I am trying to set the tire size on my quadzilla adrenaline but not sure what my tire size number they are looking for?? I have 315/75/16 on my truck but I dont know what that relates to for the adr also what is stock for my truck it was a 245/75/16

 

um anybody

 

Dont have the adrenaline, but it should need the tire size you have now. 315's are anywhere from 33" to 35" tall. Id measure the back tire for a more accurate measurement.

 

315/75/16 = 245/75/16 =

Diameter: 34.6 Diameter: 30.5
Section Width: 12.4 Section Width: 9.6
Section Height: 9.3 Section Height: 7.2

HEIGHT = ((width * aspect-ratio * 2) / 2550) + rim size
WIDTH = (width / 25.50 )

 

i just installed the adr and have the same question does any one have the answer?

 

I think, the number it wants is the tire diameter x pie so if you have a 33 inch tall tire you would take 33 x 3.14 = 103.6 and that would be the number to plug in to the adr

 

Hes a calculator for finding diameter http://www.4lo.com/calc/gearmetric.htm

 

here is another calculator http://www.web-cars.com/math/tiresize.html

 

Go to 'Hardware'.... then 'Tire Size Correction'.
The number you want will be around 106% or higher.... 105.0 works for 265's. Be sure and save it with bottom button on Pulse.
If you can get it to work (mine use to but won't anymore)... just play with the number until it's corrected!
