I just bought some 295/70/17 Nitto tires and according to a tire calculator, going from a 235 tire to a 295 tire, my speddo reads 65 mph however im really going 72.5mph.

Can I get my speedometer recalibrated at a shop or at the dealership? If so, which is my most economic choice for the mean while.

Thank you all for your help!

 

Both can probably do it, but you might as well get a Xcal 2, you won't be disappointed

 

I believe your dealership can only recalibrate your speedo for OEM tire sizes. If you have them recalibrate you truck for the 275/65-18 tires from the FX-4, that will get you close.

 

Thank you to both of you! Hopefully tomorrow I will try to get this done.
