  DeCuzzi Tire guarantees quality, performance and durabile Kart Tires
Outdoor advice? 
        Tracks with little adhesion usually require a higher tire setting. At first, it is recommended to inflate the tire air pressure between 13 and 15 PSI (hot tire). For circuits with too much rubber on the ground, usually a situation where there are too many karts on the track, it is recommended to use a lower tire setting 10 a 13 PSI with (hot tires). Keep in imind, weather changes have influence on the kart's behavior. Tires with a softer compound may require a setting lower than tires with a harder compound depending on the weather. Indoor kart facilites need .to start with a higher tire pressure 24 thru 30lbs cold. The heavier weghts of in door karts will cause cord separation inside the wheel if proper tire pressure is not maintained.
   
             
Test Procedures
        Please clear all data from the kart to make sure you get an accurate read on the number of laps our tires provide. Compare them to what you get now, the quality performance and longevity! We have multiple compounds! Every time we send a sample it becomes the most used kart in the fleet, please double check to make sure you get the same results as all our other tracks! A 20% longer wear with unlimited heat cycles!  Outdoor facilities start tire pressures at 13 to 15 PSI , indoor facilities start at 24 to 30 PSI and work your way up or down according to how it handles.    
             
    Handling Tips    
        Width:
A wide front track will add grip to the front end. It will also help the kart rotate in the corner due to the "jacking effect" which occurs when the wheels are turned into a corner. This concept can be seen easily when the kart is on the stand, by turning the steering wheel, you can watch as the inside tire goes down and the outside goes up, the "weight jacking" allows the inside rear wheel to lift up much easier, allowing the kart to rotate as it is powered by the outside rear tire. The wider the front track, the more pronounced (the "jacking effect") Narrow front track width will result in less scrub, providing better turning speedn up front. A loss of the "jacking effect" is the trade-off. While the front will track around the corner better by getting more grip, without the lifting of the inside rear wheel, the kart will not rotate in the corner.

   
    Front Ride Height    
        High Frame:
To raise the chassis, lower the spindle in its carrier by moving the washers from the bottom to the top. By raising the front ride height, you effectively raise the center of gravity in the kart and will increase the side bite on the tire, making it grip harder. If you go too high however, the raised center of gravity  will make the kart "bicycle" or lift up its inside wheels. 


Low Frame
To lower the chassis, raise the spindle in its carrier by moving the washers from the top to the bottom. By lowering the front ride height.  This will take side bite away from the tires and allow them to slide instead of grip. This will decrease the grip in the front-end. 


   
    Air Pressure:    
        Air pressure is one of the most powerful tools we have available to us for trackside tuning. Lets look at some effects of changing the tire pressures on the kart's handling.

Raising Rear Pressure:
This decreases grip on rear of kart and “loosens the rear."  This will free the kart up in the corners. This  will not increase front bite on a pushing kart, but will help to balance the front and rear. This could help to make a pushing kart at least drivable if everything else has been tried. 


Raising Front Tire Pressure- Decreases Grip on the Front of the Kart:
I
 would keep raising front tire pressure until the kart started to push, then back off. High tire pressures give more speed (less rolling resistance). Using higher tire pressures (all the way around) usually helps "free" up the kart, provided a good front to rear balance has been attained and helps increase the life of the tires.

Under Steering / Over Steering:
Raise rear tire pressure about 3 psi to correct under steering and lower inflation pressure in the rear tires by the same amount to counteract over steering. The opposite is also true for front tire inflation pressure. This should not be changed, however, because tire stiffness caused by the proper inflation, pressure is needed on the front wheels.
