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!

I don't know what formula you're using for your rolling circumference, but when comparing to 3 other tire size calculators online, yours is the only one with a different number.

As for the revs/mile, all calculators give different number (although some are close) for some reason.

 

Hi 3hree5ive0ero, thanks for your feedback!

You are right, here in Europe we calculate the rolling circumference considering the weight of the car and with a given speed of 40 mp/h, therefore the rolling circumference is differing. I have now changed the calculation, so the value is the same like the other calculators.

 

Hi to everyone!

I got a lot of feedback and many of you wanted to be able to input inch-values and not only metric ones. This is now possible Hope it will help you with your calculations.

If you like the tire size calculator it would be great if you could recommend it also to others!
