i know how low i want to run 33" TSL swampers on rocks and sand, but what is optimum in the mud? standard street pressure? i do not have beadlocks. thanks

I ran in the swamps of Florida for 15 years. During that time I never found airing down to help in the mud. Obviously it helped in the sand but I never noticed a difference in mud.

I ran mine at 25-28 on the street and they rode pretty damn good for a 8 ply bias. When I went offroad (mud/clay/rocks), I went down to 5~ or so.
