Ram ProMaster Tire Pressure (PSI)
Recommended tire pressure for Ram ProMaster commercial van. Pressure varies significantly by load. Check door jamb sticker.
| Model | Configuration | Front PSI | Rear PSI | Load Type |
|---|---|---|---|---|
| 1500 (118" WB) | Standard Roof | 55 | 80 | Unloaded |
| 1500 (136" WB) | Low/High Roof | 55 | 80 | Unloaded |
| 2500 (136" WB) | Low/High Roof | 65 | 80 | Unloaded |
| 2500 (159" WB) | High Roof | 65 | 80 | Unloaded |
| 3500 (136" WB) | High Roof | 70 | 80 | Unloaded |
| 3500 (159" WB) | High Roof | 70 | 80 | Unloaded |
| All Models | Fully Loaded | +5-10 | 80 | Max cargo |
Commercial Load Note: ProMaster tire pressure is CRITICAL for load capacity. Always inflate based on actual cargo weight. Rear should stay at 80 PSI for most loads. Front increases with weight.

ProMaster Quick Tips
Common Issues & Maintenance
Commercial Use: ProMaster requires more frequent maintenance for commercial/delivery use. Halve all intervals if driving 20,000+ miles/year with cargo.
Suspension: Front MacPherson struts wear faster under load. Inspect at every tire rotation. Rear leaf springs rarely need service but check shackles.
Brakes: Front brakes wear significantly faster due to weight distribution. Expect replacement at 25,000-40,000 miles for commercial use. Use quality pads rated for vans.
2025 ProMaster EV: Electric model offers 162-mile range with 6,910 lb payload. Battery warranty: 8 years/100,000 miles. Requires Level 2 charging (240V).
Cargo Weight: Always distribute cargo evenly. Never exceed GVWR. Check tire pressure monthly or before heavy loads. Overloading causes transmission failure.
Cold Weather: ProMaster has large cargo area that affects heating. Engine block heater recommended for temps below 0°F. Keep fuel tank above half in winter.
