2011 Subaru Trucks Tire Fitment Guide

2011 Subaru Trucks vehicles use three tire sizes across two models. The Forester uses 215/65R16 or 225/55R17, while the Tribeca uses 255/55R18. These are all radial sizes, and they do not share the same rim diameter, since the fitments span 16-, 17-, and 18-inch wheels. Rim width guidance is available for the 16-inch and 17-inch sizes, with 215/65R16 products covering roughly 5.50 to 7.50 inches and 225/55R17 products covering about 6.0 to 9.0 inches depending on the tire.

That means the right starting point for a 2011 Subaru Trucks vehicle is always the exact model, followed by the wheel diameter already on the vehicle. A Forester owner may need to verify whether the vehicle is on 16-inch or 17-inch wheels before choosing a tire, while a Tribeca owner should stay within the 18-inch fitment family. If the wheels are not original, checking the stamping on the wheel itself is worth the extra step before making a final size choice.

On a 2011 Subaru Trucks tire, 215/65R16 is a metric radial size. The 215 is the section width in millimeters, 65 is the aspect ratio, meaning the sidewall height is 65 percent of the section width, the R indicates radial construction, and 16 is the wheel diameter in inches. Within the 2011 Subaru Trucks range, this size belongs to the Forester rather than the Tribeca.

The practical takeaway is that 215/65R16 tells you both the physical size family and the wheel diameter the tire must mount on. It does not automatically make the tire right for every Forester, because wheel diameter still needs to match the vehicle. Once that is confirmed, the choice shifts to the kind of tire you want in that size, such as a black sidewall utility tire or a more appearance-driven redline or whitewall version.

No, 2011 Subaru Trucks models do not all use the same tire size. The Forester uses two different sizes, 215/65R16 and 225/55R17, while the Tribeca uses 255/55R18. All three are radial sizes, but they are separated by model and wheel diameter rather than shared across the entire year and make.

That matters because year and make alone are not enough for a confident tire choice on a 2011 Subaru Trucks vehicle. Forester owners need to identify whether their vehicle is set up for 16-inch or 17-inch tires, and Tribeca owners should confirm the 18-inch fitment. If you are comparing options for appearance, ride character, or restoration style, do that only after the model and wheel size are nailed down first.

2011 Subaru Trucks tire choices include several sidewall styles, depending on size. In 215/65R16, BFGoodrich offers RBL, redline, and wide whitewall versions. In 225/55R17, BFGoodrich offers blackwall and wide whitewall versions. The 255/55R18 fitment does not have a sidewall style range shown here, so most of the visible variety within this year and make centers on the Forester's 16-inch and 17-inch sizes.

That sidewall range gives owners room to match the tire to the personality of the vehicle. A black sidewall or RBL look generally suits a more contemporary, understated presentation, while redline and whitewall styles lean toward custom or nostalgic visual themes. On a 2011 Subaru Trucks vehicle, sidewall style is mostly an appearance decision after the correct size and wheel diameter have been confirmed.

BFGoodrich covers the available 2011 Subaru Trucks fitments shown here. The 215/65R16 size for the Forester appears in BFGoodrich All-Terrain T/A KO2 and BFGoodrich Silvertown Radial form, while the 225/55R17 Forester fitment includes BFGoodrich g-Force and Silvertown Radial choices. The Tribeca's 255/55R18 size is part of the year-and-make fitment range, but brand coverage is not expanded here the way the Forester sizes are.

For the buyer, that means brand comparison within 2011 Subaru Trucks fitments is really a series comparison inside BFGoodrich rather than a broad brand-versus-brand decision. A utility-oriented all-terrain, a performance-oriented blackwall radial, and a whitewall or redline presentation all create different ownership experiences even when the brand name stays the same. Once your model and size are confirmed, focus on series character and sidewall style rather than just the brand badge.

For a 2011 Subaru Trucks Forester in 215/65R16, BFGoodrich All-Terrain T/A KO2 and BFGoodrich Silvertown Radial serve very different purposes. The KO2 carries a 1,930-pound load rating at 65 psi, fits 6.0- to 7.5-inch rims, uses an RBL sidewall, and weighs 34 pounds. The Silvertown Radial versions carry 1,565 pounds at 35 psi, fit 5.50- to 7.50-inch rims, and come in redline or wide whitewall form at 25 pounds each.

That comparison makes the choice less about basic fit and more about character. The KO2 leans toward a tougher, utility-focused look and heavier-duty service, while the Silvertown Radial options lean toward visual distinction with more traditional sidewall styling. A Forester owner deciding between them should think about how the vehicle is used, what appearance is desired, and whether the wheel falls within the published rim-width range for the specific tire.

Rim width depends on the size and the specific tire chosen for a 2011 Subaru Trucks vehicle. In 215/65R16, published ranges run from 5.50 to 7.50 inches on the Silvertown Radial versions and 6.0 to 7.5 inches on the All-Terrain T/A KO2. In 225/55R17, BFGoodrich options span 6.0 to 8.0 inches on the g-Force tires and up to 6.00 to 9.00 inches on the Silvertown Radial whitewall.

The important point is that tire size alone does not settle rim-width compatibility. A 2011 Subaru Trucks Forester owner choosing between different 17-inch products, for example, should still confirm that the wheel width falls inside the range for that exact tire. Matching the tire to both the wheel diameter and the approved rim width helps preserve the intended tread shape, ride quality, and steering response.

