Its probably one of those replica brands that sell with no warranty, but are essentially idential to, say, a Goodyear Eagle. My tires are the "Fuzion ZRi's" which I never heard of before, but they are just a re-named Firestone Firehawk Wide Oval, but at half the price (no warranty). Never heard of Linglong. Surely some research will yield some clues as to who makes them. I wouldn't be surprised that they are an econo Goodyear Eagle.
