Technical Information

MAS Oval Tire 6"

The MAS tire is designed specifically for the North American dirt and pavement oval mark et.
The MAS tire was designed with the racer in mind.  By using the latest technology and feedback from racers we feel the MAS tire is superior to all other tires produced today.  

The advanced compound natural rubber tire works great straight out of the wrapper. 

The reduction in tire cutting, added preps and the long durability of this tire gives the racer  the performance he needs to win at a fraction of the cost.

 

*       Do not exceed  62 psi when mounting the tire to the rim.

*       Even though there is a triangle on the tire, the Vega MAS can be
mounted in either direction.  There is no directional rotation on the tire.

*       Air Pressure: Start with the same air pressure as you normally use.

USAGE

*       Resistant to heat cycles:  Testing has proven that there is little or no decrease in performance after several heat cycles.  This allows the karter to use the same tires over several weekends without a decrease in performance.

*       No need for tire cutting:  After extensive testing, the tire has been manufactured with the correct thickness of rubber for maximum performance without cutting.
