Question:

I have a 2019 Apex Nano travel trailer. The factory max load is just under 4000lbs. What pressure should i run for highway towing? The side wall rating says the max is 65psi cold. Right now i have 54psi in the tires cold. The tires are your 205 75 R14. Thank You

Expert Reply:

Since the tires you have on your 2019 Nano Travel trailer are similar to the Westlate ST205/75R14 # 274-000012 that get aired up to a max 65 PSI, you will want to air them up to that max.

Trailer tires have a thicker sidewall as they are designed for the tire to always be aired up to the max pressure. Not airing them up all the way causes excess heat to build up in the tire which can lead to decreased tire life and other issues such as blow outs.

I included a video of the # 274-000012 for you to take a look at.
