The tires of a gravel give it versatility, they are fitted with spikes of low height close to each other, their section offer a good compromise between comfort, grip and low rolling resistance on the road.
Constitution of a gravel bike tire:
The gravel bike tire consist of a thick tread in order to resist puncture due to the intrusion of flint or thorns. The tread is glued to this yoke, it consists of crampons intended for grip on roads and on land, it shape allows good water evacuation, they are rather close together to not limit rolling resistance on road.
Several criteria are used to determine the gravel tires correspondance with your use and your equipment.
Indeed, the width of the gravel bike tire must be compatible with the width of its rims, it section must allow the passage of the tire in the fork and inside the frame.
A wide tire section will allow good grip on the roads and bring comfort, on the other hand on the road it will create more inertia and be less rolling. Customizing the tire pressure value of your gravel will also determine its behavior and comfort on land and on the road.
There are also tubulars whose selection criteria will be rather similar to those of tires except for compatibility with the rims because they are glued on so the width of the rims does not condition the section of the tubular. The advantage of the hose is that it can be driven at low pressures without the risk of a puncture by pinching, on the other hand, in the event of a puncture, it will be necessary to replace it in its entirety, unlike a tire in which the replacement of the air tube allows to leave.
