Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Once all of the lug nuts are off, there is nothing holding the tire/rim in place. Most commonly, it's just stuck on there due to time/build-up/weather/etc. With the lug nuts removed and the wheel off the ground, use a solid, rubber mallet/hammer (or equivalent) and tap the rim/tire from behind. Turn the rim 1/4 turn and tap again. Repeat until the rim pops free.
