2009 Scion Tire Fitment Guide

2009 Scion vehicles use five model-specific tire sizes rather than one size shared across the full lineup. The tC uses 215/45R17 or 225/40R18, the xB uses 205/55R16 or 225/45R17, and the xD uses 195/60R16. Rim diameters therefore span 16, 17, and 18 inches depending on model and wheel package. Where product measurements are available, rim width ranges run from 5.5-7.5 inches for 205/55R16, 7.0-8.0 inches for 215/45R17, 7.0-8.5 inches and one 8.5-10.0-inch application for 225/45R17, and 7.5-9.0 inches for 225/40R18.

That spread means a 2009 Scion owner should identify the exact model before thinking about brands or tread patterns. A tC owner may still need to confirm whether the car is on 17-inch or 18-inch wheels, while an xB owner may need to confirm whether the vehicle carries the 16-inch or 17-inch package. The xD is simpler because it stays with one 16-inch size. Once the model and wheel diameter are confirmed, the search becomes much narrower and more accurate.

On a 2009 Scion tire, 215/45R17 is a modern metric radial size. The 215 is the nominal section width in millimeters, 45 is the aspect ratio, meaning the sidewall height is 45 percent of the section width, R indicates radial construction, and 17 is the wheel diameter in inches. For 2009 Scion fitment, that size belongs to the tC and mounts on a 17-inch wheel. Available examples are Blackwall radial tires from BFGoodrich with W speed ratings and published rim-width guidance of 7.0 to 8.0 inches.

That decoding matters because each part of the code affects what wheel the tire fits and how the tire fills the wheel opening. A buyer shopping for a 2009 Scion tC should not treat 215/45R17 as interchangeable with the tC’s 225/40R18 option just because both are performance-oriented radial sizes. The first one is tied to a 17-inch wheel and the second to an 18-inch wheel. Matching the full size code is more important than matching width alone.

No. 2009 Scion models do not share one universal tire size across the range. The tC uses 215/45R17 or 225/40R18, the xB uses 205/55R16 or 225/45R17, and the xD uses 195/60R16. Even when two models share a rim diameter, they do not share the same full tire size. The lineup includes 16-inch, 17-inch, and 18-inch fitments, all in radial construction.

That matters most when a buyer knows the car is a 2009 Scion but has not yet narrowed it to the exact model. A tC, xB, and xD have different proportions and different wheel packages, so shopping by year and make alone can easily send you to the wrong diameter or section width. The practical approach is to confirm the model badge, then confirm the wheel size already on the car, and only then compare brand, load, or speed details.

The available 2009 Scion tire options here are Blackwall radials across the covered sizes. That applies to 215/45R17 and 225/40R18 for the tC, 205/55R16 and 225/45R17 for the xB, and the available radial selections for those xB sizes come from BFGoodrich, Nitto, and Michelin depending on size. This fits the visual character of a 2009 Scion, since these cars were sold in a modern era when black sidewalls were the normal appearance for sporty and commuter-oriented compact cars.

For most 2009 Scion owners, that means appearance decisions are simpler than they would be on an older collector car where whitewalls or redlines might be part of the equation. The real choice shifts toward the correct size, wheel diameter, and the product’s load or speed characteristics rather than sidewall decoration. If the goal is a factory-like look, Blackwall is already aligned with the era. If the goal is a certain stance or driving feel, focus on the exact size and series instead.

BFGoodrich appears across every covered 2009 Scion size with multiple g-Force family options. Nitto is available in 225/40R18 for the tC and 225/45R17 for the xB, while Michelin appears in 205/55R16 for the xB. That means brand choice is broadest in the tC’s 18-inch and the xB’s 16- and 17-inch sizes, while the 17-inch tC size stays within the BFGoodrich range shown here.

A buyer can use that brand spread to narrow the search by driving style and by the exact wheel package on the car. Owners who already know they want BFGoodrich have coverage across the major tC and xB sizes, while shoppers comparing BFGoodrich against Nitto or Michelin need to start by confirming which size their car uses. Brand choice follows fitment, not the other way around. Once the size is settled, it becomes easier to compare series within that size.

For the 2009 Scion sizes where both appear, BFGoodrich g-Force Sport COMP-2 and BFGoodrich g-Force Phenom T/A share radial construction, Blackwall styling, and W speed ratings, but they differ in some published load figures and weights. In 215/45R17, the Sport COMP-2 carries a published max load of 1,201 pounds at 51 psi and weighs 23 pounds, while the Phenom T/A carries 1,356 pounds at 50 psi and weighs 23.55 pounds. In 225/40R18, the Sport COMP-2 is published at 1,235 pounds at 51 psi and 25 pounds, while the Phenom T/A carries 1,389 pounds at 50 psi and weighs 24.01 pounds.

Those differences do not change the basic fitment, but they do give a buyer another way to compare products once the correct size is confirmed. If you are narrowing down several BFGoodrich choices for a 2009 Scion tC or xB, details like published load capacity, exact weight, and the wheel-width range can help separate one series from another. The best approach is to compare those specifics within your size rather than trying to rank one series universally across the entire Scion range.

Rim-width guidance varies by size on 2009 Scion applications. 205/55R16 fits rims from 5.5 to 7.5 inches wide, 215/45R17 fits 7.0 to 8.0 inches, 225/40R18 fits 7.5 to 9.0 inches, and 225/45R17 generally fits 7.0 to 8.5 inches, with one 225/45R17 product also carrying an 8.5 to 10.0-inch recommendation. Those ranges are tied to the tire size itself, not to the full 2009 Scion lineup as a whole.

