Overview
The SCC Security Chain Wide Base Link LT SUV/LT snow chains, part number QG3227CAM, are wide base link-style traction chains for LT SUV and light truck tires. The size list includes metric, LT and inch-format entries such as 345/55-17, 315/40-19 and 32×11.50-15LT.
SCC’s traction range includes cable and link styles, and this wide base link model is marked CAM in its title. It is a separate part from the QG3829, which has its own size list.

Wide base design on the road
A wide base chain spreads its contact across more of the tread than a standard link pattern. That helps it sit evenly on wide tires, where a narrow chain can ride unevenly or shift. The design suits LT SUV and light truck tires with a broad footprint, though the tire size remains the deciding factor for fit.
Careful installation matters more with a wide base chain. Position it squarely on the drive tire, tighten it fully, and drive a short distance before re-checking. Watch for twisted cross chains or loose hooks, and inspect the base after each trip, since uneven wear can point to a poorly sized chain.
- Fit the chain squarely before moving
- Check hooks and tensioners after the first drive
- Store flat or hung so the base keeps its shape
