The Traxxas TRX-4 is a 1/10 scale RC rock crawler, and its aftermarket tire scene runs on 1.9″ scale tires from a small group of specialist RC brands — this is not a full-size vehicle, so every product here is a scale RC tire, not an automotive one. These eight are the tires the RC crawling community most consistently names as favorites for the TRX-4.

- Predator compound

- Same trusted Predator compound as the Hyrax

Pro-Line Krawler 1.9″

RC4WD’s newer X2S3 rubber compound, described by RC crawling communities as close in feel and grip to Pit Bull’s premium Alien compound — a real alternative to the Pro-Line Predator ecosystem.

- 1.9″ scale, licensed Milestar Patagonia M/T tread
- Available in RC4WD’s X2S3 compound
- Distinct licensed tread pattern from the more common Interco/BFGoodrich options

Buying tips
- The TRX-4 is a 1/10 scale RC crawler — every tire here is a 1.9″ scale RC tire, not a full-size automotive tire, so don’t cross-shop these against real vehicle tire listings.
- Tire compound (usually labeled Predator or a proprietary blend like RC4WD’s X2S3) affects grip and wear as much as tread pattern — a softer compound in an aggressive tread like the Hyrax gives maximum rock grip but wears faster than a harder compound.
- Taller tires (4.75″/XL sizing like the Interco TSL SX XL or Goodyear Wrangler MT/R 4.75″) add ground clearance and a taller stance but also add unsprung weight, which can slow steering response on technical courses.
