These days I am informed on the web to try to understand that tires mounted on my bike because the tires are finished.

I found several articles, I post one

Choosing appropriate and ideal tires is a bikers’ – both beginner and expert, most discussed quandary.  When you think about it, tires are extremely important because they provide the connection between bike and terrain. We can have the best bike with the most incredible suspension in the world, but if we install low quality or less than ideal tires, the bike won’t perform well at all.

We know tires are important, but what are the standout features of a good tire? Low rolling resistance? Traction? It’s a tough question, and there isn’t one single, perfect answer… it depends on what you’re looking for: low rolling resistance or traction, a hard tire or a specific tread for a certain terrain. That one miracle tire simply does not exist.

There isn’t one perfect tire because each terrain requires a specific tread, compound and casing. So, how does one make the right choice?

Dry/Hardpack terrain

Let’s start with the typical conditions during the best season on our trails, summer: firm, dry and dusty ground, on well worn earth.

CHARACTERISTICS OF AN IDEAL TIRE

On hardpack terrain we don’t need a super aggressive tire because the ground already provides good grip. You typically want to choose a tire with faster rolling resistance to increase pedaling efficiency, especially on high speed sections.

A deep lug (too knobby) tread is useless and becomes a disadvantage. Tall knobs, especially with a soft compound, tend to wallow on hard ground because they can’t bite into it. This results in more rolling resistance and less traction, particularly in tight turns where the knobs squirm and fail make sufficient surface contact.

Tread:  short knobs, tightly spaced, better if ramped.

Width: super wide tires aren’t advantageous. It’s better to chose a narrow tire to improve rolling resistance and lower rotational weight to help you save energy.

Compound: a compound that isn’t too hard or too soft but has good wear properties, firmer knobs and low rolling resistance.  

Loose over firm terrain

Firm and mainly rocky with loose top soil, in dry conditions tends to form a pebbly layer on the surface which can actually be really slippery.

Typically found on popular mountain trails for bikers and hikers, well worn terrain with this pebbly superficial layer is really tricky. It seems to offer good traction, but as soon as you try to brake or corner at high speed, the bike slides out without warning. On hard ground the knob can’t penetrate and the pebbly layer makes the tire slide, so on this type of terrain handling the bike is really tough and often unpredictable………………..to be continued, link  mtb-mag.com
