    This is one of the better apps. The graphics to show tire size and fitment is spot on. Only thing I would add is a wheel spacer input for serious folks like me to tune a setup just right. I would recommend everyone use this tire size cal. Before any other for the simple fact that you can see exactly what you are trying to fit.

    What this needs to be complete, is a side profile view like Aimen RG's Tire Size Calculator app. Also could use configurable colors for both the tires and wheels, so I can tell which tire goes to which wheel when comparing close sizes. Although the update seems to add additional sizes you can compare with, you can only compare to the original and not with your other sizes.

    Good app but it would be nice if you could give the tire width difference and proximity to the strut, as you do with the wheel info Perhaps with the lift/level calculation? Food for thought. Great info provided with the current version. Thanks

    Not a bad app but the owners need to fix the speed difference values because they are backwards

    Great App for car enthusiast. My wish was to play with different tires and wheels profiles to see differences when compared to OE . I'm also able too see how the profiles would possibly fit my car.

    It's a good comparison app for tires my only complaint is the picture at the end where it shows you is cut off at the top and bottom so you can't see the actual height of the tire comparison.

    The simple visual representation gives a general idea of relative rim and tyre size changes. Rather than saying a rim will be -25mm further away from the strut, you should change it to say the rim will be 25mm closer to the strut.

    Redesign only displays in Russian. *edit I was able to find the settings for the language after poking around for a while.

    Cool and simple. Hod do I tell the calculator to compare with second and third Desired setup? Would be cool if I could have 2 original setups. My car has different wheels in front and back.

    I'm always looking for the perfect fit, and with this app it's so much easier to know if it will fit before buying the wheels! I LOVE it!

    Greatest app for tire size comparison. No other app even comes close. Fast and simple to use..... If it only was color coded images ?

    I love this app! Can't imagine a better process to size aftermarket tires and wheels.

    Tire diameter appears to be just the opposite as well as the difference in road speed.
