Question 1

Will the HOBBYSOUL 1.9 Mud Slingers fit my stock TRX-4 or SCX10 III wheels?**

Accepted Answer

Yes, these tires are designed as a direct drop-in upgrade for most 1/10 scale crawlers, including Traxxas TRX-4, Axial SCX10 III, and Redcat Gen8. The 120mm height and standard 1.9 bead diameter match factory specs. However, some TikTok users and hobbyists report that certain aftermarket beadlock rims with very tight tolerances may require a quick soak in hot water to soften the bead for installation.

Question 2

How does the soft sticky compound perform on wet rocks versus dry trails?**

Accepted Answer

Excellent question. The compound shines on wet, slimy rock surfaces—users consistently praise it as “gecko-level grip” on everything from riverbeds to mossy ledges. On dry, loose gravel or abrasive asphalt, the soft rubber wears noticeably faster, so we recommend reserving these for technical crawling rather than high-speed trail bashing. One Reddit moderator called them “the best wet rock tire under $50.”

Question 3

Are the dimensions accurate, and will I need new foams?**

Accepted Answer

The 4.72" height measures true right out of the box. The included foams are intentionally soft to maximize crawling articulation. That said, heavier rigs (especially those with brass wheel weights) often feel under-supported. Many YouTube builders recommend upgrading to dual-stage foams for stiffer sidewall support without losing grip—this is a common mod among experienced crawlers.

Question 4

What’s the return policy if these don’t fit my crawler?**

Accepted Answer

HOBBYSOUL offers a 30-day return window for unworn, unmodified tires. If you’re unsure about fitment, we suggest test-fitting one tire on a wheel before mounting all four. Bear in mind that “wheel wobble” or balancing issues due to non-OEM rims aren’t covered under defect returns, so confirm beadlock compatibility beforehand. Our customer service team can help match your rig to the right spec.

Question 5

Are these a better value than cheaper alternatives like Injora or Pro-Line?**

Accepted Answer

For pure wet-rock crawling, the HOBBYSOULs punch well above their price point—many owners report 90% of the performance of $60 Pro-Line Hyrax tires at two-thirds the cost. The main trade-off is durability: budget alternatives like Injora may last slightly longer on abrasive surfaces, but they lack the same sticky compound that makes these tires legendary on slick obstacles. If you prioritize grip over longevity, these are the smarter buy.
