tire pressure

RV trailer tires need to be at max pressure. It is rare for an RV trailer tire to be grossly UNDERloaded, but not uncommon to be maxxed out, or overloaded.

Run the pressure up to the max!

This!

Yes, the specification for load range D is 65PSI.

Thanks guys, I know there's been a ton of items on this subject, 65 psi it is!

I have always run my trailer tires at maximum sidewall pressure and have never had a single tire related problem. I would recommend you run yours at 65psi.

I have two main reasons for saying that.
1. Most trailer tires are just adequate for the load they are carrying. There is usually very little capability to spare.

2. The higher pressure will make the sidewalls stiffer which helps keep sway down and also helps keep the tire on the rim when doing tight turns that scuffs the tread along the road. This does not happen on single axle trailer but most travel trailers of any size have two or more axles and will scuff the tread when turning. The bigger the spread between the axles, the more scuffing will take place.

I'm looking at Towmax load/inflation chart in front of me right now. That is the max psi and rated for 2540 pounds. Don't know about other brands. And don't know about your weights.

I would probably trade them for a set of Carlisle HD tires in load range E and run 80psi.
