From Road to Trail VIAIR's battery powered air compressor pumps are loved by daily commuters, families, and extreme off-road enthusiasts alike for their powerful, reliable performance in a small package. 12V Battery Clamps for Higher Performance Offroading applications have higher performance demands that cigarette lighter plugs are unable to meet. Enthusiasts prefer direct battery connections for their trucks, Jeeps and 4x4s because it accommodates the increased current draw of larger, more powerful compressors. While VIAIR does offer cigarette lighter models, we recommend compressors with battery clamps for serious for offroad use.

## Questions & Answers

**Q: how long will it take to pump 4 off  265/75/16 from 15psi to 60psi**
A: My tires are 285/75R16 and it takes about 4 minutes to air up from 30 psi to 65 psi (each tire). So, about 16 minutes for all four. The run time is 20 minutes per hour, so no cool down is necessary with the 400P model.

**Q: Can it fill 5th wheel tires to 110 PSI  ST235/85R16  (G)**
A: The specifications on the manufactures website says the max working pressure of the 400P is 150 psi. Please note the 400P has an 8ft power cord and 25ft air hose. Depending were you will receive power from, you might want to consider also purchasing the 30ft extension hose. Viair part number 00030.

**Q: I have 33x12.5.15 inch General Grabber offroad tires, will this compressor work well?**
A: I also have 33x12.5 off road tires that I air down on the trail and use this compressor to air them back up. It works well and it is quick.
