The best upgrade for your TT

When I put new tires on my trailer, I went from C to D. The trailer was just below the max weight (by less than 200lbs) for the two C tires. When I put the load D tires on, I "felt" a smoother ride from the trailer.

Now, I was also more confident in the tires and that may have affected my "feelings",

I'm towing with a Durango not a 2500, and I tow in the mountains, so I do feel the trailer behind me at least some of the time.

I also always check air pressure before and during the drive and make sure the tires are properly inflated.

So perhaps it has more to do with upgrading from load C to load D tires than because "chinabombs are squishy" or "good tires track better" or it's just that the OP has more confidence in the new tires and that has colored their perspective.

Two of the used travel trailers I have bought were equipped with "P" Passenger rated tires when they clearly should have had ST rated tires.

Towed those trailers home 40 miles with only 35 PSI in the tires, trailer never felt "squishy" and they did not become "China bombs" even though the tires were so old that they had severe weather checking cracks deep in the treads and side walls.

Correct tires should have been LR C in STs with 50 PSI which is what I changed them to once the trailers were ready to go camping.

Never felt any "change" in trailer handling..

Tire dealer actually bumped my trailer tires on my current TT to LR D, didn't tell me that and i ran those tires at 50 PSI.. Kept wondering why I was having issues with the tires no longer wearing even.. Discovered the change, bumped up the pressure to 60 PSI and no more odd tread wear.. For the record, LR D has 65 PSI sidewall pressure but running a light load on that will result in ripping the center tread off before the inside or outside tread.

I have to be mindful of that with my 10K GVWR flatbed trailer which has LR E tires at 80 PSI but my loads are often well below the max load ratings of the tires.
