Your 2016 Subaru Forester's Essential Tire Size
The standard tire size for most 2016 Subaru Forester models is 225/60R17. For models equipped with larger wheels, the size is often 225/55R18. Always verify your specific trim and original equipment.
- 225/60R17 is the most common tire size.
- 225/55R18 fits models with larger factory wheels.
- Check your driver's side doorjamb for the definitive placard.
- Match load index and speed rating to OEM specifications.
- Never deviate from recommended tire size without expert consultation.
Understanding the correct tire size for your 2016 Subaru Forester is fundamental to maintaining its performance, safety, and fuel efficiency. Using the wrong size can lead to inaccurate speedometer readings, compromised handling, and potential damage to your vehicle's drivetrain components, especially with AWD systems like Subaru's.
This specific SUV is designed with a particular tire profile in mind to optimize its all-wheel-drive capabilities and comfortable ride. The primary consideration involves finding a tire that fits your vehicle's wheels and meets the manufacturer's specifications for load capacity and speed rating.
Standard vs. Optional Wheel Sizes
The 2016 Forester typically came with either 17-inch or 18-inch wheels from the factory. The 17-inch wheels almost universally use the 225/60R17 tire size. The 18-inch wheels, usually found on higher trims like the Limited or Touring, require the 225/55R18 tire size. This difference accounts for variations in the tire's aspect ratio to maintain a similar overall tire diameter, which is crucial for the vehicle's systems.
The aspect ratio (the '60' in 225/60R17 or '55' in 225/55R18) indicates the tire's sidewall height as a percentage of its width. A lower aspect ratio means a shorter sidewall, which can provide sharper handling but potentially a firmer ride. Such precision is paramount for the vehicle's intended use.
Confirming your vehicle's exact tire size is a non-negotiable step before purchasing new tires.
Decoding Tire Size Numbers
Let's break down what those numbers mean for your 2016 Subaru Forester:
- 225: This is the tire's width in millimeters, measured from sidewall to sidewall.
- 60 (or 55): This is the aspect ratio, representing the tire's sidewall height as a percentage of its width. So, for 225/60R17, the sidewall height is 60% of 225mm.
- R: This signifies that the tire has a Radial construction, which is standard for virtually all modern passenger vehicles.
- 17 (or 18): This is the diameter of the wheel rim in inches that the tire is designed to fit.
Understanding this mechanism is fundamental to selecting compatible tires. It ensures the tire will mount correctly and the overall rolling diameter remains consistent with factory specifications.
Inspect the tire sidewall of your current tires for the most accurate size information, but always cross-reference with your vehicle's placard.
The primary consideration involves ensuring the new tires match these dimensions precisely. Any significant deviation can negatively impact your Forester's driving dynamics.
Why Tire Size Accuracy Matters for Your Forester
What happens when you fit tires that aren't the correct size on your 2016 Subaru Forester? The consequences can range from minor annoyances to serious safety concerns. For instance, using a tire with a significantly different overall diameter can throw off your speedometer and odometer readings, leading to incorrect speed indications and mileage tracking.
More critically, Subaru's Symmetrical All-Wheel Drive system relies on all four wheels rotating at very similar speeds. If you mismatch tire sizes, even subtly, it can cause the AWD system to work harder than intended, potentially leading to premature wear on the differentials and other drivetrain components. This is a critical point for Subaru owners.
Ensuring the correct tire size is paramount for maintaining the integrity and performance of your Subaru's sophisticated all-wheel-drive system.
Impact on Performance and Safety
Beyond drivetrain stress, incorrect tire sizes can affect your Forester's handling, braking, and stability. A tire with a much shorter sidewall might make steering feel more responsive but can also lead to a harsher ride and less absorption of road imperfections. Conversely, a tire with a taller sidewall might offer more comfort but could result in a less precise steering feel and increased body roll during cornering.
The load index and speed rating, often found near the tire size on the sidewall (e.g., 98H), are equally important. The load index indicates the maximum weight a tire can support, while the speed rating denotes the maximum speed at which the tire can safely operate. You must always select tires that meet or exceed the original equipment (OE) specifications for your 2016 Forester. This mechanism is critical for safety.
Never compromise on these ratings, as they directly impact your vehicle's ability to handle its intended load and perform safely at higher speeds.
When selecting replacements, treat the OE specification as the baseline. While slight variations in tire diameter (typically no more than 3%) might be tolerable, deviating further requires careful calculation and consideration of how it affects the vehicle's center of gravity and electronic systems.
Finding and Verifying Your Forester's Tire Size
Locating the definitive tire size information for your 2016 Subaru Forester is straightforward if you know where to look. The most reliable source is the vehicle's manufacturer-issued placard. This sticker is typically found on the driver's side doorjamb or inside the fuel filler door.
This placard lists the original equipment tire size, recommended tire pressure, and often the wheel size for your specific vehicle configuration. It's the manufacturer's direct recommendation and should be your primary reference point when shopping for new tires.
Where to Look for Tire Size Details
Beyond the doorjamb placard, you can also find the recommended tire size in your Subaru Forester's owner's manual. If you've lost the manual or the placard is unreadable, searching online using your vehicle's exact year, make, model, and trim level can yield accurate results from reputable automotive sites. For example, searching for the '2016 Subaru Forester 2.5i Premium tire size' will provide the specific information for that trim.
When you find a tire you're interested in, ensure the size printed on the tire matches what's on the placard or in your manual. For the 2016 Forester, this means looking for '225/60R17' or '225/55R18' as the core size, along with compatible load index and speed ratings.
Consult a professional tire dealer or your Subaru dealership if you have any doubts about the correct tire size or if you are considering an upgrade to a non-standard size.
It is imperative to acknowledge the importance of correct sizing for optimal vehicle operation. This detail ensures your Forester performs as intended.
Checking Tire Tread and Condition
While verifying your tire size, take a moment to inspect the condition of your current tires. Check for uneven wear patterns, which could indicate alignment or inflation issues. Also, examine the tread depth. Most jurisdictions require a minimum tread depth (often 2/32nds of an inch), but performance and safety degrade significantly long before that point. A tread depth of 4/32nds or more is generally recommended for good grip, especially in wet conditions.
Regularly checking your tire size, condition, and pressure is a vital part of vehicle maintenance.
The primary consideration involves selecting tires that not only fit correctly but also offer the appropriate performance characteristics for your driving needs and local climate.
