The tires made in China these days will surprise you... virtually ALL the major mfr's now participate in China,... yes.. even Michelin (according to Discount Tire).
The tires made in China prior to 2011 were more suspect, but DOT and US mfr's have been closely supervising quality control in the last 5 years and although there is doubtless some "off brands"...the major-branded tires are now better regarded since the DOT banned several lines from import.
(Marathon load range E are still not allowed from China, however. Only load range D, according to Discount.... who told me they have dropped the Marathon line entirely when stock is sold out. They now promote Maxxis, Carlisle, and Heartland, and were pretty confident....but the articles I"ve read were only confident in China-produced tires that carry major brand names...no "off-brand", and as far as I'm concerned, Heartland is an off-brand, however the tire I saw in the showroom looked well-made.) I bought the Carlisle Trail HD's which are the latest/greatest from that mfr'r, and keep detailed records on use and storage, etc. I'll post any developments.
