Default Dual Axle trailer - sharp turns - possible to damage wheels, bearings, etc?

During a sharp turn today I noticed that the back tires were leaving quite a bit of rubber on the ground and weren't really turning but grinding across the pavement. This seems pretty bad, but since I just re-packed my bearings I'm wondering if it is possible to do damage to the bearings, especially the rear seal during a sharp turn. Thoughts?

I have noticed this myself especially when backing. It made me cringe how the tires looked like they were going to pop off the rim. Nothing ever happened so I don't think it hurts anything. I wonder what everyone else thinks.

I've got a triple axle and in tight turns at least one and sometimes two wheels just grind. It does not appear to be harmful so I don't give it much thought.

With a twin axle, the sharper the turn and the greater the load, the more tire scrub you will get. You get even more tire scrub with a tri axle. Just compare pushing these trailers around a corner . . . the more axels the harder the job.

Tires squirm and you get scallopped wear on the sides of the tires if they are under-inflated. Trailer tires have stiffer sidewalls to reduce the tire squirm.

I do not know what the impact is on bearings or if they wear out sooner. I disassemble and check mine once a year.

Hope this helps.

Sailor, this is perfectly normal.. May not seem so, but with both wheels locked in line with each other, there's only one thing for them to do and that is one axle will follow the other one. This results in the tire being slid laterally.. This is really where most of the wear and tear occur on a tandem or triple axle.

Watch big rigs and the rear trailer axles (the two axles) while in a turn, you will see the rear ones doing the exact same thing.

No worries, just rotate every year or two depending on how many miles you travel...

Later,
Chris

I know that it may not look right but it is a perfectly natural occurance; big trucks have been doing it forever.

As for the bearing concerns, I wouldn't worry for a moment. The wheels rate of rotation is so slow..........

Thanks.....I realize the effect of the wheel slipping is completly normal during a turn, but what I'm most concerned about is that during this time it looks as if the wheel suddenly has more camber and which I know is putting stress on the axle and bearings. I'm wondering if this is a reason for blown inner seals.

As others have surmised, what you observed, while unavoidably normal, is stressful to the trailer. If you stop mid turn and note what was actually deflecting, you will discover several things deflecting. Spindles, bearings, seals, are the stiffest system of parts in the suspension system and I observe them to stay together as a set, so the inner seals should not experience displacement stress. Deflection occurs mostly in the tires, secondly in the axle itself( or torsion arm), and thirdly the wheel rims.

I don't know what type of trailer/axle setup you have. But usually the rear seal is part of the axle housing or the backing plate. And in either case most definetly would not be affected by the tire scrubbing in a tight radius turn.

If you're blowing out rear seals regularly two things comes to mind.

One.....You're running bearing buddies and pumping to much grease in.

Two.....The axle has a slight deflection, a nick/spur or maybe a rusty spot.

I hate to look at my tires when I make sharp turns. It just can't be good. I also hear some noises that don't sound great so now I don't listen either!

Some damn trucker turned his rig around in my company's employee parking lot the other evening. I know because his dual axle trailer tires dragging sideways in the tight turn plowed up the dang asphalt into a 6" tall berm. I bet that sounded nasty.
