Specifically designed with the highest crawling performance in mind the Rocx is a winner right out of the package.  JConcepts has pulled out all the stops to ensure a competitive product.  Starting from the Soft Sticky Green compound, detailed tread, tire over insert packaging all the way down to the "Peachy-1" medium density memory inserts, JConcepts is striving to set a new standard.
 
Please make note that the Rocx tire is a directional tread pattern and the first crawling tire designed with specific left and right marked indications.  Please mount the Rocx tires accordingly.
 
Although JConcepts crawling representatives report that running the Rocx tires as indicated produce the best balance of grip in most conditions, it is highly recommended that everyone experiment with personal testing to see what works best in each individual location.

For example, the Rocx tires include detailed inner carcass ribbing which improve sidewall support.  JConcepts representatives have experimented by removing the inner ribbing with curved scissors.  This has shown to improve performance in vertical climbs and in conditions where more sidewall flex is desired. When in doubt, try it yourself.

JConcepts reps have also suggested a break-in procedure so that the tires work their absolute best immediately on the rocks. Find a suitable area of concrete or asphalt and perform figure 8s using the throttle aggressively for an entire battery pack. This will start to wear the leading edge of the lugs and the carcass so that the initial "smooth" surface is worn in.

Our reps have also mentioned that experimentation with the inserts may be necessary depending on weather conditions and surface. The Peachy-1 inserts are designed to be an all around option, but you may find something that is better suited to a particular location or climate.

Rocx tire flexing its muscles -   

JConcepts representative Donnie Jackson has been involved in R/C for 20+ years and has since taken to competitive crawling.  Donny states – “The Rocx tires have everything that I have been looking for.  I have tested all the latest fashions and “trendy” options and the Rocx are my choice for serious competition.  The Rocx are just so adjustable with the inner ribbing and directional tread pattern they are capable of just about anything. I have these mounted and ready for first outing at every competition”.

Matthew Tiller a rock crawling national competitor and JConcepts representative had this to say about the Rocx tires. “Like everyone I have tried just about everything on my rig and after attending the JConcepts Bash and using the Rocx tires on the multi-surface course the Rocx tires made a believer out of me.  The large diameter and directional tread combined with the JConcepts rubber took my rig in and out of trouble spots like never before”. 
 
The Rocx tires have several key standout features which include:

• Proprietary Soft Sticky Green rubber crawling compound
• Peachy-1 medium density memory inserts
• Detailed and scaled lugs with directional tread (an R/C industry crawling innovation)
• Large overall tire diameter
• Inner sidewall ribbing support
