Max PSI rating on Trailer Wheels?
My trailer's Alloy wheels are 15 x 6, 5-lug. The load rating stamped on them is 2150 lbs. It came with 225-75-15, load range C tires, which run 50 psi. These tires are are marginal IMO for the trail...

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. My weight is 2k lbs per tire. My E is rated for 2840lbs at 80lb pressure. The D was properly rated for my trailer but I couldn't get GY Endurance in D.
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 recently went from LRD to LRE ST tires. The D max pressure is 65lbs and the E is 80. I'm running my new E at 65lbs. The weight of the trailer didn't change so why change the tire pressure. Select the tire pressure to the load placed on the tire.
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.
