Wiki says that

Most alloy wheels are manufactured using casting, but some are forged. Forged wheels are usually lighter, stronger, but much more expensive than cast wheels.

Does Toyota Camry 2015 -2017 (SE) use aluminum wheels? Are they produced using casting or are they forged? Are steel wheels safer than these alloy wheels? What type of wheels have more chances to be cracked?

  • Does Toyota Camry 2015 -2017 (SE) use aluminum wheels?

Depending on the option package, the Camry could come with either aluminum or steel wheels.

  • Are they produced using casting or are they forged?

Most OEM wheels are going to be castings and not forged. You have to get into the limited markets in order to find wheels of the forged varieties as OEM. Like Solar Mike tried to state, it all comes down to cost. A Camry is not a "top of the line" vehicle, so you most likely would not see it roll off the assembly line with a forged wheel. Even the Lexus (the up-brand Toyota) would most likely not see forged wheels.

  • Are steel wheels safer than these alloy wheels?

Safety of wheels is usually not an issue. Wheel failure is not usually a cause for accidents. It's usually something external which causes a wheel to fail, such as an accident or road hazard.

NOTE: There are safety reports which state 35% +/-11.4% of crashes are caused by tire/wheel failure, though they do not seperate out how much of each is the cause. Since tires are a wear item, it seems most likely (IMHO), the tire is by and large the greatest part of these failures which cause the crashes, either through the tire being worn out or improper inflation. This article also shows as Tires/Wheels being the #1 mechanical reason for crashes, but then only show tire blowouts and worn tires in the causal section. This article talks about the dangers of wheel separation from the vehicle as a larger issue than most would think. While a dislodged wheel flying from one vehicle to another is quite dangerous, this is caused not from wheel failure, but rather from the failure of wheel lugs/nuts (improper wheel installation), wheel bearing failure, and axle separation as the causes, not from failure of the wheel itself. Even split rims don't usually have issues once everything is seated properly during tire installation.

  • What type of wheels have more chances to be cracked?

A cast wheel will crack well before a steel wheel would. This is inherent in the design. The steel is much more flexible than is cast aluminum. But really, unless you are in an accident or there's a very severe road hazard (pothole or curb), there's really no worry for either to happen.

  • the report says 35% of all "Vehicle Related" crashes are wheel/tire related. "Vehicle Related" crashes are in turn only 2% of overall.. (same report table 1). – agentp Dec 10 '17 at 19:20
  • Thank you, high quality answer. LE has steel, SE alloy. I took SE because here in USA the roads are in good conditions. But in my native country Ukraine, i will prefere steel wheels and well known tiers, the roads are disgusting. photo – Parfen Dec 16 '17 at 6:46

Given your quote says forged are a lot more expensive then why would you think toyota would put them on a camry???

As are steels safer - Don’t really think they will make much difference - it’s road-holding suspension and tyre quality that make most difference.

I have just put winter tyres on alloys and the alloys replaced the steels I used last winter. Difference in road-holding in snow, ice - none that I can tell, but does it look prettier - oh yes!

One thing needs to be added to the two otherwise excellent answers. Steel wheels have thinner layer of steel than aluminium wheels do. This makes the wheel more flexible. When installing the wheel, there may be a grain of sand between the wheel and hub. When starting to drive, the grain of sand may break into smaller pieces. With steel wheels, the inherent flex means the preload of the nuts / bolts is not lost, at least not entirely in most cases. However, with aluminium wheels, the preload may be lost due to the rigidity of the wheel, and this means your wheel is at danger of separating from the car.

It is usually recommended to post-tighten nuts / bolts of an aluminium wheel after about 50 miles of driving. If this is not done, you have a small chance of having a safety hazard.

Other than this effect, there is no safety difference between steel and aluminium wheels. And also, it may not be an entirely bad idea to post-tighten nuts / bolts of a steel wheel as well.

Additionally, it might be a good idea to remove all dirt from between the hub and the wheel from the contact surfaces. Doing this makes it less likely that post-tightening is required.
