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 Gladiator 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.

Fitment guides for the Gladiator

Jeep · Gladiator

35-inch tires

35s are a straightforward target on many Gladiators, especially Rubicon and Mojave. Sport and Overland have less factory clearance and benefit more from added ride height and carefully selected backspacing.

Trim-dependent fit

Jeep · Gladiator

37-inch tires

37s are realistic on a Gladiator, but the answer changes by trim. Rubicon and Mojave provide the best starting geometry; non-Rubicon builds usually need more suspension, wheel and fender planning.

Viable on the right trim
