一、换轮胎的前言起因
从疫情前看到今年，各种变故改变方案，总算在今年中如愿以偿入手了一台很便宜的沃尔沃v40cc，车子刚到手时，第一次加满油，回去路上觉得底盘还算扎实，刚好前面有个急转弯，40km/h的速度入弯就懒得踩刹车，轻踩油门维持速度，车身也没怎么侧倾，但是居然听到轮胎的尖叫声，居然有点打滑了[发呆][发呆][发呆]我的还是四驱的…回去认真一看，原配的轮胎居然是回力r32，一款以静音耐磨省油出名的轮胎，干湿地抓地能力往后排着找的…完全不能忍啊，必须换了，然后再一看轮毂居然是7j r17的，原配上的225的轮胎都有点紧张了…于是就动了轮胎轮毂一起换的念头了
二、原厂轮毂升级方案
当初买车的时候就一直想着买cc顶配智尊版，顶配那个r18的轮毂可是稀罕的很，决定就换那个，闲鱼找了一圈，居然没有，没有人卖[流泪][流泪]
于是继续看v40的原厂轮毂，然后又发现那个低风阻的挺漂亮的，但是最便宜的拆车货都要2500[糗大了][糗大了][糗大了]，人穷志短，我忍…
三、另谋出路在领克里找出路
然后各大论坛转一圈，看到有大佬上捷豹xe的轮毂，而且看起来还很漂亮，顿时觉得思路大开，买不起沃尔沃的拆车货，可以考虑别的牌子拆车轮毂嘛，结果发现奇葩的沃尔沃居然跟大部分厂家不通用，只有领克跟捷豹的有参数一样的轮毂…然后闲鱼居然好像知道我想啥一样的，就给我推送领克03的轮毂，我靠，基本全新的03冠军版7.5j 18r轮毂居然只要300一个，参数完美匹配，而且还挺漂亮的，还有人卖一对五百自提~
怂恿了一车友买了，确实挺搭配，红色车身上这个轮毂真的很帅，他用的领克原厂轮胎225/45/18规格的，其实比较合适我的cc，他应该上个235/40/18才更帅更合适
在闲鱼上一通聊，找到一个隔壁城市的，价钱不错，有点打算下手了，结果卖家非要自提，我这里当时又有疫情，不方便出市，只能放着…
这时闲鱼又给我推送一对03+的18寸锻造轮毂居然只要550，轮毂大佬说必须上锻造啊，不然你换了有啥意义，必须买了！
跟卖家一聊，很是聊得来正准备下单，卖家发了轮毂参数来：8j r18et 57，et57这是个什么奇葩，怎么会有这么大的et值，再一查，cc的轮毂et居然是50，而不是普通v40的52.5[流泪]，大超更换轮毂et偏差不超过5要求，用工具算了下，足足内凹了20mm而且一般et最好减小，这样才好看…顿时觉得人生都无乐趣了…
03+轮毂与原车轮毂参数对比图
只好放弃03+的轮毂，只能考虑03了，安慰自己03的更漂亮…研究怎么把隔壁城市的那套一千块的03轮毂弄回来时，知乎上的轮毂大佬突然又给了个方案，你可以上法兰盘啊，加个10mm的法兰盘…于是马上回去问那对03+轮毂，结果人家居然卖了…然后再问做法兰盘的，居然说15mm起…闲鱼翻了一圈，03+轮毂便宜的都是磕碰很严重，不像03的到处都是几千公里拆车的，顿时又失去了动力，然后隔壁市那套03的轮毂卖家已经找到本地买家自提了…
四、突发奇想之s80轮毂方案
继续闲鱼闲逛，居然看到本地一s80大佬在处理他抛光过的s80轮毂，一套一千块，加五百附送一套半新的245/40/r17轮胎，真便宜啊，又帅气，卖家又好说话，还是c30玩家，直接约好打算去面试了
这时候知乎的轮毂大佬回复了，你想啥呢，8.5j轮毂配245轮胎，就算不考虑油耗，你那小车车塞的进去嘛，好像确实如此…只能跟本地大佬致歉[流泪]
五、峰回路转之捷豹xe轮毂
这时，论坛大佬说要甩卖他的捷豹轮毂+轮胎，嫌弃轮胎性能不够好，一套大降价，2000多甩卖，…漂亮而且性价比不错，最关键参数完美符合，et46，最完美了，整套也省事呀[色][色]，就这了，大佬说他国庆节后回来要换rd3轮毂，刚好等过了节发钱就找大佬下单！
