It\u2019s been two and a half years since I started this Porsche blog. I\u2019ve kept writing daily, and before I knew it, I\u2019ve published over 700 articles.<\/strong> Wow, that\u2019s a lot of writing. Recently, even articles I wrote a long time ago or had forgotten about have been getting a lot of views, making me often think again, \u201cOh right, that\u2019s what Porsche is all about<\/strong>.\u201d<\/p>\n So today, I want to revisit some of the most popular articles I\u2019ve written in the past about things you should know about Porsche<\/strong>.<\/p>\n First, this is especially relevant right now. On cold winter mornings, when turning the steering wheel slowly at low speed, you might hear a grinding, crunching noise from the tires. When I first experienced this \u201cgrinding noise,\u201d<\/p>\n I panicked, wondering if I had run over something or if I was driving wrong!<\/p>\n Back then, my car knowledge was even more limited than now, so I just thought, \u201cNoise from the tires = something\u2019s broken<\/strong>.\u201d When I asked my husband, I learned this grinding noise is not a malfunction.<\/p>\n Porsche uses a \u201cparallel steering geometry\u201d instead of the commonly used \u201cAckermann steering geometry\u201d<\/strong> in its steering system. Because of this, on cold winter days at low speeds, you often hear grinding or crunching noises from the tires.<\/p>\n Parallel steering geometry is a steering mechanism designed specifically for sports cars and race cars to enable smoother cornering at medium to high speeds. So, hearing this noise means \u201cPorsche is a true sports car\u201d<\/strong>.<\/p>\n By the way, my husband said,<\/p>\n \u201cAMGs can make this noise sometimes too. Also, depending on the tires you use, this grinding noise can be reduced.\u201d<\/p>\n (For a detailed explanation, see the article below.)<\/span><\/p>\nTire Grinding Noise on Cold Winter Mornings<\/h4>\n
