Upgrade your tires.
The VEX 4" High Traction Tires are replacements for the "all-purpose" treads found on VEX 4" diameter wheels. These tires are designed to provide high traction on smooth surfaces. Use with 4" VEX Wheels
*Note: Wheel rims not included. Simply remove the current 4" tires from their plastic rims and replace them with these high traction ones.
