Conversations other than tires related to RV use will not be tolerated in this forum.......use the PM system instead.....
I think most on here just want to know where they can get tires that are round and don`t come apart.:R
Even when they look round, there can be problems. I have heard of out of round tires. I see lots of trailers of all different sorts on my way to and from work. Most seem to run pretty smooth, however, there was one exception the other day. This was a real heavy duty tandem axle flatbed, about 16 feet, hooked onto a pintle hook. It was empty, and all four tires were constantly bouncing about 1" off of the road, even on smooth pavement. You could see every part of the trailer violently shaking. But, looking at the truck that was pulling it, I could not see any evidence of vibration being transmitted through the hitch to the truck. So I wonder if the driver was aware of the problem.
This leads me to my next question for Roger and Barry. We know how important proper balance is for tire wear, but how much heat would one expect to generate in the tires due to an imbalance like I observed the other day. I guess what this is leading to in laymen terms is: since trailer tires generally age out before they wear out -- how important is it for reliability to have them balanced. Note: for the most part, OE trailer tires are not balanced.
Second question is with regards to the ceramic balancing beads. I know some tire manufacturers will not honor their warrantee if they are used. Why? Do these beads damage the liner?
I would not think of bouncing as generating much heat. BUT given that detachments initiate when there is high load which causes higher deformation it seems logical that bouncing could generate higher than normal deflection at the point of contact which in ture would result in that part of the tire rubber "seeing" deformation as if it were being overloaded.
Since all damage is cumulative and the tearing can only grow I would think that excessive bouncing is not good for a tire.
RE beads etc in tires. Some think they are OK. If you can get a warranty in writing from the bead manufacturer that he will honor any tire warranty rejected because of the beads then it might be ok, otherwise I would get on vehicle spin balance as you need to be sure the tire, wheel and hub are all in balance but also you need to check runout as you can balance a cinder block but you would not have a good ride.
Interesting idea regarding asking the bead manufacturer to back the tire warrantee if the beads invalidate it.
