Why cant Subaru use chains?
As a seasoned auto service provider, I often encounter questions about vehicle maintenance and the specific needs of different car brands. One common inquiry is why Subaru vehicles are generally not compatible with tire chains. In this article, we will explore the reasons behind this limitation and what alternatives Subaru owners can consider for winter driving.
Understanding Subaru's Design
Subaru vehicles are known for their all-wheel-drive (AWD) systems, which provide excellent traction in various driving conditions. However, the design of these systems can create challenges when it comes to using tire chains.
Reasons Subaru Vehicles Can't Use Chains
- Limited Clearance: Many Subaru models have limited wheel well clearance, which can lead to interference between the chains and the vehicle's body or suspension components. This can cause damage to both the chains and the vehicle.
- AWD System Compatibility: Subaru's AWD systems are designed to work optimally with specific tire types and sizes. Using chains can disrupt the balance and functionality of these systems, potentially leading to performance issues.
- Manufacturer Recommendations: Subaru explicitly advises against the use of tire chains on many of their models. Instead, they recommend using winter tires that provide the necessary traction without the complications that chains can introduce.
Alternatives to Tire Chains
For Subaru owners looking to enhance their vehicle's winter performance, there are several alternatives to consider:
- Winter Tires: Investing in a good set of winter tires is one of the best ways to ensure safety and performance in snowy or icy conditions. These tires are designed to provide better grip and handling.
- Studded Tires: In regions with severe winter weather, studded tires can offer additional traction. However, it's essential to check local regulations regarding their use.
- Traction Aids: Products like tire socks or other traction devices can be used as alternatives to chains. These options are often easier to install and remove and are less likely to cause damage to the vehicle.
Conclusion
While Subaru vehicles are not typically compatible with tire chains due to design and performance considerations, there are effective alternatives available. By choosing the right winter tires or traction aids, Subaru owners can confidently navigate winter conditions while ensuring the longevity and performance of their vehicles.
Frequently Asked Questions
Are chains bad for your car?
Snow chains can damage your tires if they're not installed improperly. They can also cause some damage if they contact the road.
What year did Subaru switch to timing chains?
Commonly found on most Subaru vehicles built in the 1990s and early 2000s, the EJ family of engines all feature timing belts. But, in 2010, the new FB family of engines featured an all-new design including a timing chain.
Are Subarus safe in snow?
Subarus are known for being good winter driving vehicles; the Forester, Outback, WRX, Ascent, and Crosstrek all receiving 7/10 or 8/10 rankings for winter driving. With all models possessing substantial ground clearance, Subarus are great for handling a road covered in snow.
What cars can you not put chains on?
Requirement 2 (R-2): Chains are required on all vehicles except four-wheel-drive vehicles under 6,500 pounds gross weight and equipped with snow tires on all four wheels. Chains for one set of drive wheels must be carried by four wheel-drive vehicles using snow tires.
What cars can drive in snow without chains?
In general, vehicles with 4WD and AWD don't need to chain up, as long as all wheels are in gear and they have approved traction tires with adequate tread. That includes studded tires and all-season, all-weather or snow tires (look for the M+S or mountain/snowflake symbol on the sidewall).
Can a Subaru drive in snow without chains?
Chains or traction devices are required on all vehicles except four-wheel/all-wheel drive vehicles with snow-tread tires on all four wheels. Note: four-wheel/all-wheel drive vehicles must carry traction devices in chain control areas. This is good news for every Subaru built since 1997 with the exception of the BRZ.
Why can't I put chains on my Subaru?
Subaru doesn't recommend chains because of two things: 1. It interferes with the Symmetrical AWD system. And 2. The actual clearance between the tires and the car may be too little to allow chains to even be fitted, without tearing up the wheel well.
Can you use chains on AWD Subaru?
The simple answer: no. Due to Subaru's Symmetrical All-Wheel Drive system, adding snow chains to your tires is not necessary, nor recommended. Many of Subaru's vehicle manuals explicitly state that snow chains are not recommended.
Is AWD or 4WD better in snow?
Typically, AWD is better for driving on snowy and icy roads because the driver doesn't have to make any changes or use guesswork. But 4WD is the better option if you're going to be driving in deep snow, rough back roads or very extreme winter weather conditions, such as a snowdrift or an icy hill.
Is it okay to put chains on AWD?
You need snow or winter tires or even snow chains when facing severe winter roads in any vehicle. That includes AWDs.
