First, Want to say thanks to everyone who posts on TW. This has been a great resource for real world answers. Did a ton of research here before I made the plunge.
Here are my new shoes. 285 Nittos on MB Predator chrome rims. I really didn't think I'd like the chrome, but they seem to work.
I have 5100's set to 1.75" up front and the TSB leaf spring only in back.
Here's what I experienced when installing the new 285's: Had to do a fair amount of trimming to both the inner well and fenders. Also had to remove the front mud flaps. Found that a good utility knife cut through everything easily. I got out the recp. saw, but found it was not needed.
Had a free alignment coming to me from the dealership, so today, I had them do the alignment with the new tires installed.
The Nittos came inflated at 60 psi, but rode real hard and accented the truck's vibrations, I told the tech it was vibrating pretty stong and he lowered the tire pressure to 32 psi (still not sure about that low of pressure). Anyway, the vibs aren't the strong anymore. If any of your are running 285 Nittos please let me know what tire pressure you are running.
Overall, I'm stoked. The visual difference it amazing. Here are some picts-
