ActivAir FAQs

What compressor can I use? Can I use the compressor for other components (diff locker)?

To have the best inflation performance, choose a compressor with high CFM and duty cycle. Check the minimum pressure required by other pneumatical equipment before using the same compressor. Compressor pressure can drop to 10PSI when CTIS inflation is in progress.

Can I have ACTIVAIR on my rig?

Currently compatible with Jeep JK, JL, and JT. More to come soon.

What wheel do I need to use ?

ActivAir is compatible with Run Flat International beadlock wheels.

What BFG tire size do I need to use?
