Radartires.com - a new(ish) company, based in Singapore. Sold at a variety of discount stores, they offer a wide range of tires that tend to be less than other brands. Generally the reviews I have read have been positive, considering for the fact that they are not high end tires.
It looks like they also manufacture the well-known Guardsman brand sold by Sears (based on warranty information) and have good mileage warranties on their products given the price point. They also have drivers in several well-known off road racing series.
