Hey guys, first off ive had othe programmers before and i LOVE the diablosport. I just had new tires put on and i was curious if i can adjust for these tires. I had 285/75/16 and went to 33x12.50 17s

[mikel]

yes....its inthe modify tune menu.

Ive searched in the modify tire size and it only shows metric, i cant adjust for actual tire size. I just realized that haviong it tuned for 285/75 r16 is affecting my shift points when my tires are bigger

[mikel]

sounds like an older tool....whats the revision?

i do believe its a 2.13, if that sounds right

Well, not counting variations from one brand to another, ( there can be a big difference in the same size tire between say a BFG and a Goodyear ) a 285/75-R16 is the equivalent of a 33x11.50-16. Your new ones should be a wider tire with a larger wheel/shorter sidewall, but by specs would be the same height. Granted, due to manufacturer variations you may be taller now, or shorter, for that matter, but you should be pretty close to the same. You may not need to adjust anything.

I went 33x12.50 r17 now with cooper STT now, from stock rims and liberator all terrains. So i went a size up and i KNOW these tires are taller

Well, yeah, like I said, different brand/style can make for different height. I was just saying by standards they "should" be pretty close.

By the way, you will love those tires! I just put 37x12.50/R17 STTs on my H2, and they are awesome. I have run them on rock, mud, and sand so far, and they have impressed me a lot. And they ride very smooth and balanced great. Only thing left to see is how long they last and how they do on snow.

Is there any update for my predator? I have the 2.13 version, how do i get the newest provisions so i can get the most out of my tunes?
