What should the tire diameter be for 37" tires? I cannot find the owners manual for my edge anywhere and just put 37's on my truck. Any help would be appreciated.

Thanks,

Owner manual available for download from their site.

You can measure directly - the BEST, most Accurate approach - three rotations/ divide by three.

Or you could cheat and use this: http://www.net-comber.com/tirecalc.html

 

most tire manufacture list this on their web sites go their first the next best thing is to put a mark on your tire and ground then roll it four or five times around then measure that and divide it buy the times you rolled it

 

A good rule of thumb for calculating tire sizes from inches...

((inches x pi) x mm per inch) x squish factor = final mm

((37 x 3.14159265) x 25.4) x .95 = 2805 mm

Again, the most accurate way is to roll it, measure the distance and divide the number of times rolled.

Enjoy.
