Ours certainly do but with the tag dumped there is likely only about 500 lbs on the tire so wear is minimal and will not kill the tire before time.

There is no " down Force" on a tag set up, or maybe that's what you mean by "0" ., the tires sitting on the ground, not lifted. ? Air pressure in the air bag increases or decreases weight transfer to the axle, I.E.: tires on the pavement.

There is a downforce. Mine is set for 28psi per owners manual. What is yours set at?
Heavier rigs are set at 100psi or more.

The only intelligent answer on this thread, the Op is probably so confused by now he'd wished he didn't ask, lots of guessing here....

Tag bag air pressure gauge ? Not sure but the psi rating gauge or digital readout as in my coach computes tire psi by using the amount of air in the bags. At lest that is what I think is happening, as that is what the manual says as well as the dash heading " tires" .....Same for " front" ( steer ) and "rear"( drive) read outs. Many semi trailers have this system installed that use air pressure ( psi) in the bags as a way of determining axle weight and or overall wt. load on trailer. It's not as accurate as a scale but does help the driver determine load placement while loading.

Regarding lifting of the axle , it takes another set of air bags to do the lift, if you do not have these than the tag never really leaves the ground. This issue gets compounded when with 0 gague readings only shows empty airride bags. Some states will only charge tolls if the tag or pusher tires are on the ground , which is hard to see from a toll booth I'd there is only a 1 or 2 inch lift. Other states do not recognize lift axles, only the number of tires that " should" be on the ground. In my case the axle actually lifts as well as dumps, it's all automatic, driver has no control of this.

Since the OP gave a vague description of the problem without pictures it is all speculation and guessing. Obviously if there are enough guesses with a broad range of answers someone will come close to the correct diagnosis.

The shotgun effect ! Sometimes that's all we can do, or get , like you said. The other benefit is we all learn a little more how things work by all the experiences expressed here. The thing I hate the most when there is a problem is not knowing how things work and why, drives us often to speculation , not always a good thing.
