Thanks for the assistance folks.
The best I can tell you on the weights is the rig runs around 15k (depending on how much water/wine we carry). I run 95-100 lbs of pressure in the tires, checking before every run, no matter how short or long.......
Good for checking the pressure before every run.
If I do the math, at 95 psi, the tire is rated for 3415# at 95 psi. Times 4 = 13,600#. If the weight on the tires is 15K, that would be 10% overloaded - on the average.
If 15K is the total weight of the trailer and we subtract 15% for the load on the tongue, then the tires are averaging 91% of the rated load - and that doesn't take into account side to side or front to rear variation. This sounds pretty marginal to me.
And that doesn't take into account the 15% reserve capacity I think all tires need to have.
Overall, I'd say you need to get the trailer weighed - tire by tire if possible.
...OR, look at the placcard on the rv and see what is recommended cold psi for the tire IF OEM tire...
The G614's on my 5er (GVW of 16,950#), run at 110 psi ..That's what 5er manufacturer recommends as well as Goodyear on "my" 5er...Sometimes weighing each tire isn't realistic, unless one has the time and knows where to go to get this done...IF tires are OEM weight rated and size is correct, at the very least, run at max sidewall psi rating. (110 on the GY G614's). I've had one tire failure on a GY G614 on sig 5er, loaded to 16,000# and that was due to a weak spring pack that took the tread off the tire..never lost air..Those tires were original tires that came on my 5er, manufacture date of 0606 (6th week of 2006)...tire was 4 yrs old and again, tire didn't fail, spring pack on that tire was sagging
terribly.
Just saying if one doesn't have the time or resources to weigh each tire then go with max sidewall pressure IF tire is OEM size and weight rating. I've been towing since 75 through the mountains of WV, TN, NC, SC and VA and the above incident was the first and so far only tire issue I have had and I ran tire at manufacturers recommended psi rating
