Replaced tires on this vehicle approx. every 12 to 18 months. Tried all kinds of brands, spent a ton of money...this car eats tires...

My Mazda will never stay aligned. I have had to replace tires every 3years due to uneven wear and cupping. True - I do not balance and rotate every 5K miles, but I have never had problems like this before. I have owned 6 other vehicles and never had the tire problems like I do with this vehicle. I had to give up on the alignment; the car just wants to pull to the right. It is usually OK for 2months after alignment, but then always worsens with time.
