Let me try Sue...

Her 4 mounted Cooper Zeons are 60 lbs. heavier than the 4 stock tires - that's 15 lbs. per corner. Notice she typed "29 lbs wheel, 49 lbs tire" (singular) in her original post, NOT "29 lbs wheels, 49 lbs tires" plural as I think you keep reading it. The second set of numbers (29+49) is for the spare ONLY.
