Riley 4 average tire pressure is 30.261 psi. If it is tough for you can round it 30 psi for all 4 tires.
Check the Riley 4 tire pressure when the tires are cold - first thing in the morning is best. If you've been driving for a while, you'll want to wait several hours before checking your tire pressure. Remove the caps to your tires' air valve (keep them in a safe place, like your pocket). Place the tire pressure gauge on the air valve firmly to receive a reading. Take the tire pressure reading 1 - 3 times to get a good average and reduce the risk of anomalies.
