The GPM TMX1889PW tyre set is produced for direct fitment on the Traxxas 1/10 T-Maxx Monster Truck and uses a radial construction combined with foam inserts to stabilise the tyre shape under lateral and braking loads. The foam core supports the tread and sidewalls to reduce irregular deformation, helping to keep a consistent contact patch during cornering. For best results mount and balance each tyre on standard T-Maxx rims and check seating before running.
