Shipping


Vista, CA
Depending on location & order size, we will ship either USPS Priority Mail, Fedex/Fedex Ground or UPS
Folding Bead (Trail Casing)
1-2 folding bead tires almost always ship USPS Priority Mail
3-6 Folding Bead tires ship USPS Priority, Fedex Ground or UPS
Wire Bead (Gravity Casing)
Wire beads nearly always ship Fedex Ground
Refer to the maps below for reference (if you live close to a day border, assume it will take the longer of the two)

 

Tube/Tubeless


Yes, all our tires are tubeless-ready, but you will need rim tape, a valve stem & sealant for them to work properly
Tubeless tires allow you to run lower air pressure and not worry about a pinch flat on your tube. Lower pressures allow for more surface contact &, thus, more traction
More traction = more better
Yes
Various tubeless valves are available. Stans makes a nice one; if you’re planning to install CushCore, you have to use their valve
That’s a massive topic of debate. In a pinch, black Gorilla Tape is a little heavy but works great

 

Casing & technology


Our Trail Casing is a single wall tire with a folding bead, generally what most people consider “normal” mountain biking.
Our Gravity Casing is a double-wall tire with a wire bead. These are heavy-duty generally for gravity riding like downhill racing or freeride terrain
If you’re wondering which casing you should get, you probably want a Trail Casing tire
Threads Per Inch, a measurement for the number of cords in an inch of tire casing. Lower TPI has higher gauge cords and a more durable carcass. A higher TPI tire has smaller gauge cords & is more lightweight
A soft-rubber impregnated woven mesh that resists both punctures & air leakage.
Think of it like an extra ½ layer of super-soft rubber laid between the casing & tread that acts as a shield, holding air in & helping to keep stuff out 

 

General Riding & Tread Features/Characteristics

You should check your tire pressure before every ride
(When you do, you’ll find that our tires hold air much better than other brands)
We designed it to work on either. The accordion folds and siping give excellent traction whether you’re turning, accelerating or braking
Yes
Both a unit of measure and an instrument to measure the hardness of rubber
The folding bead/trail compound has a 63a durometer in the middle & 60a durometer on the sides

 

The wire bead/grip compound has a 59a durometer in the middle & 52a durometer on the sides.
Generally, a tire made of a higher durometer has better tread life, and a tire made of a softer durometer has more grip. Durometer hardness is only one of many compound properties for tires. Other variables such as rebound, tear resistance, chemical composition, tread pattern, siping & casing design all work together to determine a tire’s ride characteristics
Small grooves or recesses in the knobs of tires that allow them to conform to the terrain
Angled approaches on the front of our center knobs allow the tire to roll with less resistance (faster)
Small fold lines molded into the leading edge on the side knobs of our tires which allow the tires to conform to the shape of the terrain, providing more traction

 

General


Versus tires are not specifically tested or classified for ebike use, but our 60 TPI casings & VERSA layer should work if you choose to do so.
