You're welcome! You don't mean the tires are actually 20 years old, do you? If so be careful. Mine also had 20 year old tires with only a couple of miles on them. One had a belt blow out while sitting in the garage over the winter, it had a blister in the tread 10" long, 4" wide and 2" high and felt like I had a tennis ball strapped to the tire. Old tires are bad news, the rubber loses its flexibility and its grip on the radial plys.
