Real good tire I have them on my smt-10 mud truck and they hold up real well with the weight , tires don’t tend to roll under like the softer mud slinger xl that I tried first. I also crawl with it and they grip good on all surfaces. Highly recommend and the price is right.

These are truly nice tires. They are so realistic looking like real big truck tires. Full rubber, no plastic look, big gnarly treads side treads, and paired with Mickey Thompson 2.2 steel wheels, they offered quite a lift on my Toyota 1/10 scale. I'm really glad happy with a combo between the Mickey Thompson wheel and The Rock Crusher tires. These Rock Crusher tires are quite firm and yet soft if that makes sense. My truck weighs just under 8 pounds tipping the scale at 8 pounds. And the foam in these tires are quite adequate they firmly hold up the truck no problems. No need for higher-end foam at least for me. So I love these tires they are totally 5 and 1/2 in tall and really give nice lift. Super happy I would buy these again absolutely. Truly impressed with RC four-wheel-drive products. And impressed with A Main Hobbies

The tires are great. They are very sticky and have a great tread pattern. I give it 3 stars because the inner foam is complete garbage. It lasted about 4 hours of trailing before it completely broke down and left huge flat spots in the tires. If you get these go ahead and change out the foams before they ever go on your truck and you will have no problems.

Great tire bolt on my hot racing rims I got from this website. Soft compound word great for crawlers.

I have three sets, my go to tire. Great scale looks and great rock and trail performance. I do like my tires very soft. If you like them a little firmer for side hilling etc you may want to run dual stage foams. These are only 5.5 inches tall - nothing very XT about them.

What reviewers say

Reviewers generally rate these 2.2-inch crawler tires highly, praising their grip on rocks and trails, realistic scale appearance, and good value. Owners running them on SMT-10 and Toyota 1/10 scale trucks with Mickey Thompson and Hot Racing rims report they hold up under vehicle weight and do not roll under like softer alternatives. Opinions differ on foam firmness: one reviewer found the included foam sufficient, while others prefer softer setups or suggest dual-stage foams for side-hilling. The main recurring complaint is that the stock inner foam broke down quickly for one reviewer, who recommends replacing it before installation. One reviewer also noted the tire height is about 5.5 inches, which they felt was short for an XT-style tire.

  • + Strong grip on rocks and trails
  • + Realistic scale look
  • + Holds up under vehicle weight
  • + Good value for price
  • − Stock inner foam can break down quickly
  • − Height about 5.5 inches, shorter than XT-style expectations
  • − Firmness may need dual-stage foam for some setups
