Best aftermarket tires for Traxxas Slash 4X4 — mostly road, some grass?

For a Slash 4X4 that runs mostly on pavement with occasional grass, choose a short-course tire with a shallow, street-oriented tread and a firm rubber compound. There isn’t one tire that will grip well on both: a pavement-focused tire wears less on road but will have limited bite in grass.

The tire guide identifies JConcepts’ firm Yellow/A1 compound for abrasive surfaces such as asphalt, while grass needs more tread than a smooth or shallow-tread road tire.

• Check that the tires fit the Slash’s short-course wheels, typically the 2.2/3.0 SCT bead size.
• If grass grip matters more than tire life on pavement, use a more open, lugged tread instead.
• If you regularly switch between the two, a separate wheel-and-tire set for grass is the better compromise.

Expect a road-focused tire to spin or slide more on grass, especially when it is wet. The available tire information doesn’t confirm a specific aftermarket tire as best for this exact mixed surface use.
