My guess is Load range C tires, max load pressure should be 50 psi.
When taking delivery of our brand new Coleman TT, a couple of months ago, the dealer (Camping World), handed me a sheet, 3 columns of items/systems they “checked”. One item was tire pressure and written in was “inflated to 65 psi”.
I towed it home, about 90 miles. Got to thinking about the tire/load sticker on the left front of the trailer. It states Load Range C tires, max load 50 psi. Confirmed by looking at the tires.
So I checked, looking for 65 psi. First tire read 35. The rest were between 35 and 40. Luckily the trailer wasn’t loaded. Had I not checked, loaded up and left on a trip... Probably not good.
I had a “chat” with the salesman concerning the issue.
