St. Peters’ Nitrogen Tire Station Opens April 1

Want to increase the miles per gallon you get by as much as 2.5%? That is what can happen if you replace the air in your tires with Nitrogen.

St. Peters residents with a Resident Privilege Card may get nitrogen in their tires at no cost from April-September. Non-residents can use the service for a fee of $30 per vehicle from May-September.

This service is offered by appointment only. St. Peters residents may schedule appointments either online at or by calling 636-970-1456. Non-residents can make their appointment by phone only. The $30 non-resident fee must be paid in advance. Normal operating hours are Monday and Friday and the third Saturday of the month. The tire filing station is located at the HES Operations Building at 135 Ecology Drive which is directly behind Recycle City.

Based on EPA estimates, fuel savings for the average vehicle will be about 15 gallons per year. In addition to saving fuel, nitrogen-filled tires wear longer because the tires keep their pressure longer and do not have the extreme fluctuations in pressure that air-filled tires experience.
