what tires have good traction on grass?

hi so i want to practice wheelies on grass, since it's much softer to crash on than asphalt. i dont think the street tires on my X will have any grip. what are other options? thanks.

None. No tires that I've ever been on have truly good grip on grass.

I've ridden my X tires on grass. You just need to be easier on the corners and in deceleration.

A full knobby will help but grass, especially dry loose grass or wet grass, will always be kind of slippery.

Ditto

throw some studs through some knobbies.
