I have 3 of these cheater tanks and they work good on some things like new tires that stand up when the machine is jacked up. ALot of tires like trailer tires or a spare truck thats not moved and has a flat the tire is so wrinkled that it wont seat. THey also wont seat a some stiff new tires. I cant seat my skid steer tires with the air tank as they have rimguard beads on them.
One reason I use ether is that when a truck gets a flat onthe side of the road and here we dont have any shoulders. I can park a service truck run an air line to the tire and then ether it and be gone till the truck can get to a better spot.
With the CHeater tank your about 2 to 3 feet further out in the road. I had to use either this morning on a truck tire. The tire wouldnt take with the air soe we gave it a small squirt.
