I'm glad you brought this up....I never have asked about this either but have wondered, so if any of you have experience with bleeder valves let us know. I have a set of four still in package....I think afco....but have always heard the same crap you just mentioned so I've never used them. Have any of you found them to work properly and is it worth the effort?

I have run air bleeders before and had some good results, but occassionally they do not seat well and the air goes lower than it should. You have to put more time in adjusting and checking. If they work then they can have a slight edge, but when they fail you lose. I have gotten pretty good at setting and predicting tire pressures so that I no longer use the bleeders.

another alternative is to use hydrogen gas to air the tires up. It's what aircraft use because it doesnt expand or contract under heat or cold temperatures. It's gunna cost money but if you're tires are the same from green to checkards and you bring home the $$$ then it does pay for itself. Also if you're going to use hydrogen make sure you have good wheels that seal the tires up, dont wanna be wasting that stuff with leaky tires.

If you want to have a bunch of flat tires use bleeders, Thats what I learned about them the hard way.

I got a set of the kwik change bleeders for this year and after playing with them a bit found that they can bleed down all the way. This scared me so i never put them in. The nitrogen works pretty good for keeping it from growing more than 1 pnd or so.

For years we used the cheap bleeders from speedway motors with not one problem. Then 3 years ago we switched to the kwik change bleeders and NOTHING but trouble.

Here is my thoughts, After useing them for the last 12 years they are like any other part on a race car. They need to be inspected and cleaned. The Kwik change bleeders are EXTREAMLY high work, must be taken apart every night to be cleaned inside and what you clean them with make a HUGE differance. Because all bleaders use some type of rubber to seal only clean with soap and water. They should also be covered while washing the car. I gave away all my kwik change bleeders and went back to the cheap ones, we keep them dry while washing the car and don't adjust them too much. We take them apart and clean them at mid-season and NEVER have a tire go flat. One other thing about the cheap ones.....you can put a small machine s,crew in the center to shut off the valve........if you feel it's leaking and you will get a flat. You should always use a s,crew to shut off the valve while trying to get the bead of the tire seated when you change tires on that wheel, if you don't the high pressure will damage the bleeder and this could make it stick in the future.

They are NOT black magic, they are a nice effective way to help keep the set-up from changing during the race, but do require some work.
