Thank you.

Good job of getting the "Real Weights" Too often folk simply drive on a scale and divide by 4. In your case you would have thought you had 3009# on each tire. Instead you know that you are off by 7.4%. You didn't say what size tires you have on the trailer but with a tandem axle I recommend you run no more than 90% of the published "Dual" load and to always run the pressure shown on the tire sidewall. If you have ST type tires you need to consider 65 MPH like the Red Line on your engine. It's possible to run at or even above the red line but not for long and you can expect much shorter engine (or tire) life.

We're running Goodyear 614 and I have been keeping them at 105 PSI, I will take your recommendation and take them up to 110. We run 60-65 mph to save fuel. We have about 12,000 miles on the this rig, and this summer we had the MOR/ryde IS and disk brakes installed.

Cthns,

You see lots of overloaded 250's towing Montana and similar size 5ers.

Airbags will help you ride level but don't change your weight ratings or help you stop. Bummer, you need a bigger truck. Been there and been as surprised and dismayed as you when I found these forum topics.

Your biggest risk exposure is overloading the rear tires and maybe the rims. If you keep the truck, definitely fix this!

Good luck.

The bank and I bought a ..........

2012 Chevy 3500 CC Short bed Diesel SWD with Allison transmission. We are looking at full timing down the road. Is there a standard form to determine weights and pulling capacities.
I have read that Chevy rates this truck to pull 17,400 lbs.

Someone give me a web site or printable form to determine weights and pulling ratings.

We are looking at 39 ft 13,400 dry..16000 GVWR..2480 hitch weight..axle weight 10,920
