The 2013 Subaru Trucks Tribeca came at the close of Subaru’s run with this three-row crossover, a model known for blending all-weather practicality with a more upscale family-vehicle mission than the brand’s smaller utility offerings. For owners keeping one on the road today, tire fitment is refreshingly straightforward. The 2013 Subaru Trucks Tribeca uses a 255/55R18 radial tire, giving the search less about decoding multiple factory sizes and more about choosing the right tire within that fitment. The real comparison centers on overall tire character, road-use priorities, and making sure wheel condition, suspension health, and present-day vehicle setup still match the intended size.
Which Tire Size Is Right for The 2013 Subaru Trucks Tribeca
The 2013 Subaru Trucks Tribeca uses one primary tire size: 255/55R18, and it is a radial fitment on an 18-inch rim. On this vehicle, the main decision is not sorting through several factory sizes, but choosing the right 255/55R18 tire for the way the Tribeca is used and confirming that the wheels and overall vehicle setup still match the original sizing approach.
A 255/55R18 size uses modern metric sizing: 255 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 18 is the wheel diameter in inches. On a 2013 Subaru Trucks Tribeca, this is a modern radial fitment rather than a vintage bias-ply or alphanumeric size, so the code is familiar to current drivers and service shops. That makes product selection more about tire type, driving priorities, and condition of the existing wheels. It is the correct starting point when replacing worn tires or confirming whether a modified Tribeca still matches its intended fitment.
Sub-model fitment for the 2013 Subaru Trucks Tribeca is simple within the covered range. Checking the exact trim still matters, but the Limited follows the same straightforward sizing pattern with the 255/55R18 radial on an 18-inch rim.

Frequently Asked Questions
Owners usually want quick answers on 255/55R18 fitment, 18-inch rim compatibility, trim-level consistency, and what to inspect before putting a 2013 Subaru Trucks Tribeca back into regular road use.
Tire Size & Fitment
What tire size fits a 2013 Subaru Trucks Tribeca?
The 2013 Subaru Trucks Tribeca uses a 255/55R18 tire size. This is a radial tire in modern metric format, with 255 indicating nominal section width in millimeters, 55 representing the aspect ratio, and 18 identifying the wheel diameter in inches.
That means the first step is confirming that the Tribeca still has the correct 18-inch wheels and a stock-style setup. If the vehicle has aftermarket wheels, suspension changes, or a previous owner installed a different size, checking wheel width, clearance, and overall condition before replacement helps keep the next tire choice aligned with the intended fitment.
What size rim does a 2013 Subaru Trucks Tribeca use?
The 2013 Subaru Trucks Tribeca uses an 18-inch rim with its 255/55R18 tire size. In that size code, the final number, 18, refers to wheel diameter, so the tire is built to mount on an 18-inch wheel rather than a smaller or larger rim.
Rim diameter is only one part of the fitment picture, so wheel width and overall wheel condition still matter. A Tribeca that has had wheel swaps in the past may still wear 18-inch wheels but differ in width or offset, which can affect tire behavior and clearance even when the basic diameter appears correct.
Does the 2013 Subaru Trucks Tribeca Limited use the same tire size?
Yes. The 2013 Subaru Trucks Tribeca Limited uses the same 255/55R18 radial tire size. That keeps trim-level fitment straightforward and avoids the need to sort through multiple factory tire sizes within the covered sub-model information.
Even with shared size information, it is still smart to verify what is actually on the vehicle before ordering replacements. A used Tribeca Limited may have replacement wheels or a nonstandard tire from a previous service visit, so matching the tire to the current wheel setup is just as important as matching it to the trim name.
Choosing the Right Tire
What should I consider when choosing a 255/55R18 tire for a 2013 Subaru Trucks Tribeca?
Start with the correct size, which is 255/55R18 for the 2013 Subaru Trucks Tribeca. Since the fitment is already a modern radial, the main decision is choosing a tire that suits how the vehicle is driven, whether that means routine commuting, seasonal family use, or lower-mileage service.
Beyond size, compare the condition and specifications of the wheels currently on the vehicle and look at the overall use of the Tribeca. Ride expectations, road conditions, and whether the vehicle is kept mostly stock all shape the final choice, and a careful check of wheel compatibility helps avoid selecting a tire that only looks right on paper.
