更寬的輪胎會給你更多抓地力嗎？測試和解釋了不同的輪胎寬度

更寬的輪胎會給你更多抓地力嗎？合乎邏輯的答案是肯定的，輪胎越寬，與表面接觸的橡膠越多，但事實並非如此簡單。
隨著輪胎變寬，輪胎的佔地面積也會發生變化。雖然足跡越來越寬，但它也會變短，輪胎在外傾和負荷下的變化也會發生變化。
我沒有擔心更寬輪胎的理論，而是決定實際進行測試並讓結果說明一切。這是一個複雜的測試，經過近一年的規劃，以及Goodyear的大量幫助，由此產生的視頻應該告訴您關於裝配更寬輪胎的所有信息！

Do wider tyres give you more grip? Different tyre widths tested and explained

Do wider tyres give you more grip? The logical answer would be yes, the wider the tyre, the more rubber in contact with the surface, but it isn't that simple.
As a tyre gets wider, the footprint of the tyre changes. While the footprint does get wider, it also gets shorter, and how the tyre changes under camber and load is altered too.
Instead of worrying about the theory of wider tyres, I decided to actually do the test and let the results speak for themselves. It was a complicated test, and after nearly a years planning, and a large amount of help from Goodyear, the resulting video should tell you all you need to know about fitting wider tyres!
Below the video is all the technical data from the test. If you have any further questions once you've watched the video, please feel free to comment on YouTube and I will answer the best I can.
