Description

The JConcepts Magma pre-mounted large-scale tyres combine speed, durability and grip for demanding RC bashing and high-speed runs. Mounted on multi-piece Hazard wheels (#3425) with inner and outer beadlock rings, this complete assembly is built to handle extreme use while delivering confident forward bite from its distinctive horizontal, bridge-shaped tread.

Engineered on a rugged carcass with heavy inner x-bracing, sidewall support ribs and blocking, the Magma design helps minimise expansion at speed. A tall, long-wearing tread profile with horizontal cuts, diagonal reliefs and outer receptors boosts traction and steering support across a wide range of dirt and bashing surfaces. Open-cell inserts are pre-installed for dependable, versatile feel, while bold tyre lettering completes the authentic JConcepts look.

The pre-mounted set includes hardware and hex adaptor options for vehicle versatility. The installed option with a 17mm hex is indicated for popular models such as the X-Maxx and XRT, while the optional adaptor is noted for the Arrma Kraton 8S. Two different 24mm hex adaptors are also referenced for additional versatility.

Specifications

The Magma tire by JConcepts is an all-around performer for large scale RC drivers looking to conquer the toughest terrain while driving at incredibility high-speeds. Available as a pre-mounted option on Hazard wheels, the tire is designed with extreme abuse and speed in-mind, the Magma tire has giant horizontal tread which is bridge shaped and constructed for massive forward-bite. The tire and wheel are designed to complement each other as a complete assembled unit.

The tire carcass is built on a large and rugged carcass where the beads provide hole locations to lock the position with the Hazard wheels. The tires have heavy inner x-bracing, sidewall support ribs and blocking to help minimize expansion. The stance makes high-speed runs and turns possible and the race enhanced compound grips to just about any bashing or dirt surface imaginable. The tall tread provides a lot of life in multiple conditions and the detail in the tread with horizontal cuts, diagonal reliefs and outer receptors help the side-wall of the tire. Bold tire lettering on the outside of the tire gives a high-impact look and authenticity exclusive to JConcepts.

The pre-mounted Magma tire is mounted with open cell inserts for versatility and dependability. The multi-piece Hazard wheel is secured to the tire with dependable hardware via beadlock rings on the inside and out. The pre-installed hardware fits together tightly and bites through the tire bead to hold the hefty assembly in position. Two hex adaptors are included to accommodate different vehicles on the market. The installed option with 17mm hex installs directly to the popular vehicles such as the X-Maxx and XRT. The optional hex will need to be placed to fit on the Arrma Kraton 8s.
