互換タイヤX app for iPhone and iPad

"CompatiTireX" is an application that calculates the outer diameter for changing the size of a regular car tire and easily checks the compatibility of the tire.

Inch-up, inch down, when changing the width of the tire, the problem is the calculation of the outer diameter of the tire. Moreover, the display of tire size is different in unit, width is cm, oblateness is%, wheel size is inches. For example, the display 205 / 55R16 means that the section width of the tire is 205 cm, the flatness ratio (cross section height ÷ section width) is 55%, and the wheel size is 16 inches.

[Using Info.]
1. Set standard tire size (width(mm), oblateness(%), wheel size(inches)).
The value increases with the "+" button,
It becomes small with the "-" button

2. Set the number of inches of compatible tire to the desired size

3. Press "Go!" button for Auto search (optional).
Recommended tire size will be displayed.

4. Optionally change the compatible size inch (wheel size), width, oblateness, arbitrarily change the difference and consider the size of your choice.

[Caution]
Since this is simply calculated as a theoretical value, interference with the brake (inner diameter of the wheel) and interference with the fender / suspension are not taken into consideration, and compatibility between the tire and the wheel (rim width, offset There are also), so please consult with the shop well when purchasing.
Please note that we do not guarantee anything about the calculation result of this application.
