该换雪胎了吧?

不冷换啥？

缺心眼。

村长别激动, 考个小问题, RIM是合金的好,还是钢的好?

冬季用钢的。

网上有得是关于两种轮毂利弊的比较。

刚换来的

钢，容易生锈，所以价格低

Alloy vs. Steel Wheels

Updated September 25, 2018

Alloys or steels; what's best for you? Both types have advantages and disadvantages for different types of driving; but, in general, if you want beauty and performance you want alloy, and if you want tough, inexpensive, ugly workhorses, you want steels.


Alloy Wheels

Alloy wheels are now standard on most cars because they offer both cosmetic and performance advantages. Unlike steel wheels, aluminum alloy can be cast and worked in many different designs, giving cars a much more individual look, and offering owners the chance to customize even more. The aluminum/nickel alloy is much lighter than steel and makes for more agile performance and better acceleration. A car with alloys on is generally much more fun to drive.

Alloys do tend to bend easier than steels under road impacts and have a tendency to crack if bent too far. The degree to which an alloy wheel is pliable or brittle depends greatly on how much nickel is added to the aluminum to make the alloy – more nickel adds weight and tends to make the alloy more brittle, less means a lighter wheel that is softer and tends to bend more easily. Construction methods such as casting or pressure forging also have an effect on the alloy's strength.

Alloy wheels can be polished, painted, machined or chromed; different finishes should be cared for in different ways. They are also vulnerable to a range of cosmetic damage such as curb scrapes, saltwater corrosion, and acid cleaners.

Steel Wheels

The weight of wheels, tires, brakes, and rotors is specifically called “unsprung weight” because it is not being cushioned by the suspension springs. Unsprung weight has much more effect on how the car handles than an equivalent amount of weight above the springs, such that even a small change in weight can have large effects.

Steel wheels are heavier than aluminum, so when you put steel wheels on a car that has had alloy wheels, you tend to find that the extra weight dampens acceleration and agility, lowers the car's center of gravity and in general makes it drive more like a tank. Obviously, this can be undesirable for summer performance applications, but in the winter the effect can be a significant physical and psychological advantage. Heavier wheels will make tires bite the snow harder, and when driving in snow, having a car with dampened acceleration and agility, an artificially low center of gravity and a sense of solidity and heaviness can be a very good thing.

Steel wheels are significantly stronger than alloy wheels. It takes a great force to bend steel wheels, and it is almost impossible to crack them. Given their usual utilitarian look, the purely cosmetic damage is not generally a major issue.

There are wheel covers that you can put on steels to make them look like alloy wheels; they often come on steels sold as OEM choices and can be found online as well. Wheel covers are fragile, look kind of cheesy, and are most often held on by a spring steel friction grip that has a distressing tendency to come off at inconvenient times and roll away.

Steels are generally only made in 16” sizes or less. There are a very few 17” steels out there, but not a single 18” steel that I know of. I would imagine that an 18” steel would be ridiculously heavy. Consequently, putting on steels will often involve downsizing. Some high-performance cars will not accept downsized wheels because of oversized brake calipers or other suspension issues.

Steels are also usually 75-80% less expensive than alloy wheels, making them great for a second set, and inexpensive to replace if badly damaged.

Thus for many reasons alloys are the only choice when high performance and/or looks are the qualities you need. Steels are generally better for those no-nonsense daily drivers, or for any cars that don't have to look pretty or do fancy maneuvers because they work for a living. They are especially ideal, however, for that extra set of winter wheels.

谢谢，听说钢RIM容易锈，有这事儿吗？

是啊。几年就生锈了。但是一个原厂alloy rim 能买2-3套铁轮毂啊。这还是16-17寸的普通小车alloy rim。
aftermarket的alloy rim也要近两百一个。太便宜的不安全。
steel rim比较软，磕一下会变形。alloy rim比较脆，磕一下就掉一块甚至断裂。
steel rim最大缺陷就是丑，至于重量，那个根本不是优势。簧下一磅，簧上十磅。车重了会增加油耗，惯性和降低灵活性。
如果是truck，suv的话，steel rim也有比较好看的。

Canadian tire 的轮胎比Cosco 平宜。早两天去Cosco看每个轮胎139元，幸好当日不可能帮我们换，叫我们第二天七点去等。回家后叫儿子上网查一查，加拿大轮胎同样的牌子每个才102.49元。

Alloy 有人说冬天盐会腐蚀，容易漏气。很多Alloy标识的是winter，但不知道只是低温还是能抗盐腐蚀。

 

[ccc]

你说的正相反吧.

STEEL的RIMS容易生锈.

合金的一个长处就是防腐蚀.

你看到的是表面现象。

如果车配两套轮毂，冬季我一定用钢轮毂。

换上冬季胎了!

Let it snow, let it snow.

在哪家换的？COSTCO 说是得早上6点去排队。

我的车是两套轮子，我是自己换上去的。
