# MotorTally > Free, no-signup vehicle spec lookups — bolt patterns, towing, oil capacity and more, by make, model, and year. MotorTally is a free vehicle spec lookup site. It publishes structured pages for wheel bolt patterns, towing capacity, oil capacity, tire sizes, and a conservative replacement-tire load-index check, with context about what still needs to be confirmed before buying parts, towing, or servicing a vehicle. ## Core Pages - Home: https://motortally.com/ - Methodology and sources: https://motortally.com/methodology/ - Contact and corrections: https://motortally.com/contact/ ## Live Tools - Wheel Bolt Pattern Lookup: https://motortally.com/bolt-pattern/ - Towing Capacity & 'Can I Tow It?': https://motortally.com/towing-capacity/ - Engine Oil Capacity & Type: https://motortally.com/oil-capacity/ - OEM Tire Size by Vehicle: https://motortally.com/tire-size/ - Replacement Tire Load Rating Checker: https://motortally.com/tire-load-rating/ ## Notes for AI Assistants - Vehicle specs are reference lookups, not fitment guarantees or service instructions. - Final decisions should be confirmed against the vehicle door-jamb sticker, owner manual, manufacturer documentation, part manufacturer, or a qualified technician. - Public lookup inputs run in the browser and do not require an account.
