The 2009 Scion tC sits in the sport-compact era that made coupe styling, sharp handling, and personalization central to the ownership experience. As a two-door model with strong appeal among daily drivers and enthusiasts alike, the tC often lives somewhere between practical commuter and lightly modified street car. Tire fitment centers on two radial sizes, 215/45R17 and 225/40R18, so the first step is confirming which wheel package is on the car. From there, the real choice is among blackwall performance-oriented radial options in different series and brands. That matters whether the goal is preserving the car’s intended stance, matching an upgraded wheel setup, or refreshing a driver-focused street coupe.
Which Tire Size Is Right for The 2009 Scion tC
The 2009 Scion tC uses two primary tire sizes, and the correct one depends on which wheel diameter is on the car. Both fitments are radial, but one is built for a 17-inch rim and the other for an 18-inch rim, so confirming the actual wheel package comes first before comparing brands, series, or other tire details.
215/45R17 is a modern metric radial size in which 215 identifies nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 17 is the wheel diameter in inches. On the 2009 Scion tC, this size supports the car’s modern sport-compact fitment with a 17-inch wheel. Available choices include BFGoodrich options in the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series, all in blackwall form. This size is the one to evaluate when the car retains its 17-inch setup and the decision shifts to driving character, series choice, and wheel-width compatibility.
225/40R18 is a modern metric radial size where 225 is the nominal section width in millimeters, 40 is the aspect ratio, R marks radial construction, and 18 identifies the wheel diameter in inches. For the 2009 Scion tC, this fitment belongs with an 18-inch wheel and gives the buyer a different wheel-and-tire package to confirm before selecting a tire. Product choices include blackwall offerings from BFGoodrich and Nitto across the g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 lines. This is the size to compare when the car is already on 18-inch rims and you want to match that setup correctly.
The 2009 Scion tC Base is straightforward in name but still requires a wheel check because it can use more than one tire size. Tire selection depends less on trim identification than on confirming whether the car is fitted with 17-inch or 18-inch wheels.

2009 Scion tC Base
The 2009 Scion tC Base uses radial tire fitments tied to two wheel packages rather than a single universal size. That makes wheel-diameter confirmation the key step, after which the choice becomes selecting the right blackwall tire series and brand for the car’s actual 17-inch or 18-inch setup.
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.
Best 2009 Scion tC Tires for Sale
Available 2009 Scion tC tires focus on radial blackwall performance choices in 215/45R17 and 225/40R18. BFGoodrich covers both sizes across several g-Force series, while 225/40R18 also adds a Nitto NT555 G2 option, giving buyers meaningful differences in series, brand, and wheel-width range.
These 2009 Scion tC tire FAQs focus on the two correct sizes, 17-inch versus 18-inch wheel fitment, available radial choices, and the practical checks that matter before putting the car back into regular road use.
Tire Size & Fitment
What tire size fits a 2009 Scion tC?
The 2009 Scion tC uses two primary tire sizes: 215/45R17 and 225/40R18. Both are radial fitments, and the correct one depends on the wheel package installed on the car rather than a change in basic construction type.
The practical first step is checking the wheel diameter on the vehicle, because a 17-inch tire cannot be mounted on an 18-inch wheel and vice versa. Once the wheel size is confirmed, the choice moves to comparing available tire series, brand options, and wheel-width compatibility within that exact size.
What size rim does a 2009 Scion tC use?
A 2009 Scion tC uses either a 17-inch or 18-inch rim, depending on which of its two tire sizes is on the car. The 215/45R17 fitment uses a 17-inch rim, while the 225/40R18 fitment uses an 18-inch rim.
That rim diameter should be confirmed directly on the wheel or from the tire already mounted on the car before choosing replacements. Buyers should also verify actual wheel width if the car has aftermarket wheels, since compatible rim-width ranges vary between the available 17-inch and 18-inch tire options.
Why does the 2009 Scion tC have more than one tire size?
The 2009 Scion tC has more than one tire size because it can be found with two different wheel diameters. Its tire fitment is split between 215/45R17 on a 17-inch rim and 225/40R18 on an 18-inch rim, both in radial construction.
That means the right choice is determined by the wheel setup on the individual car, not by guessing from the model name alone. A tC that has been modified or fitted with replacement wheels should be checked carefully so the selected tire matches the actual rim diameter and intended wheel-width range.
