So how many tire will a little cyl. fill or top off?

Sam

i usually use the 5 lb cylinder for the jeep when we go off roading (since i don't have on board air on the Jeep Wrangler)....itll top up at least 8 tires. Ive since picked up a 10 lb cylinder for topping up the coach tires.

below are some numbers from powertank.com for a 10 or 15 lb bottle.
btw powertank & smittybuilt make similar systems that will run you 250-400 bucks.

in complete transparency - i rarely ever take the bottles with me anymore...every since i install my TST 507 Tire Pressure & Temp monitoring system i MIGHT have to touch a coach valve stem Twice a year, usually only once (when the temp gets cool).
