Do yourself a favor (like I did) and get yourself a small floorjack and a pair of jack stands and save yourself some grief. I have the jack tubes but like absolutley all of these cars- mine are rusting. I do NOT trust that they will not allow the car to shift if I am changning a tire on the side of a freeway, endangering me, my wife if she had to try to do this, and/or the underside of the car. So SAFETY FIRST spend $20 on a cheap pair of jacks stands, and $30 on a cheap floor jack from your "local importer of chinese tools" freight, and thank yourself for having them the FIRST time you have to swap a tire on your car. Not joking here Having changed the tires on the 190 a few times now, I can't even imagine the nightmare it would have been without my cheapo floor jack and jack stands (which stay in the trunk always!)
