Tire shops won't have the equipment to re-calibrate your speedo. None that I've ever heard of anyways......

Dumb question but I keep second guessing myself. If you go to a bigger tire are you going faster or slolwer than your speedo says? I shouldn't have so many beers and then contemplate this stuff. Gives me a headache.

If you go to a bigger tire your speedo will read slower than what you are actually driving. Here is a link to see how far off your speedo is.
