$P = 2.94 \times 10^5 Pa$

Explanation:

Normal force due to four tires is counter balancing the weight of the car

So here we will have

4F_n = mg

$F_n = \frac{mg}{4}$

$F_n = \frac{1.20 \times 10^3 \times 9.81}{4}$

F_n = 2943 N

now we know that pressure in each tire is given by

$P = \frac{F}{A}$

Here we know that

$A = 1.00 \times 10^2 cm^2 = 1.00 \times 10^{-2} m^2$

$P = \frac{2943}{1.00 \times 10^{-2}}$

$P = 2.94 \times 10^5 Pa$
