About the application:

LIMITED TIME MINIMUM PRICE PROMOTION! Compare tire and wheel specs conveniently and receive suggestions for tire and wheel upgrades. Help both Imperial and Metric units. What makes this apk standing out from the crowd: calculate approximate equivalent sprung (chassis) weight difference after changing to a fresh set of tire+wheel. http://www.tirerack.com/wheels/tech/techpage.jsp?techid=108 Experienced vehicle mod drivers know that a light weight tire+wheel pack with awesome quality is always a good mod investment to have. This apk helps to quantify the performance improvement that can be achieved by such investment: the equivalent sprung weight deduction with a set of 4 lightweight fresh tires and rims. This apk helps you to select make batter tire and wheel safely and wisely, because Security and Performance both matter! Tire Size Calculator is an apk that gives you concise details and intuitive interactive methods to assist you: 1. Receive suggested upgrade/replacement tire sizes, with adjustable difference variables (rim size diff./section width diff./circumference diff.) between fresh tire and old tire. 2. Calculate tire sizes, and compare tires with detailed specs, in either Imperial or Metric troops. See the visual differences between tires using the scaled tire graph with two display modes: side-by-side as two complete tire circles, or use half of each tire to constitute one tire circle. 3. Calculate approximate equivalent vehicle chassis (sprung) weight differences after change to the replacement/upgrade tire+wheel, using the following data: vehicle weight, engine max torque, vehicle 0-60 mph/0-96.6 km/h time, tire/wheel sizes/weights, in either Imperial or Metric units. Detailed description: 1. Receive suggested upgrade/replacement tire sizes, with the following adjustable difference variables between fresh tire and old tire: • Rim diameter difference (-3" ~ +3") • Section width difference (-30 mm ~ +30mm) • Tolerable tire circumference difference (-3% ~ +3%) You can conveniently select one of the suggested tires to compare to the old tire by choosing the tire from the list. 2. Calculate tire sizes, and compare tires with the following specs, in either Imperial or Metric troops: • Section Width (145 mm ~ 395 mm) • Aspect Ratio (20 ~ 85) • Rim Diameter (10" ~ 30") • Load Index (60 ~125) • Speed Rating (L ~ Y) • Suitable Rim Widths • Section Height • Tire Overall Diameter • Tire Circumference • Actual Speed when speedometer reads 60 • Actual Speed when speedometer reads 100 • Scaled visual graphs of the old tire and fresh tire You can use the scaled tire graph to see the visual differences in tire section height (sidewall height), tire diameter, rim diameter, and circumferences, in the two modes: • Side by Side: two tires displayed as two whole circles next to each another, good for seeing overall visual appearance differences. • Half Circles: old tire as the left half, fresh tire as the right half, combined to form one circle, good for seeing differences in tire section height, tire diameter, and rim diameter. Tap the tire graph to toggle between the two modes. 3. Calculate approximate equivalent vehicle chassis (sprung) weight differences after change to the replacement/upgrade tire+wheel, in either Imperial or Metric troops, using the following data: • Vehicle Weight (with old tire+wheel) • Engine Max Torque • Vehicle 0-60 mph/0-96.6 km/h time (with old tire+wheel) • Old Tire/Wheel Sizes • Fresh Tire/Wheel Sizes • Old Tire/Wheel Weights • Fresh Tire/Wheel weights Colors of the specs table cells indicate the compatibility of the fresh tire in that spec: • No color: compatible • Green: improved • Yellow: tolerable • Red: not compatible
