问题:“What are the benefits and trade-offs for staggered tire configuration? For normal vehicles and performance vehicles?”
ChatGPT回答:
Staggered tire configurations offer several benefits and trade-offs, both for normal vehicles and performance vehicles:
Benefits:
Improved traction: Staggered tire setups often provide better traction, particularly in performance vehicles where the rear wheels are wider. This is especially advantageous during acceleration, cornering, and braking.
Enhanced handling: The wider rear tires in a staggered setup can improve handling characteristics, such as stability and grip during cornering. This can result in better overall control and confidence, especially in high-performance driving situations.
Balanced performance: Staggered tire configurations allow for a balance between front and rear grip, optimizing the distribution of power in performance vehicles. This balance can contribute to a more predictable and enjoyable driving experience.
Aesthetic appeal: Many enthusiasts appreciate the visual appeal of staggered tire setups, as they can give the vehicle a more aggressive and sporty stance.
Trade-offs:
Cost: Staggered tire configurations often require purchasing different sizes of tires for the front and rear, which can be more expensive than buying a set of identical tires. Additionally, high-performance tires tend to have shorter lifespans and may need to be replaced more frequently.
Compromised rotation: With different tire sizes front and rear, tire rotation becomes more complicated. This can lead to uneven tire wear over time, requiring more frequent tire replacements.
Reduced versatility: Staggered setups may not be suitable for all driving conditions or vehicles. For example, in inclement weather or off-road situations, the wider rear tires could result in reduced traction and stability.
Potential understeer or oversteer: Improperly matched tire sizes or inadequate suspension tuning can lead to handling imbalances such as understeer (front tires losing grip) or oversteer (rear tires losing grip), affecting the vehicle's stability and control.
While staggered tire configurations can offer significant performance benefits in the right circumstances, they also come with certain drawbacks that drivers should consider based on their driving needs and preferences.
以前没注意到,tesla model 3/y performance 都是 staggered tire configuration,前后胎尺寸不同。staggered tire configuration 有什么不利的问题?比如磨损厉害?其它还有什么需要注意的?
staggered tire configuration 换胎时就没必要同时4个轮胎都换了?rotation 也只能左右换,不能前后换?
Porsche更明显,理由是驱动轮要有更大的与路面接触面以增加摩擦力。rotation 只能左右对换,换胎用不着同时四个换。
10几年前我们这里当地的Dealer,打折卖一辆Chrysler Crossfire Roadster新车。 要价3万。
可惜还是没有闲钱。玩不起。据说那车那时换一套4个胎就得化6000多。
这车其实是一辆奔驰小跑车。制造工厂是一家独立的德国Boutique的汽车设计制造厂Karmann。奔驰, VW, BMW也会委托他们造那种小型号的车(或者主流车的某个Variation)。
换句话说,前后胎尺寸相同 vs 前后胎尺寸不同,主要优缺点是什么?

越野湿地当然4驱好点,performance car追求的是理想路面上的能力。
一个是纯后驱,认为这更纯,比如法拉利、阿斯顿马丁。另一个是以具体测试数据最优化为目标,比如纽伯格林赛道开一圈的耗时,这点出发往往是四驱最好,比如保时捷、兰博基尼。
纯后驱的车,哪怕用了更宽的后轮,加上launch control系统,也会发生不能把全部引擎扭力放到地面上的现象,所以加速一定是比不过四驱车的。过弯道时后驱车在操控性上有一点点优势,但往往也比不过四驱车可以更早大力轰油门靠前轮帮助从弯道上拉出来。
不过,这种高性能四驱车都是往后轮传送扭力比例特别高的,一般都是70%以上。加上加速时重心后移,即使四驱也是后轮更宽的。
比较有意思的是这一代的911,后轮不仅宽,而且直径比前轮大一寸。后驱四驱版本都一样。
Range Rover Sport SV 算是真正越野四驱车吧?那是专设了低速档位,有泥沙、冰雪、爬行下山模式的四驱系统。前轮宽285,后轮宽305。
专门为越野设计的911 Dakar,你不见得对保时捷说不吧?前轮245 R19,后轮290 R20。
无独有偶,同为大众门下的Lamborghini也出了Huracan Sterrato,专门越野版的车,当然也是前后轮大小不同。
前中后差速并可以机械鎻定,那些靠刹车及电子离合器或液态连结器的全驱车,会有系统过热的危险,没人会真的拿去越野,而且Sterrato那広低的车头,只要一个小坑,车头就得贴地,可能要靠拖车才能拉出来,你大概从来没越野过,才会有这样的发言
全世界邀请专业车评人去沙漠里试车。你可以查查他们汇报的,能不能越野。这叫技术进步。反观丰田,更新个陆巡都不敢加个600马力V8TT的。别以为只有肉肉的加速才可以越野。

你说“ 开Lamborghini去越野?是不是在搞笑",我用LM证明你这句话也是错的。
