Hello,


my tire size is 33x11.6/26 = 295/30/26 what would i put for the tire size? under custom settings?


thank you

 

the Edge manual says 2632 but they do not allow for squish. I would start with 2553, which allows for 3% squish.

 

thank you.

 

After changing it, compare the speed readout on the Edge to a GPS and adjust till they are the same.

 

Or if you want to do something much easier, check your trip meter to a GPS on a trip of more than 10 miles. If the two odometers match up then your tire size is good.

 

did his advise work for you? i've had my edge programmer for a couple years now and i've NEVER been able to get mine adjusted correctly yet. not even the professional installer was able to. between the programmer, the factory speedometer, and my navigation...i've got about 3 mph difference while at normal highway speeds. annoying but unfortunately, i've gotten used to it. any help you could throw my way would be great too. thanx!

 

Get your programmer in sync with the navigation and you will be accurate. The truck speedometer is always 2-3 mph fast. It is a well known fact that Ford builds them that way.

 

it is? why?

 

Mechanical variations in the analog speedometer display.

Legal reasons (better to have a fast speedometer than a slow one).
