This is a basic, yet highly efficient and totally functional app which performs flawlessly. Thank-you. 😊👍

Good features and lots of useful dimensions given, but the tires seem to be rendered wider than they should be. Or maybe they look too wide because they don't have a shoulder. As it stands if the user is trying to get a square sidewall the app may suggest an excessively wide wheel or narrow tire.

Used to be able to change both tire sizes to compare my stock rims and tired to others. Now the 1st tire is stuck on 195/65/15 and I can only change the 2nd tire. So no I offsets show up. Please fix so I can make a better decision on shoes for my ride

Perfect app when you need wheel parameters too. With latest release cannot see rim ET while trying to choose value.
