The 2016 Scion iA arrived as a compact sedan aimed at drivers who wanted efficient, straightforward transportation with a more engaging feel than many economy cars of its era. Its light footprint and modern chassis make tire condition and fitment especially important to the way the car rides, steers, and tracks on the road. This model uses one primary tire size, 185/60R16, in radial construction on a 16-inch rim. Because the fitment is simple and consistent, the real choice is finding the right tire within that size and confirming wheel compatibility if the car has been changed from stock. That matters whether the goal is daily driving, careful upkeep, or replacing aging original-style fitment with confidence.
Which Tire Size Is Right for The 2016 Scion iA
The 2016 Scion iA uses one primary tire size: 185/60R16, a modern metric radial built for a 16-inch rim. That same size applies to the covered Base sub-model, so the main decision is not between multiple factory fitments, but whether the car still has the correct wheel setup and whether the replacement tire suits its intended road use and overall condition.
The size 185/60R16 is a metric radial designation: 185 is the nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 16 is the wheel diameter in inches. On the 2016 Scion iA, this modern radial format matches the car's straightforward compact-sedan fitment and keeps tire selection centered on one clearly defined size. Because the sizing is contemporary and widely understood, the important details shift to tire quality, wheel compatibility, and the condition of the suspension and alignment. It is the right starting point for owners who want to preserve the intended fitment without introducing unnecessary sizing changes.
Sub-model fitment is straightforward for the 2016 Scion iA. The covered sub-model uses the same primary tire size, so tire selection is mainly about confirming the car still wears the correct 16-inch wheel setup and choosing an appropriate replacement within that size.

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 2016 Scion iA tire size, 16-inch rim fitment, choosing the right 185/60R16 radial tire, and the basic checks that matter before regular driving or after wheel and suspension changes.
Tire Size & Fitment
What tire size fits a 2016 Scion iA?
The 2016 Scion iA uses 185/60R16 tires. This is a metric radial size, and it is the primary fitment for the model covered here, including the Base sub-model.
That makes sizing more straightforward than on vehicles with multiple factory tire options. The main thing to verify is that the car still has the correct 16-inch wheels and has not been changed to a different wheel or tire package. If aftermarket wheels, suspension changes, or non-stock tires are already on the car, confirm wheel diameter, width, and clearance before replacing anything.
What size rim does a 2016 Scion iA use?
The 2016 Scion iA uses a 16-inch rim with its 185/60R16 tire size. The final number in the tire size, 16, is the wheel diameter in inches and must match the rim diameter.
Rim diameter is the first fitment check because a 16-inch tire cannot be mounted on a wheel of another diameter. It is also worth confirming the actual wheel setup on the car, especially if it has had replacement wheels installed over time. Wheel width and offset also influence how the tire seats and clears the suspension and fenders, even when the rim diameter is correct.
Does the 2016 Scion iA Base use the same tire size?
Yes. The 2016 Scion iA Base uses the same 185/60R16 radial tire size as the core model. There is no separate primary size to sort through for the covered sub-model.
That consistency helps simplify replacement shopping, since the main question is usually tire choice within the correct size rather than which size belongs on the car. Even so, it is smart to look at the wheels currently installed before ordering replacement tires. A previous owner may have changed the wheel package, and the car should always be matched to its actual wheel diameter and overall clearance conditions.
Choosing the Right Tire
What should I consider when choosing a 185/60R16 tire for a 2016 Scion iA?
Start with the correct size, 185/60R16, and make sure the tire is intended for a 16-inch wheel. From there, the most important factors are overall fitment, construction consistency, and whether the tire suits how the 2016 Scion iA is actually used.
A daily-driven car may prioritize stable road manners and predictable wear, while a lightly used example may need extra attention to age and condition more than tread depth alone. It also helps to confirm the car's alignment, wheel condition, and suspension health before replacement. Even the right size can feel disappointing if worn components or previous modifications are affecting how the tire sits and works.
How do I choose between the available 185/60R16 tires for a 2016 Scion iA?
