Tire Pressure for trailer tires

[BrianNeil]

Is there a recommended tire pressure for trailer tires?

[donald]

Yes!
Depends on the weight you are putting on them! Ck side wall for Max pressure and weight rating! DO NOT over inflate or overload!!!!!
Ck weight of total load including trailer, you should be under the stated tire load rating!
2 tires with a rating of 1500lbs equals 3000lbs max!

My 2000 Maxum 1800XR has been on its trailer garaged all Winter. I'm assuming the tires will need air, just wondering if I will get accurate readings with the boat on the trailer. I guess its no different that the readings for car tires

With cars the max pressure on the sidewall is not the recommended pressure. The recommended pressure is usually printed in the drivers door jam and is almost always less than the max. pressure printed on the sidewall of the tire.

So those using sidewall max. pressure are over-inflating.

I would be under the max. tire pressure on the sidewall to be safe. this is just one person's opinion.

Good morning Srew!
The OP wanted to know what pressure to put in his trailer tires! I was just trying to give him a base to go on! But yes you are correct as to that not being the recommended tire pressure!
For trailers I go with the max recommended pressure on the sidewall as trailers usually carry more weight on the tires than cars!

When I purchased my 2005 2200 SR3, during the "new owner" orientation, I was told to keep the trailer tires at a "hard" 50 psi. I have a karavan tandem axle trailer. I have had good experience running them at that pressure. I hope that helps a little. Note: I do believe 50 psi is the recommended as well, as listed on the side wall.

I wasn't trying to contradict you. If anything I think I was trying to supplement your statement.

You are absolutely correct. The pressure is determined by weight. The tire dictates the max. pressure based on max. weight. If anything I was simply trying to clarify a very common misconception that sidewall pressure only dictates the limits of the tire, not the recommended pressure setting for the vehicle (or trailer).

If I used the max tire pressure value on any of my vehicles I would be WAY over the recommended tire pressure for that vehicle. That gives a harsh ride and leads to improper thread wear on the tire.

Good morning Shrew! No offense taken!
We are all here to help and learn, some of us (me) learn more everyday!
Everyone out there has knowledge that others do not!
Thanks for all the learning experiences from all!
