The 2008 Subaru Outback sits in the era when Subaru had firmly established the Outback as a wagon-based all-weather daily driver with real utility, long-distance comfort, and a loyal enthusiast following. Buyers often keep these cars on the road because they balance practical use with a distinctive crossover-wagon identity. Tire fitment on the 2008 Subaru Outback is centered on two radial sizes, 225/55R17 and 225/60R16, and the correct choice depends first on the exact sub-model and wheel diameter. Available options range from straightforward blackwall performance-style radials to redline, whitewall, and stripe treatments, so appearance matters almost as much as fitment. That makes wheel verification and intended use the key starting points before choosing a replacement tire.
Which Tire Size Is Right for The 2008 Subaru Outback
The 2008 Subaru Outback uses two primary tire sizes, and the difference comes down to sub-model and wheel diameter. Both are radial metric sizes, but one fits 17-inch wheels and the other fits 16-inch wheels, so confirming the exact sub-model and the wheel currently on the car is the first step before comparing tire style, sidewall treatment, or brand.
Fit(s): 2.5i, 2.5i L.L. Bean Edition, 2.5i Limited, 2.5i Limited L.L. Bean Edition, R L.L. Bean Edition, and XT Limited
Construction: Radial|Rim: 17 in
225/55R17 is a metric radial size in which 225 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2008 Subaru Outback, this size serves the 17-inch wheel fitment used on several sub-models. Product choices in this size include blackwall performance-oriented BFGoodrich g-Force offerings as well as Silvertown Radial versions with wide whitewall and redline styling. It is the right place to focus if your Outback has 17-inch wheels and you want to balance everyday road use with a specific visual presentation.
225/60R16 is also a metric radial size, with the same 225-millimeter nominal width but a 60-series profile on a 16-inch wheel. For the 2008 Subaru Outback, this size belongs to the 16-inch wheel setup rather than the 17-inch applications, so wheel diameter must be confirmed before selection. Available tires in this size include Goodyear, BFGoodrich, and Travelstar products, with sidewall treatments such as raised yellow letter, redline, pin-white-stripe, wide whitewall, and narrow whitewall. This size is the proper starting point when the car retains its 16-inch wheel fitment and the goal is to match both function and appearance.
Sub-model fitment on the 2008 Subaru Outback is split between two tire sizes, so identifying the exact version matters before choosing a replacement. Most covered sub-models use the 17-inch setup, while the Base model uses the 16-inch size.

2008 Subaru Outback 2.5i
The 2008 Subaru Outback 2.5i uses the 225/55R17 radial fitment associated with the 17-inch wheel setup. Tire selection here is mostly about choosing the right radial style, whether that means a straightforward blackwall look or a more appearance-driven redline or whitewall treatment.
The 2008 Subaru Outback 2.5i L.L. Bean Edition uses the 225/55R17 radial size. That keeps the decision centered on 17-inch tire choices and makes it important to compare sidewall style, tire series, and wheel compatibility rather than searching across multiple primary sizes.
The 2008 Subaru Outback 2.5i Limited also uses 225/55R17 radial tires. With the size already defined, the next step is choosing among the available 17-inch radial options based on the appearance you want and the wheel dimensions actually on the car.
The 2008 Subaru Outback 2.5i Limited L.L. Bean Edition uses the same 225/55R17 radial fitment as the other 17-inch applications. That makes the main decision one of tire character and sidewall style rather than figuring out between different primary fitment sizes.
The 2008 Subaru Outback Base uses the 225/60R16 radial size tied to the 16-inch wheel setup. Buyers with this model should stay focused on 16-inch tire options and confirm the wheel remains original size before comparing raised-letter, stripe, or whitewall presentations.
The 2008 Subaru Outback R L.L. Bean Edition uses 225/55R17 radial tires. That points the selection process toward the 17-inch group, where the meaningful choice is between different radial series and sidewall treatments rather than a different primary fitment.
The 2008 Subaru Outback XT Limited uses the 225/55R17 radial size. Tire shopping for this sub-model starts with confirming the 17-inch wheel setup, then choosing the available radial style that best suits the car's use and overall look.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Best 2008 Subaru Outback Tires for Sale
Available 2008 Subaru Outback tires cover both primary sizes and include BFGoodrich, Goodyear, and Travelstar offerings. The main points of comparison are 16-inch versus 17-inch fitment, blackwall or lettered performance styles, and restoration-oriented redline, whitewall, and stripe sidewall treatments.
These 2008 Subaru Outback tire FAQs focus on the two correct sizes, the difference between 16-inch and 17-inch fitment, available sidewall and brand choices, and the checks worth making before putting a car back into regular road use.
Tire Size & Fitment
What tire size fits a 2008 Subaru Outback?
A 2008 Subaru Outback uses one of two radial tire sizes: 225/55R17 or 225/60R16. The 225/55R17 size applies to the 2.5i, 2.5i L.L. Bean Edition, 2.5i Limited, 2.5i Limited L.L. Bean Edition, R L.L. Bean Edition, and XT Limited, while the Base model uses 225/60R16.
The important next step is confirming the exact sub-model and checking the wheel diameter currently on the car. Many Outbacks remain stock, but wheel changes over time are common, and the correct tire choice depends on matching the tire size to the actual 16-inch or 17-inch wheel setup.
What size rim does a 2008 Subaru Outback use?