That means wheel diameter alone is not enough to confirm compatibility. A 17-inch wheel on a 2009 Scion tC and a 17-inch wheel on a 2009 Scion xB may still call for different tire sizes and different wheel-width ranges. Before choosing a tire, verify both the wheel diameter and the actual wheel width already on the car. Staying within the tire maker’s approved rim-width range helps preserve the intended shape and fit of the sidewall and tread.

2009 Scion tires are generally modern radial fitments, and tube status can vary by product. The clearest example is 205/55R16, where one Michelin option is marked TL, meaning tubeless, while the other products in that size do not all carry the same marking in the size description. The 215/45R17, 225/40R18, and 225/45R17 options shown here are modern radial performance-style tires and do not indicate tube-type construction in their size markings.

For a 2009 Scion owner, the practical takeaway is to check the exact sidewall marking on the tire you choose and to match it to the wheel condition and valve-stem setup on the car. These are not vintage split-rim or tube-era applications, so the question is usually product-specific rather than a trait of the vehicle itself. If one product is marked tubeless and another is not clearly marked the same way, use the tire’s own designation as the final guide.

A 2009 Scion stored with its tires fitted should be kept in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment. Tires last better when they are kept clean, properly inflated, and off damp ground. Moving the car periodically helps prevent flat spotting, especially if it sits for long stretches. If the vehicle will be parked for a season or more, using tire cradles or stands can reduce long-term stress on the casing.

That advice matters even more as 2009 Scion models move into low-mileage collector or hobby use. Modern radials hold up well, but long idle periods still age the rubber and can harden the tire before the tread is worn out. A car that looks fine at a glance may still develop vibration or cracking if it sits neglected. Good storage habits preserve both appearance and drivability and make the first drive back on the road much less eventful.

On a 2009 Scion, tire age usually matters more than mileage once the car becomes a lightly used second vehicle or weekend car. A sensible rule is to begin evaluating tires closely around five to seven years of age and to treat about ten years as the point where replacement deserves serious consideration regardless of remaining tread. The DOT date code on the tire sidewall gives the production week and year. Heat, storage conditions, and inflation history all affect service life.

That approach is especially useful for a 2009 Scion because many surviving examples are driven less than they were when new. A tire can still have good tread depth and yet be overdue because the rubber has aged out. Instead of judging by appearance alone, combine the date code with a close inspection for cracks, hardening, vibration, and pressure loss. If the age is advanced and the car is expected to see regular road use, replacement is usually the prudent call.

Tires on a 2009 Scion should be checked before every drive and given a more thorough inspection before any longer highway outing. Look for sidewall cracking, punctures, bulges, uneven wear, embedded debris, and signs of impact damage from potholes or curbs. Pressure should be checked when the tires are cold, and any tire that repeatedly loses air deserves immediate attention. Valve stems should also be inspected, since aging stems can fail even when the tread still looks acceptable.

That routine is easy to overlook on a compact car that feels modern compared with an older collector vehicle, but tire failures rarely give much warning. A quick walk-around catches many issues before they become roadside problems. On a 2009 Scion with sport-oriented sizes such as the tC’s 17- and 18-inch fitments, low-profile sidewalls also make curb or pothole damage worth taking seriously. Frequent inspection is one of the simplest ways to protect both the car and the driver.

Yes, the covered 2009 Scion tire sizes are modern radial designs with speed ratings appropriate for normal highway use. The 215/45R17, 225/40R18, and 225/45R17 options shown here are W-rated, which carries a 130 mph ceiling, and 205/55R16 includes W-rated options plus a Y-rated Michelin option with a 186 mph ceiling. Those ratings are well above ordinary U.S. highway speeds. In real-world driving, condition, age, inflation, and the car’s overall mechanical state matter more than the raw speed letter.

The important point is that a speed rating is not a license to drive at that number. A 2009 Scion owner should view it as an indicator that the tire was engineered for a certain sustained-speed capability under proper load and inflation. If the tires are old, underinflated, damaged, or mounted on the wrong wheel width, the rating becomes much less meaningful. For safe highway use, focus on fresh tires, correct pressure, and a full pre-drive inspection before worrying about top-end capability.

Inflation pressure on a 2009 Scion should follow the vehicle’s factory placard or owner’s manual for the original fitment, then be checked against the tire maker’s published limits for the specific replacement tire. Some 2009 Scion sizes here include max-load figures tied to pressure, such as 215/45R17 at up to 1,356 pounds at 50 psi, 225/40R18 at up to 1,389 pounds at 50 psi, 205/55R16 at up to 1,477 pounds at 50 psi, and 225/45R17 at up to 1,477 pounds at 50 psi. Those are maximum load-and-pressure references, not default everyday inflation settings.

That distinction is critical because everyday operating pressure is chosen around the vehicle, not simply the tire’s maximum sidewall figure. A lighter xD, a taller xB, and a sportier tC can all need different cold pressures even when tire sizes appear close on paper. Use the factory recommendation as the baseline, check pressure when the tires are cold, and adjust only within the tire maker’s approved limits. Never transfer a pressure figure from one 2009 Scion size to another just because both are radial tires.

Before a longer drive in a 2009 Scion, inspect each tire for cuts, bulges, cracking, punctures, and uneven wear, then set cold pressures correctly and confirm the valve stems are in good condition. Make sure tread depth is still appropriate for wet-road use and check the spare as well, including its age and inflation. On cars using lower-profile sizes such as 215/45R17 or 225/40R18, look carefully for wheel or sidewall damage from past pothole impacts.

Tires are only one part of the checklist, but they are the part in constant contact with the road. A longer trip is also a good time to inspect brakes, lights, fluids, and suspension condition, especially on a car that may sit between outings. For a 2009 Scion that has spent time as a commuter and later as a hobby car, that transition to less frequent use can hide age-related issues. A thorough pre-trip check turns a routine drive into a much more dependable one.
