after doing the math i figured they would fit without rubbing,,,4wheelparts told me they would not....so I ordered them anyway 275/60/20 basically a 33/11/20 i also ordered the tucked in procomp wheels 6.25 backspace, 32mm offset 20x9. they said were too tucked for that large tire on my truck wrong again....i have a 2" level kit just on front and they all fit perfect not even a small scrub when bottomed out.
also the wheels are 65% off on 4wheelparts they were$1400 for 4 wheels I got em for a little over $500
maybe this will help with someones decision making.
Thats awesome, I got the same deal about a month ago on 4 wheel parts website too. They did the same thing to me as well as far as telling me what would and wouldn't fit on my truck. They said don't go bigger than a 285 tire. Well i went with 20X8.5 procomp wheels and some 305/55/20 tires which equated to something a little bit bigger than a 33" tire. I also have the leveling kit.



It just goes to show, you aint gonna know for sure until you put them on the truck!

Keep in mind that your trucks still new and the suspension isnt worn and sagging yet, someone with a few more miles on their truck may not be able to get this combo to fit without some rubbing and/or additional lifting.
4Wheel Parts bases their fit criteria on specs from the factory along with actual fit tests done at their testing facility on customers vehicles that usually have some miles and wear and tear on them.
If you watch the want ads in the Ranch Cucamona, Ca. area and you'll see requests for a certain type vehicle that they're offering a good deal on parts for, this is done when they have a new part that they want tested for fitment and or durability.
For anyone interested in this type program most parts manufacturers offer this to the general public, it's usually first come first serve and the vehicle must be in good repair and driving order. theres a lot of rules involved with these programs and your required to pay for transportation of you vehicle to and from the test fit site. But you usually get new parts installed for free on your vehicle.

Sweet looking wheels and tires. I would like to level and slap 33's under my rig too.