A 2008 Subaru Outback uses either a 17-inch rim or a 16-inch rim, depending on sub-model. The 225/55R17 tire size is matched to a 17-inch wheel, and the 225/60R16 tire size is matched to a 16-inch wheel.
Rim diameter is the first thing to verify before buying tires because a 16-inch tire cannot be mounted on a 17-inch wheel, and the reverse is also true. Once the wheel diameter is confirmed, compare the wheel width and the tire's approved rim-width range to narrow the choices further.
Do all 2008 Subaru Outback sub-models use the same tire size?
No, 2008 Subaru Outback sub-models do not all use the same tire size. Most of the covered sub-models use 225/55R17, while the 2008 Subaru Outback Base uses 225/60R16.
That difference matters because the two sizes are built for different wheel diameters, even though their overall dimensions are fairly close. A buyer should identify the exact sub-model, then confirm whether the car still has its original wheel setup before comparing tire series, sidewall appearance, or brand options.
Choosing the Right Tire
What should I consider when choosing a tire for a 2008 Subaru Outback?
Start with the correct primary size for the car: 225/55R17 for the 17-inch applications or 225/60R16 for the Base model's 16-inch setup. After size, the key comparisons are radial construction details, approved rim-width range, sidewall appearance, brand, tire series, and any load information that matters for the way the car is used.
A practical choice depends on whether the Outback is being kept as a regular driver, a clean period-style wagon, or something in between. Blackwall and performance-oriented options create a different look than redline, whitewall, stripe, or raised-letter tires, so fitment and appearance should be weighed together rather than separately.
What sidewall styles are available for 2008 Subaru Outback tires?
Available sidewall styles for the 2008 Subaru Outback include Blackwall, Redline, Wide Whitewall, Raised-Yellow-Letter, Pin-White-Stripe, and Narrow Whitewall, depending on tire size. The 17-inch 225/55R17 options are centered on blackwall, redline, and wide whitewall, while the 16-inch 225/60R16 range adds raised yellow letter and additional stripe and whitewall treatments.
That variety means the tire can change the personality of the car even when the size stays correct. A buyer trying to keep a clean, understated look may lean toward blackwall, while someone after a more custom or nostalgic presentation may focus on whitewall, redline, or lettered sidewalls in the appropriate size.
What brands offer tires for the 2008 Subaru Outback?
Tires for the 2008 Subaru Outback are available from BFGoodrich, Goodyear, and Travelstar across the two primary sizes. BFGoodrich appears in both 225/55R17 and 225/60R16, while Goodyear and Travelstar are available in the 225/60R16 size.
Brand is only one part of the decision, because the available products also differ by tire series, sidewall style, rim-width compatibility, weight, and in some cases load specification. Once the correct size is confirmed, compare the details that affect how the tire will look and how well it matches the wheel on the car.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Subaru Outback?
A period-style 2008 Subaru Outback starts with the correct original-size format for the car's wheel setup, which means 225/55R17 or 225/60R16 depending on sub-model. From there, the look can move in different directions, from plain blackwall radials to redline, whitewall, stripe, or raised-letter styles that give the car a more distinctive visual character.
The best appearance choice depends on whether the goal is a subtle late-2000s daily-driver look or a more customized presentation. When exact historical presentation matters, compare the car against photographs, dealer literature, marque references, or long-term ownership history before settling on a sidewall style simply because it is available.
How does tire construction affect the appearance of a restored 2008 Subaru Outback?
Tire construction is straightforward on a 2008 Subaru Outback because the primary fitments are radial. That keeps the visual difference less about bias-ply versus radial and more about how the sidewall is finished, whether in blackwall, redline, whitewall, stripe, or raised-letter form.
For a restoration-minded owner, that means the tire's side profile and sidewall treatment will shape the final presentation more than the construction label alone. Wheel diameter still matters just as much, since a 16-inch and 17-inch setup change the tire choice entirely even when the overall look of the car remains close.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Subaru Outback?
Yes, modifications can affect tire fitment on a 2008 Subaru Outback even when the tire size appears close to stock. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, lift changes, or body and fender modifications can all influence how a 225/55R17 or 225/60R16 tire sits and clears the vehicle.
That makes it important to inspect the actual setup rather than relying only on the model name. A car with non-original wheels should have its wheel diameter, width, and clearance checked at full steering lock and through suspension travel before a replacement tire is selected.
What should I inspect before driving a 2008 Subaru Outback on new tires?
Before driving a 2008 Subaru Outback on new tires, inspect the wheels for the correct diameter and condition, confirm the tires are inflated properly, and look over the suspension and steering for worn parts that could affect wear or handling. It also helps to make sure the old tires did not leave behind any clues of rubbing, uneven wear, or air-loss issues.
A short road check should include listening for rubbing, feeling for vibration, and rechecking pressure after the tires have settled in. On a vehicle that may have seen wheel swaps or years of mixed maintenance, those simple checks can catch fitment or condition problems before they become larger issues.
How should tires on a 2008 Subaru Outback be maintained?
Tires on a 2008 Subaru Outback should be checked regularly for pressure, tread wear, cuts, punctures, sidewall damage, and any signs of uneven wear that could point to alignment or suspension issues. Even on a car that is not driven often, age and storage conditions still matter, especially if it sits outside or spends long periods parked.
Routine maintenance is not only about preserving tread life but also about keeping the car dependable for real road use. Periodic inspections, attention to air loss, and storing the vehicle away from prolonged sunlight, heat, moisture, and ozone sources can help the tires stay in sound condition longer.
