Matching Chain Size To Tire Size
Chains come in different sizes to fit tire widths and diameters. Using the wrong size can cause damage or poor performance.
Check your tire sidewall for size numbers. Match these numbers with the chain size guide from the chain maker.
- Tire width (e.g., 205 mm)
- Aspect ratio (e.g., 55)
- Wheel diameter (e.g., 16 inches)
Considering Vehicle Type
Different vehicles need different chains. Light cars, SUVs, and trucks have different weight and clearance needs.
Check your vehicle manual for chain rules. Some cars have limited space near tires and need low-profile chains.
- Light cars usually fit standard chains
- SUVs may need heavy-duty or reinforced chains
- Trucks often require larger, stronger chains
- Some vehicles with ABS or traction control need special chains
Evaluating Road Conditions
Your usual driving roads affect chain choice. Deep snow, ice, or mixed conditions call for different chains.
Choose chains based on how often and where you drive. Some chains are better for icy roads, others for thick snow.
- Diamond pattern chains offer good grip on ice
- Ladder style chains work well in deep snow
- Cable chains are lighter and easier to install
- Studded chains provide extra traction on ice
