Single axle X1 trailer with Goodyear Marathons. Tire sidewall says max load at 65 PSI. Is this what I should put in it? I don't even have a gauge that goes past 50 psi!

I could have swore the max was 50?

Well, I'm off to get a new tire gauge. Footin, some sizes are only rated for 50 PSI. See bottom of page 9: http://www.goodyearrvtires.com/pdfs/tire-care-guide.pdf

Mine are the 225 75R15s, sure enough, max load is at 65 PSI, and 45 PSI is marginal at best for the load.

I inflate my Marathons based on the load, expected highway speeds, etc.

I'm sure "thatsmrmastercaft"/tire expert will chime in and enlighten us!

In the interim, here's a couple of articles/fact sheets that discuss this...

As per the Goodyear recommendations I run mine at 65psi which is 10 psi above what is stamped on my 14" tires. I tow fast.