六、美女当头之一时冲动买了03+轮毂
第二天习惯性打开闲鱼刷刷看，突然首页刷出来一套整套03+的18寸锻造轮毂，价钱便宜，没有大磕碰，赶紧聊上，居然又是隔壁城市，卖家一发语音居然还是美女，必须买了啊，美女当头，价也不砍了，秒下单，怎么安装费事情也以后再想办法了美女也给力第二天一早就发物流，然后就到了
七、失败的安装经历
本来计划国庆节假期大干一场的，结果刚好假期我们这里有疫情，开始不方便出门，后面直接都去做志愿者了…刚好先慢慢研究，先是法兰盘商家说法兰盘最薄都得15mm厚，纠结了好久，好不容易下定决心定做法兰盘时，发现了一个更严峻的问题，我的车不是螺母型的，螺杆是在刹车盘上，如果轮毂上对应位置没有孔洞就必须切原车螺杆，这就大工程量了…如果不用带中心孔台阶的法兰盘，直接用垫片，一个是受力变差很多，二是有一定概率会抖动…
原车螺杆形式
法兰盘是这样的
顺便放张安装示意图
从图片可以看到，我的螺杆长度远不止15毫米，肯定会凸出法兰盘一大截…
有些铸造轮毂会在这个位置镂空减重…刚好可以把长出来的螺杆放进去…
偏偏我买的03+轮毂是锻造的，这个位置是平的
完全无法可想，上法兰盘的思路基本走不通，除非以后不打算换回原车规格的轮毂…
实在还是不甘心，于是决定实践出真知，自己动手装上去看情况
找了个风和日丽的上午把轮毂洗干净，其实也不算丑啊
翻出随车工具开干
装上去的效果还不赖
但是感觉离避震实在有点太近了，有点不妙…
左右打死方向再看看情况
感觉这离轮拱距离实在太近了，上225/45/18的轮胎都悬啊…更不用说上235的了…
看来真的与03+轮毂无缘啊
八、历尽波折最后还是捷豹xe的轮毂修成正果
03+的轮毂彻底放弃后，实在不想折腾了，于是跟论坛大佬约定好要他的捷豹整套轮毂轮胎，03+轮毂放在闲鱼上挂着，还好这套轮毂比较好卖，几天都好多人来要了，亏点运费很快就处理了了~
然后开始安心等轮毂，结果居然波折不断…
先是因为疫情，卖家在工作地回不了老家，等了半个月总算回了老家，结果他放rd轮毂的房子隔壁有确诊，回了必定出不来，只能又等三天，好不容易卖家能换下轮毂了
发现快递运费实在太贵了，卖家问我知不知道便宜点的物流方式，想起以前闲鱼有物流打折的商家，于是买了个六五折的德邦物流，折下来运费不到150，好像还可以接受，结果里面有个天坑，物流那边说我们买了保险，必须打包装，账单一出来，包装费78…而且包装费保险费不能打折…算下来比发顺丰还贵…
最坑的是这高达78的包装费就是包了一层气泡纸跟蛇皮袋…等于没有保护…
然后等了三天后收到轮毂真的磕出了伤痕…
充新的轮毂变成了九新了
不过已经折腾了那么久，已经心急如焚了，懒得再去跟德邦吵架了，赶紧换上
好像红色豹子头搭配红色车身也不算丑
出去开了一圈回来，发现确实不容易打滑了，但是更吵更颠了

农滢俊4389汽车轮胎尺寸越大越耗油吗? -
闾仲怨19583544142 ______ 一般来说,同一款车型,由于轮拱空间是已经固定了的,如果轮毂尺寸越大,那么相应配套的轮胎扁平率就要越低轮胎的扁平率越低,车辆在拐弯时因胎肚软产生变形而出现的滑移角度就越低,车辆的指向准确性就越高、反应越快,而且从路面传达给驾驶者的讯息越丰富,操控感更加直接. 同时轮毂尺寸越大,就能够容纳更大直径的刹车碟盘和制动卡钳,刹车力也就更强. 但是轮毂尺寸越大,也自然会有重量增加,加速减弱,增加油耗,悬挂反应慢和影响行车舒适性等缺点.
