By 2008, Subaru had firmly established its reputation for all-weather confidence, car-based utility, and wagon-to-crossover versatility. The 2008 Subaru Trucks range reflects that character with the compact Forester and the larger, more road-focused Tribeca, each using modern radial tire sizing that matches its role and stance. Across these two models, three tire sizes appear, and they are model-specific rather than shared across the whole year and make. That means the first step with 2008 Subaru Trucks is confirming whether you have a Forester or a Tribeca, then verifying which wheel diameter your vehicle uses before narrowing down the right tire.
Which Tire Size Is Right for Your 2008 Subaru Trucks
Three tire sizes are used across 2008 Subaru Trucks vehicles, and they vary by model rather than being shared across the full range. The real decision starts with confirming the correct model and wheel diameter, since the Forester uses 16-inch or 17-inch fitments while the Tribeca uses an 18-inch fitment. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 2008|Fit(s): Forester|Construction: Radial|Rim: 16-in rim
A 215/60R16 is a radial metric tire with a 215-millimeter section width, a 60-series aspect ratio, and a 16-inch rim diameter. This size is specific to certain 2008 Subaru Trucks Forester applications, and product details such as brand, sidewall style, tube status, and speed rating should be confirmed on the exact tire selected. As a modern radial fitment, it suits owners who want the tire size that matches their Forester's original wheel diameter and intended road-going character.
Year(s): 2008|Fit(s): Forester|Construction: Radial|Rim: 17 in
A 215/55R17 is a radial metric tire with a 215-millimeter section width, a 55-series aspect ratio, and a 17-inch rim diameter. This size is specific to 2008 Subaru Trucks Forester models equipped with 17-inch wheels, and it is available from BFGoodrich in Blackwall form with W-rated products carrying 112 mph speed capability. Owners choosing this size should confirm they have the 17-inch Forester wheel package, then select the product that best matches how the vehicle will be driven.
Year(s): 2008|Fit(s): Tribeca|Construction: Radial|Rim: 18-in rim
A 255/55R18 is a radial metric tire with a 255-millimeter section width, a 55-series aspect ratio, and an 18-inch rim diameter. This size is specific to the 2008 Subaru Trucks Tribeca rather than universal across the year and make, so buyers should verify the larger 18-inch wheel fitment before moving forward. Its wider, larger-diameter radial format aligns with the Tribeca's more substantial crossover layout and road-oriented use.
Two models are covered for 2008 Subaru Trucks. Tire size varies by model, and even within the Forester range the correct fitment depends on whether the vehicle carries 16-inch or 17-inch wheels, so identifying the exact model is the key first step. Select a model below to narrow the fitment history and tire choices for your vehicle.
2008 Subaru Trucks Forester
The 2008 Forester bridged the gap between compact wagon and small SUV, which is a big part of why it remains popular with drivers who want practical utility without the size of a full crossover. It uses either a 16-inch or 17-inch tire fitment depending on configuration, so wheel diameter matters just as much as model identification when choosing tires.
The 2008 Tribeca was Subaru's larger, more upscale crossover, aimed at buyers who wanted all-wheel-drive confidence in a roomier family-oriented package. Its tire fitment mounts on an 18-inch wheel, setting it apart from the Forester and making wheel size confirmation especially important before choosing a replacement tire.
Two products are available across one tire size for 2008 Subaru Trucks vehicles. The 215/55R17 fitment includes two BFGoodrich radial Blackwall options, so confirm your Forester uses the 17-inch size before choosing between them.
These answers cover how 2008 Subaru Trucks tire sizes differ between Forester and Tribeca models, what the metric radial codes mean, how the available 17-inch products compare, and what to check for long-term collector or low-mileage use.
Size Basics & Fitment
What tire sizes fit 2008 Subaru Trucks vehicles?
Three tire sizes fit 2008 Subaru Trucks vehicles, and they are split by model. The Forester uses 215/60R16 or 215/55R17, while the Tribeca uses 255/55R18. Those sizes do not share the same rim diameter, so a 16-inch, 17-inch, or 18-inch wheel must match the tire exactly. Rim-width guidance is available for the 215/55R17 size at 6.0 to 7.5 inches, depending on the specific BFGoodrich product.
The practical takeaway is that year and make alone are not enough for 2008 Subaru Trucks. You need to identify the model first, then confirm the actual wheel diameter on the vehicle before choosing a tire. That is especially important with the Forester, since the same model line can use either 16-inch or 17-inch tires. If the vehicle has changed hands or has aftermarket wheels, checking the sidewall of the current tire and measuring the wheel diameter is the safest starting point.
