I only buy Michelin. Have you ever tried to cut a Michelin tire in two? The bead was impossible to cut while the Goodyear tire was sliced like butter.
What brand and model of tires do you use? Are you 100% certain they are not made in China and do not use Chinese materials?
Do you know the number of Firestone, Bridgestone, Goodyear, Cooper, BF Goodrich, and Michelin tires that come out of China every day? And millions run on US streets every day, at speed.
IMO, this is a safety issue first and foremost.
What about the Bridgestone/Firestone tire recall that resulted in deaths, from tires made in Decatur, IL? Should we ban US tires too, since it's a safety issue?
People have to look to the DESIGN of the tire and the QC applied; you have crap engineering and crap QC in the US, Germany, China. You have state-of-the-art engineering and class-leading QC in the US, Germany, and China. You get what you pay for, the "Made In China" label is no guarantee of any quality label.
People need to understand that most of the products shipping from China were designed by US or European engineers, and the QC departments were set up by US or European companies. How well they function is NOT a result of China, but the level of oversight of those same US and European companies. Half my job here is providing QC oversight; yes, it costs my clients a bit more, but they get rock-solid quality products.
Ultimately, the problem isn't where it's made; it's who (which company) makes it, and what they are willing to skimp on. We need look no further than the recall of deadly Firestone/Bridgestone tires made in Decatur, IL for proof-positive of that.
