JConcepts Mambos SCT Street Eliminator Drag Racing Rear Tires (2) (Gold)
About this part
One of the tricky aspects to drag racing rear tires is tire expansion and controlling this during acceleration. The JConcepts design team thickened the entire carcass, added unique inner sidewall ribbing on the inside and outside and then an industry first waffle inner weight reduction pattern. The waffle pattern accomplishes 2 things, weight reduction and provides some resistance to expansion to split some difference between a heavily restricted belted tire and a tire with no inner structure.
Dialing in the tire is a racers job but starting with a great base setup is key and the Mambos have all the elements of a successful design. Another exciting feature designed into the sidewall is the ability to add a beadlock style wheel such as the Starfish wide beadlock wheel (JCO3415B). The rear tire has an inspired look with a wide-body footprint so the driver can feel the straight-line forward stability with very light rolling resistance. The 2.2 x 3.0" size makes it traditional in feel but because of its width, fits JConcepts Mambos sized wheels (JCO3408B, JCO3409B and JCO3415B).
The rear tire is designed as a low-profile shape to fit inside close quarters of a vehicle and body shell while maintaining the crisp response of a race tire. Mambos have raised lettering which can be detailed for shows or displays or simply left without for a sleepy yet devastating look. A feature included on the sidewall is a double arrow which can be colored to indicate direction. The JConcepts tires include the Mambos carcass forming closed-cell, black in color Dirt-Tech inserts known for their durability, performance, and consistency.

I bought the Mambos because they are a great price on sale. I was bit skeptical once I saw them out of the bag with a big seem in the middle of the tire. If you're a serious racer you'd definitely want to sand these before running. I threw these on my 13.5 car with just a quick rub down with simple green and damn I was impressed that they hooked up just fine on my sandy street. Update: this has been a great tire I agree with Darrin below probably will want to run a belted tire for outlaw but for a 2.9 or 13.5 Street type tire in the 40-50mph range it is great. One coat of get stuck soft and grippy transforms these tires! Concrete or clean asphalt they work great.
Tried the green compound to replace my worn out blues. Mounted up to the mambos beadlocks nicely. On an outlaw car with 60mph+ trap speeds these tires are completely unusable,great traction but they ballon a ton making the car very unstable. They would probably work great on a 13.5 car or even a 3 second index car but not for outlaw.
Ran these a few passes now on my drag car. So far they have ran pretty dang good. Only thing they get cool quicker than others I've used but would use them again for sure.
Reviewers report good traction on street-type and 13.5-style drag cars, with one reviewer noting the tires hook up well on sandy asphalt after a light cleaning. One review mentions a visible seam in the tread that a serious racer might sand off before running. One reviewer found them unusable on an outlaw car at 60mph+ trap speeds because they balloon and make the car unstable, suggesting belted tires for that class. Another reports they cool down faster than other tires they have used. Reviews refer to the green variant; the listed gold variant is not specifically discussed.
