    Default changing tire size on diablo sport

    i am sure some one else has run into this problem. when i change my tire size on my diablo it makes my brake and abs lights come on... when i change the tire size back the lights do not come on at all. when i put the tire size to a 33 the lights only come on after about 5 miles on the highway... if anyone has run into this and figured it out let me know. i don't care if my tire size is right on i just want it close with no lights coming on

    I know with my truck I have 315/70-17 with 4.10 gears and my Diablo gives me no issues. Are you sure your entering the right tires size? I know that sounds insulting but I've had guys do that. Have you changed your gears? Try tricking the computer by putting the trucks stock size tires in.

    ya when i put in the stock tire size the lights dont come on when i put in the 325's they come on right away when i put in something in the middle the light comes on only after i drive on the highway... if i have to ill just leave in on the stock tire size to keep the lights off but i know my speedometer is not right off by about 7mph

    Have you tried e-mailing Diablo? They also have a forum that may help you.

    i had the same problem i put lt285 70 r17 tires on but the abs and brake warnig light came on so diablo sport had me set it at 285-65r17 and change my speed limiter 1 setting to 120mph fixed the problem! hope this helps oh and BTW the diablo web site is a great help so sign up they have tech's who monitor it and answer questions usually within a day or so!! i love my predator it really woke up my 08!!!
