I run Carlisle Radial Trail HD tires and a friend runs Good Year Endurance tires. Both great tires IMHO. However I notice my trailer glides down the road and softer on bumps etc. My buddies trailer rides harsher and really slams or jumps on bumps. It basically really bounces the boat more.
Is this because of the much stiffer sidewalls? I prefer the softer ride as I think my boat takes on less stress. Of course maybe all the extra bounce is harmless too.
