Michelin "surprised": Does Suzuki and Yamaha prefer new rear tires?

 Michelin Michelin was surprised to find that the in-line four-cylinder engine could cope better with the new tire - but it is expected that the V4 bikes will also find advantages. Michelin has developed a new rear tire for the 2020 MotoGP season. The new design is primarily intended to offer more grip. This tire was tested by the teams on various routes during the previous year. This tire was tried on the test days in Barcelona, ​​Brno, Misano, Valencia and Jerez.

What's going on? Read on to learn why that same tire keeps losing air. Nothing is more annoying than stopping to fill an under-inflated tire every week or two. Of course the first thing you look for is a puncture or tear. It's normal for tires to lose a few PSI (pounds per square inch) of air due to temperature changes. However, if temperatures remain consistent and your tires constantly lose pressure, there is a leak that needs attention.

Do you keep getting a flat tire and can’t figure out why ? Odds are it isn't just bad luck. We look at why your tire keeps going flat . For those who think tire levers are tire levers, they’ve never seen anything like this set. With a unique shape that not only protects your hands when removing stubborn tires , but also prevents pinch flats , the Speedier tire levers even have written-on instructions on which side to use for removal or installation.

Nothing is more annoying than stopping to fill an under-inflated tire every week or two. Of course the first thing you look for is a puncture or tear. It's normal for tires to lose a few PSI (pounds per square inch) of air due to temperature changes. However, if temperatures remain consistent and your tires constantly lose pressure, there is a leak that needs attention. Age, exposure to contaminants and stress can cause parts of your tire and rim (wheel) to fail. But what do you do if your tire is not visibly damaged? Consider that one of these problems is causing your flat tire:

Sharp Objects

Running over any sharp object can puncture a tire. A tiny nail can puncture a tire, then fall out, causing a slow two-to-three PSI leak per week.

The Friction Circle Tells You What Your Tires Can Handle; Here's How It Works

  The Friction Circle Tells You What Your Tires Can Handle; Here's How It Works How well you grip the street is determined by the friction circle.You’re on the street and you’re alone. Spanning the horizon, you see the sun cresting and one glorious corner after another. Some are slow, others are fast, with a few nice straights in between. Tire pressures checked and adjusted. Engine warmed up. Gas tank full. It’s time to experience driving ecstasy.

If tires are going flat over entended periods of time, like a trailer in storage, for example the tires can and do dry out over time, most have a shelf life of roughly 5 years. Seasonal changes can cause the rubber to exp. If your tire is going flat over a period of a few days, it could be a slow leak via puncture, valve stem, rim seal, or an abrasion to the sidewall. Tires are made with at least two types of rubber, the exterior, for traction and structure, and the interior, which retains the air. Damage to the sidewall (hitting curbs, driving on a flat ) will breakdown the interior rubber.

But NO, the tire was going flat . Does anyone know why ? I found a nail in it the other day, so I took it out, and thought everything would improve. But NO, the tire was going flat .

Valve Stems

Made from rubber, valve stems can deteriorate over time. They also can be damaged from hitting a curb or even from an automatic car wash brush. Keep your valve stems clean and always replace the valve cap, but don't overtighten it. Overtightening the cap can damage the valve core. Hand-tight is tight enough.

Ripped Tire

A ripped or torn tire is unsafe, especially if the rip is on the sidewall. Driving on a weakened tire, even if the leak is minor, is dangerous. Compound that with an under-inflated tire that can overheat and you've got a prescription for a blowout.

Bead Leak

The bead is where a tire seals itself to the rim. The bead on older tires, or tires that have "dry-rot," may have decreased elasticity and no longer seal properly. Beads can also be damaged when a tire is mounted or dismounted without the use of tire lube and beads can become chaffed, due to a corroded rim. The only fix for a damaged bead that cannot seal to the rim is a new tire.

