Tire Calculator

Please refund the purchase price for this. Does not support current iOS versions so app has been deleted. Do not buy this app.

This app used to work. Hasn't worked for a couple years now, very disappointing. App not compatible with newer IOS software. This app should be removed.

The app worked fine and after upgrade just crashes every time you try to use it

Tried to use. App closes after pressing calculate. Not working junk

Works great. I use it most every day. A new tire graphic that shows comparison in size would be nice in the next update.

Very good app for people who are looking at alot of tire sizes. Would like to see this app add a wheel offset calculation to be able to compare wheel / tire combos. Ifound myself using this app for tire sizing and going online to use the wheel offset calculator on 1010tires

The link given for Extreme Software is an invalid link and the Support link does NOT have any way to ask for support/give feedback. I've had this software for quite awhile yet today I was denied an update because I only have iPhone OS 3.1 installed. I wanted to ask what was in this app that REQUIRES iPhone OS 3.1.2. Previously, I've had no problems with this app, but because of the inability to get support, I cannot in good conscience recommend it anymore.

Great now someone just needs to make a tire fitment guide I'd buy that...

All it needs is a chart of standard tire sizes and the ability to save your inputs for later.

Needs a recommended wheel size, as well as display tire width. Also a cool graphic would be to show new tire next to old so you can get a visual of size change.
