I had 2 Hi-Run tires separate the same day about 300 miles apart. Damage on both sides if the trailer, each tire was on a different axle. Not even close to being overloaded, had certified weights done before trip, kept at 65 and under. Trailer was 3 months old and was just delivered to dealer when we purchased. Manufacturer fixed all the damage and paid for all new Goodyear tires including the spare.
