2014 Scion Tire Fitment Guide

2014 Scion vehicles use seven sizes across five models: the FR-S uses 215/45R17, the iQ uses 175/60R16, the tC uses 225/45R18 or 235/35R19, the xB uses 205/55R16 or 225/45R17, and the xD uses 195/60R16. Rim diameters span 16, 17, 18, and 19 inches across the full Scion lineup. Rim width guidance is available for several of the active product sizes, including 16-, 17-, 18-, and 19-inch applications, and it varies by size rather than by make alone.

That spread means a 2014 Scion owner should identify the exact model first and then verify the wheel diameter currently on the car. The tC and xB especially deserve that extra check because each was offered with two different tire sizes tied to two different wheel diameters. Once the model and wheel size are confirmed, the remaining choice is usually among brands, speed ratings, and product character within that one correct size.

On a 2014 Scion, 215/45R17 is a modern metric radial size. The 215 is the nominal section width in millimeters, 45 is the aspect ratio, the R denotes radial construction, and 17 is the wheel diameter in inches. In the 2014 Scion range, that size belongs to the FR-S. Available versions use Blackwall styling and W speed ratings, with some products carrying load figures up to 1,356 pounds at 50 psi.

That decoding matters because it tells you far more than overall appearance. A 215/45R17 tire is built for a specific wheel diameter and sidewall profile, so it cannot be substituted casually with another Scion size that happens to look close. FR-S owners should treat 215/45R17 as the correct starting point, then compare product details such as brand, load figure, and recommended rim-width range before settling on the exact tire.

No, 2014 Scion models do not use the same tire size. The FR-S, iQ, and xD each use one distinct size, while the tC and xB each use two possible sizes tied to different wheel packages. Even the models that share a wheel diameter do not necessarily share a tire size; for example, the iQ, xB, and xD all appear in 16-inch applications, but each uses a different metric size.

That matters because year and make alone are not enough to choose a tire for a 2014 Scion. If you own a tC or xB, confirm whether the car has the smaller or larger wheel setup before comparing products. If you own an iQ, xD, or FR-S, the size path is simpler, but it is still smart to read the sidewall on the car now and match that to the model-specific fitment before moving ahead.

2014 Scion tires in the active product range come in Blackwall form across the supported sizes. That applies to the FR-S 215/45R17, tC 225/45R18 and 235/35R19, and xB 205/55R16 and 225/45R17 applications. The overall look is appropriate for a modern import lineup from the 2010s, where black sidewalls were the expected visual treatment rather than wide whitewalls or vintage specialty styling.

For most owners, that means the appearance decision is simple and the more meaningful comparison is between tire series, speed rating, and wheel-package compatibility. A Blackwall design keeps the car visually close to its original market character whether you drive an FR-S coupe or an xB hatchback. If appearance matters as much as performance, compare the tire’s tread and sidewall branding details within the correct size instead of searching for alternate sidewall treatments.

BFGoodrich, Nitto, and Michelin cover the active 2014 Scion applications here, depending on size. BFGoodrich appears across the FR-S 215/45R17, tC 225/45R18, tC 235/35R19, xB 205/55R16, and xB 225/45R17 sizes. Nitto appears in 225/45R18, 235/35R19, and 225/45R17, while Michelin appears in 205/55R16. All of those products are radial designs matched to Scion’s modern metric fitments.

Brand choice becomes more important after you have confirmed the exact tire size on your specific 2014 Scion model. Some sizes have one-brand coverage, while others let you compare BFGoodrich against Nitto or Michelin in the same basic fitment. That can influence speed rating, load figure, and rim-width compatibility, so a buyer should treat brand as a second-step decision after the model and wheel diameter are settled.

For the 2014 Scion tC in 225/45R18, BFGoodrich g-Force Comp-2 A/S and Nitto NT555 G2 share the same basic size, radial construction, Blackwall styling, XL designation, and W speed rating. The BFGoodrich tire fits a 7.0- to 8.5-inch rim-width range, while the Nitto tire also centers on that span and calls out 7.5 inches within the range. Nitto shows a max load of 1,521 pounds at 50 psi, and the BFGoodrich alternatives in this size also reach 1,521 pounds at 50 psi on several versions.

For a tC owner, that means the choice is less about fitment and more about the specific product family you prefer within the same 18-inch package. Both stay within the same overall sizing intent, so the smarter comparison is recommended wheel width, load figure, and the tread personality you want from one performance-oriented radial to another. Confirm the wheel width on the car before narrowing between the two.

Rim-width guidance varies by tire size on 2014 Scion applications. The 215/45R17 FR-S fitment runs on 7.0- to 8.0-inch rims. The 225/45R18 tC fitment commonly spans 7.0 to 8.5 inches, the 235/35R19 tC fitment reaches 8.0 to 9.5 inches, the 205/55R16 xB fitment spans 5.5 to 7.5 inches, and the 225/45R17 xB fitment generally falls in the 7.0 to 8.5 range, with one product extending wider.

Those ranges are a useful checkpoint before choosing a tire, especially if your 2014 Scion is running aftermarket wheels. Staying within the recommended rim-width span helps preserve the tire’s intended profile and mounting behavior. If the wheel width on the car sits near the edge of the range, compare the exact product you want rather than assuming every tire in the same size has identical wheel-width guidance.

