2011 Subaru marked a mature point in the brand’s U.S. lineup, with the Impreza carrying Subaru’s compact all-wheel-drive character, the Legacy serving as the midsize sedan choice, and the Outback leaning toward wagon utility and light adventure use. That broad mission spread means tire sizing varies significantly across the range rather than staying uniform across the make. In all, three models use ten distinct radial sizes, and the real choice starts with identifying the exact model and wheel diameter before narrowing down tread style, sidewall appearance, and driving intent. For 2011 Subaru fitment, confirm your model first, then verify the wheel diameter already on the car before choosing a tire.
Which Tire Size Is Right for Your 2011 Subaru
2011 Subaru vehicles use 10 different tire sizes, and those sizes vary by model rather than being shared across the full lineup. Every size here is a radial, so the main decision is not bias-ply versus radial construction, but matching the correct model and wheel diameter first, then choosing the sidewall style and product character that suit how the car is used. Understanding that distinction before choosing a product saves time and helps you match the tire to the right Subaru.

Three 2011 Subaru model lines are covered here: Impreza, Legacy, and Outback. They do not share a common tire size across the range, so identifying the exact model matters before choosing a tire. Select a model below to narrow the fitment history and see the sizes and products that apply to that particular Subaru.
2011 Subaru Impreza
The 2011 Subaru Impreza carried Subaru’s compact all-wheel-drive formula in sedan and hatchback forms, with fitments ranging from everyday 16-inch applications to more aggressive 17- and 18-inch combinations. Its tires mount on 16-, 17-, or 18-inch wheels depending on version, so the wheel already on the car is the first thing to verify before choosing a replacement.
The 2011 Subaru Legacy was Subaru’s midsize sedan, aimed at buyers who wanted more cabin room and a more substantial road-car feel than the Impreza. Legacy tires mount on 16-, 17-, or 18-inch wheels depending on configuration, making the exact wheel diameter the key detail to confirm before moving to a tire choice.

205/60R16 — radial, 16-inch fitment with classic whitewall look
The 2011 Subaru Outback blended wagon practicality with higher-riding crossover character, which is reflected in its taller-profile tire sizing. Outback fitments here mount on either 16- or 17-inch wheels, and that taller sidewall profile is part of what gives the model its more utility-oriented stance and ride character.
Thirty-five products are available across 10 tire sizes for 2011 Subaru vehicles. Coverage ranges from 205/55R16 through 245/40R18 for the Impreza, 205/60R16 through 225/45R18 for the Legacy, and 215/70R16 or 225/60R17 for the Outback, with brands including BFGoodrich, Michelin, Nitto, American Classic, Coker Classic, Travelstar, and M&H Racemaster. Confirm the exact size and wheel diameter first, since sidewall style, speed rating, and tubeless marking can vary by product.
These answers cover how 2011 Subaru tire sizes differ by Impreza, Legacy, and Outback, what the metric size codes mean, which sidewall styles and brands are offered, and what to check before fitting collector-oriented or low-mileage replacement tires.
Size Basics & Fitment
What tire sizes fit 2011 Subaru vehicles?
2011 Subaru vehicles use 10 distinct tire sizes across three model lines. The Impreza uses 205/55R16, 205/50R17, 235/45R17, and 245/40R18; the Legacy uses 205/60R16, 215/50R17, 225/50R17, and 225/45R18; and the Outback uses 215/70R16 and 225/60R17. Rim diameters span 16, 17, and 18 inches, with product rim-width ranges varying by size from narrow 5.5-inch applications up to 9.5-inch fitments in the wider sport-oriented sizes.
That means year and make alone are not enough for a safe starting point on a 2011 Subaru. You need the model first, then the wheel diameter already on the car, and then the exact size on the sidewall or door-jamb placard. Once those basics match, you can narrow the choice by sidewall style, load capacity, and the kind of driving the car actually sees.
What does 205/55R16 mean on a 2011 Subaru tire?
On a 2011 Subaru, 205/55R16 is a metric radial tire size. The 205 is the nominal section width in millimeters, 55 is the aspect ratio, the R identifies radial construction, and 16 is the wheel diameter in inches. For 2011 Subaru fitment, this size belongs to the Impreza and is offered on 16-inch wheels with product rim-width recommendations centered around 5.5 to 7.5 inches.
