Ever more important with todays highly integrated computing system...it needs to know what tire is there
Don't know if they need dia and/or revs per mile to calculate whatever decision it needs to make
Traction control, sway control, trailer control, steering control, tranny gear selection, AND control who knows what else...
Even 4x4 control...if you have it...
LOL poor ole Uncle Ben... hope someone Quotes and paste as Bennie has me on his ignore list...:R
"needs to know what tire is there" Traction control, sway control... all work from monitoring wheel speed, using the ABS wheel speed sensors, if you have changed OEM tire diameter the computer needs to have that info imputed.
