What the next sizes up change

From each stock size, the common larger sizes on the same wheel: how much taller, how far the axles rise, what the speedometer shows and how the axle ratio behaves. Whether one fits your Bronco depends on lift, wheel offset and trim; these figures don’t say.

Assumption, not data

Heights come from the size code. A real tire of a size measures within about 1.5% of it, depending on brand, tread, wheel width and pressure, so each figure carries that range. The axles rise by half the change in height; the body only rises with a lift.
