The 2009 Toyota Yaris came from a period when small cars were expected to deliver efficient daily transportation without giving up modern road manners. Its compact footprint, simple packaging, and light curb weight still make it a practical choice for owners who want an easy-to-live-with hatchback or sedan. Tire fitment on the 2009 Toyota Yaris centers on two radial sizes, with 175/65R14 and 185/60R15 tied to different sub-models. That makes the main decision less about vintage construction and more about confirming the exact trim, wheel diameter, and the kind of road feel and appearance you want. Getting that part right keeps replacement shopping straightforward.
Which Tire Size Is Right for The 2009 Toyota Yaris
The 2009 Toyota Yaris uses two primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. The Base uses a 14-inch radial fitment, while the S uses a 15-inch radial fitment. Before choosing a tire, confirm which trim the car is and verify the wheels currently on it, especially if it has been changed from stock sizing.
175/65R14 is a metric radial size in which 175 identifies the section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 14 is the rim diameter in inches. On the 2009 Toyota Yaris, this size is the primary fitment for the Base model and reflects a straightforward modern small-car tire format. The size is oriented toward practical replacement rather than vintage-style construction decisions, so the focus is on matching the correct dimensions and wheel diameter. It is the right place to start when the car has 14-inch wheels and original-style Base fitment.
185/60R15 is a metric radial size where 185 is the nominal section width in millimeters, 60 is the aspect ratio, R marks radial construction, and 15 is the wheel diameter in inches. For the 2009 Toyota Yaris, this size belongs to the S sub-model and uses a different rim diameter than the Base. That makes wheel confirmation especially important before replacement, since the two Yaris fitments are not simply alternate labels for the same setup. Choose this size when the car is an S or when the vehicle is equipped with the correct 15-inch wheel package.
Sub-model fitment matters on the 2009 Toyota Yaris because the covered trims do not share the same tire size. The first step is confirming whether the car is a Base or an S, since each uses a different radial size and wheel diameter.

2009 Toyota Yaris Base
The 2009 Toyota Yaris Base uses a 175/65R14 radial tire on a 14-inch wheel setup. For replacement, the important step is staying with the correct 14-inch fitment and checking that the car has not been changed to a different wheel size over time.
The 2009 Toyota Yaris S uses a 185/60R15 radial tire and a 15-inch wheel package. That means tire selection should begin with wheel confirmation, since moving between the Base and S fitments requires more than choosing a different section width.
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.
Frequently Asked Questions
These FAQs focus on the exact tire sizes used on the 2009 Toyota Yaris, how Base and S fitments differ, and what to check before replacing tires on a compact car that may have seen wheel or suspension changes over time.
Tire Size & Fitment
What tire size fits a 2009 Toyota Yaris?
A 2009 Toyota Yaris uses one of two radial tire sizes depending on sub-model. The Base uses 175/65R14, while the S uses 185/60R15. Both are modern metric radial sizes, but they are tied to different wheel diameters, so they are not interchangeable choices for the same wheel.
The practical first step is confirming whether the car is a Base or an S and then checking the wheels currently on the vehicle. A Yaris that has had wheels changed over the years may no longer match its original trim-based setup, so replacement should always start with the actual wheel diameter and existing fitment.
What size rim does a 2009 Toyota Yaris use?
The 2009 Toyota Yaris uses either a 14-inch or 15-inch rim, depending on sub-model. The Base pairs with a 14-inch wheel and the 175/65R14 tire size, while the S uses a 15-inch wheel with the 185/60R15 tire size. Rim diameter is part of the tire size itself, so it needs to match exactly.
Checking the wheel before ordering tires matters because a 14-inch tire cannot be mounted on a 15-inch rim, and the reverse is equally true. If the car has aftermarket wheels, confirm the wheel diameter from the tire sidewall and inspect the wheel itself so the replacement tire matches the setup actually on the vehicle.
Why does the 2009 Toyota Yaris have more than one tire size?
The 2009 Toyota Yaris has more than one tire size because different sub-models use different wheel and tire packages. The Base uses 175/65R14, while the S uses 185/60R15. Both are correct fitments within the Yaris line, but each belongs to a specific trim rather than being universal across every 2009 Yaris.
That distinction affects replacement shopping right away. Instead of choosing between two sizes based on preference alone, identify the exact sub-model and verify the wheel diameter on the car. A vehicle that has been modified or fitted with wheels from another Yaris trim should be matched to its present wheel setup, not just the trim name on paper.
Choosing the Right Tire
What should I consider when choosing a 175/65R14 or 185/60R15 tire for a 2009 Toyota Yaris?
