Hi there. I have changed a tire or 2. I figured not too bad for a woman!!! Got my first flat tire last night and this morning was changing the tire on my 1996 Acura 3.2TL (premium). I did everything down to the tee and got to the part to take off the flat and it won't come off the car. The car is in park, hand brake set and on a smooth flat surface. My husband was impressed that I got that far. Any suggestions as to what I am doing wrong? Or should I get a tire sealant just so that I can make it to the repair shop?
