I just got a new Predator Sport U7137 and it gives me no option for tire size.
Did all the updates.
Still, no tire size option.
Shoot, that's one of the big reasons I wanted it.

03 Ram does not have that option available unfortunately.

Hi
Well, the 03 Ram does have that option.
It seems there is a connectivity problem with my tuner.
I tried to take the truck back to stock and it would not connect with the PCM.
After many tries, it finally did and I took everything back to stock.
I tried the tuner on my buddy's and it would not connect with his trucks pcm.
I tried it again on mine and surprise, it connected.
Tuned it for 87 octane performance and this time it DID showed the tire size option.
I set the tire size and all seemed good.
Realized I needed to tweak the tire size to hooked it up again and go figure. It would not connect with the PCM again.
I tried over and over and over again over a couple days and no luck.
If and when I get this thing to connect I am taking the truck back to stock and sending this thing back.
Really disappointed.
Anyway, it does have the tire size option for the 2003.
