  • 15x8s will throw off my speedo?

    Have a chance to get some Prostars w/ 28x10 MT ET streets, but the wheels are 15x8s. So that will throw off my speedo right? :(

    Probably so, depending on your tire/wheel combination. Here's an excellent calculator:

      28inch tire is taller then stock 25-26inch tire. You'll be going faster then what the speedo says.