Start with the correct size for the exact sub-model and wheel diameter. A 2009 Toyota Yaris Base uses 175/65R14, and an S uses 185/60R15. Since both are radial fitments, the key decision is not bias-ply versus radial, but choosing a tire that matches the wheel, intended driving use, and the car's current setup.
Look closely at whether the car is still on its original wheel package or has been changed over time. A Yaris with replacement wheels, altered suspension height, or different wheel widths may need extra clearance and compatibility checks. For a stock-style replacement, staying with the correct trim-based size keeps the process much more straightforward.
How do I choose between the available 2009 Toyota Yaris tire sizes?
The two sizes for a 2009 Toyota Yaris are not alternative options for the same wheel package. The correct choice depends on the trim and wheel diameter: 175/65R14 for the Base and 185/60R15 for the S. Choosing between them is really a matter of identifying the right vehicle configuration first.
Once the trim and wheel size are confirmed, compare tires within that one size rather than moving across both fitments. That keeps mounting simple and helps preserve the dimensions intended for the wheel package on the car. If the Yaris has been modified, confirm wheel size and clearance before treating either fitment as a suitable replacement.
What rim-fitment details should I compare when choosing 2009 Toyota Yaris tires?
The most important rim-fitment detail on a 2009 Toyota Yaris is diameter. The Base uses a 14-inch setup with 175/65R14 tires, and the S uses a 15-inch setup with 185/60R15 tires. The tire must match the wheel diameter exactly, since the two Yaris sizes are built around different rims.
It also helps to inspect the wheel width and overall wheel condition before mounting new tires, especially on a car that has seen previous owner changes. Bent wheels, unusual aftermarket offsets, or mismatched replacements can affect how a tire sits and clears. A quick check now can prevent mounting the right tire size onto the wrong wheel package.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Toyota Yaris?
A period-style approach for a 2009 Toyota Yaris begins with the original trim-based tire size rather than with a vintage construction choice. The Base should stay with 175/65R14, and the S should stay with 185/60R15. Because both primary fitments are modern radial sizes, the goal is usually to preserve the car's intended everyday compact-car character.
For a clean, restoration-oriented result, match the correct size to the correct wheel package and avoid mixing Base and S fitments without confirming the wheels on the car. Owners who want a highly exact presentation should also compare present equipment against vehicle-specific references and surviving original examples before making appearance-driven changes.
Does correct tire fitment matter for a 2009 Toyota Yaris restoration?
Correct tire fitment matters because the 2009 Toyota Yaris used different sizes for different sub-models. A Base restored on 175/65R14 tires presents differently from an S on 185/60R15, and each setup belongs with its matching wheel diameter. Using the wrong combination can change the look of the car and complicate mounting.
Fitment accuracy also affects the overall impression of a finished restoration or preservation project. Even on a modern compact car, tire size influences stance, wheel-to-tire proportion, and how authentic the car appears to knowledgeable enthusiasts. Verifying the trim and wheel package before replacement helps keep the result visually consistent and mechanically sensible.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Toyota Yaris?
Yes, modifications can affect tire fitment on a 2009 Toyota Yaris even when the replacement tire size is one of the original trim-based sizes. Aftermarket wheels, changes in wheel width or offset, and suspension lowering can all alter how a 175/65R14 or 185/60R15 tire sits in the wheel opening and clears during steering movement.
A Yaris that no longer has its original wheel package should be checked carefully before replacement. Verify the actual wheel diameter, look at clearance around the strut, fender, and inner wheel well, and confirm that the tire size matches the wheel being used. Small cars can be especially sensitive to wheel and tire changes.
What should I inspect before driving a 2009 Toyota Yaris on new tires?
Before driving a 2009 Toyota Yaris on new tires, inspect that the installed size matches the wheel diameter and trim-based fitment. Then check inflation pressure, lug torque, valve stems, and basic clearance with the steering turned through its range. A quick visual check helps confirm the tire is seated properly and nothing is rubbing.
It is also smart to look over the rest of the wheel and suspension system while the tires are fresh. Uneven wear from the previous set, damaged wheels, weak shocks, or alignment issues can shorten tire life quickly. Catching those problems early helps the new tires wear more evenly and keeps the Yaris driving predictably.
How often should tires on a 2009 Toyota Yaris be inspected?
Tires on a 2009 Toyota Yaris should be inspected regularly rather than only when a problem appears. Monthly pressure checks are a good habit, and the tires should also be looked over for cuts, punctures, sidewall damage, uneven wear, and tread depth changes. Compact daily drivers can hide tire wear until it becomes more serious.
A closer inspection is especially useful before a longer trip or after hitting potholes or curbs. Owners should also pay attention to vibration, pulling, or visible air loss, since those signs can point to wheel damage or alignment issues. Regular checks matter whether the car uses the Base 14-inch setup or the S 15-inch package.
