WHAT IS IT? The Tread Doctor is a heated tire-cutting
tool that promises to improve the performance of worn
tires by cutting new edges on the knobs. And thanks to
the new Sniper kit, it is also an effective grooving tool.
WHAT’S IT COST? $79.99 (Tread Doctor with Sniper
kit), $69.99 (Sniper kit only), $59.99 (Tread Doctor without
Sniper kit), $14.99 (replacement cutting blade), $13.99 ( 12
pack of grooving blades).

WHAT STANDS OUT? Here’s a list of things that
stand out with Hardline’s Tread Doctor with Sniper kit.
(1) Cutting. The Tread Doctor can be used two ways.
First, with its large blade, it can slice off a thin layer of
the acceleration edge of the rear tire with a scooping
motion down the vertical side of the knob. Cutting the
knobs vertically gives them a new edge while making
the knob narrower. The slices you remove should be
very thin to avoid knob flex. Second, with the Sniper kit
attached, the Tread Doctor becomes a tire-grooving tool.
By grooving an old tire, which has hardened, or a new
tire, which has too firm a rubber compound, a rider can
fine-tune his sneakers for different track conditions by
putting more biting edge on the face of the knobs.
( 2) Choices. Hard or intermediate-to-hard terrain tires,
especially ones with reinforced knobs with bridges, are
the easiest tires to slice or groove. Grooves provide extra
edges for acceleration and braking. Instead of shaving
the edge of the knob vertically, cut a groove into the
contact patch of the center knobs with horizontal
grooves and sipe the transitional knobs with 45-degree
grooves from corner to corner. Don’t groove the side
knobs. For MXA’s tastes, grooving is a better alternative
than vertical cutting.
( 3) Cutting. The Tread Doctor blade doesn’t cut as
much as it melts the rubber. The Tread Doctor Sniper
kit is held like a knife and with the depth stop resting
on top of the knob, you apply pressure as the horseshoe-shaped blade begins to melt the rubber. When
pressure is applied against the knob, the hot blade cuts
through the knob like a knife cuts through butter.
( 4) Extra parts. The $79.99 Tread Doctor comes
with the heating element, cutting blade, Sniper adapter,
resting stand and 10 horseshoe-shaped grooving blades.
You can also buy the Tread Doctor with the cutting
blade only for $59.99 or just the heating element with
the Sniper kit groover for $69.99.
WHAT’S THE SQUAWK? Our only complaint is that
the power cord is on the short side.
