Front and rear tires perform di
ff
erent jobs and can wear di
ff
erently, depending on the tracks driven. To get maximum life,
rotate every two weeks or 200 hours of operation.
WHEN IS IT TIME FOR NEW TIRES?
You can see cord or fabric showing.
Sidewall is cracked, cut or snagged deep enough to show cord or fabric.
Tire shows a bump, bulge or split.
Tire has puncture or shows other damage.
Wear lines are worn down past the last line.
SHOULD I PUT NEW TIRES ONLY ON FRONT OR REAR OF KART?
You should always replace all four tires. Replacing only the front or rear will cause the go-kart to be unbalanced.
Example: Placing new tires on the front and leaving worn out tires on the rear will cause the kart to ride high in front
and low in the rear; this could cause the kart to ride over the containment system, or over or under other karts. When
replacing tires, all four tires should be replaced at one time.
CAN I MIX AND MATCH TIRES?
Ideally, tires should be of the same type and design, have the same tread depth and be in
fl
ated to the correct pressure.
Frequent tire questions:
WHAT IS THE PROPER INFLATION FOR MY BIGFOOT TIRES?
J&J RECOMMENDS 40-50PSI (276-345KPA).
WHAT DOES THE DIRECTIONAL ARROW ON THE SIDE OF THE TIRE MEAN?
Nothing; the arrow was used in the early days on treaded tires. Bigfoot tires can be installed with the arrow going in either
direction.
IS IT EASY TO SEE WHEN MY TIRE PRESSURE IS LOW?
Tire pressure is very di
ffi
cult to judge by sight alone. Tires can be well under 30% in
fl
ated before it’s noticeable to the eye.
This is why it’s so important to check your tire pressure daily with an accurate tire gauge.
WHAT SIZE ARE MY TIRES?
There are two popular methods of identifying tires.
1.
The
fi
rst is overall diameter x section width x rim diameter (example 12 x 4.00 -5 (A,B,C).
2.
The second method is section width x section height x rim diameter (example 3.40 x 3.00-5 (B,D,C).
