From Gravity RC:
With great success we have been providing PERMAGRIP tires to some of our team members, so why not make it available to everyone. What makes these tires special is the 8 hour PERMAGRIP process which impregnates these genuine Pro-Line REACTION S3 tires increasing performance on all surfaces. The process enhances the rubber and simultaneously softens the inner belting. This results in more overall grip and a more desirable contact patch. With this process it is recommended to use the included insert.
#PERMA10170-203 – $44.99
