How do you swap tires with 1 jack ? It's too much work. I'd rather pay the $5 extra.[/quote]
You pull out the spare (good time to check it), remove the right rear, put on the spare, rr to rf, rf to lr, lr to lf, lf to rr (or to spare if you're doing 5 tire rotation). This is for rear wheel drive. Adjust the air and you're set.
Oil changes and tire rotation are about more than the obvious. Every couple of months you spend a day with your car, checking it out and performing other maintenance items. There's always something to do.
