Senate Bill Targeting Consumer Tires Stalls

Feb. 14, 2024

Senate Bill 6304, which would have set consumer tire rolling resistance regulations in Washington State, is “dead,” according to the U.S. Tire Manufacturers Association and the Tire Industry Association.

The Washington Senate adjourned on Feb. 13 without taking action on the bill, representatives from both associations confirmed.

If passed, Senate Bill 6304 would have established and enforced “energy efficiency standards for replacement tires” sold in the state.

House Bill 2262, a piece of proposed legislation that sought the same objective, failed to exit committee on Feb. 6. (Click here to read MTD’s report.)

In addition to rolling resistance standards, Senate Bill 6304 also called for:

  • The creation of a database of replacement tires offered for sale or distribution in the State of Washington;
  • “Requirements for any tire brand name owners and tire manufacturers with replacement tires in production offered for sale or distribution in the state to report information” to state officials;
  • Establishment of a rating system that would denote the energy efficiency of replacement tires “based on their rolling resistance coefficient,” with ratings displayed for consumers at the point of sale, and;
  • Establishment of testing procedures “in alignment with enacted regulations by the National Highway Traffic Transportation Safety Administration.”

The bill also would give the state’s Department of Commerce the ability to prohibit the sale of replacement tires that do not meet minimum energy efficiency standards mandated by legislators.
