    New wheels/tires, speedo change?

    I just upgraded my wheels/tires from the stock 16s to 295/35/18s in the rear. (the stock wheels w/ tires are for sale by the way) Would I need to adjust the odometer/speedometer to account for this change in order to read an accurate speed/mileage? And can this be done with a hand held?

    If the new wheel tires are close to the same overall diameter of the old ones you won't need to change anything.

    Your speedo will be 1.8% slow, meaning if your doing 60mph you will actually be doing 58.9mph. Hope this helps. No point in recalibrating speedo.
