currently running stock 2 ply, anyone played with a 6 ply mud light? i need to smooth it out some

Pretty much everyone here runs 6 ply I think. That's what I run.

Wouldn't the 6 ply ha stiffer wall and give you a stiffer ride?

On the FL250 I would focus more on the tread design. These are the tires I have on my FL250 and when I ride on hard surface I can feel the rough bouncy ride for sure, but they do great in the dirt and sand. I would think a knobby tread like OEM would be the smoothest.
