Tire Sizes - % Differences in Tire & Wheel Sizes 2.0

The Tire Sizes app offers a comprehensive resource for all aspects of tire sizing and related information. It provides detailed tables for calculating differences in tire sizes, particularly useful when considering upgrades such as larger rims or low-profile tires that aim to preserve the original tire circumference. The app also contains extensive reference material, including visualizations of tire sidewall data and a glossary to facilitate understanding key terminology.

This tool is especially valuable for users seeking to:

• Determine the percentage change between current and new tire and wheel configurations, ensuring compatibility and performance stability.
• Ensure that modifications to tire or wheel size do not necessitate speedometer recalibration.
• Make informed purchasing decisions by understanding tire specifications and capabilities.
• Gain clarity on proper tire use and maintenance, such as maximum inflation pressures.
• Convert measurement units and tire pressure values efficiently.

In terms of functionality, the app allows for precise adjustments:

• Users can select different increment settings for measurements (e.g., 1 psi, 2 psi, 5 psi, 10 psi) via toggle buttons located on the bottom bar. The default view displays the largest available increment for convenience.
• The search feature within data tables is accessible by scrolling upward to reveal the search box, facilitating quick location of specific data points.
• To accommodate extensive unit conversions—especially when viewing conversion tables with numerous units—rotation to landscape mode is recommended, providing a wider display area.

The app categorizes information into several broad sections:

• Selected New Tire Size – detailed tables illustrating diameter, circumference, and percentage differences.
• Glossary – comprehensive definitions and visual diagrams of tire sidewall features.
• Detailed Tire Size Data – information derived from tire codes.
• Load Index
• Speed Rating
• Load Range
• Tire Pressure Unit Conversion
• Measurement Unit Conversion

The supported measurement units include millimeters, inches, pounds, kilograms, miles per hour, kilometers per hour, psi, kPa, bar, and kg/cm².

This application is designed as a universal app; a single purchase grants installation across all compatible devices, including iPhone, iPod Touch, and iPad.
