Tire Pressure for Parkliner

I bought my Parkliner in early 2014, so supposedly tire rub problem was fixed on my build.

I am getting ready for a trip and checked the tire pressure on trailer tires. It was about 32. Tires are the original HiRun ST205/75R14 which has a max load PSI of 50.

The problem is I can barely get my fingers between the tire and the wheel well. I'm wondering if the tires were purposely under inflated so they wouldn't rub. There are no rub marks on the tires, but I think if I inflated them to 50 psi, they would rub.

Any other Parkliner owners have this problem? Did Chandler say anything about keeping tire pressure around 30?

ParkLiner 34 was one of the units with the tire rub problem and Chandler's first and unsuccessful fix was to replace the original ST205 tires with LT185 radials. They are installed on the original rims. He mailed me new tire size/pressure stickers to apply to the camper which specify an inflation pressure of 60 psi, which is what I maintain. Since I had the wheel wells redone by a local body shop I probably have enough room to go back to the ST205s but the light truck tires are working well for us and run cool so I'm sure I will stick with them. I imagine you will have a heat problem running at 30psi

Brian, where is the tire size/pressure sticker located? I don't remember seeing one.

Huck,
On the curb side the sticker is located above the forward side of the tire next to the refrigerator access panel. On the street side the sticker is located above the rear side of the tire next to the electrical cord access door.

I looked earlier today. No tire stickers.

Chandler was not exactly a detail guy. I guess that's why we are owners of rare and limited editions.

Huck,
No stickers on our ParkLiner either and I know when we picked it up from Chandler l believe the tires were at about 50 psi.
Btw I too was a bit concerned about the amount of clearance in the wheel wells. I knew we had enough clearance for now but wanted to be sure we had enough for down the road when things wear and sag. Chandler let me pick the local shop for the inspection and also paid for the labor.
The shop checked clearance, alignment, and a few other items (can't recall w/o the invoice). They gave it a clean bill of health and even commented that it was one of the better quality trailers that they have had in in quite some time!

I found mine. Just barely above the battery box. I had to get on my hands and knees, put my glasses on, and shine a flash light on it before I could read it.

It does say 50 psi, so I will add some air and see if I still have enough wheel clearance.

Greetings Huck,
As noted by Brian one of Candler's "fixes" involved going to the LT185 tires.
At some point in your rig's future I highly recommend going that route.
On PL #35 the difference in ride/tow is noticeable. Waaay nicer than the original bias ply. We run 60psi in the LT185s.

A ST205-75-14 tire inflated to 50 PSI (maximum for this size) has a weight carrying capacity of 1760 pounds. The same tire, inflated to 30 PSI has a weight carrying capacity of only 1300 pounds. When I was running this size tire on my trailer I always inflated them to 50 PSI. If your trailer weighs 2600 pounds or less you would be OK at 30 PSI....but..I would try running at 50 PSI if at all possible. I think increasing tire pressure from 30 to 50 PSI would have a minimal effect on size increase but the only way to know for sure would be to try and test the clearance difference.

The 185R14LT is the same size used on Toyota Mini-motorhomes and some VW busses and Volvo station wagons, and it's profile is definitely narrower than the 205/75R14 versions.


In fact, if you mount the 205/75R14 size on dual mounts, they can made sidewall contact, where as the 185R14 has about a 1" of clearance. If there was a question, the 185R14, load range "C" or "D" will help. Yokohama makes a very nice version in the 360 LT series and there are also some trailer service versions out there.

As an FYI...Just checked the LT185s on PL #35...
Load range D / 1875lbs @ 65psi

Last trip to the scales heading out for a 5 day adventure with full fresh tank (15 gal) and all the trimmings... 2,350lbs

There is also a "C" load range available if that has enough capacity