Understanding that code helps separate wheel fitment from tread or brand preference. A 205/55R16 tire will not interchange with a 17- or 18-inch Subaru wheel simply because the widths seem close. If your Impreza currently wears 16-inch wheels, this size keeps you in the correct diameter family before you compare blackwall performance-oriented options from different manufacturers.
Do all 2011 Subaru models use the same tire size?
No. 2011 Subaru models do not share a single tire size across the lineup. The Impreza, Legacy, and Outback each use their own group of sizes, and even within the Impreza and Legacy families, more than one wheel diameter appears. The Outback also stands apart with taller-profile sizes such as 215/70R16 and 225/60R17 that reflect its wagon-crossover mission.
That matters because a Subaru owner can easily know the year and make correctly but still order the wrong tire by assuming all-wheel-drive cars from the same brand share the same dimensions. If you are unsure, start by confirming whether you have an Impreza, Legacy, or Outback, then verify the existing wheel diameter and compare the sidewall code before choosing among the available products.
Buying the Right Tire
What sidewall styles are available for 2011 Subaru tires?
2011 Subaru tire options include several sidewall treatments depending on size. Many Impreza and Legacy sport-oriented sizes are available as blackwalls, while select Legacy and Outback sizes also appear with wide whitewall, narrow whitewall, or RWL styling. Examples include wide whitewall versions in 205/50R17, 205/60R16, and 215/70R16, an RWL option in 215/70R16, and a narrow whitewall option in 225/60R17.
For most 2011 Subaru buyers, blackwall styling will feel most natural to the car’s original look, especially on Impreza and Legacy applications with lower-profile tires. Whitewall and RWL alternatives are more appearance-driven choices, so they work best when the owner is intentionally building a custom look rather than trying to preserve a factory-modern presentation. Sidewall style can dramatically change the personality of the car even when the size stays correct.
What brands make tires for 2011 Subaru vehicles?
2011 Subaru coverage includes BFGoodrich, Michelin, Nitto, American Classic, Coker Classic, Travelstar, and M&H Racemaster, depending on size. BFGoodrich appears across much of the Impreza and Legacy range, Michelin appears in 205/55R16, Nitto covers several 17- and 18-inch blackwall sizes, American Classic supplies whitewall choices in select 16- and 17-inch sizes, Coker Classic appears in 215/70R16, Travelstar in 225/60R17, and M&H Racemaster in 245/40R18.
Brand choice on a 2011 Subaru often comes down to the visual style and intended use of the car rather than basic compatibility alone. Some sizes are strongly sport-oriented in their available brands, while others open the door to a more custom whitewall presentation. Once the correct size is confirmed, compare the available brands within that size rather than trying to cross-shop brands from a different Subaru fitment.
What is the difference between BFGoodrich and Nitto options for 2011 Subaru tires?
On 2011 Subaru sizes where both brands appear, BFGoodrich and Nitto often cover the same wheel diameter but with slightly different load and rim-width details. In 235/45R17, BFGoodrich products use a 7.5 to 9.0-inch rim-width range, while the Nitto NT555 G2 uses 7.5 to 9.0 inches with an 8.0-inch measuring width and carries a 1,609-pound load figure at 50 psi. In 245/40R18, BFGoodrich spans 8.0 to 9.5 inches, while Nitto uses 8.0 to 9.5 with an 8.5-inch measuring width and also reaches 1,609 pounds at 50 psi.
Those differences are small but useful when you are matching the tire to the exact wheel already on the car. If your Subaru sits near the narrow or wide end of the acceptable rim range, those details help narrow the field. The best approach is to confirm the wheel width first, then compare the tire’s load and rim-width specifications within the exact size your Subaru requires.
Fitting & Setup
What rim width do 2011 Subaru tires require?
Rim-width requirements on 2011 Subaru tires vary by size. 205/55R16 and 205/50R17 generally use 5.5 to 7.5-inch wheels, 235/45R17 uses about 7.5 to 9.0 inches, 245/40R18 uses 8.0 to 9.5 inches or 8.5 inches on the drag radial, 225/45R18 uses 7.0 to 8.5 inches, 215/50R17 uses 6.0 to 7.5 inches, 225/50R17 uses 6.0 to 8.0 inches, and 215/70R16 runs roughly 5.5 to 7.5 inches. The 225/60R17 option appears on a 6.5J wheel.
That spread shows why tire size alone is only part of the fitment picture on a 2011 Subaru. Two tires may share the same wheel diameter while asking for very different wheel widths. Before mounting anything, verify the actual width of the wheel on the car and compare it to the acceptable range for the specific size you intend to run.
