The full spec sheet
- ModelThe manufacturer's name for this tread pattern. The same model in another size shares the same tread design and rubber compound.
- Discoverer True North
- Speed RatingA letter code for the highest sustained speed the tire is built to handle — T is 118 mph, H is 130, V is 149. Don't fit a rating lower than the one your vehicle came with.
- H
- Load IndexA code for the maximum weight one tire can carry at its recommended inflation pressure. Match or beat the index listed on your driver's-door sticker.
- 97
- Load RangeThe tire's strength class, carried over from the old ply-rating system. C, D and E carry progressively more weight at higher inflation pressures — you'll mostly see them on trucks and vans.
- SL
- SeasonThe conditions the tread and rubber compound are designed for. All-season is the year-round default; winter tires stay flexible below 45°F; summer tires grip best in warm, dry weather and aren't made for snow.
- Winter
- WeightWhat a single tire weighs. It doesn't change your price — delivery is quoted at checkout, not charged by weight.
- 29.76 lbs
- SidewallHow the lettering on the tire's outer wall is finished — blackwall, white letters, and so on. It's cosmetic and doesn't affect how the tire drives.
- BSW
- Run FlatA reinforced sidewall that lets you keep driving a limited distance at reduced speed after losing air. Only fit these to a vehicle with tire-pressure monitoring.