How do I choose between available 255/55R18 tires for a 2013 Subaru Trucks Tribeca?
Choosing between 255/55R18 tires for a 2013 Subaru Trucks Tribeca comes down to selecting the right type of radial tire within the correct size. Since there is one primary fitment, the process is less about size matching and more about finding a tire that suits the vehicle’s current use and present condition.
A Tribeca used regularly on modern roads may call for a different selection approach than one driven occasionally and stored for long periods. It also helps to inspect the wheels, alignment condition, and suspension wear before replacement, because those factors influence how well any correctly sized tire will perform once installed.
What does 255/55R18 mean on a 2013 Subaru Trucks Tribeca?
On a 2013 Subaru Trucks Tribeca, 255/55R18 is a modern metric radial tire size. The 255 is the nominal tire width in millimeters, 55 is the sidewall profile expressed as an aspect ratio, R means radial construction, and 18 is the wheel diameter in inches.
Understanding the code helps when checking what is already on the vehicle or comparing replacement options. It also makes it easier to spot a mismatch if a previous owner fitted a different size, and that is worth catching early because wheel diameter, tire profile, and overall clearance all need to work together on the Tribeca.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Subaru Trucks Tribeca?
A period-appropriate starting point for a 2013 Subaru Trucks Tribeca is the original-size 255/55R18 radial fitment. Because this is already a modern metric radial application, keeping the correct size does more for the vehicle’s intended stance and overall presentation than chasing an alternative size that changes the look.
Appearance-minded owners should focus on preserving the Tribeca’s stock-style proportions and making sure the wheels remain true to the vehicle’s original setup. On a newer collector-era utility vehicle like this, size accuracy and wheel condition usually matter more than vintage-style construction choices, since the factory-era presentation was already built around radial tires.
Does correct tire fitment matter for a 2013 Subaru Trucks Tribeca restoration?
Yes, correct tire fitment matters on a 2013 Subaru Trucks Tribeca restoration because the 255/55R18 size helps preserve the vehicle’s intended proportions and wheel relationship. Even on a later model, tire size affects stance, wheel-well appearance, and how authentic the finished vehicle looks in everyday use.
A restoration-oriented approach should include checking that the wheels are the proper diameter and that replacement tires do not stray from the original fitment without a reason. For owners aiming at a highly accurate presentation, comparing the current setup to vehicle-specific literature or marque references can help confirm that the finished look stays appropriately faithful.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Subaru Trucks Tribeca?
Yes, modifications can affect tire fitment on a 2013 Subaru Trucks Tribeca even when the target size remains 255/55R18. Changes such as aftermarket wheels, altered offset, suspension lowering, spring replacement, or body modifications can influence clearance and how the tire sits within the wheel opening.
That is why the current vehicle setup matters as much as the published size. A Tribeca that no longer uses its original-style wheels may need closer checking at the fenders, steering components, and suspension before replacement tires are installed, especially if the vehicle has seen custom work or nonstandard wheel and tire combinations in the past.
What should I inspect before driving a 2013 Subaru Trucks Tribeca on new tires?
Before driving a 2013 Subaru Trucks Tribeca on new tires, inspect the wheels for damage, verify the tire size is 255/55R18, and check for obvious suspension or steering wear. It is also smart to look over valve stems, confirm proper inflation, and make sure there is no rubbing at full steering lock.
A fresh set of tires cannot compensate for worn alignment parts or bent wheels, so the vehicle should be road-ready before regular use resumes. On a used or lower-mileage Tribeca, it also helps to watch for uneven wear patterns, vibration, or air loss during the first drives, since those signs can reveal setup issues that were already present.
How often should tires on a 2013 Subaru Trucks Tribeca be inspected?
Tires on a 2013 Subaru Trucks Tribeca should be inspected regularly, especially on a vehicle that may alternate between daily use and longer parked periods. Check for tread wear, cuts, bulges, cracking, punctures, and any loss of air pressure, because age and storage conditions can affect tires even when mileage stays relatively low.
Routine inspection is particularly important before highway driving or seasonal use. A Tribeca that spends time parked should also be kept away from prolonged sun, moisture, and ozone sources when possible, and any tire showing visible deterioration or repeated pressure loss deserves closer evaluation before the vehicle is put back into normal road service.
