No need to switch load ratings for ST tires?
I'm getting a "new to me" 2012 Koala 21CS tomorrow. It has Goodyear Marathon ST205/75R14 C tires. I know a lot of folks are either wanting to go up in tire size, or at least in load rating. I u...

If you can find something like this on the tire "maximum load xxxx lbs AT yyy PSI(cold)" then that are the data I need to fill it in in my Traveltrailer-tirepressure calculator.
Then make shure the GVWR you mentioned is the real GVWR , as discussed already.
The C at the back probably means C-load wich is in America 50 psi reference-pressure, wich is not the maximum pressure, But if GVWR is right you dont need that much . A highening up can be better because of the ST tires wich are calculated for more deflection of the tire wich they may have at lower speed of 65m/h. But it would be better to handle it the same as an LT tire , if you have the reserve you have. This makes the advice higher.
So give the data , and I will calculate.
If you want to try yourselves, download by RICHTclicking on the newest version of my Calculator in next map on my skydrive.
