You must use different speedo gears, Ford makes speedo gears with different number of teeth, the amount of teeth on the gear determines what the speedo displays.Usually for every 1 inch of over size from stock tires will throw the speedo off by about 5 MPH. Usually a change of 1 tooth size is equal to 5 MPH. Hope that helps.

YES BUT THE RIDE WILL BE ROUGH IT'S NOT EVEN WORTH IT. IT LOOKS NICE BUT AT THE SAME TIME YOUR KILLING YOUR TRANNY YOUR SPEEDOMETER WILL BE WAY OFF SO YOU WILL PROBABLY BE GETTING TICKETS UNLESS YOU RECALIBRATE YOUR SPEED FOR THE TIRE SIZE CHANGE.
