New trailer tires

I have a 2012 Cherokee grey wolf 28bhks. The sticker on the side of the trailer states a size of st205/75d14 c. Is that a good rating for a 7700lbs gvwr?

Nope. They put the absolute bare minimum spec tires they can get away with on all campers (except maybe Airstreams). They will probably last a season or two, depending on how much you travel. Always go up at least one load range rating when replacing your camper tires. Two ranges if your rims will support the increased air pressure.

What information is contained on the side of the tire? Based on your description it is a Load Range C, which will usually have a maximum inflation pressure of 50 psi, and a weight capacity of 1,760 pounds (from Tire Rack - Power King Towmax). Etrailer has a Load Range C with a online spec of 60 psi and a weight capacity of 1,925 pounds (Karrier brand tire, but rim associated with that tire has a load capacity of 1,870 pounds.
If you assume a tongue weight of 700 pounds, that leaves 7,000 pounds spread between 4 tires. If everything is perfect (which never happens) that is 1,750 pounds each tire. Most trailers have more weight on one side.
The above assumes you would load to max GVWR. How much does it weight empty?

I just bought 4 new Goodyear Endurance 215/75-14 LR D that are rated for 2200 pounds. These replaced some Castle Rock 205/75-14 LR D, rated at 2040 pounds. The aluminum wheels still have a load rating of 2040 pounds, so all I did was make myself feel better about the tires.
I have not been able to find 14” wheels with a rating over 2040.
Do you have enough spacing to fit 15” rims/tires?

Maybe FR has improved. My Grey Wolf, fully loaded under 5000 lb, came with load range D. Yes they are Constancy Chinese made and we will see how long they last, but with four tires they should easily hold the weight. Each is rated at 2040 lb.

I bought my 2012 Cherokee grey wolf 28bhks used in Jan of 2018. Used the trailer only 2 times last year, do to my 7 month cancer fight. The previous owner put on st215/75d14 tires, don't know if it's a c or d load tire. Sorry I'm somewhat of a noob when it comes to trailer tires. So I thought that, the size of tire on the trailer now was the wrong width. I also figured that the RV company would put decent tires on their trailers at manufacturing. But after reading all the posts about tires, my assumption was wrong. So now I'm deciding between a radial st215/75r14 c rating or a bias ply st215/75d14 c rating. Can someone please tell me which is better, radial or bias ply? Any help would be appreciated.

A radial will run smoother and cooler than a bias ply, much better, get the D rating tire, looking at the last post the grey wolfs have been switched to the stronger tire, I know my new Cherokee came with E rated tires, and only 3 years ago the came with D rated, I think they’re trying to address some problems and upgrade some trailers