What does 215/55R17 mean on a 2008 Subaru Trucks tire?
On a 2008 Subaru Trucks Forester, 215/55R17 is a modern metric radial size. The 215 is the nominal section width in millimeters, 55 is the aspect ratio, R means radial construction, and 17 is the wheel diameter in inches. In the available 17-inch Forester products, this size appears as 215/55ZR17 with a W speed rating, which indicates 112 mph capability.
That decoding helps you avoid two common mistakes: treating 215/55R17 as interchangeable with a different 215-width tire, or assuming any 17-inch tire with a similar overall look will fit correctly. The width, sidewall proportion, and wheel diameter all matter together. For a 2008 Subaru Trucks Forester, the 215/55R17 size should only be chosen when the vehicle actually has the 17-inch wheel package, and the final product choice should still be checked for rim-width compatibility and intended use.
Do all 2008 Subaru Trucks models use the same tire size?
No, 2008 Subaru Trucks models do not all use the same tire size. The Forester uses either 215/60R16 or 215/55R17 depending on configuration, while the Tribeca uses 255/55R18. That means there is no single year-wide replacement size shared across the full Subaru Trucks range for 2008.
For buyers, that changes the process from a simple year-make search to a model-and-wheel-diameter check. A Forester owner still needs to confirm whether the vehicle is on 16-inch or 17-inch wheels, and a Tribeca owner needs to stay with the 18-inch fitment unless the vehicle has been intentionally modified. When the model range uses different tire sizes this way, the sidewall marking on the current tire is one of the fastest ways to verify what belongs on your specific 2008 Subaru Trucks application.
Buying the Right Tire
What sidewall styles are available for 2008 Subaru Trucks tires?
Within the currently covered 2008 Subaru Trucks fitments, the available 215/55R17 Forester products use a Blackwall sidewall style. That suits the late-2000s Subaru look well, since these vehicles were designed around modern, understated radial tires rather than wide whitewalls or period-styled collector sidewalls. The overall appearance is clean and contemporary, which is appropriate for both everyday-driver and preserved original-condition examples.
Sidewall style matters most when you want the tire to match the character of the vehicle as closely as possible. On a 2008 Subaru Trucks application, Blackwall is the natural visual choice and avoids giving the vehicle a style cue from a much earlier era. If appearance is a priority, compare the sidewall branding and tread presentation of the exact tire you are considering, but keep the correct size and wheel diameter ahead of cosmetic details.
What brands make tires for 2008 Subaru Trucks vehicles?
BFGoodrich currently covers the 215/55R17 fitment used on certain 2008 Subaru Trucks Forester applications. The available products in that size are from the g-Force family, including COMP-2 A/S and g-Force Phenom T/A, both built as radial Blackwall tires. That gives Forester owners a clear brand path when they need a 17-inch replacement within this fitment group.
Brand matters less than matching the correct model, size, and wheel diameter, especially across a year-make range that includes multiple fitments. A 2008 Subaru Trucks buyer should first confirm whether the vehicle is a Forester or Tribeca, then verify the sidewall size before narrowing down brand preference. Once that is settled, the remaining choice comes down to the exact product's load rating, speed rating, and physical fit on the wheel rather than the badge on the sidewall alone.
What is the difference between BFGoodrich g-Force COMP-2 A/S and BFGoodrich g-Force Phenom T/A for the 2008 Subaru Trucks Forester?
Both BFGoodrich options for the 2008 Subaru Trucks Forester share the same 215/55ZR17 size, radial construction, Blackwall sidewall style, 17-inch rim diameter, and 6.0 to 7.5-inch rim-width compatibility. The clearest spec difference is load rating: the g-Force Phenom T/A carries a 98W service description and a maximum load of 1,653 pounds at 50 psi, while the COMP-2 A/S is marked 94W. Their weights are also very close, at 26 pounds for the COMP-2 A/S and 26.12 pounds for the Phenom T/A.
That means the decision is not about basic fitment, since both mount on the same wheel diameter and width range. Instead, the useful comparison is the exact service description and how closely you want the replacement to align with your driving priorities. A Forester owner choosing between them should verify the wheel size first, then compare the sidewall markings carefully so the final tire matches the vehicle's use and load expectations.
Fitting & Setup
What rim width do 2008 Subaru Trucks tires require?
For the 2008 Subaru Trucks Forester in 215/55R17, the supported rim-width range is 6.0 to 7.5 inches. That range is consistent across the available BFGoodrich options in that size and gives a useful checkpoint when replacing tires on original or equivalent wheels. The 17-inch rim diameter is fixed by the tire size, and the rim width needs to fall within that approved span for the tire to seat and carry its shape correctly.
