That is possible since the ABS system uses a revolutions per mile that's set
in the PCM to determine how fast the vehicle is going. The ABS pump
activation and pumping speed is determined by how fast the ABS and PCM think
the truck is traveling. So if you change tire sizes and don't re-program
the CABS or if the tire/wheel size you're using is outside the scope of what
the CABS can handle it could have an effect on how well the ABS system works
at stopping you.

I have been told by several people that changing your tire size too much may
cause the abs system to make the veichle unsafe!
Is that possibly true? We have a 96 Ram that came with 225/75X16 tires and
someone changed them to 265/75X16. Those tires are a lot taller than the
original ones. Sometimes it seems the rear brakes on that truck don't work
at
all but the linings and wheel cylinders have been replaced. We have another
ram
just like it with 345/75X16 tires on it and the brakes seem ok. is it
possible
that the extremely oversized tires cause the problem?
