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.
- ST PRO
- 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.
- M (Up to 81 mph)
- 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.
- 132
- 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.
- 14PLY
- 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.
- All-Season
- WeightWhat a single tire weighs. It doesn't change your price — delivery is quoted at checkout, not charged by weight.
- 35 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.
- BW
- ConstructionHow the tire's internal plies are laid. Radial is the standard on virtually every modern passenger vehicle.
- Metric
- 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.
- No
- WidthSection width in millimetres — the tire's width from sidewall to sidewall. It's the first number in a size like 225/65R17.
- 235 mm
- Aspect RatioThe sidewall height as a percentage of the section width — the second number in 225/65R17. A lower number means a shorter sidewall.
- 85
- Rim DiameterThe wheel diameter this tire mounts on, in inches. This one has to match your wheel exactly.
- 16"
