AutoSock vs tire chains

Textile traction devices can be easier to fit, but acceptance and suitability vary by jurisdiction, vehicle and posted control.

What to know

Fitment safety

Follow the vehicle manual and the traction-device maker's exact fitment table. Install only on the axle positions they permit, stop if anything rubs, and respect the device's maximum speed.

Laws, agency guidance and device approvals can change. Verify before each trip. Roadside signs and law-enforcement direction control.
