier than traditional chains.
• The automatic self-tightening ratchets keep chains centered and reduce mid-trip adjustments.
• Diamond cross pattern and low-mass manganese links provide a smoother ride and reliable traction on ice and packed snow.
• Build quality is generally praised by customers for durability and ease of use.

Cons

• Sizing can be inconsistent for some users, with a few reports of chains fitting too tight; double-check compatibility for your tire size.
• Not designed for speeds above 30 mph, so longer highway stretches in winter require cautious planning.
