Parts & Accessories Rounds Peace, mercy, and blessings of God be upon you. I have stone tires, size 285/70/17. Their type is Nankang, made in Taiwan. Their date is 22. I bought them and used them for 3 months, then removed them and stored them in the warehouse. They were not exposed to sun or anything. The tires are good, still with their seals and blue writings, and still with their tread. The price is by auction, and the sale is easy.
