From a units perspective:
- Passenger tire imports rose 10.4 percent (14.7 million units) to 155.9 million units;
- Light truck tire imports grew 19.8 percent (5.53 million units) to 33.4 million units; and
- Medium truck/bus tire imports shot up 31.8 percent (4.18 million units) to 17.3 million units.
As such, imports represented 69 percent, 87 percent and 76 percent of U.S. passenger, light truck and medium/heavy truck tire shipments, respectively, last year, according to Tire Business' analysis of the USTMA and Commerce Department data.
Roughly two-thirds of passenger tire imports, however, are estimated to be tire brands affiliated with companies that have captive manufacturing in the U.S., so the "true" passenger tire import share would be closer to 23 percent.
Thailand continues to be the No. 1 source of imported tires for the U.S., being ranked first in the three main categories by comfortable margins over the No. 2 exporting nations despite reduced shipments last year versus 2020, the Commerce Department data show.
Mexico was the rising star among trading nations, registering 52.8 percent and 55.9 percent gains in exports to the U.S in passenger and light truck tires, respectively.
Taiwan—whose tire makers were hit the hardest by the U.S.'s imposition of elevated import duties early in 2021 — was the most notable at the other end of the spectrum, shipping 56.5 percent fewer passenger and 59.4 percent fewer light truck tires to the U.S. last year versus 2020.
