Jeep Lungs

What do you guys think of these there supposed to hold air. And be stronger than most rocksliders. Set puts ya back about 700 for two and everything you need to air up and use the air.

Apart from the vulnerable location I doubt they hold enough air to fill 4, 33x12.50s.

Bolt an old scuba tank to a roll bar. 80cuft of air. If you are a firefighter you probably have access to an SCBA compressor.
