I agree with CapriRacer. However, I would like to hear from someome who actually weighed each tire, to see how much weight is evenly or unevenly distributed. I have my doubts there is much variation. Just my $0.02.

Then this thread awaits your scale tickets.

We all have different TV, TT and payload.

Here are some actual Trailer weights submitted by some of my blog readers.
A Tot B Tot C Tot
LF 2840 2240 1750
RF 3230 6070 2240 4480 1484 3234
LR 2780 1460 1870
RR 3185 5965 1360 2820 1304 3174
F L/R 47/53 50/50 54/46
R L-R 47/53 50/50 59/41

Axle F-R
50.4/49.6 61.4/48.6 50.5/49.5


"F L-R" is the side to side balance of the front axle
"R L-R" is the side to side balance of the front axle

As you can see while some trailers have good (50/50 & 52/48) side to side balance they have 61/49 axle to axle balance
Other are good axle to axle at 50/50 they have side to side of 59/41

If you haven't had your individual loads measured with separate scales or if you haven't done a worksheet after doing the multiple weigh-ins you are only hoping you are not 39/63 or 59/41 and are overloading one or more tires.

RVSEF has a database of tens of thousands of trailers and it shows over 55% have one or more tire or axle overloaded.

Is this good enough for the skeptics?

Thanks, Tireman 9!

Besides creating more work, well . . . none of us knew that WD hitch set-up and concerns about tires would be as involving as they are. As they should be, it turns out.

Accurate weights

Getting accurate weights is a one shot deal unless you go and make some significant modifications to the RV. Get the worksheet, Load the RV fully and get the weights needed to do all the calculations.

Compare the results with the tire/spring/axle capability and try and adjust if needed or don't carry so much stuff.

RVs with slide-outs or with generators and water storage on the same side seem to be real bad actors. Sometimes the RV mfg makes an effort to balance the unit but the owner can still create unbalance by putting their heavy tool box and bowling ball collection :-) on one side or having the hitch or pin high or run with improper load distribution hitch settings.

The final items are to be sure your pressure gauge is accurate. I have posted results of my tests on my blog.

And treat the speed limit (65 on ST type tires) 75 on almost all others. as you do your engine red-line. You don't run at red-line all the time and possibly never as you know that damages the engine. Running 60 - 65 on ST type tires is similar to running just under the engine limit. It's not good for the long term life of the tires.
