I second the floor jack idea.  I've changed a lot of tires in 18 years patroling the highways.  I had several of the original equipment jacks fail at the most inoppertune time.  Then it's tow truck time.
The four way lug wrench makes a difficult job a little easier.
Basically I'm not a fan of the original equipment and doughnut spares. 
My 2 cents.
