Shopping for tires is much more than "this size fits" you need to choose tread wear numbers that match your mileage expectations while getting a tread that will work with your typical road conditions, etc. If you buy the cheapest tires, or most expensive things dictate how long they will last beyond what the tire store tells you.

The OEM tires that came on my BRAND NEW aveo were bald (smooth) on all four corners in 3 months. I drove way to hard for the type of tire it was. I know it was the wrong tire because they put a new set on under warranty and they also only lasted 3 months until the cords were showing..
