ROAR: Rule Change for 10th scale buggy wheel construction

2 posts in this topic

May 14, 2015

ROAR is introducing a rules change with immediate effect that results in 2 different wheel configurations being available as options for manufacturers and competitors:

- the existing 2.2" nominal wheels

- the newer 2.4" or 61mm nominal wheels

The new rules do not include dimensions compatible with vintage style wheels as they are generally not used in ROAR sanctioned competition.

Dimensions for the traditional 2.2" wheel will be:

- Mounting Bead Diameter - 2.20 inch (55.88mm) +/-.013 inch (.30mm)

- Maximum Overall Diameter - 2.42 inch (61.468 mm)

- Width - 1.513 inch (38.43mm) maximum

Dimensions for the newer wheel style will be:

- Mounting Bead Diameter - 2.380 - 2.427 inch (60.45 - 61.65 mm)

- Maximum Overall Diameter - 2.571 inch (65.3 mm)

- Width - 1.513 inch (38.43mm) maximum

JConcepts – Reflex – 60mm 1/10th Buggy Tires

Reflex_Group.jpg

The Reflex tire is designed to bridge a gap between the popular Double Dees and other options such as 3Ds and Hybrids. The Reflex has square, angled pins that are stacked vertically to flex and fold evenly across the tire. Typically a stacked tread will wear less and provide more forward bite while the aligned space helps rotation in the turns and gives a snappy release to square up quickly.

Starting with the new tread, the team focused on durability and performance to bring a rear tire option to market that competes on loose surfaces which are wet or dusty. With the popularity of mid-motor buggies and the focus on steering and corner speed, the Reflex releases and bites hard during corner exit for straight line acceleration. The blended tread to tire body is supported with a generous radius which promotes “pin snap” and also resists tearing or separation.

Horizontal traction bars connect several pins near the center of the tire which bonds a critical area for increased push at high-speed. The sidewall area blends nicely into a step-spike feature which helps smooth the transition in bumpy sections and also create side-bite. The Reflex are built on the 60mm bead and carcass design making them interchangeable with all 60mm | 2.4” wheel combinations. The interior ribbing features the double-hatch pattern that helps maintain a comfy ride while each set of tires includes the Dirt-Tech closed cell inserts.

Features:

· JConcepts original tread, available in multiple compounds

· Square, angled pins with horizontal traction bars

· 60mm | 2.4” bead mounting size

· Carefully shaped carcass = smooth driving characteristics

· Includes Dirt-Tech closed cell inserts