Do 2011 Subaru tires require inner tubes?
Most 2011 Subaru tire options here are radial passenger tires intended for modern wheel use, and one 205/55R16 Michelin product is explicitly marked TL for tubeless use. Several other sizes do not show a tube-type marking and follow the same general modern radial pattern, while some size descriptions simply do not carry a visible tube notation in the sidewall code. None of the 2011 Subaru sizes here are presented as all tube-type fitments.
On a 2011 Subaru, the practical step is to match the tire to the wheel condition and the exact sidewall marking of the product you choose. If you are working with original late-model Subaru wheels in sound condition, tubeless fitment is the norm, but it is still wise to inspect bead seats and valve stems carefully during installation. When the sidewall marking differs between products, follow the individual tire’s marking rather than assuming every tire in that size is identical.
Can the original 2011 Subaru wheels be used with all tire sizes?
Original 2011 Subaru wheels can only be used with tire sizes that match their wheel diameter and fall within an appropriate rim-width range. A 16-inch wheel takes a 16-inch tire, a 17-inch wheel takes a 17-inch tire, and an 18-inch wheel takes an 18-inch tire. Beyond diameter, the wheel width must still suit the size, which is why a 235/45R17 and a 205/50R17 are not automatically interchangeable even though both fit 17-inch wheels.
That means wheel re-use is often possible within the correct diameter family, but not across the entire 2011 Subaru range. Before changing from one approved size to another on the same diameter, confirm the wheel width and compare it to the tire’s acceptable range. That step matters most on wider Impreza and Legacy fitments, where the difference between a narrow OE wheel and a wider performance wheel can affect suitability.
Maintenance, Storage & Longevity
How should I store a 2011 Subaru when the tires are fitted?
A 2011 Subaru stored on its tires should be kept in a cool, dry space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone sources that accelerate rubber aging. Maintain proper inflation, keep the tires clean, and move the vehicle occasionally so the same contact patch is not supporting the car for months at a time. Modern radials resist flat-spotting better than older bias-ply designs, but long static storage can still leave temporary flat spots and stress the sidewalls.
For seasonal or collector use, many owners either roll the car periodically or support it in a way that reduces long-term load on the tires. The goal is not just preserving tread, but protecting the carcass and sidewalls from age-related damage. If your 2011 Subaru sits for extended periods, include tire pressure and sidewall checks in the same routine as battery maintenance and fluid inspection.
How long do tires on a 2011 Subaru typically last?
On a 2011 Subaru that sees collector-style or low annual mileage use, tire age usually matters more than tread wear. A good rule is to begin evaluating tires carefully once they reach about five to seven years of age and to treat the ten-year mark as the point where replacement deserves serious consideration, even if tread depth still looks usable. The DOT date code on the sidewall tells you when the tire was made.
That age-based approach is especially important on cars that spend more time parked than driven, because rubber hardens and cracks long before tread disappears. A 2011 Subaru with attractive-looking tires can still be riding on rubber that has aged out. If you are unsure whether age or wear is the bigger issue, use the date code as your starting point and then inspect the tire’s overall condition.
How often should tires on a 2011 Subaru be inspected?
Tires on a 2011 Subaru should be inspected before every drive, with a more deliberate check before any longer outing or highway trip. Look for cracking, cuts, bulges, punctures, uneven wear, and any sign that the tire is losing pressure. Valve stems also deserve close attention on a modern radial setup, because a dry or damaged stem can create the same kind of trouble as a damaged tire body.
A quick visual walk-around catches many problems before they become road issues, especially on a Subaru that may sit between drives. If the car has recently come out of storage, inspect the tread face and both sidewalls after the first few miles as well. That second look can reveal flat-spotting, slow leaks, or age-related cracking that was easy to miss while the car was parked.
Restoration & Authenticity
What tires were originally fitted to the 2011 Subaru Impreza?
A 2011 Subaru Impreza was originally part of a modern radial-tire era, so radial construction is the correct starting point for authenticity as well as normal use. The Impreza fitments here are 205/55R16, 205/50R17, 235/45R17, and 245/40R18, all in metric radial form. Original-equipment details could vary by body style, trim, and market package, so the exact sidewall branding and speed category should be confirmed against the door-jamb placard, owner literature, or a marque specialist.
