Arrow Tire-Size-Calculator.info | Compare tires and wheels + graphical demonstration

Hello Forum!

I want to introduce you to my newly released tire size calculator:

www.tire-size-calculator.info

You can compare your existing and future tires and / or wheels of your vehicle. You also get a nice graphical demonstration of how the tires and / or wheels look like in comparison.

You can calculate values such as circumference, speedometer difference, changes relevant to the ride height or the effect of wheel spacers and learn which tires or wheels fit best for your car.

I hope the tire size calculator can help you with your calculations and helps you in deciding on which tires and / or wheels to choose!

Would be nice if you have any suggestions or requests how to make the tire size calculator even more better.

Greetings Mike!



PS: Admins or mods are welcome to make this thread sticky to help also new members of the forum who could need this tire size calculator._a_

This is very cool. Can save $$$ by going with a slightly taller tire 205/50 vs current 225/45. hardly a difference. Thanks for the info!

Nice tool. Just a question though, why doesn't the "Outset difference per side" change when you change the new tyre width?

I.e these 265 wide tyres are showing the same "Outset difference per side" value as those 235 wide ones (with all other figures being the same).

Does it only work out the difference between the 2 "rim faces", as opposed to entire package including the tyre? If so, it would be a nice addition to have a figure that does take the tyre width into consideration, so you can see the real difference with respect to your guards

Cheers.

I'd have to sit down with Excel (not happening tonight) to verify, but it appears on the surface your assumption is correct (inset/outset) is for the wheel.

The problem with getting accurate tire info is that all tires are different and any calculation would be purely theoretical. YMMV

Have a look at this tool (http://www.rimsntires.com/specspro.jsp) it does seem to take into consideration tyre width, so may help you as a guide.
