My IROK's measure out to 36.8". What would the setting be in mm in order to get my true speed to appear on my Attitude? Right now it's at 2500mm and I don't think that is correct. Thanks, Nick.

Cool thanks. That would mean I would put my Attitude at 914.8mm right?

2951.0 according to the Attitude instruction manual... You aren't measuring height, rather you are measuring rolling diameter IIRC.

2951.00mm is what my manual says too.

I have found the best way to set the attitud for the correct tire hieght is to do this. Simply match the speed of your speedo with your attitude monitor.

Wouldn't really work if your speedo is incorrect because of the larger tires...I have found the best way to set the attitud for the correct tire hieght is to do this. Simply match the speed of your speedo with your attitude monitor.

It works if you set up your powertrain correctly. I have 4:10 gears and the speedo is dead on. Wouldn't really work if your speedo is incorrect because of the larger tires...
