Don't anthropomorphize your trailer - it doesn't like it.

The tire, wheel and the torsion axle on a traier are a "spring-mass system" similar to that on a car ( with the exception that there is no "damper", i.e. shock absorber other than some friction damping) that will respond to an unbalance in the rotating assembly.

Logic dictates that the rotating assembly should be balanced to prevent hammering the trailer chasis with a vibratory load and maintaining even wear on the tire. I don't know why any tire shop would recommend that trailer tires not be balanced and see no reason why Casita would recommend it except for the fact that no one sits back there to feel that load and complain about it.

I cannot believe that we are discussing such a DUMB subject. "Not ballancing a tire". Boy that is a DUMB subject. Have you ever passed your hand over the tread of a tire that has been run out of ballance? I can not believe anyone would recommend against ballancing a tire to be run at highway speeds or higher.

Unless things have change since I changed tires back in the 50's the red spot is where you are supose to line up the TIRE with the Valve stem on the Rim
THEN THEN THEN YOU BALANCE your tire'tires after inflating them but to US Old Timers that is just plain ole Blowing them up anim_wow.gif lol.gif

It takes quite a bit of unbalance to feel it in the TV. I had a tread separation start 100 miles from home, but didn't realize it. Just barely heard a oscillating sound when a back window was opened, thought it was that 18 wheeler nearby. No vibration. When I got home, a 3"x1" piece of tread was missing. That's what I heard. Of course I replaced the tire the next day.

I paid $7.50 each to have mine balanced, and now I can forget about it. Our new Casita now has about 7,000 miles on it, and the tires look great. Maintained at 50 psi cold and we don't exceed 65 mph.

Here is a 23 page tire care brochure on the Goodyear Tire site that addresses tire balancing for trailer tires. On Page 14 they say to balance tires anytime they are mounted, or repaired.

Anyone want to ride in this plane?????????? Its a China airline that flew into Frankfurt Germany and they grounded it, the germans are a bit fussy over their workmanship. the weights are seat belts to balance a vibrating engine, attached to the engine why not they even have straps attached to tie them on. Just think, in a short while according to the local newspaper they will be shipping cars over here_cid_001301c7454c_2c3c7860_0201a8c0_RCA.gif

Balance the running gear. That means - tire, wheel, brake drum.
Most of the newer airstreams have larger brake drums so it is more important to them, but the cast iron brake drums are not balanced.
A couple of of the airstream members did not believe it so while changing their tires they checked the drums too. The worst drum was 5 ounces out of balance, most were about 2 ounces out.
So the axle factory sends axles out, and the drums are round, but they don't balance. Until the customer complains why change it?

Looks like a lot of FOD damage on the fan. I doubt that the Germans grounded it. The vibration was probably so bad, that ithe engine was out of the operating limits so it had to be removed. Could have happened on landing due to thrust reverser operation.