农滢俊438917寸轮毂改19寸轮毂是废油还是省油 -
闾仲怨19583544142 ______ 当然是费油,改了之后汽车离地间隙增大,一般来说19寸比17寸的要宽,与地面摩擦力会增大,当然最好不改,因为汽车出厂都是匹配合理的,改了之后会出现一些次生小问题,特别是动力偏小的车.
农滢俊4389省油车排行指标中,15万左右最省油的家用车有哪些? -
闾仲怨19583544142 ______ 论省油的车子,日本车绝对No.1!同级车里面,日本车比国产车100KM省大概2-3升油,重量轻200KG左右.当然,4S店也永远不会告诉你,论推重比,小日本的车子会掉渣!另外驾驶习惯、路况、调教对油耗也有很大影响.比如 市区开车小日本的车子速度又快又省油,小轮毂比大轮毂省油;高速上大轮毂比小轮毂省油,档位越高越省油.车重耗的油相比于安全,个人觉得安全最重要!轩逸、锋范、卡罗拉神马的....
农滢俊4389汽车加大轮圈会比原来速度快省油吗 -
闾仲怨19583544142 ______ 关键是看你的轮胎宽度是否改变, 如果轮胎宽度变宽了,当然是更费油,加速更慢,但是刹车性能会更好,抓地性也会变好. 如果是变窄了,会相对省油一些,加速动力也会变好一点,但是刹车性能会下降,车的抓地性能也会变差. 轮毂的大...
农滢俊4389轮毂越大是不是耗油越高? -
闾仲怨19583544142 ______ 相反,你是骑小轮自行车比较吃力还是大的凤凰单车比较吃力?然后与轮胎有关的就是,轮胎宽度了,越宽的论坛油耗就更高一点.
农滢俊4389汽车轮毂尺寸越大越好还是越小越好 -
闾仲怨19583544142 ______ 任何汽车,在汽车登记证书里,已经写明了原厂轮胎的规格.那在这个规格基础上,增大轮毂尺寸,势必就要用到扁平比更低的轮胎.但这容易导致经过坑坑洼洼路面的时候轮胎鼓包或者损伤.因此要参考自己日常行驶的路面情况来决定.
农滢俊4389同样直径的汽车轮胎,宽面的省油,还是窄面省油
闾仲怨19583544142 ______ 窄面的省油!过宽的轮胎会与地面行成过大的接触面积,车身、轮胎与地面之间的阻力也就越大!更换大英寸的轮毂、轮胎,有一定的提升抓地力的作用对于车辆的操控性,安全性有点好处!但是节油是不可能的!当然太窄的轮胎也是不好地!
农滢俊4389轮毂越大越耗油? -
闾仲怨19583544142 ______ 轮毂的大小是根据车的来决定的 不是越大越好也不是越小越好 也要看材质进行对比,具体的可以去咨询一下创铭轮毂,专业的!
农滢俊4389轮胎大了省油还是小了省油 -
闾仲怨19583544142 ______ 理论上说,轮胎还是大了省油.
农滢俊4389星瑞大轮圈好还是小轮圈好
闾仲怨19583544142 ______ 星瑞大轮圈好很多在买车的时候都喜欢大轮毂,因为大轮毂一看就是高配车型,看起来大气,很多车企也会刻意用轮毂来区分高低配车型,甚至有的车主会在买完车之后,把轮毂进行改造,换上一个更大的轮毂,大轮毂看起来确实帅气运动,但是很多改了大轮毂的车主,往往会后悔,因为大轮毂的缺点实在是太多了.
