I just purchased a set of Carlisle ST tires for my 26’ Dutchmen. I have a neighbour who swears by balancing the tires. I asked for the tires to be balanced, and they didn’t do it, citing the fact that trailer tires don’t require balancing. I‘ve been pulling travel trailers off and on for 30 years. Does anybody have any real life experience in this situation. I’m tempted to get my wife to drive while I ride in the trailer just to see how bad the vibrations are ? I personally think half of my travel trailer repair problems are from vibration? Gracias…..
