My CFO would have something to say if I were buying five sets of tires a year!
My wife doesn't mind me buying tires when I save about $300 a month riding the C14 to work instead of driving the Expedition that gets about 10 mpg. But I do end up buying a new rear every month and a half to two months and I replace the front every other time.
@ Bagger: yes I do spend a lot of time out riding the great roads here in the Ozarks, I just need to get my bike put back together since I am starting to have withdrawls.
