Your tires are the first and only thing that connects you to the ground. This is also your first shock!
All too often overlooked by the novice, the tires are essential components of your bike. Of them depend comfort, driveability, performance, but also safety. Must still be familiar to exploit all their possibilities. It is recommended to opt for the best ATV tires
Commonly, you will meet the size in this form, e.g., 26 x 1.95 ” 26 “corresponds to the diameter of inches of its wheel and tire your 1.95” corresponds to the width of your tire.
If the width is normalized (ATV adult, the wheels are 26 “, 27.5” or 29 “inches in diameter), it is not the same for the section of the tire.
Thus, there are sometimes tire 1.75 1.95 widest tires themselves greater than 2.10.
Section tire is different according to the brand because there is no standardization in this area.
The most common sizes are between 1.40 and 2.60, which covers almost all possible uses.
For more precision in your search, be sure to refer to another indication printed on your tire named: ETRTO (European Tyre and Rim Technical Organisation). This evidence is controlled and standardized. It is shown in millimeters in this form: 50-559 50 corresponds to 50mm width at the studs. 559 corresponds to 559mm of diameter.
It is composed of the son of nylon or cotton more or less thick, braided. Some are thick and stiff, others thinner, lighter, more flexible and also more expensive.
Mountain biking, flexible carcasses offer more to the tire deformation of latitude. So you will get more traction and comfort by absorbing shocks.
The number that determines the flexibility of the carcass is indicated by the number of TPI, an English measurement showing the number of son per inch (1 inch = 2.5 cm). Above 100 TPI carcass is very flexible and the tire considered a luxury.
SCREED AND RODS
The screen covering the body is composed of a mixture of rubber and other chemical ingredients (such as silica) that affect the density, rolling resistance, traction mud on gum, wear and appearance.
Today, some tires have different hardnesses screen according to the tire area. It can, for example, be a difference between the tread and sidewalls (Bi-density, triple compound) to optimize grip and performance without sacrificing durability.
The rods: These are the two hoops that flatten the tire on the rim.
The rigid rods are made of steel son. They are intended for the entry-level tires (heavier) or the tires need to be perfectly maintained on the rim (trial tires, downhill), despite low pressures.
The flexible rods are aramid or para-aramid, including Kevlar, and are destined for high-end tires. Significantly lighter, they have the advantages often an easier mounting and a storage facility offering the possibility of folding the tire.
The rods and Tubeless Ready tires are concrete to seal the torque rim/tire.
All brands offer innovative solutions that continually incorporate new technologies.
Faced with these many changes, it is sometimes difficult to navigate.
To facilitate your choice, we have listed all the technologies for each brand.
The air pressure contained in the tire affects its dynamic characteristics. Small section tires should be inflated more than large parts, to prevent pinch flats. We must also keep in mind that the reduced Overinflation grip, traction, and comfort favoring performance on smooth terrain.
Conversely, by deflating the comfort and improves the adhesion because the surface in contact with the ground is higher. However, this induced a higher rolling resistance, therefore a reduced yield.
You have several options to inflate your tires: foot pump, hand pump, CO2 cartridges …
The role of a rear tire is to promote the motility. For this, it endows the aggressive studs on the thread. These are often perpendicular to the direction of travel, to bite the ground (shaped paving stones, round or square). The spikes are height less if the ground is dry and if the tire is designed to promote efficiency.
The front wheel is the director: it is large that it depends on accuracy and exceptional traction. For this reason, the cramping will be more aggressive, rather shaped guidance arrows, more pronounced on the outer edges of the tire (the area in contact with the ground, when the bicycle will be of the angle).
The section around 2.35 “, but aggressive side knobs round profile to keep advantageous. D Performance – Downhill
Grosse section with aggressive side knobs and well supported for maximum cornering grip, and solid center blocks to resist bending induced violence.XC braking – Cross Country
Rolling XC: crampons purposes and relatively small, averaging section and an often lightened carcass for minimum weight and maximum performance. For dry land and vehicles exclusively. 1.90 “to 2.15”.
Stony XC: more volume for better shock absorption. Double or triple density rubber and prominent side knob for better grip. Section between 2.0 “and 2.2” moderately spaced knobs for excellent grip in all conditions
Acclaimed by all motorsports, pneumatic technology has consistently invested Tubeless mountain biking. Hutchinson and Michelin have worked with Mavic to popularize this system in 1998-1999. The tubeless tire is happening in a tube.
The tire casing and rim form a sealed assembly through specific tire bead cores, the heels “clipped” on the shoulders of the side.
The rim itself must be completely sealed. Some are specifically designed for, while others may adopt a conversion kit.
The Tubeless limit the pinch puncture risk (shear chamber between the obstacle and the rim) and allows driving with lower pressures.
Tubeless Ready tires called were then developed to save weight retaining the tubeless tire bead so that snaps into the rim but by requiring the use of preventive liquid to waterproof the tire casing, which she is relieved and, Tube type approaches a carcass (air chamber).
