Tires can explode from overheating, general wear and tear, being made to carry too much load, or being put under too much stress. So if Airplane tires have to carry very heavy loads, can be retreaded up to 7 times and undergo at least 500 landings before each retread, and experience extreme stress and heat during every landing... Why don´t Airplane tires explode? On the outside, an airplane tire may look a lot like any other tire, but in fact, they are completely different Composition. In order to withstand the extreme stresses they have to, an airplane tires are made by combining layers of different materials, these materials are synthetic rubber compounds, aluminium reinforcements, nylon fabrics, steel reinforcements, and aramid fabrics. Aramid fabrics are strong, heat-resistant fabrics used in ballistic-rated body armor and other military and aerospace applications. Conductive Rubber. The synthetic rubber used for airplane tires is called conductive rubber, meaning that it can actually conduct electricity. On a modern aircraft, there are hundreds of electrical components and sensors that are very sensitive to electrical discharge. During takeoff and landing, the friction of an Airplane's tires creates static electricity, should this energy suddenly discharge it could interfere with or damage these sensors and have catastrophic consequences. The conductive rubber allows the tires to conduct that electricity into the ground and therefore avoid a potential build-up of static and its subsequent discharge. Nitrogen. Aircraft tires have to be inflated to 14 bar in order to carry the burden of the massive aircraft above them, they also have to endure extreme pressure changes and drastic temperature changes. During a normal flight, a tire's temperature can go from -40ºc to over 200ºc in a relativity short period of time. Normal pressurized air is affected by temperature change, it's corrosive, and, it's flammable. So in order to reduce the level of expansion and contraction that the tire suffers during these changes, reduce internal corrosion, and lower the risk of an explosion or fire, airplane tires are actually filled with the inert gas, Nitrogen. Safety Measures Airplane tires are also equipped with some pretty ingenious safety devices. As we mentioned before, aircraft tires have to endure extreme pressures and heat, even though they are filled to 14 bar, the tire itself has to be able to withstand 4 times that pressure for at least 3 seconds in order to be deemed "Safe". In addition to this, most aircraft wheels are equipped with an OPRV, Over Pressure Relief Valve to release the tire's pressure should it exceed a safe level. Another safety device wheels have is a Thermal Fusible plug. This plug has a central core made from a metal that has a low melting point, normally lead or tin. Should the wheel or tire exceed this temperature during a heavy braking situation, the inner core melts, slowly releasing the tire's pressure and therefore reducing the possibility of an explosion and improving braking by increasing the friction the tire has with the ground. Circumferential Grooves Airplane tires don't have the intricate tread patterns that car tires do, just some circumferential grooves, oddly enough, this is also done to stop them from exploding. A tire's tread is designed to evacuate water from the surface beneath it to increase traction and avoid aquaplaning. The horizontal tread that we see on a car tires design doesn't appear on an airplane tire because the average aircraft's tire hits the runway at 150 mph and it must accelerate to that speed as it is dragged along the runway, this stress would literally rip the block-like car tire tread from the tire and possibly cause it to explode. Also, aircraft really have no need for the horizontal tread anyway. The horizontal tread is designed to evacuate water as we go around a bend giving us traction when we corner at speed. Should you ever be in an airplane that's cornering at speed, aquaplaning, probably isn't your biggest worry!

According to German law, a pillow can be regarded as a passive weapon. Injure someone with a pillow and you could be charged with assault. Unless of course, it's on International Pillow Fight Day. 2. No Drilling on Sundays Germans take the day of rest seriously, and no loud activities are allowed on this peaceful day. Vacuum at your own risk. 3. Avoid Talking about the War Most Germans believe the war to be a huge embarrassment to their nation, and would rather not discuss it. Never do the Nazi salute as it’s an imprisonable offense in Germany. 4. Don’t Close Your Door to a Chimney Sweep It’s actually illegal to refuse entry to a chimney sweep, and all Germans pay for this service whether they have a chimney or not. The law stems from the Middle Ages, but was reinforced back when Hitler used them as a network of spies. 5. Don’t Sing the Original First Verse of the National Anthem During the Nazi era only the first verse was sung. In an effort to distance themselves from Nazi connotations, the official anthem is now the third verse. Pete Doherty once made this highly inappropriate mistake and was booed. 6. Don’t Run Out of Gas Doing so on the superhighway can lead to fines. The law is primarily against unnecessary stops, but has been applied to fools who drive without adequate fuel. 7. Never Walk in Bicycle Lanes Most German cities have plenty of these; numerous cycle lanes for people to get about. However walking on them is not only extremely annoying to pedal pushers, it can be downright dangerous. 8. Don’t Be Late Being late to appointments is severely frowned upon. The more relaxed attitude typically found in southern European countries simply doesn’t cut it here. Aim to be punctual if not a little early. 9. Don’t Keep Your Shoes on in Homes Taking your shoes off when enter somebody’s home is widely expected in Germany. Hosts will often provide you with some indoor house shoes. 10. Never Drink Without a Toast Germany is famous for its beer scene, however it is considered bad form to take the first sip without giving a toast. Usually a toast is as simple as saying “Prost” (cheers!) Make sure to keep eye contact as not doing so is believed to bring bad luck. Now you know what NOT to do, enjoy your time in Germany! Prost! ... https://www.youtube.com/watch?v=dazn0llUU9M
