have a 33fk Zinger
tires 225/75R15D
tires I find are rated 2540# giving me 10,160# load rating
trailer dry 8140
axle rating 6900x2
this will put me at near max. when loaded
thinking of upgrading to E rated tires but what are your thoughts?
Looks like you will have about 2K lbs worth of stuff, including propane, water, and added accessories by your numbers. You will prob never exceed your axle limits (what's the rigs GVWR?). When you figure in your hitch weight you will probably be fine with D tires. you could go up to E tires when the D's wear out.
Beamer5 and Stan thank you for your input. I was thinking along these same lines but still had questions and yes I will wait for tires to show wear then replace. Just that we will be going Edmonton Canada to Phoenix and did not want on road problems as DW gets crankier when problems arise and I get (well you know, oil and water).
