In my words
I keep BFG T/A KM3 1.9 Predator Rock Tires 2 F/R on the Rock Crawler shelf because grip is the only variable I can still change at the track.
The set runs 1.9" across, fitted front and rear. 1.9" this spec sits in the middle of the range, so it is the set I would buy first and judge the rest against.
Sizes and colors come and go on this one; the listing shows what is actually in the box today.
What Pro-Line says about it
- Perfect size at 4.75” tall x 1.77” wide
- Deep, Self-cleaning Independent Tread Blocks
- Aggressive Tread Lugs that Bite onto Loose or Muddy Surfaces
- Flex Zones Provide Maximum Grip to Get Over Obstacles
- Made in the USA
Questions I get about this set
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.
Which insert goes in?
Inserts are not included with this listing, so budget for a set. A closed-cell insert holds shape under load; an open-cell one lets the carcass work. Heavy cars and high-bite tracks want the firmer option.
