Tire Size Calculator vs Decision Widget

MORE SIZE SYSTEMS. THE SAME DEEP WEIGHT MODEL. Compare passenger-car, light-truck/high-flotation and motorcycle tire sizes in one focused calculator. TireCalc supports modern metric sizing, legacy full-profile sizes, LT direct-diameter designations, and catalog-backed motorcycle metric, inch, alphabetic and ATV/UTV formats. GO BEYOND SIZE: ROTATING WEIGHT Tire and wheel weight is rotating, unsprung mass—not just another number on a scale. For car and light-truck comparisons, enter each tire and wheel weight plus vehicle weight, peak torque and 0–60 time. The app models the total mass change and rotational inertia of all four assemblies, then displays an estimated equivalent vehicle-weight range during acceleration. Enthusiasts can compare lightweight setups quantitatively; first-time buyers can see why reducing a few pounds at each wheel may matter more than the scale alone suggests. The result is shown as a range across several mass-distribution assumptions, not as a misleading single claim. One-time purchase. No ads, subscriptions or data collection. COMPARE THE NUMBERS • Overall diameter and circumference • Section width and sidewall height • Actual vehicle speed at 60 and 100 • Load index and speed rating • Tire and wheel weight • Four-wheel mass change, rotational inertia and modeled equivalent vehicle-weight range MORE WAYS TO ENTER A TIRE • Modern passenger/LT metric: widths from 125 through 405 and profiles from 20 through 85 • Legacy full-profile: exact table-based dimensions, including applicable “82-series” equivalents • LT/high-flotation: direct overall diameter, width and rim designations • Motorcycle: catalog-backed metric, inch, alphabetic and ATV/UTV sizes, including structure and rim-code distinctions FIND CAR AND LT SIZE ALTERNATIVES Set allowable changes for rim diameter, section width and circumference. TireCalc generates alternatives you can select and compare instantly. SEE THE DIFFERENCE Use scaled tire diagrams in side-by-side or half-circle mode to understand how two setups differ visually. Switch between imperial and metric measurements at any time. BUILT-IN GUIDANCE The Size Guide explains each supported format and its limits. A valid designation is not vehicle fitment approval: load, speed, rim, clearance and manufacturer requirements still apply. Never translate a motorcycle rim code into inches by appearance, and never use a calculated result as permission to mount a tire. Always confirm final tire and wheel compatibility with the vehicle or motorcycle manufacturer, the tire manufacturer, and a qualified tire professional before purchasing or installing equipment.

Thanks to this application (and the other Widget apps from PacoLabs), you can now customize the Home screen and the Today view of your device, by adding custom widgets for some specific purposes. From anywhere in your device, you'll have access to your own information and actions. Each Decision widget allows to view 1 to 6 different decision wheels on the same row. Each decision wheel can help you to take a decision and can randomly choose one item among several choices. A nice short animation will add some suspense to the random choice. Here are some usage ideas : * A simple YES/NO decision. * Selection of a person in a team. * Get a random action that a friend will have to do. * Get a random color. * Handling a particular situation (you can use Emoji smileys as the different choices) * Get a random dice value. Each choice can have its own text and colors. Up to 30 different choices can be defined, and every choice can be duplicated up to 10 times in the same decision wheel. A title can be associated. Various parameters can be changed (like the font name and size, the tick sound). Those Widgets are compatible with the new iOS 14 Home Screen Widgets. The application is really easy to use and is adapted to the fresh look of your device. Dark mode of iOS13 is supported. In Today view: You can add as many widgets as you want and they will be displayed in up to 3 different lists. Those same lists will be available in the Today view and in the application (although it is possible, if you want, to hide some widgets in the Today view). To avoid overloading the Today view, when too many widgets are displayed, an intuitive control will allow you to navigate from one widget to another. Even if the main purpose of the app is to view the widgets in the Today view, it can also be very handy to view them directly in the application (a long press on a widget in the Today view will open it directly in the main application).
