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.

Keep fit and save money by using your bike for more things like running errands and commuting to work. Surprisingly, there are a number of reasons your tire can go flat . Some of the most common reasons your tire will become flat include

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 .

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.

My rear tire on my mountain bike has gone flat 3 times within a week, the first time the bike was locked outside for about 20 minutes after I had ridden it a few miles and I the 2nd time the tire went flat a few days later I heard the air being let out while I was riding it and there was a inch long rip in the tube.

I got a flat tire out riding yesterday and got an new inner tube while I was out. It's the same kind I always get, proper size. I put it in and got from my One very common scenario for a tire that keeps going flat is that double sided tap that sits on the inside of your rim is old and not sticking so your tire

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.

Throughout the summer I have had 4 flat tires . I have changed the inner tube each time, and they all keep going flat . I have checked the inner rim and inside of the tire , but nothing has caught my eye. Any suggestions?

I have changed the inner tube 5 or 6 times on my cruiser bike and it still won't hold air for more than a day. I have checked the rim and tire for flaws or thorns etc what could be causing this? The rear tire is fine.

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.

If a tire repeatedly goes flat in cold weather there is a good possibility of a leak at the bead where it seals against the rim. If it is going completely flat you have a leak and need to get it patched. It might be the valve stem. To check this (kind of gross but hey it works) if the tire is full wipe some spit where

Why do my new tires keep going flat or popping? Because you pissed your xboyfreind off. I worked construction years ago, we didn't go look for stray nails or screws when they went flying.

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.
