Fuel Saving Tips
Removing weight increases fuel mileage. Your spare tire weighs a lot. You can temporarily seal and inflate a punctured tire with a can of Fix-A-Flat. You can then either return home and put on your spare, or drive to an auto shop and get your tire patched. Assuming removing the spare tire saves 0.25 - 0.5 MPG, the can (~$10) would pay for itself in about 4-8000 miles. Not the best return on investment, but not bad either.
