It doesn't let me input tire size in the tire size tap it just said error and does not let me change it I have 3.23 with 245 40 r18 someone told me to imputed manually but I don't know the formula to do the math manually

I just told you how to do it. It's a 98. You can't just enter a tire size. Guess you shouldn't have slept through math class. Do you seriously not know what the / symbol means?

I'm pretty sure if you go to the conversion tools it has a spot to input your tire size and it calculates it for you.
