Ford 1996 Bronco Manual page 305

When replacing full size tires, never mix
radial, bias-belted, or bias-type tires. Use
only the tire sizes that are listed on the
tire pressure decal. Make sure that all tires
are the same size, speed rating, and
load-carrying capacity. Use only the tire
combinations recommended on the decal.
If you do not follow these precautions,
your vehicle may not drive properly and
safely.
Make sure that all replacement tires are of
the same size, type, load-carrying capacity,
and tread design (e.g. "All Terrain", etc.),
as originally offered by Ford.
Do not replace your tires with "high
performance" tires or larger size tires.
Failure to follow these precautions may
adversely affect the handling of the
vehicle and make it easier to lose control
and roll over.
Tires that are larger or smaller than your
vehicle's original tires may also affect the
accuracy of your speedometer.
