Any recommendations for PSI for 11fk being pulled by Sienna Minivan?
There should be a tag on the frame that lists the PSI.
Otherwise use the inflation pressure on the tire sidewall.
Be safe.
I would recommend checking the tire itself for max pressure no matter what. We just had a case on the forum where the tires on the trailer were not stock and so the sticker on the trailer advised a much higher pressure than the rite could take.
The pressure listed is also generally the max pressure rated not necessarily the recommended pressure. Max pressure is really only needed if you are near the max weight limit of the tires. Ideally the tires should be inflated to a point where the tread contacts the road evenly. This pressure will be different depending on the weight of the trailer, and air temperature. The pressure also changes depending on if you've been driving. My rule of thumb is to start high and let air out as needed.
[p]As Sean and swilky (indirectly) point out, if you don't have the original tire size and load range, to be safe and to get the right tire contact for good performance and wear, you have to do the following:[/p][p]
[/p][p]I assume that any new non OEM spec'd tires have a larger size and/or load range than OEM. If you are using less then you are probably unsafe at any tire pressure. Just using the sidewall pressure can result in less tire contact patch than is optimal, particularly if you have larger and/or higher rated tires than OEM. Generally if you use the trailer sticker tire pressure you will be ok, even if it is less than the sidewall pressure.
