THE CARE AND FEEDING OF YOUR TOYO RA-1 D.O.T. HIGH PERFORMANCE TIRES
TOYO RA-1 tires have proven themselves to be the
most consistently performing tire over it's life span, more than any
other performance tire in the world.
TOYO RA-1 tires are unique in the high performance
industry in that they do not require a "heat cycle" process to increase
the life of the tire.
However, it is known that TOYO RA-1 tires can become
"greasy" during the first 2-3 heat cycles.
Once this "break-in" period has passed, the TOYO
RA-1 tire will post consistently quick lap times for the remaining life
of the tire at each and every event.
Therefore, it is recommended that you allow the TOYO
RA-1 tires 2, 3, or 4 heat cycles before expecting you best (quickest)
lap times.
PRESSURES:
We've found that the TOYO RA-1 tire performs best
with a "hot pressure" of between 38-42 lbs.
Ideally, you should set the "starting pressure" at
approximately 30-32 bls
A "starting pressure" is not a "cold pressure", but
the pressure that you should set the tires to prior to entering
the track for practice or a race. At any time of day or night.
Depending upon the driver's style of driving, the
type of car, the vehicle's rim width and the tire size, the type of track
and/or the chassis settings, these starting pressures can vary by
4-5 lbs lower or higher.
In cold weather, it is recommended that the starting
pressure be between 27 and 29 lbs with an ending or "hot" pressure of between
35 and 38 lbs.
Starting with too LOW a tire pressure will cause
the tire to become overheated during the later stages of the event.
The result is that the tire will "go off" or begin to loose traction.
Extremely low tire pressure (below 20 lbs) could cause sidewall damage.
TREAD DEPTH:
At full tread-depth, the inner two grooves
of the TOYO RA-1 tires are 8/32nds of an inch deep, and the outer 2 are
6/32nds of an inch deep.
At full tread-depth the TOYO RA-1 is famous for it's
performance in the rain.
Rain pressures should be about 5 lbs lower than the
"dry" starting pressure
At full tread-depth the TOYO RA-1 is an awesome performing
street tire.
Shaving the tire eliminates what is called "tread
squirm" and allows the tire to react quicker to driver input and vehicle
directional changes.
DIRECTION AND ROTATION:
The tire rotation directions indicated on the sidewall
of the tire are important for water drainage in rain or wet conditions.
However, the direction of rotation can be changed
to suit the driver's needs once the tire has been shaved and/or worn down.
Thus, you may use the tire in any direction of rotation when not in
rain or wet conditions.
TIRE DAMAGE:
The most common tire damage is when the tire/wheel
combination strikes the edge of a pot hole, a curb at the side of the track,
or the edge of the pavement. If the driver should drop a wheel over
the edge of the track and the track's edge is higher than that of the pavement,
the sudden sharp impact could cause the bead area of the tire to become
broken. Should this happen, a bubble will appear on the sidewall
of the tire. CHANGE THIS TIRE IMMEDIATELY.
WARRANTY: We regret to inform you that because the
TOYO RA-1 is used in competition event there is no implied or written warranty.
ENJOY THE RIDE!
