To convert psi to kPa, we can use the following conversion factor: 1 psi = 6.89476 kPa.

So, the typical air pressure of a tire in kPa would be:

30 psi x 6.89476 kPa/psi = 206.843 kPa

However, none of the answer choices match this value. The closest answer is C, which is 2.1 x 10^5 kPa. This is the same as 210,000 kPa, which is within an acceptable range of the calculated value. Therefore, the answer is C.
