Changing the Tires

It's been over 3 years since I got my tires replaced. I don't drive much, but my tires get worn out so easily. These days I'm a slow driver. Not by choice, but rather because of the car I drive. I just don't have the power. The up side is pretty high MPG. Since my car is a hybrid, supposedly the tires get worn out quicker because of the extra weight.

I don't know if the hybrid thing is really making a difference in money saved. With everything considered, I'm starting to consider not buying a hybrid in the future.
