Tire Tread/belt problems of the 2004 Suzuki Aerio

I own a 2004 Suzuki Aerio awd. The car seemed on the brink of hydroplaning at low rates of speed. At 14,000 miles the rear tires were completely bald and I purchased 4 new tires. The dealership attributed this to lack of rotation. Local tire shops stated this is a common problem with this model car. A full alignment was performed and regular rotation recommended. I had the car aligned and tires rotated every 5,00 miles. Again, I purchased 4 new tires at 42,000 miles after sliding off the road at a low rate of speed (less than 10 mph) and into a curb. The conditions were slippery and snowy. At 50,000 miles, I had my car inspected and a tire is starting to wear on the outside rim at an unusual rate. This compromises the belt and traction of the tires. This car is a major hazard because it may not even able to go 12 months between inspections or 3 months between oil changes without tires going bald or blowing out. There has to be a design flaw causing the tires to wear at unusually high rates: either the tire size or surrounding structures. I contacted the manufacturer and they were not able to provide a solution. I would have purchased a safer car but cannot financially do so at this time. The car has not had any other problems accept a few cosmetic issues. Please review this claim.

- contact bought the 2004 Suzuki Aerio in March 2004, and at the time of the purchase the vehicle had yokohama tires. At 12,000 miles all 4 tires had to be replaced because the tread was wearing out. The contact thought that the tires were faulty so she replaced them with 4 new michelin tires. At 14,000 miles the tread was wearing out on all 4 tires. The contact took vehicle to the dealership, and they stated that the vehicle needed a rear alignment, and that they would also replace all the tires. They replaced all 4 tires with michelin tires, and at 12,000 miles the contact took ehicle to the dealership, and they stated that both rear tires needed to be replaced. The current mileage was 48000.
