Great for quick conversion and love that it can be switched from miles to km. Need to get rid of the adds I'd rather pay a few dollars just to get rid of the pop up adds

Absolutely the best tire size app I've used. Would give it 10 stars if I could.

The best little app there is. I use it everyday for work. I only wish I could change the 'within allowance' tolerance.... Great app hasn't let me down yet.

Really useful app if you are planning for tyre up size

Works very well and is easy to use, but doesn't cover many of the sizes that I'm looking at. Should be fine for most people, but not for me. Uninstalled.
