One thing I hate is that if I get it serviced and they have to take the wheels off they put the bolts back on so tight I can't crack them to get the wheel off if I had a flat.
What I do is after I get home pull the wheels off the car and put them back on again (with hubby's help) without using an air wrench on the bolts so I can get them off if I have to. They're still on tight, just not impossible.

You must be the only one left that actually changes a flat. Most people just drive to the nearest station with the flat on the car.
