Tire change
If you really need to change it yourself, there are inexpensive "bottle" jacks available that can handle 3-10 tons for under $30. These type of jack are more difficult to place properly and safely so be aware. Depending upon which tire, sometimes you can use the inside rear tires to repair the outer tires but have your AAA number available if something goes awry. The majority of "leaf" jacks are limited to 1-2 tons so they may not meet your requirements.
