...It came with a set of fake bead lockers that are much deeper than the stock wheels but im worried that they will rub with much steering angle.
That type of wheel is typically wider, but no generalities on offset/backspace or overall width. Just that they're usually wider than stock.
Only ways I know of to see if it's going to fit or rub is to either measure them, or actually try them on for size.
For the first, measure between the beads as was described above to get the rim width. Then place a straight-edge on the inner beads then use a tape measure from the mounting flange (around the lug holes) to the inside of the straight edge.
If the wheels are wider than 8" then you'll probably rub even the skinniest tires (which would not work on that wide of a wheel anyway). If they're 8" or less, then look to the backspace numbers you just measured. Anything less than 4" on an 8" wide wheel will likely rub with a 10.50 tire.
If the wheel is a 7" wide model, you can get away with between 3.5 and 4 inches I believe.
If the tires are particularly wide, or have an aggressive side lug design, you may have to try them on for size even with the wheel measurements in hand. Just too many variables to know for sure with all tires.
Did you guys paint your stock wheels or powder coat them?
Can't say for them, but I think most go to the trouble and expense to powder coat. Though there have been more and more lately that are having their trucks painted anyway, with many of them opting to have the painter do the wheels too while it's in the shop.
A good auto paint will work great for years. A decent rattle can job will only last a short time (maybe 1 to 2 years?) but is also easy to touch up too.
Mine are powder coated something close to Ford's Wimbledon White. They're aftermarket 7" wide steel wheels from Wheel Vintiques.
