Tire pressure mountain bike

Mountain bike for me is a relatively new hobby , so forgive me if this sounds stupid, but how much it is important to follow the recommendations specified in the tire pressure ? Recommended values ​​seem to me much higher than required.

A: Tire pressure is the most important aspect for getting the most out of your mountain bike.
"There are a number of variables that influence the ideal pressure range . Some of these variables are beyond change , but we can at some very significant impact", – said the manager of sales in the North American region Schwalbe Henry Horrocks .

Maximum pressure for mountain bike tires is not where it bursts as a balloon, and that at which the destruction of the rim. Not all bike wheel and rim set up perfectly straight , some of them can withstand the pressure of 2 or even 3 times more than the other rim.

Based manufacturer of tires, has no way of knowing with what the rims will be used by their products . Therefore, the maximum recommended pressure is usually quite conservative value , taken with a good supply of strength.

"For mountain bikers the maximum pressure is usually not a problem, as most of the riders ride at a pressure well below that number.
Many , including myself, often ride at a pressure much lower than the specified minimum pressure on  mountain bike tires especially important when tubeless wheels", – said a spokesman for Schwalbe Henry Horrocks .

Why do pressure below?
Well, this will help your wheels roll faster , absorb more of the irregularities , add grip and comfort. There are many studies that confirm the above (although most of these studies have focused on measuring ride quality). When it comes to mountain biking, to find the perfect tire pressure – the primary task .
While the maximum pressure depends on the strength of the rim , the minimum recommended pressure is totally dependent on you, the rider.

If the tire pressure is too low may squirm , go to the rim or spit sealant. Driving with low pressure can also cause damage to the tires, there will be cracks and tire wear out prematurely . In the best case , the minimum recommended pressure  –  is it that will suit most cyclists on almost all the departures.

The range of the recommended pressure listed on the tire sidewall.
The variables affecting the performance of the tire can be divided into six categories , while the manufacturer can not influence them , you can.

Six of emphasis that should be considered when looking for your ideal pressure in the wheels.

• Weight cycling, for example rider weight of 65 kg per tire 26 * 2.25in at a pressure of 35 psi may seem that the tire has been pumped and lacks cohesion . However, the rider weight of 110 kg may seem that the pressure in the wheel is too low, floating on the tire rim and may even come off in the bend.
• The volume of the tire: the ratio of the tire to the pressure to feel comfortable squeezing her fingers. For example: 35 psi in the tire 700 * 25 mm will feel very soft and deep dents. And those same 35 psi in the tire 26 * 3.8 in will be felt as a rock , the wheel will bounce rather than absorb shocks .
• Coating: what are your trails? Fast and smooth or rocky with roots? If the latter then keep tire pressure higher, to prevent snake bites and blows to the rim .
• Riding style: how you drive is no less important than the one where you do it. If you have an aggressive style, then maybe you need to keep the pressure a little higher. If you have a neat style of driving , you carefully choose the path, do not lift your wheels off the road and possess good management technique, it overestimated the pressure you do not need .
• Rim width: wide rim plays an important role in determining the minimum pressure. The wide rim keeps the tire better than narrow. With the same size tires, wide rim allows you to go to a lower pressure without the risk that the tire will begin to squirm.
• Housing tires: the type of weaving tire affects its behavior just as well as the weight of the rider. Tires with a large number of threads per inch (TPI), is generally more flexible than those with less. You may find that you need to increase the pressure in the tires when replacing tires with low TPI on the tire with more TPI, and vice versa. In addition, models that are tough, reinforced sidewalls, as well as tubeless / UST tires as you may need a lower pressure to maintain the same level of performance and sensations which was more elastic tires.

Selection of the ideal tire pressure is by himself and his bike is an art, or, if you like, science. Remember these six aspects, take a pump with a pressure gauge and choose for themselves the best pressure.
