Shawn LeskoVerified owneron JConcepts Arrma® Mojave Grom™ Smoothie 2 Pre-Mounted Tires (2) (G3 - Soft)

Bought these for running on my brushed cement driveway. Installed on a Mojave Grom converted to 3s brushless with a Hobbywing fusion mini16. The wheel/tire combo look great. Awesome foam inserts. Great traction. Just enough slip to prevent constant traction rolls. Can’t comment on tire life yet. So far, I’d buy them again.
