Help a Guy Decide

I have a 2006 PSD Super Cab 4X4 with 3.73 gears. I am running factory tires and rims but want to step up to a lager tire size. I have bought Mickey Thompson Classic II's (17X9) and want to wrap them with 35's. I belive that I will need at least a levelling kit to do this as the rims are going to stick out an extra 2.5" from where they sit now. Here are my questions:

1. Will 35's fit with no levelling kit?
2. With 3.73 gears will I notice a big change in power? I pull an 8,000lb travel trailer and a 1000lbs of gear in the box of the truck.

If you have a similar set up please attach some pics to your reply.

Thanks

The problem your going to have is getting those rims to fit. The 05-07 brake rotors are bigger than the previous 03-04 truck. But to answer your questions, I think your going to need the 2.5" leveling kit to use the 35's. I'm not sure how they will affect your towing abilities though. I know when I went to bigger tires on my old 150, I did notice a difference, but not much. I only went up a couple inches in height, but the width is where the extra weight came from.

Why would I have any trouble fitting the Mickey Thompson rims?? I am going from a 17X7.5 to a 17X9 with less offset. I don't see an issue with that. My main concern is loss of power going up 3 inches on tire size.

I am with the other guy. those rims may be to small. I just looked at mine and i have 18x9 4.75 backspacing and have about 1/2" of clearance between caliber and rim. I would test fit a rim on the front and make sure before going any further. I you are worried about the lose in power better just stick with want you all ready have.

I have heard from a lot of people that 17's won't fit on the newer trucks . That's all I had to go on. My rims are 18's on my 350. That's cool that I may be able to use 17's, cause the tires are cheap, and so are the rims.

I'm not sure that going to 35's on a powerstroke is going to affect the towing very much, you may not even notice the change in gearing

Post up pics when you get her finished up

I had a friend that put 35's on his truck, with the same gearing as you, and he never complained about towing his 10k 5er. His is a 6spd though, so that will make a difference

He is taking off his 17's and putting the same size back on, as long as the back spacing is correct. I was under the same impression you are about them having to be at least 18's. Maybe my wheels are bigger because I have a 350 instead of a 250

The truck has factory 17's and will be replaced with 17's. There is no problem with the rims here guys, the problem is the tire size and the gearing!!

I think that you will be fine going with the 35's. When I was running 35's I had no trouble towing!
