Where did you get these tires? I have never heard of them, nor have I heard of the Cordovan Centron. As far as I know, the Regatta 2 was a Walmart exclusive. I would say that, if they are sold here in the US, they are probably reasonably safe and have met safety standards. If you are concerned about safety, you should do research before you buy. Tires are a big safety component on your car, right up there with the brakes and steering (these things are often overlooked, though, and don’t seem to be much of a concern for some people, as long as the car will start and drive. I’m glad you are concerned about your tires). It also is a good idea to buy from a known reputable company. Some of the best, in my opinion, are Michelin, BFGoodrich, Bridgestone/Firestone, and General. Goodyear makes a good tire as well, but seem to have more structural issues than the others I mentioned.
