Show full summary
It would also update related tax-code references and clarify the definition of highway tires to exclude tires used only on mobile machinery.
- Families and fleet buyers: Lowers purchase prices for new trailers and trucks, removing a tax that has added about $7,000 to trailers and $20,000 to clean diesel trucks.
- Truck manufacturers and dealers: Reduces a price barrier that the bill says raised costs for advanced engine trucks by as much as $50,000 and could help replace aging Class 8 trucks that are often more than 10 years old.
- Tax administration: Strikes the excise tax from multiple code sections and makes conforming edits, including a mobile machinery tire exception, to align other tax provisions.

No tire tax for mobile machinery
If enacted, tires used only on mobile machinery would be excluded from highway-vehicle tire excise rules. The machine must meet three tests to qualify. It must have equipment permanently mounted for work like construction or farming. The chassis is designed only to carry and power that equipment. It cannot carry other loads without major changes. This would apply to sales and installations on or after the bill's introduction date. Owners and makers of qualifying equipment could pay less tax or file less paperwork.
Repeal 12% tax on heavy trucks and trailers
