Technical Information

MBS Yellow 6" Oval Tire

The MBS tire is designed specifically for the North American dirt and pavement oval market.
After extensive research, development and track testing, the MBS tire fulfills the needs of North American oval racers.
The MBS tire was designed with the racer in mind.  By using the latest technology and feedback from racers we feel the MBS 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 4 bars or 62 psi when mounting the tire to the rim.

  • Even though there is a triangle on the tire, the Vega MBS 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. 
    Some karters have used 1 to 1 1/2 PSI more air than they normally use.

USAGE

 We know you are accustomed to prepping tires. This tire has been designed for maximum performance without the need for prep.  Please try your new Vega tire without prep. If you feel the need to experiment with preps, we recommend you have a set which has not been touched by prep to go back to. At this time, we have used only water to clean tires and wipe with clean towel.

 The Vega tire has displayed very positive results in several areas. 

  • Performance:  The new Vega Oval tire, straight out of the wrapper, has tested to be as fast or faster than the current spec tire that has been cut and prepped.

  • Excellent wear:  The special natural rubber formula has increased tire life 2 to 5 times over the current spec tire. 

  • 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.

  • No need for tire prep: The latest technology rubber formula provides race winning performance without the addition of tire preps.  Testing shows that the addition of prep does not enhance performance.
