The '03 Dodge truck is the first year of the 3rd gen Dodge with 17" wheels.....16" wheel would no longer fit over larger brakes on 3rd gen and up Dodge/Ram trucks.
Mines a 97 so it should fit 16" rims, but its really not necessary, as long as outside tire diameters are acceptable and 1/10th inch difference between the 16" and 17" tires is close enough to use as a spare, even for longer distances and high speeds.

And of course a trailer wheel is lug centered vs a automotive wheel on our Dodge trucks are hub centered.
Id have to respectfully disagree and say dodge mounting is both hub centric and lug centric, but you could use it with only the lugs since they are cone shape and center the wheel. But the pilot hole on both the dodge and trailer rim is 4.75". I think hub centric rims use flanged lug nuts?

Trailer wheels are notorious for the tire seat flange not concentric to the lugs. This can create a balance nitemare on a truck with hub centered system.
You would have to make sure the tire tech checks each trailer wheel for lateral and radial runout. Most tire techs don't.
I can continue to run my dodge 17" rims on the truck, but I'm happy to have figured out I can use a trailer rim as a spare since the outside diameter is close. But I will keep in mind that trailer rims arent held to the same standards as truck rims..
I'm considering narrow LT235/85R16 Michelin Defender LTX M/S tires on 16x7 8x6.5 trailer rims
