They may or may not drive out. I bought my white SC after sitting for 4-5 years. When I started on my way home, it felt like the tires were square, and they didn't get any better. I made it about 50 miles before I pulled into the first Discount Tire store and got them replaced. It drove like a new car. I had a 1200 mile trip ahead of me, so I couldn't do the flat tire thing!
Good Luck,
JD
