How much weight can this tire carry?

Load index 126 means one tire is rated to carry up to 3,748 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 Q speed rating mean?

It certifies the tire for sustained speeds up to 99 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 F?

Load range is the tire’s strength class, carried over from the old ply-rating system. This tire is F (12 ply), 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?

No. This is a standard tire, so a spare or repair kit is needed if you lose pressure.

Will LT35X13.50R20 fit my vehicle?

It fits any vehicle that specifies LT35X13.50R20, provided the load index and speed rating meet or exceed the original fitment. Check the placard inside your driver’s door, or contact us before ordering if you are unsure.

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.: TERRA FORCE RTX R/T

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.: 126

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
