The weight of the wheel and tire should be balanced evenly around the axle. Even a tiny difference in balance- less than an ounce - can create vibration in a tire that's turning hundreds of times per minute. And when you multiply by 4 or more wheels, it adds up.
Included in your service:
- Remove the wheels
- Remove the old tires from the wheels
- Check the wheels
- Mount and seal the new tires
