5 years or 72,000 miles, whichever is soonest.
You have done 30,000 miles, which is less than 72,000. So it does not need to be done based on mileage.
2009 was 7 years ago, which is longer than 5 years. So it does need to be done based on age.
"Whichever is soonest" means whichever milestone is reached first. It does not mean you can pick which milestone to put it off for another few years. Rubber deteriorates over time. Think about when bicycle tyres go hard and crack when they're left in the shed over winter.
