Fitment is a complete configuration
Record model year, trim, factory fenders, axle ratio, wheels, tires, suspension, lift, bump stops, alignment, steering stops, current modifications, normal payload, towing use, and spare location. Compare manufacturer-measured tire diameter and width, not only the nominal sidewall label.
A tire can clear during straight street driving and still contact a control arm, sway bar, fender, bumper, wheel well, body, or suspension component at steering lock, compression, and articulation. Sway-bar-connected and disconnected travel can produce different paths.

Record the baseline before selecting tires
- Model year, Sport, Willys, Overland, Mojave, Rubicon, or other verified trim and factory package
- Factory fenders, bumpers, axles, axle ratio, suspension, shocks, bump stops, sway-bar equipment, and steering stops
- Door-jamb tire size, pressure, payload information, current tire condition, and towing guidance
- Wheel diameter, width, offset, backspacing, load rating, brake clearance, and mounting details
- Tire brand, model, construction, load range, measured diameter, section width, tread width, and approved wheel range
- Lift, springs, shocks, control arms, track bars, alignment, axle centering, and previous clearance changes
- Normal passengers, bed cargo, permanent rack, tent, armor, bumpers, winch, trailer tongue weight, and operating load
- Under-bed spare space, exhaust and hitch clearance, hoist condition, tools, and recovery access
Wheel and tire dimensions change different clearances
| Variable | What it changes | What to verify |
|---|---|---|
| Measured diameter | Ride height, gearing, braking leverage, acceleration, speed indication, spare clearance, and compression path | Actual specification, load, pressure, bump stops, fenders, wheel wells, and under-bed space |
| Measured width | Control-arm, sway-bar, fender, bumper, body, and rear-wheel-well clearance | Section and tread width on the selected wheel, steering lock, articulation, and load |
| Wheel width | Tire shape, bead support, sidewall position, pressure behavior, and approved fitment | Manufacturer range, load rating, brakes, tire profile, and use |
| Offset and backspacing | Inside clearance, outer poke, scrub radius, steering feel, bearing and joint leverage, and fender coverage | Both values, not appearance alone, through complete steering and travel |
| Tire and wheel mass | Unsprung weight, braking, acceleration, steering, damping, fuel economy, payload, and towing response | Complete assembly weight and its effect on the actual use case |
Check the entire tire path
Front steering lock
Inspect control arms, sway bar, links, frame, bumper, fenders, liners, steering stops, brake hoses, and wiring in both directions.
Front compression and articulation
Check bump-stop engagement, shock travel, fender and body clearance, steering angle, axle position, and connected or disconnected sway-bar state.
Rear compression and articulation
Check wheel well, fender, frame, shock, sway bar, brake line, track bar, control arms, bump stops, and bed-side clearance.
Under-bed spare
Confirm diameter and width clearance around the hitch, exhaust, axle, track bar, bed, hoist, and departure area at operating load.
Payload and towing
Added assembly weight consumes payload and can alter braking, steering, acceleration, heat, shifting, stability, and trailer response.
Road systems
Confirm pressure, balance, alignment, speedometer, assistance systems, steering feel, braking, noise, and fuel use.
A safer fitment process
Identify the exact Gladiator
Record trim, powertrain, axle ratio, fenders, suspension, sway-bar equipment, lift, bump stops, wheels, and changes.
Define tire performance
Balance weather, road use, terrain, construction, load rating, towing, noise, repair needs, and weight.
Confirm wheel compatibility
Check approved width, load rating, offset, backspacing, brakes, steering, control arms, and fender coverage.
Use measured tire data
Compare manufacturer diameter, width, tread, approved rim, load, and complete assembly weight.
Test dynamic clearance
Inspect steering lock, front and rear compression, connected and disconnected articulation, bump stops, and representative load.
Verify the spare
Confirm under-bed space, hoist, hitch, exhaust, tools, access, and a practical recovery plan.
Road-test and calibrate
Evaluate pressure, balance, alignment, steering, braking, acceleration, shifting, towing behavior, speedometer, and assistance systems.

Personalized planning
Build Your Gladiator Plan
RigAI uses your model year, trim, engine, transmission, axle and transfer-case equipment, factory tires, suspension package, towing equipment, payload label, current accessories, bed load, trailer tongue weight, driving profile, and planned trip load to organize what to consider first and what can wait.
