What does the size 285/35R20 mean?

Reading left to right: 285 is the section width in millimetres, 35 is the sidewall height as a percentage of that width, and the tire mounts on a 20-inch wheel. All three must match what your vehicle specifies.

How much weight can this tire carry?

Load index 100 means one tire is rated to carry up to 1,764 lbs at its recommended inflation pressure. Check the placard inside your driver’s door and never fit a lower index than it lists.

What does the W speed rating mean?

It certifies the tire for sustained speeds up to 168 mph under standard test conditions. Do not fit a rating below your vehicle’s original specification. Always drive within posted limits.

What is load range SL?

Load range is the tire’s strength class, carried over from the old ply-rating system. This tire is SL, which determines how much weight it carries at a given inflation pressure.

Is this tire suitable for year-round use?

It is an all-season tire, built for dry, wet and light winter conditions. All-season tires are not a substitute for dedicated winter tires in severe snow or ice.

Does this tire have run-flat capability?

Yes. A reinforced sidewall allows limited driving after a loss of pressure. Fit only to a vehicle equipped with TPMS.

Specifications

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.: SP SPORT A/S DSST RUN FLAT DOT
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.: W (Up to 168 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.: 100
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.: All-Season
WeightWhat a single tire weighs. It doesn't change your price — delivery is quoted at checkout, not charged by weight.: 32 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
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.: Yes
WidthSection width in millimetres — the tire's width from sidewall to sidewall. It's the first number in a size like 225/65R17.: 285 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.: 35
Rim DiameterThe wheel diameter this tire mounts on, in inches. This one has to match your wheel exactly.: 20"
Part number: 265039946