The best way to compare 185/60R16 tires for a 2016 Scion iA is to begin with fitment, then narrow the choice by intended use and the car's current condition. Staying with the correct size protects the basic relationship between tire, wheel, and chassis.
Once size is settled, compare practical details such as how often the car is driven, whether it sees mostly city or highway use, and whether the suspension and alignment are in good order. A car that is only used occasionally can still need fresh tires if the existing set has aged out. Choosing carefully means looking beyond tread pattern and making sure the whole setup is ready for the road.
What rim-fitment details should I compare when choosing 2016 Scion iA tires?
For a 2016 Scion iA, the first rim-fitment detail is diameter: the tire size 185/60R16 requires a 16-inch wheel. That match is non-negotiable, since tire and wheel diameter must be the same.
After diameter, check the actual wheel width and offset on the car, especially if the wheels are not original to the vehicle. Those details affect how the tire sits, how close it runs to suspension components, and whether it clears the fenders through normal steering and suspension travel. Looking at the complete wheel setup helps avoid replacing the tire while overlooking the reason the current fitment may already be compromised.
Restoration & Appearance
Does correct tire fitment matter for a 2016 Scion iA restoration or preservation project?
Yes. Even on a newer collector-minded or well-preserved car, correct tire fitment matters because the tire size influences stance, ride quality, steering response, and the overall visual balance of the vehicle. For the 2016 Scion iA, that starting point is 185/60R16 on a 16-inch rim.
Owners focused on preservation should avoid assuming that any tire close in appearance will maintain the same fitment relationship. The safer approach is to confirm the car still uses the intended wheel diameter and an appropriate wheel width before replacement. Keeping the sizing consistent also makes it easier to evaluate how the car looks and drives without introducing unrelated changes from a mismatched wheel and tire package.
Which tire should I choose for a well-kept 2016 Scion iA?
For a well-kept 2016 Scion iA, the right place to begin is the original fitment size, 185/60R16. That keeps the car aligned with its intended wheel diameter and preserves the overall proportions that suit the chassis.
The better choice is usually the one that respects the car's actual condition and use rather than chasing a different size for appearance alone. A low-mileage example still needs attention to tire age, sidewall condition, and evenness of wear. When presentation matters, keeping the fitment consistent and the wheels in proper shape usually does more for the car's appearance than experimenting with alternate sizes.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2016 Scion iA?
Yes. Modifications can change tire fitment on a 2016 Scion iA even when the tire size remains 185/60R16. Aftermarket wheels, different wheel offsets, suspension changes, or lowering can all alter clearance and how the tire sits in the wheel opening.
That is why the current setup should be checked before replacing tires, rather than assuming the car still matches its original wheel arrangement. Look at steering clearance, fender clearance, and the relationship between the tire and nearby suspension components. A fitment that seems acceptable at rest can become a problem under turning, braking, or full suspension movement if the wheel package has been changed.
What should I inspect before driving a 2016 Scion iA on new tires?
Before driving a 2016 Scion iA on new tires, inspect the wheels for damage, confirm proper tire pressure, and make sure the tires are mounted in the correct 185/60R16 size. It is also wise to check alignment condition and look for suspension wear that could affect tire behavior.
A fresh set of tires cannot correct underlying mechanical problems. Uneven wear, pulling, vibration, or poor tracking can continue if worn shocks, bushings, or alignment issues are still present. It also helps to recheck lug torque after installation and keep an eye on air pressure during the first several drives. Early attention often catches a mounting or vehicle-condition issue before it becomes a larger problem.
How often should tires on a 2016 Scion iA be inspected?
Tires on a 2016 Scion iA should be inspected regularly, not just when tread looks low. A quick visual check before routine driving and a more careful inspection at service intervals helps catch uneven wear, cuts, bulges, sidewall cracking, and slow air loss.
Frequent inspection matters even more on a car that is driven infrequently, because age and storage conditions can affect tires long before tread is worn out. Watch for changes in ride quality or steering feel, and look at all four tires rather than only the front pair. Catching pressure loss, aging, or abnormal wear early is one of the simplest ways to protect both tire life and road manners.
