Quick answer: Super Z tire-chain fitment must be matched to the tire size printed on the sidewall and the vehicle owner’s manual clearance rules. Use the chart below as a reference, then verify the current Peerless/SCC fitment lookup and pre-fit the chains before driving in snow.

Before Using The Super Z Size Chart

• Confirm the exact tire size on the tire sidewall, not only the vehicle trim.
• Check whether the owner’s manual allows chains, cable chains, or Class S low-clearance chains.
• Pre-fit chains at home before using them in weather.
• Do not use chains on modified tire/wheel sizes without checking clearance.

Super z tire chains are some of the best snow chains on the market. They are extremely strong, reliable and they can be installed on any wheel. But, they are available in different sizes. Those sizes are Z539, Z547 and many others. In fact, there are 8 different sizes available. Which one suits your vehicle? To find out, take a look at the chart below. We were able to contact Security Chain Company and to get the answers directly from authorized personnel. The chart starts with the smallest tires and increases to the maximum size available. For each row you can see the model of the chain that suits the best and the one that should be used. The Z539 or similar is the model of the chain and as we have mentioned, there are several variations. By using the correct chain, you ensure better and safer drive in a case of snow and ice.

Source Notes

Super Z fitment guidance was checked against the Peerless tire chain finder, Peerless Super Z6 product guidance, and SCC/Peerless application charts. Fitment can change by tire size, vehicle clearance, and product line, so current manufacturer lookup and the vehicle manual control.