2014 Scion tires are modern radial applications, and tube status can vary by product depending on the size. In 205/55R16 for the xB, at least one Michelin option is clearly marked TL for tubeless service, while the other active sizes do not show a tube-type marking here. That points the 2014 Scion range toward modern tubeless-style fitments rather than vintage tube-type practice, but the exact sidewall marking still matters.

The practical step is to match the tire, wheel, and valve setup as a system instead of assuming every 2014 Scion product is identical. If your car still has original-style wheels, inspect bead condition and valve stems before installation. If the product sidewall or product description includes a tube-related marking, follow that specific guidance and avoid carrying over assumptions from another Scion size or brand.

No, the original 2014 Scion wheels cannot be treated as universal across all seven tire sizes because the lineup uses 16-, 17-, 18-, and 19-inch diameters. A 17-inch FR-S or xB wheel cannot accept an 18- or 19-inch tC tire, and a 16-inch iQ, xB, or xD wheel cannot accept a 17-inch tire. Rim-width recommendations also change by size, so diameter alone is not the only consideration.

That makes wheel verification one of the most important steps before ordering replacement tires for a 2014 Scion. Read the tire sidewall that is currently on the car, confirm the wheel diameter, and compare the wheel width if it is known. Owners of xB and tC models should be especially careful, since both models appear with more than one factory-style size and that can create confusion when a car has changed hands.

A 2014 Scion should be stored in a cool, dry space away from direct sunlight, electric motors, battery chargers, welders, and other ozone-producing equipment that can accelerate rubber aging. Keep the tires clean, set them to a sensible storage pressure, and avoid leaving the car parked for very long periods on one contact patch if possible. Modern radials generally tolerate storage better than older bias-ply designs, but they still age from heat, light, and static load.

For a collector-owned or low-use 2014 Scion, the simplest routine is to move the car periodically or place it on stands if it will sit for an extended season. That helps reduce temporary flat-spotting and stress at one point on the sidewall. A breathable car cover and a clean floor also help, but the biggest gains come from controlling sunlight, ozone, and long uninterrupted periods of weight on the tires.

Tires on a 2014 Scion should be judged by age as much as by tread depth, especially on cars that are driven lightly. A common collector-car standard is to begin evaluating tires closely around five to seven years of age and to treat roughly ten years as a serious replacement threshold regardless of remaining tread. The DOT date code on the sidewall is the quickest way to confirm age.

That approach matters because many sport-compact and enthusiast cars, including some 2014 Scion models, do not accumulate enough miles to wear out tires before the rubber hardens and ages. A tire can still look presentable and have usable tread while no longer offering the flexibility and security it had when new. Check the date code, look for surface cracking, and make age part of every replacement decision.

Tires on a 2014 Scion deserve a quick inspection before every drive and a more careful inspection before any longer trip. Look for sidewall cracking, nails, cuts, bulges, irregular shoulder wear, and pressure loss. On the sizes where tubeless service is clearly marked, inspect the valve stem and bead area as well, since slow leaks there can mimic a tire problem.

Regular inspection is especially important on a car that alternates between short local drives and occasional highway use. A few minutes spent checking pressure and visual condition can reveal problems that would otherwise appear only after the tire has heated up on the road. If the car has been stored for a while, drive slowly at first and pay attention to vibration, pull, or pressure loss before committing to a longer outing.

2014 Scion tires in these applications are modern radial designs, and the active products carry speed ratings that are well beyond normal U.S. highway use. W-rated versions are rated to 168 mph, and the 235/35R19 application also includes a Y-rated option rated for 186 mph and above. In practical terms, the tires are not the limiting factor at ordinary highway speeds; vehicle condition, alignment, suspension health, and brake condition matter just as much.

Safe highway use on a 2014 Scion comes down to choosing the correct size, mounting it on the proper wheel width, maintaining pressure, and making sure the rest of the car is road-ready. A high speed rating should not be treated as permission to ignore age or condition. Even a performance-rated radial needs to be inspected for cracking, damage, and proper inflation before regular highway service.

Inflation pressure for a 2014 Scion should start with the vehicle manufacturer’s recommendation for the exact model and tire size, then be checked against the tire maker’s own rating information. Several of the active products show maximum load and pressure figures such as 1,201 pounds at 51 psi for 215/45R17, 1,521 pounds at 50 psi for 225/45R18, 1,356 pounds at 50 psi for one 235/35R19 option, 1,356 to 1,477 pounds at 50 to 51 psi for 205/55R16, and up to 1,477 pounds at 50 psi for 225/45R17.

Those figures are not automatic daily-use pressure recommendations for every 2014 Scion. They are maximum-rated reference points for the tire itself, and the correct operating pressure for your car may be lower depending on the model, axle load, and intended use. Use the door-jamb or owner’s-manual recommendation as the baseline, then verify that the tire’s own pressure limits and load capacity are appropriate for the application.

Before a longer drive in a 2014 Scion, inspect all four tires and the spare for tread condition, cuts, embedded debris, bulges, and visible age cracking. Confirm cold inflation pressures, check the valve stems, and look for any sign of uneven wear that could point to alignment or suspension issues. On models with staggered-looking wheel packages or multiple factory-size possibilities like the tC and xB, also make sure the tires on the car match the wheel diameter and intended fitment.

That tire check should be part of a broader road-readiness routine on any older or enthusiast-kept car. Verify fluids, brakes, lights, and battery condition at the same time so the tire inspection is not happening in isolation. If the car has been sitting, drive a short local loop first and recheck pressures afterward. A calm pre-trip inspection is usually enough to catch the small issues that become major interruptions on the highway.
