Help me on a physic problem

Ok here it goes

A tire is filled with air at 6.2 C to a pressure of 2.17E2 kPa. If the tire reaches a temperature of 38 C, what fraction of the original air must be removed if the original pressure is to be maintained?


This should be a pretty easy problem right? For some reason I can't get the right answer using PV/T = nR


edit: Ok, I figured it out since none of you guys wanted to help 🙁
The pressure given is the gauge pressure, which includes the atm pressure (101Kpa). I didn't take that into account.
