Aluminum Spares- NHRA Legal?
I've seen threads about this that don't seem to come to any conclusion. According to what I read, you can't use the spare TIRE, but the wheel is okay. This is out of the 2011 rule book. I don't know if the 2012 is any different:
Tires will be visually checked for condition, pressure, etc. and must
be considered free of defects by the technical inspector prior to any
run. All street tires must have a minimum of 1/16-inch tread depth.
Temporary spares, space saver spares, farm implement or trailer
tires prohibited. Metal, screw-in valve stems mandatory in tubeless
tires, front and rear, on vehicles running 11.99 or quicker.
Hubcaps must be
inspectors, who will
check for loose
wheels, worn or
oversize lug holes,
and condition of
spindles, axle nuts,
cotter pins, etc.
are prohibited on
any class car. The
use of ‚Äúspinner‚ÄĚ style wheels or any wheel design that incorporates
movable pieces while vehicle is in motion or stationary are
prohibited. Each car in competition must be equipped with
automotive-type wheels with a minimum 12 inches of diameter
unless Class Requirements stipulate otherwise. Motorcycle wheels
or lightweight automotive wire wheels must be equipped with .100-
inch minimum diameter steel spokes, properly cross-laced to
provide maximum strength. All spoke holes in rim and hub must be
laced. Omissions to lighten wheels prohibited. The thread
engagement on all wheel studs to the lug nut, or lug bolts to wheel
hubs, must be equivalent to or greater than the diameter of the
stud/bolt. Length of the stud/bolt does not determine permissibility.
(Example: A 7/16-inch stud must be thoroughly engaged through
the threads in the hex portion of the lug a minimum of 7/16-inch.)
Wheel spacer permitted. Spacer to be either hub-centric or lug-centric
and must fit with minimal clearance to retain concentricity. The wheel
spacer must not reduce the minimum permitted thread engagement
below the limits established by fastener diameter. (See example as
stated above.) No stacking of wheel spacers allowed. Maximum rim
width on any car: 16 inches. No rear wheel discs or covers permitted
in any category. Top Fuel and Funny Car rear wheels must meet SFI
Spec 15.3. Pro Stock, Top Alcohol Dragster, Top Alcohol Funny Car,
and Pro Modified (Comp) must meet a minimum of SFI Spec 15.1
I have two, and I don't want to have any trouble with the tech guys when I go.
