No issues but I wouldn't go any taller with 3.55 gear's. I drive about a hundred miles daily on my work commute so I wanted a little better road tire so I went with the Nitto Terra's. My last truck had 3.73 gear's and I found the 295x70x17 Toyo MT's were a good match. I did have a programmer though and that helped out the tranny. Toyo MT's are great tires but are heavy and a little noisy on the highway for daily use. I think with the 285x75's (34") you'll be OK with 3.55's and a programmer.
* Do you have any issues with 33s and the 3.55 gears?
* I saw from an earlier thread, that you had Toyo M/Ts on an earlier truck. What is your opinion of the Toyo M/Ts? I see you went with something else on your new truck.
* I have a 2010 Screw with 3.55s. I'm looking at 285/75r17, Toyo M/Ts (34"). Having run bigger tires with 3.55 gears, what's your opinion on this combo?
