nitrigen gas is used to inflate the tyres of Lewis Hamilton's racing car if the tyre is inflated to a pressure of 2,2 atm at 25 degrees celcius and he takes the car for a lap it heat up to 50 degrees celcius what is the pressure at this temperature

Tire pressure gauges do not read the absolute pressure, but the absolute pressure is what must be used when applying the ideal gas law.
If the gauge says 2.2 atm, the actual absolute pressure is 3.2 atm. The absolute pressure at the higher temperature is then
(323/298)*3.2 = 3.47 atm. The new gauge pressure will be 2.47 atm.
If they say the answer is (323/298)*2.2 = 2.38 atm, they are wrong.
