I went to America's Tire Company today to have them remove a screw that was stuck in my tire. They took a look at the tire and realized they were over 10 years old. They said they won't touch my tire due to liability issues since its so old. I have BF Goodrich A/T and they have plenty of tread on them.
Is there a way to remove the screw and patch the hole or are my tires too old and I should replace all four tires?
