In this video I will explain: 1) The meaning of the acronyms shown on the tire; 2) The concept of grip, smoothness and rolling resistance; 3) The characteristics of a tire (compounds, section, design and weight); 4) Which tire to choose based on your needs or ground conditions; 5) The concept of tubeless ✍ SUBSCRIBE ✍    / mountainbikingtube   ☀☀☀ FOLLOW ME ON ☀☀☀ ▶ STRAVA:   / strava   ▶ FACEBOOK:   / mtbt123   ▶ INSTAGRAM:   / mountainbikingtube   ▶ TWITTER:   / mtbtube   ▶ SITO: http://www.mountainbikingtube.com ▶ SITO: http://www.mtbtshop.com ✉ MAIL: [email protected] igle and labels ETRTO is an acronym whose meaning is (European Tire and Rim Technical Organization - European technical organization for tires and rims). ETRTO measures have two numbers e.g. this 50-622. The first indicates the width of the tire in mm and the second number indicates the internal diameter of the tire (622 mm). This indication is clear and allows a precise correlation with the size of the circle. To facilitate the conversion between ETRTO in inches, there are tables PSI / BAR: psi stands for "pound per square inch" and is the unit of measurement for pressure in the Anglo-Saxon system The bar is a unit of pressure measurement in the CGS system. 1 bar equals 14.5 PSI. TPI (Thread per Inch which translated means threads per inch) and indicate the density of the carcass tissue. Many threads = quality tire, smooth and light Few threads = more rubber and therefore more weight, more rigid and with a lower risk of puncturing Grip, smoothness and rolling resistance The grip has two main functions: 1) The first is to stick to the ground by not sliding over rocks or roots, especially in wet or muddy conditions. 2) The second feature is to give you traction and make sure that the rubber does not slip when you apply power to the pedals A tire with a lot of grip could however give you little smoothness, making pedaling more tiring and making you lose energy A higher or lower pressure could vary these parameters A deflated tire creates a wider footprint than the tire on the ground, offering more grip and creating more friction More friction, however, generates greater resistance of the wheel rolling, making us struggle more and spending more hernia Characteristics of a tire: 1) Compound: The compound is the magic element of the rubber. It is an alloy of caoutchouc and other chemical ingredients that affect density, rolling resistance, mud adhesion on rubber, wear and appearance. Two tires may look exactly the same, but if they use different rubber compounds their operation will be radically different. In general, the softer the compound, the greater the grip, especially in the wet. 2) Section: The section highlights the tire width, it is expressed in inches or as previously seen also with the European standard ETRTO. The larger the section, the more the footprint will be on the ground, increasing grip but also rolling resistance. MTB PLUS tires are very popular on E-BIKES, we can say that almost all E-BIKE PLUS mount tires with sections ranging from 2.60 to 3.0. 3) The Drawing: concerns the position, shape and height of the anchors and the cutting of the anchors. Putting a tire with more spaced blocks on the front and with a softer compound will optimize braking grip and offer greater safety when cornering. At the rear, on the other hand, a tire with thicker anchors is used to reduce rolling resistance. In principle, for muddy terrains the blocks will be very far apart so as to allow the mud to slide away from the tire 4) Weight: The impact on weight is given by the value of the TPI, which as seen above, is the value that indicates the density of the wires of the carcass. A high TPI such as 120 indicates that the carcass has many threads so it will be a light and quality rubber. If the rubber has few threads, it means that the tire will have more rubber and therefore will be more thinking and rigid. Which one to choose: If you ride on asphalt, you should prefer cycle touring tires, with thick and very low blocks. If you use pedaling on hard, compact and dry terrains, you do not need grip but more smoothness in order to make it less difficult. On muddy terrains, on the other hand, you need a rubber with grip, the blocks must be pronounced and well spaced And finally, if your paths are rocky, you will need a lot of grip, as the rocks are slippery. So it is better to use a rubber with high grip to have more friction on slippery surfaces #mtbt #mtb #mountainbike
