Nitrogen Tire Inflation Service Checklist

This nitrogen tire inflation service checklist ensures proper purge, fill, and verification procedures for nitrogen tire inflation service. Nitrogen-filled tires maintain more stable inflation pressure due to nitrogen's larger molecule size and reduced permeability through rubber. Aligned with Tire Industry Association nitrogen service procedures, NitroFill and other nitrogen system operation guidelines, and vehicle OEM tire inflation recommendations.

  • Industry: Automotive
  • Frequency: Per Nitrogen Fill Service / Quarterly Pressure Check
  • Estimated Time: 20-30 minutes
  • Role: Tire Technician / Quick Lube Technician
  • Total Items: 28
  • Compliance: TIA Nitrogen Tire Inflation Service Procedures, NitroFill Nitrogen System Operating Standards, OSHA 29 CFR 1910.169 (Compressed Air, Gases), Tire Pressure Monitoring System (TPMS) Requirements, SAE J1634 Nitrogen Inflation Standards

Pre-Service Tire Condition Check

Inspect tires before nitrogen service. Damaged tires should not receive nitrogen service without addressing underlying issues.

  • All tires free of visible damage, cuts, bulges, or embedded objects?
  • Current tire pressures recorded before service (cold readings)?
  • All valve stems in good condition (not corroded, cracked, or leaking)?
  • Tread depth adequate for nitrogen investment (minimum 4/32")?
  • TPMS sensors present in all positions and functioning?

Nitrogen System & Purity Verification

Verify nitrogen purity and system condition before inflation. Low-purity nitrogen provides minimal benefit over air.

  • Nitrogen generator/cylinder providing minimum 93-95% nitrogen purity?
  • Nitrogen generator membrane filter in good condition (within replacement interval)?
  • Nitrogen supply pressure adequate for filling to required tire pressure?
  • Fill equipment connectors and hoses clean and free of moisture or oil contamination?

Purge & Fill Procedure

Proper purge procedure removes air (21% oxygen) and replaces with nitrogen to achieve target purity in tire.

  • Tires deflated to 5-10 PSI before purge fill (for conversion from air to nitrogen)?
  • Double purge procedure completed (deflate-fill-deflate-fill) for new conversions?
  • All tires filled to OEM placard specification pressure?
  • Final pressure verified with calibrated gauge - all tires within 1 PSI of target?
  • Green nitrogen valve stem caps installed on all four tires?

Documentation & Customer Instructions

Complete service documentation and provide customer with nitrogen maintenance instructions.

  • Nitrogen inflation service documented on repair order with final pressures?
  • Customer advised: use only nitrogen for top-off (or use air in emergency only)?
  • Customer advised of quarterly pressure check recommendation despite nitrogen stability?
  • Nitrogen service card or window sticker provided to customer with service date and pressures?
  • Customer informed of nitrogen top-off availability at future service visits?
  • Customer advised that TPMS warning still means check nitrogen pressure immediately?

Nitrogen System Maintenance Records

Track nitrogen system maintenance to ensure consistent purity output.

  • Nitrogen generator last service date within manufacturer interval?
  • Nitrogen purity log maintained with daily readings?
  • Nitrogen supply (cylinder or generator) adequate for today's service needs?
  • Adequate supply of green nitrogen valve caps on hand?
  • Customer shown nitrogen pressure stability data vs regular air to justify service cost?
  • Nitrogen service documented on repair order with purity level and final pressures?
  • Customer reminded nitrogen does not eliminate seasonal pressure loss from temperature change?
  • Next nitrogen top-off service interval noted (typically at each tire rotation or 6 months)?
