Choosing a passenger chain
A passenger snow chain works on the drive tires of a car, and its fit depends on the tire’s marked size. Metric, inch and LT formats all appear across the passenger range, so check the marking exactly rather than relying on a rough match. Numbers like 7-14 and HR78-15 describe different tire constructions, and each needs its own match.
Passenger chains do most of their work during winter driving. They reduce slipping on packed snow and ice, but they are not meant for long highway runs on bare pavement. Clean and dry the chain after each use, and replace links that have bent or cracked, because a failed link can damage the wheel well.
- Match LT and C markings exactly
- Keep speeds modest with chains fitted
- Inspect links and connectors after each trip

Vehicle fitment
Tire size decides fit. Read the size on each tire’s sidewall and match it exactly to the size table, including any LT or C marking. 215-14C and 215-15 are separate sizes, so near matches are not the same fit.
Fit is by tire size only, with no vehicle make, model or year involved. Confirm the vehicle year, model and trim separately before buying.
