[backwoodscountryman]

OK so i am math inept.Its not my thing.Never has been.Also cant stand it,lol. So need help with the Edge's formula for correct tire size to input into my Edge.Thanks all

Here is my size 315/70R17

Instructions from the Edge Evo manual
1. Multiply,width,ratio and 0.02
2. Multiply rim and 24.4
3. Add steps 1 with 2
4. Multiply step 3 with 3.1416
5 The result will be the circumference of your tire in mm

Thanks all

I got 2688.58 mm

315 x 70 x.02 = 441

17 x 24.4 = 414.8

441 + 414.8 = 855.8

855.8 x 3.1416 = 2688.58

I get 2888.39 greg. backwoods tire size is listed in millimeters. Yours is listed in inches. I converted your size to millimeters then did the math he posted.

 

[yz85rider2002]

yeah im going to have to figure something out

i got 2888.39 for mine. How do you go about entering that into the edge? do you have to enter just the first four digits or what?

when you go to change the program level, select custom tire size. Use the up and down arrow to increase/decrease the value in mm