For a factory-correct presentation, the biggest authenticity markers are the exact size, wheel diameter, and a sidewall appearance that suits a 2011 Japanese performance-oriented compact. Blackwall styling will usually align more naturally with that period than a custom whitewall treatment. If the car has changed hands or wheels over the years, verify what is on the car now before treating any current tire size as original.
Does correct tire fitment matter for showing a 2011 Subaru?
Correct tire fitment does matter when a 2011 Subaru is being judged or presented seriously, even though the standards are usually less rigid than they are for prewar or muscle-era concours cars. Judges and knowledgeable enthusiasts will notice if the car wears the wrong diameter, an obviously incorrect profile, or a sidewall style that clashes with the model’s period appearance. On a late-model Subaru, the visual difference between a proper blackwall sport radial and a custom whitewall can be especially noticeable.
For most 2011 Subaru show purposes, getting the size right is the first priority, followed by choosing a sidewall style that matches the look you want the car to convey. Owners pursuing factory-style presentation should verify trim-specific expectations with Subaru clubs or event organizers. Owners building a personalized show car have more freedom, but the tire should still match the wheel diameter and intended stance correctly.
What is the difference between blackwall and whitewall tires for a 2011 Subaru?
On a 2011 Subaru, the difference between blackwall and whitewall tires is primarily visual rather than dimensional when the same size is used. Blackwall options dominate most Impreza and Legacy performance-oriented sizes, while whitewall choices appear in selected Legacy and Outback sizes such as 205/50R17, 205/60R16, 215/70R16, and 225/60R17. The tire still has to match the correct size and wheel diameter either way.
For a factory-modern appearance, blackwalls are generally the more natural fit on a 2011 Subaru. Whitewalls create a custom look and can work well when that is the deliberate goal, especially on an Outback or a personalized Legacy, but they shift the car away from an original showroom style. If authenticity matters, choose the sidewall treatment with the same care you give to the wheel design and ride height.
Safety & Road Use
Are 2011 Subaru tires safe for highway driving?
2011 Subaru tires can be appropriate for highway driving when the tire is the correct size, in sound condition, and used within its rated capability. Most of the sport-oriented sizes here carry W ratings, which correspond to a 112 mph ceiling, one 205/55R16 Michelin option carries a Y rating at 186+ mph, the 225/60R17 option carries a T rating at 118 mph, and one 215/70R16 option carries an R rating at 106 mph. All of those ratings exceed normal U.S. highway speeds when the tires are properly maintained.
Real-world safety in a 2011 Subaru depends just as much on age, inflation, alignment, suspension condition, and brake condition as it does on the speed symbol molded into the sidewall. A high speed rating does not cancel out cracked rubber or a bent wheel. Before a long highway run, confirm the tire’s condition first and treat the speed rating as a limit, not as a target.
What inflation pressure should I use for 2011 Subaru tires?
Inflation pressure on 2011 Subaru tires should start with the vehicle’s factory recommendation, then be checked against the tire manufacturer’s rated pressure information for the exact tire you choose. Several sizes here include maximum load and pressure pairings, such as 205/60R16 at 1,356 pounds and 35 psi, 225/50R17 at up to 1,653 pounds and 50 psi, 215/70R16 from 1,709 pounds at 35 psi to 2,094 pounds at 32 psi depending on the tire, and 225/60R17 at 1,709 pounds and 44 psi.
Those figures are not interchangeable across sizes, and they are not automatic fill targets for everyday use. Maximum pressure is tied to maximum load capacity, not necessarily to the pressure Subaru intended for ride, handling, and tire wear on the car. Use the door-jamb placard or owner’s manual for the vehicle baseline, then make sure the chosen tire’s own limits are respected.
What should I check before taking a 2011 Subaru on a longer drive?
Before a longer drive in a 2011 Subaru, inspect every tire for cracks, cuts, bulges, embedded objects, uneven wear, and correct cold inflation pressure. Check the valve stems, confirm the tread is free of visible damage, and make sure the spare is present and serviceable. If the car has been parked for a while, the first few miles should include extra attention for vibration or flat-spotting, especially on lower-profile 17- and 18-inch fitments.
Tires are only one part of the pre-trip routine, but they are the part that connects every other system to the road. A Subaru with good all-wheel-drive hardware still depends on healthy, correctly sized tires to behave predictably. Before setting out, combine the tire check with a broader inspection of brakes, fluid levels, lights, and general chassis condition so the car is ready for the distance.
