This is a great tool to visualize the potential tire choice. However, if I may point out one problem: the unit for tread height. It should be percentage (%) rather than millimeter (mm) since it is the percentage of the tread width. I would assume the calculation is done correctly and this may be just a labeling error.

If I may offer some suggestions:

1. In the Tire Diameter (mm) field, calculate the difference between the new value vs OEM in percentage with 2 significance (x.xx%). This number means how much variance of your speedo with the new tire setting. This variance can come in handy to mentally adjust your speedo you read from the car based on the new tire setting.
2. If you can high-light the distance you are calculating (e.g. fender gap, or offset from flush, etc) on the main display it will clearly show which is which. To simplify the display, you can simply use numbers in your text like 1 for Sidewall height and 2 for tire diameter and so on and display the numbers, if possible with two bars to show the ends. This will clearly present the distances to be measured and easier to convey the message.
3. Forgive my ignorance, have you calculated whether a choice of tire would rub the side wall (does not fit)? You might want to calculate the theoretical side wall gap based on the tire choice. This can come in handy.

Anyway, this is a great tool and thank you for that.

Keep up the good work!
