OTTSIX Racing 2.2 Voodoo U4 Tires They come in Silver (Extra Soft), Gold (Ultra Soft) and now in Blue (Super Traction)
Gold Compound: The ultimate U4 track and racing compound! This compound gives superb straight line and cornering traction.
Silver Compound: Great all around compound for those wanting to use their tires for either U4 racing or G6 type events.
Compound: THIS IS NOT A RACING COMPOUND! This is, however, a great
crawling compound, expect BIG traction in the rocks. This compound is
also recommended for heavier than average trucks. (to prevent damage to
your truck a certain amount of caution must be exercised when running
this compound. The traction profile of this rubber can cause "too much
traction" at times, which can put a fair amount of stress on various
parts of the truck)
We strongly recommend Crawler Innovations
Deuces Wild Standard size foams and 6Bolt wheels when using Voodoo U4's
for racing. For G6 or scale type driving, we recommend that you use
Crawler Innovations soft or medium, 5.5" Double Deuce foams.
