The Chinese tariff, as in all tariffs, is hard to comprehend. Tire Business Magazine has feature articles on this topic and follows this topic. If you sell tires, I would highly recommend subscribing to this publication. Here’s the link: http://www.tirebusiness.com/
From what I understand, the U.S. could only impose a three-year tariff without compensating China. Plus, all the tire companies have been gearing up the past three years and have found ways to be competitive, once the tariffs are lifted.
The tariff situation is complicated. There were many, like the Tire Industry Association (TIA) that opposed the tariffs. And, if look back on the last three years, the tariff may have curbed tires from China, but imports from Korea, Indonesia and Thailand increased. I have not read anyway the overall effects of the tariff, but to be honest, it may above my pay grade to understand it in full.
Some say tire prices will drop as the supply increase. Also, buying groups stockpiled tires during the tariff period, which will also cause tire prices to decrease, in theory at least.
I think we need to remember that during this period we had an economy where fewer cars were built, less new cars were purchased and less miles were driven by the motoring public. And, as the economy improves so will the demand for tires.
As far as that notice you got about the lesser price of the Chinese tires, I have yet to hear from my tire distributor. I sell a lot of tires and will forward any information I receive.
