Want to know about GVWR AND GCWR?

This is for those that want to use their truck like a truck and haul stuff that wont fit in the bed and the stuff that does fit in the bed

BASICS

GAWR= is the maximum distributed weight that may be supported by an axle of a road vehicle

GVWR=The Gross Vehicle Weight Rating. Typically you can find this sticker on the door

GVCW=The Gross Combination Weight Rating is the total allowable weight of the completely loaded vehicle and trailer

Tire load rating=The max weight limit PER tire

If your GCWR (trailer's WR +truck's GVWR) = over 26001 you NEED A CDL



This is for newer GM trucks but it carries the same Basic ideals for safe towing

Your GCWR is biased off your engine/transmission and rear ratio combination. this means if you have a 4.3 with a 3.08 and auto trans your GCWR would be 8,500 lbs vs a 5.7 with 3.08 and auto it would be 10,000 again this is for the 88-98 style trucks but it should give you an ideal of where you should be. most the numbers are to keep your engine/trans cool and not cut their life short by working them too hard
