Front Tires

GlennLever:
The Gentleman that stopped at my pit yesterday did not pass tech because there was a max 30 MPH speed on the side of his tire. The reason I passed is there wasn't one.

JakeB23:
Congrats Glenn for getting into the final!

Nice looking car and great driving!

Thanks, I gave it away.

I was running a 10.0 car at night saw his light and left (2 seconds early)

I wrote to NHRA,

"Sir,

At Bowling Green, at tech inspection they were looking at front tires on dragsters that had tread. They were particularly looking for "MoPed" tires and tries with "max MPH limitations". My front tires were gone over with a fine tooth coom and neither of those marks were on them. The inspectors were looking for "For Racing" on the side of the tire, but my tires did not have that. They passed it anyway because there was no "MoPed" or "max MPH limitations".

A gentleman on my forum supplied this input. "Just looked up the rules concerning front tires within the Heritage series, Falls under general regs 5.1 & 5.2 as applies to any NE Class and Jr Fuel and that reg does not mandate racing front tires. Now 7.0pro states manufactured racing tires but does not specify front tires also as does the spec for Fuel and Funny mandating front tires designed for racing."

In the NHRA Rule book under Nostalgia Dragster "Class of competition within Nostalgia Dragster is for front-engine,
methanol-burning dragsters." I find

TIRES & WHEELS: 5
TIRES
Maximum width 12 inches as measured across tread surface or
indicated by manufacturer on the sidewall. See General
Regulations 5:1.
WHEELS
Lightweight automotive-type wire wheels permitted on front axle
only, provided total car weight does not exceed 1,800 pounds,
excluding driver. Maximum rear wheel width 12 inches. See
General Regulations 5:2.

In General Regulations 5:1 and 5:2 I find

TIRES & WHEELS: 5
5:1 TIRES
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.
5:2 WHEELS
Hubcaps must be removed for inspectors, who will check for loose
lugs, cracked wheels, worn or oversize lug holes, and condition of
spindles, axle nuts, cotter pins, etc. Snap-on hubcaps are prohibited
on any class car. The use of “spinner” 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
Diameter of stud At least diameter of stud Washer Lug nut
5:2 Section 20 - General Regulations 20.27
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.

and never heard back.

Not willing to take a chance on travel and then not being able to race.

Baby has new shoes and shoe laces (stainless steel cotter pins)





I was more concerned about tread depth than type of tire as there is a stipulation on tread depth in the rules.

S&W Racecars in Pa sells the Kendas for $30 some $$ a piece--I see the same tire sold elsewhere upwards of $70--they do not have any Moped markings or MPH limits and are on lots of cars. I have heard from several folks that real Race Goodyears etc are NOT a safe deal on wire wheels that most of us run due to ???? Something about the way the bead and wheel lip is not compatable??
I love my Kendas and I love that I got them for fair price--they look great also!
Those tires shown Looked like moped tires and would have drawn a look from any tech guy I would think
THANKS for askingthe tech guys to clear it all up so we can all be safe and pass tech
I had my first encounter with NHRA tech when I got my chasssis serted--NEW guy--I think I knew more than he did --he got hammered by the 15 guys that showed hoping for new stickers --they shreaded him alive as they were certing old cars that had been racing every wk end since that guy was born--it was a POOR showing by NHRA and...we were told we would slpit his travel expenses between the number of cars --well that would have been minimal per car but they "cut it off" at 6 or so cars so we All HAD TO PAY A BIG CHUNK --  not fair or a good show--we can't race and give NHRA money without the sticker yet they gouged us on that too. I may just keep on running my local stuff and avoid the NHRA--My first impression was not a good one so guessing the tire deal was BS too.
