What is the consensus on Goodyear Endurance cold tire pressure? Running them on a Ranger Z520c and the trailer says max 50psi and I know the tires can handle up to 65 PSI? They are currently set at 55 psi.

I run 55 and like yours the trailer says 50. I think either is fine.
Guessing the original tires had a lighter load rating with a max psi of 50 maybe. Personally, I follow the psi rating on the tire and run 65psi in my Endurance tires.
65 is max pressure. Look at your car tires. They are rated for more pressure than what is recommended by the manufacturer of the vehicle. If you put max pressure in a vehicle it’s going to ride like a tank. I bought new tires for my Tahoe. They over inflated them at the tire shop. When you hit a bump it would rattle your teeth.
Original tires were rated for 50psi max and you changed to a 65psi max tire, so you can't really go by what the trailer says. You'll be safe at different psi but I like to adjust the psi until you get a good ride on the trailer. With new tires, I like to start a little high and try them and then start lowering the psi until I'm happy. If she's performing good at 55psi, you're good.
Between 60 and 65PSI. Since the majority of trailer tire failures are due to underinflation, I keep mine within 5 PSI of the maximum pressure to get the max load handling. Also, there's less rolling resistance at higher inflation and that helps fuel economy.Originally Posted by paulrodbender
Tire guy told me 60 to keep wear down rather than the 50 stamped on the trailer for a Cl. C tire.

There's a formula on Goodyear's website and a couple of other trailer tire manufacturers to set the inflation based on the trailer load rating, not the load rating of the tire.
The Endurance that I put on my camper had a max of 80psi and that's where Discount Tire inflated them. The trailer bounced around all the way home and cabinet door were open and drawers messed up. Ran it at the 65psi that the trailer manufacturer called out and they have been fine for the past 3 or 4 years.
Goodyear has a chart for the correct pressure for the Endurance tire and it is based on top speed(87 mph is the max) and the load the tire is carrying. I have tried to upload the chart, but I don't have the knowledge needed to reduce the JPEG size to upload it. You can Google the chart. The title of this chart is: LOAD/INFLATION INFORMATION FOR GOODYEAR ENDURANCE SPECIAL TRAILER (ST) TIRES.
A note on the Goodyear chart mentioned above. The load limit listed is per tire and is additive. If the load limit listed is 1500 pounds for a tire, and you have two tires on the trailer then the total limit (as far as the tires are concerned--the trailer and other components have to rated for this weight also) is 3000 pounds. If four tires are present, then the four tires together are rated to carry 6,000 pounds. The load limits are based on the tire pressure. So, I guess that to inflate to the proper pressure you need to weight the boat, and divide that weight by the number of tires on the trailer. That would then be the load that tire will be carrying. Then find that number (load) on the above chart for the model tire that you have, and locate the appropriate tire pressure. Beginning to sound too complicated. More tire pressure to a rated max equals more carrying capacity. It seems you can lower the tire pressure to meet your needs as to smaller carrying capacity. I would check this out with an expert--don't take my word for this please.
Thanks all. I have seen the chart by Goodyear but it never really made sense the way it’s presented.
While tire pressure is obviously most important, I’d also recommend balancing the tires. A few of the bigger tire shops won’t balance trailer tires. They will perform better and last longer if balanced.
I have a single axle trailer with ST225 E rated tires. They are inflated to 65 PSI cold. The load carrying is 2540 x 2 = 5080 lbs.
This recommended inflation information is provided by the Engineers at Goodyear.
