the sidewalls are really stiff due to their construction and they aren't good for airing down where you need a lot of floatation.
I also drive technicals like Black Bear Pass in Co every August so airing down is a must!
Anyhow, the m55's were the most disappointing, overpriced, and left me with severe buyers remorse.
I think my question has been answered about the M 55's.
Mainer, thanks! great reports here from you and thanks for taking the time to give some great feedback!
I will be checking out those Bridgestone dualers.
I'm hard on my truck too, just put $7,500 into it last week repairing some stuff after hard use. But then, that is why I bought it. Love the truck and will drive it till it cain't anymore.
