My original post was posted late Tuesday afternoon. Tire Rack had estimated that the tire I ordered should arrive at my house in The Villages on Friday. Tonight (Wednesday night) the doorbell rang and the UPS driver had dropped off my new tire--only about 27 hours from when I placed the order.
I'm sure the major name tire dealer on 441 will be surprised when I show up tomorrow morning to have them mount and balance the new Michelin tire. It was only yesterday afternoon about 3:00 PM when they gave me the outrageous price--over $100 more than I paid Tire Rack--for the new tire.
Some days people can be very happy campers. Today is one of those days!
P.S. I didn't use either Costco or Tire Rack for the new golf cart tires, gemorc. Neither of them sell golf cart tires. But when I called Tire Rack to inquire, they referred me to another online store, Tires Unlimited
http://tiresunlimited.com/ Their prices for golf cart tires are very attractive. Later, I also found the Golf Cart Tire Store
http://www.golfcarttirestore.com/ They sell both golf cart tires and wheels at attractive prices.
