## About

GarageCalc provides free browser-based automotive calculators and reference guides. Drivers can compare nominal tire dimensions and wheel offsets, estimate trip fuel costs, and work through caravan weight figures. The tire comparison also accepts manufacturer-published revolutions per mile for both tires, keeping rolling data separate from nominal geometry. Australian caravan tools use kilograms and local weight terminology. The site includes maintenance checklists and vehicle reference data, with formulas and source notes shown. Calculators do not require an account. Results are references and estimates, not vehicle-specific fitment approval or a replacement for weighing a loaded combination.
