Does the 700 x 40 have tan sidewalls? No. This variant has black sidewalls.

Mechanic Compatibility Guide: Teravail Cannonball Gen 2 700 x 40
What exactly is this product? One Teravail Cannonball Gen 2 700 x 40 gravel bicycle tire, ISO 40-622, with black sidewalls, Durable 120 TPI casing, Fast compound, folding bead and tubeless-ready clincher construction. Manufacturer part number 19-000780; QBP TR00019; UPC 708752534926.
Which wheel does it fit? A compatible clincher rim with a 622 mm bead-seat diameter, commonly called 700c. Diameter alone does not establish fit: confirm the rim manufacturer's approved 40 mm tire range and the bicycle's frame and fork clearance.
Will it fit my gravel, road, cyclocross or hybrid bike? It can be a candidate for a bicycle using compatible 622 mm rims and adequate clearance for its actual inflated width. Do not claim compatibility with a particular bicycle model or year without checking its rim specifications and clearance. A 700c wheel does not guarantee clearance for a 40 mm tire.
Does it fit 650b, 27.5-inch or 26-inch rims? No. Those rim diameters differ from this tire's 622 mm bead-seat diameter.
What is needed for a tubeless installation? A compatible tubeless rim, suitable rim tape, tubeless valve and tire sealant. Verify the wheel manufacturer's tire compatibility requirements. These installation supplies are not included with this tire.
Is hookless compatibility confirmed? Not from the available QBP listing. Check Teravail and the exact rim manufacturer's current compatibility guidance before recommending a hookless setup.
What pressure should I use? QBP lists 50 PSI. Never exceed the lower applicable tire or rim pressure limit. A riding-pressure recommendation requires rider and load weight, rim width, terrain and installation details; do not treat 50 PSI as the correct pressure for every rider.
What riding is it suited to? General gravel conditions, gravel racing and mixed-surface riding. The directional center tread supports rolling efficiency, and shoulder knobs support cornering traction. It is not a studded winter tire.
What should the mechanic ask before confirming fit? Bicycle make, model, year and size; wheel and rim make/model; rim bead-seat diameter and internal width; hooked or hookless rim; available frame and fork clearance; tubeless or tube setup; rider and cargo weight; intended terrain.
What does the customer receive? One tire, not a pair, wheel, tube or tubeless installation kit. Listed tire weight is 525 g. Supplier photos are representative Gen 2 images and may show a 700 x 45 marking; the item sold here is 700 x 40.
