That Falken Tires AT3 & Most 10 Ply tires ( E Rated ) will be a little rougher on the ride. Specially those with a 3 Peak Mt Snowflake sidewall. It makes the sidewall super stiff. If you are looking for a smoother ride, look for a C or D Rated Tire. Plenty of options in the size you are looking for.
I have a set of them coming today. If/when I have an opportunity to get them mounted and have some drive time on them, I'll circle back to this thread and give a review..
I got my Wildpeaks installed yesterday morning. I have about 100 miles on them so far. Early indications are that I'm gonna love 'em. Believe it or not, they are quieter than my 33s were (275/70/18 Firestone Destination XT), and seems like a smoother ride too. Mounted on the Pro Comp wheels they weigh in at 104# each.
