All - I'm still trying to figure out the right Bilstein shock I need. According to www.4wheelparts.com, the Bilstein 5100 Adjustable Height shocks will not fit my truck. And according to a spokesperson there, they told me I need the more expensive ($115, so not bad) Bilstein strut, not shock. So now I'm pretty confused. This is the product I thought I needed. Can any of you tell me whether this will work on a 2010 F150 Crew FX4?
So I got the Bilstein height adjustables installed and cranked them to their full 2" lift. I went with Toyo's new Open Country RT's in 33x12.5x18. I love the new look...
One question on those tires: What pressure do you all recommend? I do mostly highway driving. They are at 40 psi right now.
The offset is +18. Discount Tires installed the tires and recommended 40 psi. After bouncing all over the road on a 4 hour road trip, I called Toyo directly. After giving them the exact specs on my truck, they recommended 55 psi. I ended up putting them to 50. Much much better ride now. Maybe I'll go to 55 but I didnt want to make that big of a jump right away. But going by what Discount Tires store recommends, and I do like those guys, is not smart. Tires are not a one size (pressure) fits all arrangement. The weight of the front and back of your vehicle matters a lot, as it turns out. Seems logical, not sure why those guys wouldn't be aware of this.
Just wanted to hear how the setup turned out? I'm looking at something similar and just wanted to hear primarily about whether there was any rubbing with those wide tires.
I've got a 2011 Platinum 4x4 with a 2" front daystar leveling kit and 20" Fuel Hostage wheels +1 offset. Was thinking about sticking to something in the 295/55 R20 range to have the wheels/tires stand out just a little, but didn't want them so far out as to have issues with rocks, etc... being thrown up into the paint.
There is actually some rubbing when I have the wheel completely cranked and usually only when backing out of a parking spot. Going forward I'm usually find, strangely. I have not had time to get underneath and look, but I've been told it is likely a very easy fix. A piece of plastic or something I can cut off from the wheel well with a dremel. Hoping so. Otherwise I'm very happy with the set up. The Toyo RT's look awesome. A little louder than AT's, but not too loud that they annoy me. Loud enough that it reminds me I've got some nice beefy tires on there though!

I think I can explain what may have occurred here. I work at Discount Tire. Our computer systems automatically tell us what psi to put in your tires should you upgrade to bigger tires or tires with a higher load index. This is based off of the weight capacity of your stock tires at the manufacturer suggested air pressure and then adjusted so that the new tires carry the same weight. I see from the pics that your truck is an FX4 and your new tires are Load Range E2 with a load index of 118 and a max psi of 65. When I plug that into our system (1st pic) it shows you need 50psi as Toyo informed you. However if your truck was entered in as a 2wd Lariat (2nd pic) and we plug in the same tire it shows you need only 40psi.
I would like to apologize on behalf of the store that serviced your truck. We strive to do the best job possible and insure no errors are made, but sometimes they do happen.
However, rest assured that even at 40 psi these tires will still exceed your GVWR so no damage should occur. However at 50 this will give you the same safety margin in weight capacity as your stock tires and would be best as suggested by Toyo.
Hope that clears it up for you!

Thank you for that explanation. Makes sense. I'm sure it was an uncommon oversight bc usually those guys are right on top of things. I bring all my vehicles to DT (2 personal vehicles, 1 work vehicle) and you've always done me right.
One other pickup specific question. I've been told that bc pickup trucks usually have very little payload in the rear unless hauling, that you should keep the psi lower in the rear than in the front. That true?
