Do any Tuners Adjust your Speedo for Tires?

[Clayton74]

I know it's a dumb question but I'm new to Fords and searched but didn't find anything probably because all you guys already know the answer . Most of my experience is with GM's and there speedos are adjusted via the tuner, but I checked on the Edge and Diablosport but neither seem to adjust the speedo for tires size.

Thanks!

Edge evolution CTS does

from the users manual"The CS/CTS Evolutions will allow you to re-calibrate the speedometer
for non-stock tire size. To do so select Tire Size in the Options
Menu.

My Superchips 1805 does too, got it used for $125, check the classifieds every now and then, someone may be selling one

You can't adjust the tire size with a tuner. You need to take it to the dealer or through auto-enginuity (don't know for sure on the latter). I took mine to the dealer and they charged me 1hr, so about $100. They can only go up to 35" tires if I remember correctly. If you go bigger, you need something like the superlift tru speed.

so how far off will the speedo be? curious cuz my truck sits on 35s and i have wondered since i got it how much over the linmit ive been speeding?

You are off by about 10% if your truck came stock with a 265/75/16.

Also thanks for the replies to this thread. Good to know the tuners should be able to adjust my speedo.

so 10% faster than what speedo says right? thanks for the info!
