J Concepts 1/10 Dotek 2.2” Rear Drag Racing Tires and Inserts, Green Compound (2)

Features

Overview

A lot of chatter in the RC community brought the JConcepts team to producing a new tire in a much wider configuration with a treaded carcass. Dotek by JConcepts is the latest wide-body, treaded tire built specifically for RC Drag Racing and Bashing. At the heart of this design is the 2.2 x 3.0” configuration but stretched out to create a larger contact patch. Forward traction is the name of the game and the goal of the larger area, in theory, gives a racer a slight advantage in the “hook and go” department.

Adding the Dotek tread pattern added a touch of versatility to the design for dusty areas, concrete sessions, and conceptually more bashing requirements. The directional nature, marked by L and R on the tire feature low-profile padded and intentionally carved areas to provide additional hang-up to lock into un-prepped areas where dirt and debris are found. Radial security on the center of the tire provides additional “beef” to the design to give low RPM burnouts more rubber to go the distance.

One of the tricky aspects to drag racing rear tires is tire expansion and controlling this aspect of power and acceleration. The JConcepts design team thickened the entire carcass, added new inner sidewall ribbing on the inside and outside and then an industry first waffle inner weight reduction pattern. The waffle pattern accomplishes 2 things, weight reduction and provides some resistance to expansion to split some difference between a heavily restricted belted tire and a tire with no inner structure.

Dialing in the tire is a racers job but starting with a great base setup is key and the Dotek have all the elements of a successful design. Another exciting feature designed into the sidewall is the ability to add a beadlock style wheel such as the new Starfish wide beadlock wheel (#3415B). The rear tire has an inspired look with a wide-body footprint so the driver can feel the straight-line forward stability with very light rolling resistance. The 2.2 x 3.0" size makes it traditional in feel but because of its width, fits a new line of Mambos sized wheels such as the (#3408B, 3409B and beadlock 3415B).

The rear tire is designed as a low-profile shape to fit inside close quarters of a vehicle and body shell while maintaining the crisp response of a race tire. Dotek have raised lettering which can be detailed for shows or displays or simply left without for a sleepy yet devastating look. A new feature included on the sidewall is a L and R designation which can be colored to indicate direction. The JConcepts tires include the carcass forming closed-cell, black in color Dirt-Tech inserts known for their durability, performance, and consistency.

Notes from the team

The Dotek tires are rated for a maximum of Street Eliminator 2S power only. They are not guaranteed against any running damage from extreme power situations from anything above and beyond the rating. The tires are not belted, only reinforced with internal rubber ribbing.

Green compound = super soft feel, high expansion rate and recommended for cooler weather conditions while the gold compound performs in mild to warm temperatures and excels on treated surfaces. Ideally, the surface temperature range should be 80 degrees or below for green compound and above 80 for gold.
