How did you judge the tires are halway thru their life? by miles or by tread depth?
BTW, a quick search on google says lots of tire shops with potentially used tires for sale. An actual used tire shop has much less standards than a retail store. They will mount anything that holds air on any rim that will hold a bead. Might be able to find a used michelin and put that on for less than shaving a tire, which voids the warranty.
Originally bought at Costco and the road hazard part of the warranty says 60 months. It's been about 68 months since purchase... I should check though and see what they say.
I was just guessing about the half life. Here in Charleston where everything is pretty flat and straight, tires tend to last as long as they're supposed to. Still I do have more miles on these than I thought I do (nearly 40k) so I guess the first step will to be get a tire gauge and check them.
I'll look for a used tire shop this weekend if I get the time. I called Tire Rack and it's $172 for a shaved tire shipped to my door. I called a couple of tire places around here and they said they've never heard of shaving a tire.
The used tire (if I can find one) probably makes the most sense.
