So i am about to go buy some new tires for my 5th wheel, and tire shop is saying dont bother pay to have them balanced , its not necessary.What does everybody do here? They are for 29ft 5th wheel 225-75-15

Balancing is good. They will also tell you no need to rotate, but I do that too. If you search the forum, you'll find out why it's a good idea.

Well it was like 6 or 7 years ago and i pretty sure i balanced mine too, trailers out at the storage yard at the moment.

Get them balanced, why wouldn't they need it?article

I balance mine, just be aware that many, (most?) trailer tires are lug centric and not hub-centric. So they will have to be able to balance them with the lugs and not the hub. Many car tire places don't have the adaptor to do that.

Tires jumping up and down on a trailer is the result of severe flat spots from locking brakes......tread delam issues/etc and no amount of weights would ever balance the tire.

Sound like a experienced tire dealer that has been around the trailering world to me.

If a tire is properly dynamic balanced there may be weights on both the inside and outside.

Often the weights on the inside will not be in the same location as the outside. That is how the dynamic balance is achieved.

I know Discount balances that way; both inside and outside weights and not necessarily in the same location, as you say.

Find another dealer, if they're giving you such cr@ppy advice. Anything that rotates at that kind of speed needs to be balanced. I've seen more than a few trailers going down the road with wheels bouncing off the ground. The worst was a TT that had the left rear tire bouncing, I kid you not, at least 4" off the ground. I have no clue as to why the driver couldn't feel that. On top of that, he was towing at about 70-75 mph.

The 5.5 oz. mentioned was needed at the normal location on the wheel. I presented this to show the fallacy of dumping a substance in a tire in the hopes of getting perfect balance. Since nobody checks the drum balance and has no clue where the heavy spot on the tire or drum is located, they have no idea of the amount required.

I static balance the assemblies or use my strobe on the vehicle to get them right.

Not a believer in those, they need to reorient themselves every time the speed drops to a certain point. I asked the believers this question a long time ago: How many ounces of beads would you add to a tire that is 4 ounces out of balance with a brake drum that is 5.5 ounces out? Never got an answer. This is a real situation that I experienced. I knew the heavy spots on both and mounted with them opposed, so only 1.5 ounces of weight were required. For the bead fans, please calculate the amount needed (hint: it would be between 2 and 14 ounces).

The only downside I have witnessed with beads on one vehicle was a F450 that would shudder at low speeds when the beads were not distributed around the tire...(front tires) It happened briefly when speeding up, and slowing down.
The owner took the beads out and used normal balancing to fix it

An out of balanced tire would effect the wheel bearings.

Hmmm.. I balance my 16" tires. Seems to me to be simple common sense..NO.?

But it also seems to me that tires will rot before they wear out on most RV's...

Cheers...

"Some" motorcyclists use them, not "many". Definitely in the minority. They seem to do no harm at low speed, but I've heard of issues at higher speeds. I balance my wheels the old fashioned way. I figure since there's no way to check the balance of a tire with the beads, you're just taking their word that they work.

Caveat emptor.

Lynnmor, They are pretty popular in the trucking industry, and also many motorcyclist use them. I’m experimenting with them on a couple of trailers and on our Ram tow vehicle (19.5” tires/steel rims). So far so good,very smooth ride also.....though they don’t “soften the shock”, when those 14 ply tires hit a pothole! :D memtb
