Kevin EshenbaughVerified owneron RC4WD Rock Crusher 1.0" Micro Crawler Tires (2)

I purchased several sets of these for my mini z 4x4 models. Every one of them, even the ones that had never been run have now after only a couple months completely cracked and separated the tread from. The sidewall. I don’t know if it was a bad batch or what. But I have never seems rubber disintegrate on its own like these did.

These tires are soft and sticky and perform much better than the stock tires. They have a smaller OD so consider if that works for the look and ground clearance you're trying to achieve.

Even when not exposed to UV rays or water, tear and cracked all tires.

They look good, performance is average at best, and they started splitting around the sidewall within a couple of months.

What reviewers say

Four verified owners rated these micro crawler tires between 1 and 4 out of 5. Two reviewers reported that tires cracked, tore, or separated from the sidewall within a couple of months, including some that had never been run, and one wondered whether it was a bad batch. One reviewer praised the soft, sticky grip and better performance than stock tires, noting the smaller outer diameter may affect look and ground clearance. A fourth reviewer described looks as good but performance as average. Sidewall cracking is the recurring problem, and the reviews do not establish whether it is widespread.

  • + Soft, sticky grip
  • + Better performance than stock tires
  • + Good appearance
  • − Sidewall cracking or splitting
  • − Tread separating from sidewall
  • − Average performance for one reviewer
  • − Smaller outer diameter
