Take the time once or twice a month to walk around your vehicle and look for:
Bulges, blisters, and other weak spots
Cracks in the sidewalls
Nails or other objects
Tread wear, especially uneven wear
In addition, make sure the tires are properly inflated. The recommended pressure can be found in your owner’s manual. Your fuel usage will increase if your tires don’t have the right amount of air in them.
