Spread axle vs. sliding tandem. Pros and cons

Don't you use an air guage on your axles and determine your axle weights from that????

 

not everyone has that fancyness...

 

A guage costs about $10.00 and overweight fines are ????? $$$$$$$$$$$

 

I have a gauge mounted on the side of my headboard for my drives.

 

Go buy an air gauge like the one on your dash that measures your brake pressure with a mount unless you have an area you can drill out to place the gauge in. Buy the brass fittings and the air line long enough to plum into the air suspension line. Cut the air line that feeds into the air bags and put a tee fitting (three way fitting), basically your splicing the air line of the suspension and the other end of the tee fitting you put the line from the gauge. And presto, you have your air scale. Next to figure the weight ratio, when you have a load on, go get weigh and see what the gauge reads, example, (72 psi on the gauge, and the scale reads 34,000 lbs, or 40psi on gauge and the scale might be 20,000lbs per axle or tandem), but you right the numbers down and you have an Idea. Did I lose you yet, cause I know I am.........

 

My company uses air scales, but they have to be calibrated every so often, and drivers tend to screw with them, I can usually get close to legal, but always use a cat scale over 30k pounds