Choosing the Right Tire
What should I consider when choosing a 2009 Scion tC tire?
Start with the exact tire size and wheel diameter on the car, since the 2009 Scion tC uses either 215/45R17 or 225/40R18. Both are radial fitments, so the next comparison points are brand, tire series, sidewall style, and the rim-width range that matches the wheel.
From there, think about how the car is actually used. A daily-driven tC, a lightly modified street car, and a seasonal fun car may all lead buyers to different series choices even within the same size. Matching the tire to the car’s wheel setup and intended use matters more than choosing by name alone.
What sidewall styles are available for 2009 Scion tC tires?
The available 2009 Scion tC tire choices in both 215/45R17 and 225/40R18 are blackwall radials. That gives the car a clean modern sport-compact appearance rather than a vintage-style sidewall treatment such as whitewall, redline, or raised white letter.
For most tC owners, that keeps the decision centered on size, tire series, and brand instead of sidewall appearance. It is still worth checking the product details closely, especially if the car has a specific styling direction or wheel design, because sidewall presentation can affect the overall look even within blackwall-only choices.
What brands offer tires for the 2009 Scion tC?
BFGoodrich and Nitto both offer tire choices for the 2009 Scion tC, though coverage differs by size. BFGoodrich appears in both 215/45R17 and 225/40R18, while Nitto is available in the 225/40R18 fitment through the NT555 G2 line.
Brand alone should not be the only filter. Buyers should compare the exact series available in the needed size, along with wheel-width compatibility and any load information tied to the product. That approach keeps the selection focused on the car’s actual setup instead of assuming every brand offers the same fitment range.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Scion tC?
A period-style 2009 Scion tC usually starts with keeping the correct wheel diameter and matching the tire size already intended for that setup, either 215/45R17 or 225/40R18. Since the available choices are all blackwall radials, the appearance decision is more about maintaining the car’s sport-compact look than recreating an older sidewall style.
Series choice can still influence the overall presentation, especially on a clean, well-kept tC that is meant to reflect its late-2000s character. Buyers focused on originality should compare the car’s current wheels and visual goals carefully, particularly if the vehicle has changed hands or has already been modified from its earlier configuration.
Does correct tire fitment matter for a 2009 Scion tC restoration?
Correct tire fitment matters on a 2009 Scion tC restoration because the car’s stance, wheel proportion, and road manners all depend on using the proper size for the wheel package in place. On this model, that means staying with either 215/45R17 or 225/40R18 rather than treating the two sizes as interchangeable.
Appearance is part of that decision, but fitment accuracy is just as important. A restored or refreshed tC should have its wheel diameter verified first, then its wheel width and overall clearance checked if anything has been changed. That keeps the tire choice consistent with the car’s setup instead of relying on visual guesswork.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Scion tC?
Yes, modifications can affect tire fitment on a 2009 Scion tC. Aftermarket wheels, suspension changes, lowering, or body alterations can change the space available around a 215/45R17 or 225/40R18 tire, and they can also alter which rim width works best.
A tC that no longer has its original wheel setup should be checked closely before replacement tires are chosen. Wheel diameter, actual wheel width, and clearance at the fender, strut, and steering range all matter. That is especially important when the car has 18-inch wheels or a modified stance intended to tighten wheelwell appearance.
What should I inspect before driving a 2009 Scion tC on new tires?
Before driving a 2009 Scion tC on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure the tires are inflated properly for the vehicle’s needs. It is also smart to look over the suspension and alignment condition so the new tires start service on a sound platform.
A short local test drive is useful for checking vibration, rubbing, or steering issues before putting the car into heavier use. Any tC with aftermarket wheels or suspension changes deserves extra attention, since even the correct nominal tire size can behave differently when wheel width, ride height, or clearance has changed.
How often should tires on a 2009 Scion tC be inspected?
Tires on a 2009 Scion tC should be inspected regularly, not just when tread looks worn. Pressure, uneven wear, sidewall damage, punctures, and signs of aging can all develop gradually, especially on a car that sees mixed use between commuting, weekend driving, and longer highway trips.
Monthly checks are a sensible habit, and the tires should also be looked over before any longer drive. Cars that sit for stretches still need attention because low use does not prevent aging or air loss. Keeping the inspection routine consistent helps protect both ride quality and the service life of the correct 17-inch or 18-inch fitment.
