St. Peters Nitrogen Tire-Filling Station Opening to Residents in April—Appointments Required

March 13, 2019
Here’s an easy way you can improve gas mileage for your car: Make an appointment to fill your tires with nitrogen at the St. Peters Nitrogen Tire-Filling Station! This service is offered to St. Peters residents for free beginning April 2019 through the end of September. The station opens to non-residents in May at a cost of $30 per vehicle.

Filling tires with nitrogen can increase your vehicle’s miles per gallon by as much as 2.5 percent, for an average savings of 15 gallons of fuel per year. Nitrogen-filled tires also last longer because they keep their pressure longer and do not have the extreme fluctuations in pressure that air-filled tires experience.

This service is offered by appointment only. St. Peters residents with a current Resident Privilege Card may schedule appointments either online at or by calling 636-970-1456. Non-residents can make their appointment by phone only, and the $30 fee must be paid in advance with cash or check only in person at Recycle City, 131 Ecology Drive.

Normal operating hours are 9 a.m.-3:30 p.m. Mondays and Fridays and the third Saturday of the month from 8:15 a.m.-1:30 p.m. Service is not available on City of St. Peters holidays, including the Saturday before Easter.

The tire-filling station is located at the HES Operations Building at 135 Ecology Drive, which is directly behind Recycle City.
