More on tires, my 2001 Dutch Star has the original tires still. They have always been covered and look like new . Have 56k miles on them. I run them hard (inflation) and am very particular about checking air pressure before embarking on any trip. I have never had a problem but I know I am probably reaching the life cycle end . Any recommendations on where to buy tires here in the southeast? These 275/80 22.5 tires are 9 years old and I hate to throw them away, also my coach runs several thousand lbs lighter then gross. $500.00 bucks apiece times 6 tires :question:
