How do you know when your vehicle is overloaded

You mean net right?

 

mines perfectly legal at 60...AG100...just about 33500 on the drives.

 

LOVE IT! What's the weight on the drives when your gauge is at 105?

 

Ichudov , truck609 is on the right track. Back in the day a piece of chain was a common way to get a rough idea when you fully loaded. You said it was a spring ride truck so do what he suggested. If the trailer is spring ride also do the same thing. I'd have the chains hit the ground when loaded. Make sure the ground is as level as possible for this to be anywhere near accurate. If you only use the truck occasionally I wouldn't be buying load cells either. A more discreet way is to have your mudflaps close enough to the ground to hit when its fully loaded. It sounds iffy but it's better than nothing.

 

Somewhere around 60k, last time I weighed them that heavy it was at like 95psi and it was like 55,000.

Your right though, 60psi is the magic number for 34k with the KW AG100-400 & 460 suspensions. Getting legal with air ride is simple. 60psi is also 34k on Hendrickson Intraxx/HT300, it's 70psi for the Intraxx/HT 250 and also the 25k Neway and 80psi for the Intraxx/HT 230. These guys spending big money on special "air scales" amaze me when a $10 air gauge does the same thing. Hendrickson gives you the LBS to PSI charts online free. If your trailer is a spread and has the 30k suspension your about 68psi for 40k.

 

Thanks!

That's great information. I know mine, but appreciate that with a variety of set-ups you'd know the sweet spot on many.
