In my words
Of everything on the Monster Truck shelf, 8x32 to 17mm Hex Adapters for 8x32 3.8 Wheels is the set I hand to people who are tired of guessing at compounds.
The set runs 3.8" across and the wheels take a 17mm hex. A carcass this size wants the right insert far more than it wants a different compound.
I do not hold inventory — the button sends you to the listing, and it carries the current price.
What Pro-Line says about it

- Made from High-strength, Durable DuPont Nylon Material
- Replacement 8x32 to 17mm Hex Zero and 1/2" Offset Adapters
- Built to Take a Beating
Questions I get about this set
Will these fit my hex?
Check the hex callout before anything else. This one is listed at 17mm. A tire that fits the rim will still rub if the offset is wrong, so measure your current wheel face-to-hub before you buy.
Do I need to glue these?
These are tires and wheels separately, so yes — bead glue is part of the job. Pro-Line tires want thin CA worked around the bead in quarters, not one bead of glue chased around the rim in a single pass.