Rim width matters because a tire can be the correct diameter yet still be a poor match for the wheel if the width is outside its approved range. Before mounting a new 215/55R17 on a 2008 Subaru Trucks Forester, confirm the wheel width rather than assuming every 17-inch wheel is the same. That becomes especially important when the vehicle has changed wheels at some point in its life, since aftermarket wheels may not match factory width even when the diameter looks correct.
Do 2008 Subaru Trucks tires require inner tubes?
The available 215/55R17 products for the 2008 Subaru Trucks Forester are modern radial tires without tube-type markings, which points to tubeless construction for that fitment. That matches normal late-model Subaru practice, since vehicles from this era were designed around tubeless radial tires and compatible wheels. A modern 2008 Subaru Trucks application would not ordinarily call for an inner tube unless a wheel condition issue or specialty setup specifically required one.
Tube decisions should still be tied to the exact tire and the condition of the wheel rather than made by habit. If a wheel has corrosion, damage, or a sealing problem, fixing the wheel is usually the right first move instead of adding a tube to work around it. When replacing tires on a 2008 Subaru Trucks vehicle, inspect the valve stems at the same time and make sure the wheel is appropriate for the tire's tubeless design before final installation.
Maintenance, Storage & Longevity
How should I store a 2008 Subaru Trucks when the tires are fitted?
A 2008 Subaru Trucks vehicle should be stored away from direct sunlight, standing moisture, and ozone sources such as electric motors, compressors, and battery chargers. Keep the tires properly inflated, roll the vehicle occasionally if possible, and avoid leaving one contact patch loaded in the same spot for months at a time. Radial tires generally tolerate static storage better than older bias-ply designs, but they still age from environment and time even when tread wear is minimal.
Good storage habits matter because many Foresters and Tribecas now live low-mileage lives, and age becomes a bigger issue than mileage. A clean, dry garage and periodic movement help preserve the casing, sidewalls, and overall ride quality. If the vehicle will sit through a long season, checking inflation every few weeks and keeping the tires off contaminated concrete or oily surfaces can do more for long-term tire health than simply covering the vehicle and forgetting about it.
How long do tires on a 2008 Subaru Trucks typically last?
On a 2008 Subaru Trucks vehicle, tire life should be judged by age and condition as much as by tread depth. A good rule is to begin close inspection around five to seven years of service and treat ten years as the outer edge for serious replacement consideration, even if the tires still look usable. The DOT date code on the sidewall is the key reference point for age, especially on a low-mileage collector or secondary-use Subaru.
That approach matters because many vehicles from this period accumulate far fewer miles than their original owners expected. A 2008 Subaru Trucks Forester or Tribeca can easily wear out its tires by time, heat cycles, and exposure long before the tread is gone. If the sidewalls are cracking, the rubber feels hardened, or the vehicle develops vibration and pressure-loss issues, age may be the real problem even when the tread still appears serviceable.
How often should tires on a 2008 Subaru Trucks be inspected?
Tires on a 2008 Subaru Trucks vehicle should be inspected before every drive and more carefully before any longer highway trip. Look for cracking, cuts, bulges, uneven wear, embedded objects, and any sign that the tire has been run low on pressure. Pressure retention should also be checked regularly, because slow leaks often show up before visible damage does on a lightly used vehicle.
Frequent inspection is especially important on a vehicle that spends long periods parked between outings. A Forester or Tribeca that looks fine in the garage can still develop age-related sidewall issues, a puncture discovered too late, or a valve-stem leak that leaves the tire underinflated by the time it reaches the road. Making tire inspection part of every pre-drive routine helps catch small problems early, when they are still easy to correct and less likely to spoil a trip.
Restoration & Authenticity
What tires were originally fitted to the 2008 Subaru Trucks Forester?
The 2008 Subaru Trucks Forester was built in the modern radial era, so radial construction is the correct original-type tire format for the vehicle. Within this model line, the Forester uses either 215/60R16 or 215/55R17 depending on wheel package, both of them metric radial sizes rather than older numeric or bias-ply formats. That means originality starts with confirming the correct wheel diameter and matching the tire size accordingly.
For a factory-faithful restoration or preservation effort, the goal is to stay with the correct radial size, proportion, and general sidewall character for the specific Forester configuration. Because wheel and tire packages could vary within the model line, the door-jamb placard, owner's literature, and marque-specific Subaru references are the best next checkpoints. That extra confirmation is worthwhile if the vehicle will be judged, preserved as an original example, or returned to a stock presentation.
