it seems my ABS light has been on since i took my 235's off and put 31's on. althought i'm not 100% on that. i was taking to a guy yesterday and he said it's on because of the bigger tires... anyone know if this is true?

***97' blazer 4.3L,manual 5 speed(used to be automatic), electric 4x4, 2" body lift, torsion tweek, lift shakles, 31' tires*** ..and switched to composite headlights, waiting to crash because they're extremely dim!

 

Yes, it's true. You need to re-program you ECM to recognize the bigger tires.

Or just ignore the light.

 

alright, thanks for the info! i'm starting to dislike my ecm. now i knoe why people rebuild old vehicles.