Car Care and Maintenance During the Coronavirus Outbreak

  Car Care and Maintenance During the Coronavirus Outbreak Consumers have many worries right now during the coronavirus outbreak. Somewhere on the list for some is keeping their car dependable, especially for those who work at “essential” businesses and need to commute.  There are many basic car care tasks, such as checking fluids and inspecting tires, that can be performed in your driveway. And in an ideal world, you would have been ahead of all routine services and repairs, such as an oil change, before social distancing.

I recently bought a 2010 Mongoose Maurice. While riding, I rode up a gutter with speed and my back tire went flat . I then continued on my ride.It was going good until I rode up another gutter with speed and blew the back tire again. The next day I took my bike in to a different shop and they replaced the tube.

When you go to jump on your bike, you expect it to be ready to go – what you don’t expect is to have to waste time changing your tire . Unfortunately, it is inevitable that you will experience a flat tire at some stage in your cycling career, therefore, it is important that you ensure you are well prepared to, firstly, identify the reason your tire is flat and, secondly, have the knowledge and tools necessary to We’ve just reduced the price of our 71 page ‘Bicycle Commuting Handbook’ by 50% for a short time.

Rim Issues

Corrosion where the rim meets the tire bead is a common cause for a tire losing air pressure. Die-cast aluminum and magnesium alloy wheel are more susceptible to corrosion. Be sure your tire technician inspects the area where the wheel and bead seal before installing new tires. As well as being unsafe, even a new tire will never properly seal to a badly corroded wheel.

Often overlooked is wheel porosity, where air leaks through the rim itself. Usually caused by a poor casting or corrosion from using incorrect wheel weights, there is a proper, accepted way to repair this type of leak. Don't inject your tire with tire sealant to fix a leaky rim. It can be extremely difficult to clean out and can ruin a repairable tire or tire pressure monitoring system sensor.

Over-inflated Tires

You are playing a dangerous game if you think that by over-inflating a tire with a slow leak, you will increase the time between fills. Besides a rough, noisy ride due to stiff sidewalls and tread, an overinflated tire wears quicker, and overall tire performance suffers. Rigid, overinflated tires are unstable, lose traction easily due to reduced tire-read-to-road contact area (think of a basketball) and make sidewalls vulnerable to blowouts when hitting a pothole.

Friction Varies With Temperature

  Friction Varies With Temperature Friction Varies With Temperature depend upon the blends of materials used. Early friction materials contained such ingredients as cloth, horsehair, and tar. Film of the 1906 auto Grand Prix of France shows an explosion of smoke from one car’s clutch at the start, as rapid heating of the friction material vaporized its binder. Considerable progress in friction materials has been made in the intervening 114 years. © Pirelli Slick tires warm up more slowly and need tire warmers to keep them at operating temp before heading out on the track.

Throughout the summer I have had 4 flat tires . I have changed the inner tube each time, and they all keep going flat . There are just so many reasons for flats that it is difficult for us to pin point it there without actually looking at your wheels. Given all the advice above here is what I suggest: Take off your wheels and clean the rim with soap etc. Wait till it is completely dry, put a tape on the inside (they sell them at bike stores, don't use electrical if you don't know what you are doing , ghetto methods aren't always best).

fill the tube with air, immediately immerse it in water look for the bubbles, mark it then line up the valve to the hole in your rim, look in the area on the tire where the tube leaks for thorn or check the rim itself for something sharp. check the opposite side also in case your tube was installed flipped Source(s): Some bike shops don't 'believe' in thorn proof tires . I believe they don't believe in them so they can sell more regular tubes.

Road Hazards

Anything that can damage a tire or rim — punctures from a nail, metal fragments, broken glass, a piece of wood, a cracked rim or sidewall rips from hitting potholes or a curb — are considered road-hazard damage. Only your tire technician can determine which of these are repairable.

So, as you can see, there are a lot of reasons why your tire can go flat. Inspect your tires and check air pressure at least once a month. Properly inflated tires last longer, wear more evenly and are safer to drive on.
