Wheel & Tire Fitment Playbook™
Measure first. Preserve load and safety. Clear the brakes and suspension. Protect TPMS, ABS, stability control, ADAS, and AWD assumptions. Make the setup work in motion—not just in photos.

Replace screenshot-and-hope fitment with a measured vehicle system.
A wheel can bolt to the hub and still be wrong for load, brake clearance, steering geometry, tire construction, TPMS, ABS, ADAS, AWD circumference, dynamic compression, or the real weather and use case.
Start from the exact factory configuration.
Record OE tire sizes, placard pressures, wheel dimensions, bolt pattern, hub bore, fastener seat, offsets, axle-load information, brake package, suspension, and option differences before modeling a change.
Model the wheel and tire as a moving package.
Evaluate caliper and barrel clearance, strut and spring space, outer fender position, steering lock, articulation, dynamic compression, loaded conditions, wheel width, offset, and tire section shape.
Preserve load, pressure, electronics, and driveline assumptions.
Verify load index, speed rating, construction, pressure strategy, TPMS compatibility, rolling diameter, ABS and stability behavior, ADAS implications, and AWD circumference or tread-matching requirements.
A complete fitment workflow from factory reference to shakedown.
Dimensions, load, pressure, and construction
Work through factory references, diameter and width, offset and backspacing, bolt and hub geometry, tire size, load index, speed rating, construction, pressure, age, and storage.
Physical clearance, electronics, and handling
Evaluate brake, suspension, fender, steering, and dynamic clearance plus TPMS, speedometer error, ABS/stability, ADAS, AWD circumference, scrub radius, rotating mass, stagger, compound, and alignment.
Buying, test fit, installation, and troubleshooting
Use dimension sheets, brake templates, physical test fit, return-policy gates, mounting and balancing controls, torque and retorque, hardware checks, post-install shakedown, and structured diagnosis for rubbing, vibration, pull, TPMS faults, and wear.
“Bolts on” is not the same as “fits safely.”
Confirm manufacturer-approved rim width, wheel and tire load ratings, vehicle requirements, brake clearance, fastener geometry, pressure guidance, and dynamic behavior before treating appearance or a marketplace fitment badge as proof.
Measure. Model. Test-Fit. Shakedown.
Build the factory baseline first, calculate each candidate against it, preserve the pre-mount return gate, verify the physical car before commitment, then use a disciplined installation and road shakedown to catch what static measurements cannot.
