I was attempting to install winter wheels on my 2004 xc70. I had not previously changed a tire on this vehicle and was very impressed by the quality of the jack and the jack points on the underside of the vehicle. However, after raising the rear drivers side wheel and completely removing the five wheel bolts, I was unable to remove the wheel from the car. I was reluctant to apply a whole lot of force while the car was up on the jack and eventually gave up with mission not accomplished. Am I overlooking something? Any suggestions?
