Since the 2150 relates to the 225/15 tire at 50 psi I would get new wheels.
Probably Ok at 65 psi but I am not recommending it.
2540 would indicate D
2830 would indicate E

Thanks for the info. I've never had that happen. Probably because I've only had small ST205/75R14 LRC tires. my new trailer, Jayco 23RB, came with ST205/75R15 LRD tires.2112 wrote:Atlee wrote:It was bouncy. Over reacted to every bump in the road.

How do you know it rode hard at 75 psi? Obviously, you can't be in it to know it rode hard. Was it because cabinets were open, and stuff on the floor when you stopped? Was the harsh ride somehow transmitted back to your TV? Did you have a CCTV giving you a picture of what was happening?
I certainly couldn't tell when I changed from C to D tires.2112 wrote:

I ran them at 75lbs and they rode hard. I lowered the pressure to 65 and it is back to normal. I'm happy with my new GY Endurance. Money well spent.

So if you have ST or LT that are load rated, you can safely run lower pressure based on the weight carried. Course that means a trip to the scales to verify weights.

This is a really interesting topic but I'm a little confused.
When I got new GY Endurance tires while on the road after a blowout, I assumed the GY dealer would put the proper tires on, at least C or maybe D. I didn't think to ask (my bad I guess). The dealer put E rated tires on, and I believe my wheels are in the 2200 pound range (inflation pressure was 50psi) for an 8k trailer.
The E tires are clearly and prominently marked to be inflated to 80psi.
Is it the valve stems that are the real concern, or is the higher rated tire too strong for the wheel? Will the valve stem blow suddenly, or the wheel fracture, or an axle break, or what?
Not really understanding why the tire rating matters(as far as the wheels are concerned).
Apologize if the answer is already here and I am just missing it.
