LT245/70R16 Cooper Discoverer AT3 4S – 3PMS All Terrain All Weather
The Cooper Discoverer AT3 4S is a comfortable on-road all-terrain tire designed for maximum grip in wet and snowy conditions while keeping its durability off-road. Patented saw-tooth technology and deep center grooves help reduce hydroplaning and increase snow traction. The Discoverer AT3 4S 5-Rib tread pattern provides great off-road capability and zig-zag siping increase biting edges for more stability and control. It also has a 95,000km tread life warranty for all sizes.
Carries the 3PMSF symbol — tested and rated for severe snow service.
What these tire specs mean
- Load index 118 means each tire can carry up to 1320 kg. Check your door jamb placard — the tire needs to meet or beat the load rating your manufacturer specifies.
- Speed rating R is the maximum sustained speed this tire is designed to handle under proper conditions. That works out to 170 km/h under correct load and inflation — not a target, just the rated ceiling.
- All Weather tires are built for year-round use — warm months and cold. They carry the 3PMS symbol, which means they qualify under Quebec’s mandatory winter tire law.
- 3PMS stands for Three Peak Mountain Snowflake — a symbol earned by meeting specific severe snow traction standards in testing. It is the mark Quebec requires for winter tire compliance.
- Vehicle type indicates the service category this tire is built for — passenger car, light truck, commercial, or other. Matching the right category matters for load capacity, handling, and safety.
- Warranty coverage is backed by the manufacturer and applies under normal use — regular rotations, correct inflation, and proper alignment. Keep maintenance records if you ever need to make a claim.

Worth noting on the spec side: this tire carries 3PMS certification for severe snow service, load index 118 and speed rating R (~170 km/h).
About the LT245/70R16 tire size
