CheckFitment answers with numbers, not guesses. Ask for a vehicle's bolt pattern, center bore, thread size, lug torque and factory wheel, offset and tire sizes: every figure comes from the site's dataset, where each specification is cited to manufacturer documents and marked verified or openly unverified. If your vehicle is not in the dataset, the app says so instead of inventing a spec. Compare your current wheels and tires with a new set to see how far the outer edge moves toward the fender and the inner edge toward the suspension, the diameter and ride-height change, the speedometer effect, and, with your measured clearances, a fits / tight / rub verdict. Check what a tire size change does to diameter, speedometer and odometer; which spacer reaches a target offset and whether a slip-on still leaves enough stud thread; what your axle ratio behaves like on bigger tires and which gear set restores stock feel; and what 5x114.3 is in inches, which look-alike patterns do not interchange, and which vehicles use it. Reference only: confirm every figure against your vehicle's documentation and door-jamb placard, torque to the manufacturer's figure, and have fitment checked by a qualified shop before driving. Free, no account, no prices, no shopping links; the app asks for no names, VINs or plates and stores nothing.","plugin_category_id":"productivity","privacy_policy_url":"https://checkfitment.com/privacy/","screenshot_urls":[],"short_description":"Bolt pattern and wheel fitment","terms_of_service_url":"https://checkfitment.com/terms/","website_url":"https://checkfitment.com"},"keywords":["bolt pattern","wheel fitment","wheel offset","lug nut torque","wheel spacers","tire size calculator","gear ratio"],"onboarding_skill_name":null,"requires_local_executor":false,"skills":[],"version":"1.0.0"},"scope":"GLOBAL","status":"ENABLED"},"research":null,"package_metadata":{"name":"checkfitment","author":{"url":"https://checkfitment.com","name":"Rainer Lang"},"sources":[{"path":"plugin.json","sha256":"12768c2a81825a7dc0f48125055d1c3b3cb1191c2dc130032bde0a5db81a7650"}],"version":"1.0.0","commerce":false,"homepage":"https://checkfitment.com","keywords":["bolt pattern","wheel fitment","wheel offset","lug nut torque","wheel spacers","tire size calculator","gear ratio"],"artifact_id":140101,"observed_at":"2026-11-03T19:19:47Z","support_url":"https://checkfitment.com/about/","capabilities":["Look up a vehicle's bolt pattern, center bore, thread, lug torque and OEM wheel, offset and tire sizes with sources","Compare current and new wheels and tires: poke, inner clearance, diameter, speedometer, fits / tight / rub","Tire size, speedometer and odometer change; spacer size with the stud-engagement check; gear ratio and regear","Convert bolt patterns mm and inches, warn about look-alikes that do not interchange, link the page on checkfitment.com"],"field_sources":{"name":0,"author":0,"version":0,"commerce":0,"homepage":0,"keywords":0,"support_url":0,"capabilities":0,"release_notes":0,"review_case_counts":0,"commerce_description":0,"availability_countries":0},"release_notes":"1.0.0 - First version.
