Tire Sidewall Problems of Mitsubishi Diamante

Tires extremely noisy since about 2,000 miles. Tires severely cupped after 5/6,000 miles. Ride extremely loud, with great deal of vibration. Since about 12,000 miles, extreme cupping of all four tires plainly visible. Tires at all times at mitshubishi recommended pressure, and rotated every 5,000 miles. No impact damage to any tire, or rim. No scuffing of sidewalls, or punctures. Tires apparently cupped from the start. Car purchased new, with 3 miles. Dealer cannot explain cause for severe cupping, but refuses to replace tires. Also contacted Mitsubishi motor, who tells me that they have had some complaints on these tires. No one seems to want to accept responsibility. Concerned that tires may suddenly fail, ES they are severely cupped (all 4) and ride with great deal of noise and vibration. Dealer claims problem not with auto, since properly aligned. Tires are balanced, and at proper inflation. Now becoming concerned for safety, and upset that dealer and Mitsubishi doing nothing to correct condition. (dot number: tox82jm250 tiresize: p215/60r16).
