This is a pair of ultra firm foam tire inserts for MAXX Monster Truck Tires from Pro-Line. If you find the stock foams in Pro-Line MAXX tires to be too soft allowing the tires to roll over in the corners, these are a great replacement foam to use instead that is firmer than the stock foams to provide a firmer overal tire feel.
These foams will NOT fit inside 40 series or Revo tires!!