Does correct tire fitment matter for showing a 2008 Subaru Trucks?
Correct tire fitment does matter when a 2008 Subaru Trucks vehicle is presented for judging or careful preservation. On a late-model collector vehicle, judges and knowledgeable enthusiasts often notice whether the tire size, construction type, wheel diameter, and sidewall presentation look appropriate to the model and era. A Forester wearing the wrong 16-inch or 17-inch equivalent, or a Tribeca on an obviously incorrect diameter, can look out of character even before anyone studies the details closely.
The standard for what counts as correct depends on the event. Some shows reward factory-faithful presentation, while others are more relaxed about modern replacement choices as long as the overall appearance remains appropriate. If originality matters, use the exact size family that belongs to the model and confirm the wheel package before installation. Subaru clubs and event rulebooks are the best resources when you want to match the expectations of a specific judging environment.
What is the difference between stock-style tire fitment and modified wheel fitment for 2008 Subaru Trucks?
A stock-style tire fitment for 2008 Subaru Trucks keeps the Forester or Tribeca on its correct model-specific diameter and tire size family, such as 215/60R16, 215/55R17, or 255/55R18. A modified wheel fitment changes that relationship by altering wheel diameter, width, or offset, which can affect the tire size needed to maintain overall clearance and driving manners. Even when the new setup looks close, it is no longer the same fitment standard the vehicle was designed around.
That distinction matters for both appearance and function. Owners preserving a clean original Forester or Tribeca usually benefit from staying with the stock-style size because it keeps the vehicle visually and mechanically in character. Modified setups can work, but they move the decision away from simple year-make-model replacement and into custom fitment territory. If the vehicle has aftermarket wheels, measure and verify everything carefully before assuming an original-equivalent tire size still applies.
Safety & Road Use
Are 2008 Subaru Trucks tires safe for highway driving?
Yes, the radial tire formats used on 2008 Subaru Trucks are suitable for normal highway use when the tires are the correct size, in sound condition, and inflated properly. The available 215/55ZR17 Forester products carry a W speed rating, which corresponds to 112 mph capability. On a vehicle like a 2008 Subaru, real-world road safety usually depends more on tire age, inflation, alignment, brakes, suspension condition, and overall maintenance than on reaching the limit of the speed symbol.
The main caution is to treat age and condition seriously, especially on low-mileage vehicles that may still wear old rubber. A fresh, properly fitted tire in the correct size is far more reassuring than an aged tire with good-looking tread. Before taking a 2008 Subaru Trucks Forester or Tribeca on sustained highway runs, inspect the sidewalls, confirm pressures cold, and make sure the tires match the wheel diameter and load demands of the vehicle.
What inflation pressure should I use for 2008 Subaru Trucks tires?
Inflation pressure for a 2008 Subaru Trucks vehicle should follow the factory vehicle placard or owner's manual first, because Subaru set those recommendations around the vehicle's weight distribution and handling balance. For the available 215/55ZR17 Forester fitment, one BFGoodrich g-Force Phenom T/A carries a maximum load of 1,653 pounds at 50 psi, but that figure is the tire's maximum rated load pressure, not a blanket operating pressure for every Forester.
That distinction is important because running every tire at its maximum sidewall pressure can compromise ride quality, contact patch shape, and wear pattern if the vehicle does not call for it. Use the vehicle's recommended cold pressure as the starting point, then make sure the tire chosen has enough load capacity for the application. If the placard is missing or the wheel-and-tire setup has been changed from stock, the safest next step is to verify both vehicle and tire guidance before setting pressures.
What should I check before taking a 2008 Subaru Trucks on a longer drive?
Before a longer drive in a 2008 Subaru Trucks vehicle, inspect each tire for cracking, cuts, bulges, punctures, uneven wear, and proper cold inflation pressure. Check the age of the tires, look over the valve stems, and make sure the spare is usable and properly inflated if the vehicle still carries one. Tire condition should be part of a broader pre-trip review that also includes brakes, fluids, lights, and suspension, especially on an older vehicle that may not be driven every day.
That routine is especially worthwhile on a Forester or Tribeca that has spent long periods parked or has recently returned to service. Tires can lose pressure gradually, develop age-related weakness, or reveal alignment issues only when the vehicle is driven at speed for an extended time. Catching those issues in the garage is far better than discovering them on the road. A few minutes spent checking the tires before departure can prevent vibration, poor handling, or a roadside problem later.
