Nitrogen Tire Inflation Service Checklist

This nitrogen tire inflation service checklist ensures complete and properly executed nitrogen inflation services for passenger, performance, and fleet vehicles. Nitrogen inflation reduces tire pressure variation from temperature changes because nitrogen molecules permeate rubber more slowly than oxygen and contain no moisture. The purge procedure must achieve minimum 93% nitrogen concentration to deliver the advertised benefits. Aligned with Nitrogen Tire Inflation Service standards and TPMS co

Industry: Automotive Service / Tire Service
Frequency: Per New Tire Installation / Annually / Per Rotation Service
Estimated Time: 15-20 minutes
Role: Tire Technician / Service Technician

Compliance: NitroFleet Service Standards, OEM TPMS Compatibility Requirements, TPMS Relearn Procedures Per SAE J2657, Nitrogen Tire Inflation Service Industry Best Practices, OSHA 29 CFR 1910.177 Tire Inflation Safety

Pre-Service Tire and TPMS Assessment

Inspect tires and TPMS before nitrogen service.

All four tires in serviceable condition with adequate tread and no damage?
TPMS sensors present on all wheels that will receive nitrogen?
Starting air pressure recorded for all four tires before purge procedure?
All valve stems in good condition with caps present?
Nitrogen supply tank or generator confirmed providing minimum 99.5% pure nitrogen?

Nitrogen Purge Procedure

Execute purge to achieve minimum 93% nitrogen concentration.

Each tire deflated to approximately 50% of recommended pressure before first nitrogen fill?
Tires inflated to placard pressure with nitrogen after first partial deflation?
Tires deflated to 50% of placard pressure again for second purge cycle?
Final nitrogen fill to exact placard pressure specification after second purge?
Nitrogen purity verified at minimum 93% with nitrogen analyzer (if equipment available)?

Pressure Verification and Equalization

Verify all tires are at correct and equal pressure after nitrogen fill.

All four tires at exactly the vehicle placard specification pressure?
Spare tire inflated with nitrogen if accessible full-size spare?
Green nitrogen-service valve caps installed on all serviced wheels?
TPMS reading correct pressures after nitrogen fill (relearn if needed)?
Soapy water test at valve stems confirms no leaks?

Customer Education and Documentation

Educate customer on nitrogen benefits and maintenance requirements.

Customer informed of nitrogen benefits (slower pressure loss, reduced oxidation, less moisture)?
Customer advised to use nitrogen for future top-off inflation to maintain purity?
Customer advised that adding air in emergency is acceptable but reduces concentration?
Customer advised to check nitrogen tire pressure monthly despite slower pressure loss?
Nitrogen inflation service documented with tire pressures set and purity level achieved?
Customer informed that green caps indicate nitrogen and should be told to any shop performing tire work?
Annual nitrogen purge and refill service recommended to maintain optimal purity?

Nitrogen Maintenance Plan and Service Record

Establish nitrogen maintenance schedule and document service details.

Customer advised nitrogen top-off is complimentary at this shop to encourage return visits?
Next nitrogen purity check and potential purge service scheduled (annual or 12,000 miles)?
Nitrogen fill to be included at all future tire rotation services?
Green nitrogen valve caps ordered and in stock for future top-off services?
Nitrogen inflation service properly invoiced with per-tire or set pricing?
Nitrogen service noted in customer account for future technician reference?
