I'm looking for the reasoning behind the recommendation that tire OD should not be increased beyond 15% above stock on ABS equipped trucks. Right now I'm only interested in the effect of tire OD on the ABS system. I'm not interested in the stability problems of "Monster Trucks".
If I understand the technology, the idea is to modulate the hydraulic pressure to the brake caliper of any wheel that is exhibiting signs of slip (slowing down relative to the other wheels). I understand that using larger OD tires will require a commensurate increase in hydraulic pressure at the caliper in order to obtain the same braking effect. However, the effect that tire size would have on the modulation is unclear to me.
If I visualize a "DC" pressure with an "AC" component superimposed as the hydraulic pressure on the caliper during ABS operation is the "AC" modulation amplitude proportional to the "DC" level? Is this how varying vehicle loads are accomodated?

Gunnar
