here's thew bottom line, since i've spent literally days looking at wheels.
a few fact..
The factory wheel i think is a 20" with a +34 offset with 8.5 wide rims
backspacing is the distance from the inner face of the hub to the inside rim.
tires rub with wheels that have a high NEGATIVE offset because the front wheel essentially swings a wider circle and will hit the back of the bumper or the splash guard.
the factory backspacing is 6.25" and when i shop wheels and because i am looking to keep them close to the truck like stock so they don't rub and don't stick out. i don't bother looking at offset rather i look at backspacing.
i can save you a lot of time and tell you if your going for this look stick with FUEL wheels. they are the only brand that offers high positive offsets and high backspacing.I
I want 22's because 20's are way to common and i am looking for an ON ROAD not off road look for my truck.
I also want exposed lugs not crappy plastic wheel caps. and the bolt pattern is 8x180mm so that limits me to about 4 choices.
currently for me i have settled on the newly announced FUEL rebel 8 because it has exposed lugs, comes in 22 and +13mm offset on a 10" wide wheel comes out to about 6.02" backspace it's 10 inches wide so it should only stick out just over 1.5" from stock.
also if your looking for 22" tires i am getting NITTO terra grappler g2 in 285/55/22 as they are the exact same diameter as stock (maybe within 1/8th of an inch) which will keep the speedo accurate and least chance of rubbing on stock suspension.
in this size and load range E (pay close attention to this if you TOW) there are only 3 tires on the market in this fitment.
keep in mind there are about 22.5 mm in an inch so if you get a 0 offset wheel from the +13 i picked that's about half an inch FARTHER from the truck.
you'll see from their website at this link they do not have 22x10x+13 listed yet as they are pre-ordered still for a few more months. But of the sizes listed pay special attention to the BACKSPACING several of these wheels list a 4.75" backspace. with the factory being 6.25" this means even if you had an 8.5" wide wheel it will stick out 1.5 inches farther than stock, if you go with a 10" wide wheel now your a full 3 inches poke out from the factory outer edge of the wheel than stock.
you put a larger tire on that combo and you have a recipe for rubbing and you definitely need a lift and or heavy modification to clearance from rubbing.
If your looking for a 20" there are a LOT more choices such as the BLITZ as pictured above from the other poster. looking at his fitment he has probably a + offset wheel in 20" and there are tons of tires in that size. i like the blitz wheel but dislike the chunky tires, poor MPG, reduced performance, inaccurate speedometer readings and unless you chose offset carefully potential rubbing issues.
I have a daily driver, this truck sits in the garage unless i am towing my trailer to go camping, dirt-biking, 4 wheelering, boating or need a snow vehicle in which case the factory wheels go back on for winter duty.
i also think i am going to get similar wheels for my trailer to match the truck!
