Monza Imports sent us the following information on Dunlop’s new Geomax MX32 and MX52 tyres:

Using input from top AMA Pro Supercross and Motocross racers throughout the 2011, 2012 and 2013 racing seasons, Dunlop has developed the all-new Geomax MX32 and MX52 motocross tyres. These new Geomax models began life as top Pro tyres and have now been developed into tyres Dunlop can offer to the racing and riding public.

The MX32 covers soft-to-intermediate terrain while the MX52 excels in intermediate-to-hard terrain conditions. These two tyres replace the MX31, MX51 and MX71 in Dunlop’s Geomax lineup, yet they cover a significantly greater range of terrain types than the three tires covered before thanks to revolutionary new technology.

The advantages of the MX32 and MX52 were proven in the demanding environment of AMA Pro competition. In 2013, prototypes of the production MX32 and MX52 front and rear tires were used an astounding 62 times by the overall race winners in AMA Pro Supercross and Motocross events.

These race winners include 2013 champions Ryan Villopoto, Wil Hahn, Eli Tomac, Ken Roczen and Jessica Patterson, plus many more riders. Extend that count to the top-three race finishers and the MX32 and MX52 amassed 187 podium appearances in AMA Pro Supercross and Motocross competition in 2013, while also notching holeshots with 55 fitments throughout the year—truly amazing results for tyres now available to the public.

Dunlop Geomax MX32 and MX52 tyre key features:
– Derived from top-level AMA Supercross and Motocross racing.
– New tread-block-within-a-block knobs offer more progressive cornering action.
– Enhanced handling and knob durability via more flex, and less knob tearing through recess-carcass design.
– Superior bump absorption through new damping-control sidewall rubber compound and recess-carcass design.
– Directional front tire design provides enhanced grip and steering feel.
– Superior grip in a wider variety of terrain.

Progressive Cornering Block technology:
In both the MX32 and MX52 rear tyres, Progressive Cornering Block (PCB) incorporates a new block-within-a-block configuration on the two flanks of the tyre – a design proven to deliver more progressive cornering action and aid in slide control. The key to this new knob design/technology focuses on adding overall height to each knob at the center of this new multi-block configuration—specifically, with a taller, smaller, inner knob. The additional biting edges and the increased surface area they provide effectively increase the tire’s footprint and its ability to spread driving loads more evenly across the knob for additional traction.

With block-within-a-block design, each knob damps out a portion of the force characteristics put into the tire while riding over rough terrain. The floating traits of the knobs improve stability because more of these forces are being damped out within the tyre and less of these forces are transferred to the suspension and chassis. Also, when running the bike at different lean angles, the variable height of the multi-block knobs spreads the load more evenly over the surface of the knob block, especially at the edges, to produce added bite. The block-within-a-block configuration also helps improve slide control.

Tyre-specific block pattern:
The MX52 rear tire features rows of center blocks with a slight stagger. This offset spreads the load on the tyre and helps with impact damping and stability, especially in whoops and hard-pack conditions. Now, the tread pattern has the ability to flex for compliance over various surfaces, which allows the tire to deal more effectively within a wider range of terrain. To excel in soft-terrain application, the MX32 rear features a multiple-block distribution pattern, wherein the pitches and angles of the tire blocks are varied to promote traction, while using fewer blocks, which also improves contact feel, while still maintaining excellent traction. Because the MX32 is intended for use in soft-to-intermediate terrain, the tie bars Dunlop incorporates on other tires have been eliminated to reduce bending resistance within the tire blocks to improve contact feel and promote stability.

Front tyre design:
The front MX32 and MX52 feature new directional tread patterns in both fronts that incorporate a series of unique block designs for optimal performance. The main objective is to provide great traction along with optimal steering feel for a wide range of riders who have differing riding styles. A directional front tyre can accomplish this by focusing on a more idealised knob pattern, knob distribution, knob construction and knob shape—a total package that produces heightened feel for the rider. With optimised block distribution, new block designs and carcass innovations, the all-new Geomax MX32 and MX52 offer weekend riders the kind of performance top AMA Pros used to win races and championships in 2013. Riding on the MX32 and MX52 is like having a factory advantage in your corner.
