Hockey pucks are much cheaper. That's what I used and unless you were looking for them, you'd probably never notice them. For my third brake light, I cut a few pieces of PVC and used longer bolts to raise it up over the tire.
+1 on the hockey pucks. I himmed and hawed for a few months checking out everything from heavy duty brackets to swing out tire carriers. Finally said the hell with it and bought a bag of hockey pucks, stacked them x2 for each bumper and the factory tire mount hasn't made a sound. Trimmed the edges to follow the edge of the rubber bumpers and you really can't tell they used to be hockey pucks.
What do you think of the Rugged Ridge Tire Carrier Spacer?
I would avoid it. The reason being is that the spacer adds to the leverage the spare tire has against the tailgate and OE bracket which is not good. The OE bracket is barely up to a 33x12.50 spare as it is, adding a spacer onto it so a bigger heavier tire can be mounted without additional support can just cause problems. My OE bracket cracked and failed within months of mounting a 33x12.50 spare tire on a light aluminum wheel.

Here you go.... They have been on only a few months but I haven't had a squeek, rattle, nothing.
Holy cow. I though mine had a little backspacing. I only needed one per for my 3-5/16 MT wheels. I never trimmed mine. I just left them round except for the ones I needed to cut to fit (bottom and top right by the hinge).
