The sticker weight ratings aren't as important as an actual scale weight. For my trailer, the GAWR is 3320lbs, GCWR is 3500lbs; fully loaded scale weight is 2400lbs.
When I had the radials on my trailer, the tires were way under the GAWR/GCWR numbers but barely OK based on the scale weight (I had about 200lbs headroom). In this case, the tires were the limiting factor. My new bias tires exceed the GAWR/GCWR so the axle & suspension are my limiting factor.
If you're concerned, go get it weighted at a truck scale and use that number instead of the sticker numbers. Best is to scale when loaded for the longest trip expected with full water, propane, food, etc.
