Tire size calibration
 
Has anyone updated their tire size after they got aftermarket wheels/tires? My size is def within the acceptable standards, but my Trinity gives me with the option to update the size, but every time I try to apply it say "failure to update tire size". I have tried updating through the quick adjust function, when installing a CMR and canned-91 tune modifying the parameters before installing, and quick adjust with the tune already installed. Anyone run into the same issue? What am I doing wrong?

maybe its becasue you have a cmr tune? What sizes are your tires?

its a 2wd so I was told to use the rear sizing = 295/40r20

I tried installing it with and without the CMR tune...and also with the canned 91 tune on there too

I have the most recent (released 7/1/10 u7137_1r07b). Is there a different one?

Do u use the quick adjust with the trinity to apply tire size change? Or before tune install?

What year is your Jeep? I was able to adjust mine with the preditor.

Brad, thats the most current one, very weird it doesnt work. I just run a quick adjust, and type in the tire size, and hit apply.. It Writes, and everything works. Stupid questions... Do you have the car running? it needs to be in the ON position but not running. Also, are you doing it before or after a tune? usually I adjusted mine after i installed a tune.