The 2011 Subaru Trucks fitments shown here are radial passenger and light-truck sizes, and none of these products are marked as tube-type. The 215/65R16 and 225/55R17 offerings appear in modern radial form without TT markings, which points toward tubeless construction in normal use on appropriate wheels. That aligns with what most buyers would expect from 2011-era Subaru applications.

Even so, the wheel itself still matters. If a 2011 Subaru Trucks vehicle is running original factory-style tubeless wheels in sound condition, a tube is generally not part of the plan. If the vehicle has unusual aftermarket wheels, damage at the bead seat, or another wheel-specific issue, solve that wheel problem first rather than assuming a tube is the answer.

A 2011 Subaru Trucks vehicle should be stored clean, dry, and out of direct sunlight, with the tires kept away from ozone-producing equipment such as electric motors, chargers, welders, and some compressors. Tire pressure should be maintained during storage, and the vehicle should be rolled periodically so one section of tread does not carry the same load for months at a time. Because these fitments are all radial, they generally recover from temporary flat spotting better than older bias-ply designs, but long static storage is still hard on any tire.

For seasonal or low-mileage collector use, the best routine is simple and consistent. Keep the tires inflated, move the vehicle occasionally, and use stands only if the vehicle will sit for a very long period and you know how to support it correctly. Good storage habits protect sidewalls, help prevent vibration on the next drive, and reduce the chance of age-related cracking before the tread is actually worn out.

On a 2011 Subaru Trucks vehicle, tire life should be judged more by age and condition than by mileage alone, especially if the vehicle sees occasional use. A good rule is to begin evaluating tires carefully at around five to seven years from the date of manufacture and to treat ten years as a strong point for replacement consideration regardless of remaining tread. The DOT date code on the sidewall tells you when the tire was made.

That matters because many collector-driven or low-mileage vehicles age out their tires before they wear them out. A 2011 Subaru Trucks Forester or Tribeca that spends long periods parked can still develop sidewall cracking, internal aging, or loss of ride quality even if the tread looks acceptable at a glance. If there is any doubt, age and condition should outweigh mileage when deciding whether a tire remains serviceable.

Tires on a 2011 Subaru Trucks vehicle should be checked before every drive and given a more thorough inspection before any longer outing. Look for cuts, bulges, weather checking, irregular wear, and any sign that the tire is losing pressure. Because these Subaru fitments include different wheel diameters and load capacities depending on size, it is also smart to verify that all four tires match the intended size and specification for the vehicle.

A short walk-around catches many problems before they become roadside problems. Pay attention to sidewalls, tread shoulders, and valve stems, then confirm pressures when the tires are cold. On a vehicle that may alternate between local errands and longer weekend trips, regular inspection is one of the simplest ways to protect both the tires and the driving experience.

2011 Subaru Trucks tires can be suitable for highway driving when the size, load capacity, condition, and speed rating match the vehicle's use. The 225/55R17 fitment includes W-rated products, which carry a 168 mph ceiling, and the 215/65R16 options include products marked 103S, with an S rating corresponding to 112 mph. Those ceilings are well above normal U.S. highway speeds, but they are not a reason to ignore age, inflation, or vehicle condition.

On a 2011 Subaru Trucks vehicle, real-world safety often depends just as much on the condition of the suspension, alignment, brakes, and wheel condition as on the tire itself. Choose a tire that matches the vehicle's intended use, keep it properly inflated, and avoid pushing an older or rarely driven vehicle beyond the level its overall mechanical condition supports. Safe highway use starts with the whole package, not just the number on the sidewall.

Inflation pressure for a 2011 Subaru Trucks tire should follow the vehicle placard or owner's manual first, then be checked against the tire's own maximum load and pressure markings where applicable. In 215/65R16, one BFGoodrich option carries 1,930 pounds at 65 psi, while Silvertown Radial versions carry 1,565 pounds at 35 psi. In 225/55R17, some products carry 1,609 at 51 psi or 1,819 pounds at 50 psi. Those figures are the tire's rated limits, not universal operating pressures for every Subaru application.

The key is not to transfer a pressure from one size or tire line to another. A 2011 Subaru Trucks Forester on 215/65R16 tires may require a different operating pressure than a Forester on 225/55R17, and a maximum sidewall figure is not the same thing as the vehicle maker's recommended cold pressure. Use the factory recommendation as the baseline, then confirm that the chosen tire's load capacity supports how the vehicle will actually be used.

Before taking a 2011 Subaru Trucks vehicle on a longer drive, inspect each tire for cracking, cuts, bulges, punctures, uneven wear, and proper cold inflation pressure. Check the valve stems, confirm the spare is usable, and make sure all four road tires are the correct size family for the vehicle, especially on a Forester where both 16-inch and 17-inch fitments exist. If the tires are older, verify the DOT date code as part of the inspection.

Tires are only one part of the pre-trip routine on a vehicle of this age. A longer drive is also the right time to check wheel condition, alignment behavior, brake feel, and whether the vehicle tracks straight without vibration. Catching a weak valve stem, an aging spare, or a mismatched tire before departure is far easier than solving it on the shoulder of the road.
