Its the additional weight of the wheel, plus the lack of traction. When you let a tyre down that has a decent sidewall, the tyre patch on the road lengthens and can almost double. With a low profile you, airing them down does very little. Link to comment https://www.fordxr6turbo.com/forum/topic/66809-drag-racing/#findComment-990077 Share on other sites More sharing options...
