The 2021 Hyundai Sonata sits in a part of the midsize sedan market where trim level matters as much as styling, especially once tire fitment enters the picture. Its sharp, modern bodywork and broad trim spread run from efficiency-focused hybrid models to the more aggressive N Line, so the right tire choice starts with confirming the exact version of the car. Tire sizing ranges from 205/65R16 up to 245/40R19, and every primary fitment here is radial. That means the decision is less about vintage construction choices and more about matching the correct rim diameter, profile, and product character to the way the Sonata is equipped and driven.
Which Tire Size Is Right for The 2021 Hyundai Sonata
The 2021 Hyundai Sonata uses four primary tire sizes, and they are tied directly to specific sub-models and wheel diameters. All of them are radial metric sizes, but the key difference is the exact wheel and trim combination, so the first step is confirming whether the car is on 16-, 17-, 18-, or 19-inch rims before comparing tire choices.
205/65R16 is a metric radial size in which 205 is the nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 16 is the rim diameter in inches. On the 2021 Hyundai Sonata, this size suits configurations built around a 16-inch wheel and a taller sidewall profile than the larger-wheel trims. Its practical appeal is a more traditional midsize-sedan tire proportion rather than the lower-profile look of the 18- and 19-inch fitments. This is the right size to evaluate only after confirming the car was equipped for the 16-inch wheel package.
215/55R17 is a metric radial size that uses a 215-millimeter nominal section width, a 55-series profile, and a 17-inch rim diameter. For the 2021 Hyundai Sonata, it covers several trims and sits between the smaller 16-inch setup and the more aggressive 18- and 19-inch packages. Available products in this size come from BFGoodrich in blackwall form across the g-Force Comp 2 AS and g-Force Phenom T/A series. It is the size to consider when the car has the 17-inch wheel package and the goal is choosing among the available radial product styles within that fitment.
235/45R18 is a metric radial size with a 235-millimeter nominal section width, a 45-series aspect ratio, and an 18-inch rim diameter. On the 2021 Hyundai Sonata, this size belongs to an 18-inch wheel configuration and carries a lower-profile look than the 16- and 17-inch alternatives. BFGoodrich offers this fitment in blackwall form across g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series, giving buyers more than one performance-oriented product direction. This size should be evaluated only after confirming the Sonata uses the 18-inch wheel setup rather than one of the other factory diameter groups.
245/40R19 is a metric radial size in which 245 is the nominal section width in millimeters, 40 is the aspect ratio, and 19 is the wheel diameter in inches. For the 2021 Hyundai Sonata, this is the largest primary fitment in the lineup and is tied to specific trims using a 19-inch wheel. BFGoodrich options in this size are blackwall radials offered in g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This fitment deserves careful wheel confirmation, since moving between Sonata trim levels can mean a completely different rim diameter rather than a simple tire-style change.
Tire fitment on the 2021 Hyundai Sonata varies by sub-model, and each trim is tied to a specific wheel diameter and tire size. Checking the exact sub-model matters before comparing products, because the Sonata range spans from 16-inch hybrid and SE fitments to 19-inch N Line and SEL Plus applications.

2021 Hyundai Sonata Hybrid Blue
The 2021 Hyundai Sonata Hybrid Blue uses the 205/65R16 radial size. That makes tire selection mainly a matter of staying with the correct 16-inch metric fitment and confirming the car has not been changed to a different wheel package.
The 2021 Hyundai Sonata Hybrid Limited uses the 215/55R17 radial size. Tire choice here starts with the 17-inch wheel fitment, then moves to comparing the available blackwall radial product series in that size.
The 2021 Hyundai Sonata Hybrid SEL uses the 215/55R17 radial size. Its fitment path matches other 17-inch Sonata trims, so the key step is verifying the wheel diameter and then selecting among the available radial options in that exact size.
The 2021 Hyundai Sonata Limited uses the 235/45R18 radial size. That places it on the 18-inch setup, where product choice becomes more about comparing tire series within the correct lower-profile fitment rather than sorting through multiple primary sizes.
The 2021 Hyundai Sonata N Line uses the 245/40R19 radial size. Because this trim sits on the 19-inch fitment, wheel confirmation is essential before purchase, especially if the car has seen any wheel or suspension changes.
The 2021 Hyundai Sonata SE uses the 205/65R16 radial size. Tire selection is straightforward so long as the car remains on its 16-inch wheel setup and has not been converted to a larger Sonata wheel package.
The 2021 Hyundai Sonata SEL uses the 215/55R17 radial size. That keeps the focus on choosing the right 17-inch radial product rather than deciding between different primary fitments.
The 2021 Hyundai Sonata SEL Plus uses the 245/40R19 radial size. Buyers should confirm the 19-inch wheel setup first, then compare the available blackwall radial series that match this lower-profile fitment.
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.

The most common 2021 Hyundai Sonata tire questions come down to trim-specific sizing, wheel diameter, and how to choose among the available radial products once the exact fitment is confirmed.
Tire Size & Fitment
What tire size fits a 2021 Hyundai Sonata?
A 2021 Hyundai Sonata can use 205/65R16, 215/55R17, 235/45R18, or 245/40R19, depending on the exact sub-model. All four are radial metric sizes, and each one corresponds to a specific wheel diameter rather than being interchangeable across the whole Sonata lineup.
The practical first step is identifying the exact trim and confirming the wheel diameter on the car. A Sonata SE or Hybrid Blue uses a different size than a Limited, N Line, or SEL Plus, so the tire decision starts with matching the trim and rim size before comparing brands or series.
What size rim does a 2021 Hyundai Sonata use?
The 2021 Hyundai Sonata uses 16-, 17-, 18-, and 19-inch rim diameters across its different sub-models. Those wheel diameters pair with 205/65R16, 215/55R17, 235/45R18, and 245/40R19 tire sizes respectively, so the tire and wheel diameter must match exactly.
Checking the actual wheel on the car matters because Sonata trim levels do not all share the same setup. A tire sized for a 17-inch rim cannot be mounted on an 18-inch wheel, so confirming the wheel diameter is more important than choosing a tread pattern or product series first.
Why does the 2021 Hyundai Sonata have more than one tire size?
The 2021 Hyundai Sonata has more than one tire size because different sub-models use different wheel packages. The range runs from 16-inch fitments on some efficiency-focused trims to 19-inch fitments on higher-spec or sportier versions, with each setup using its own matching tire size.
That means tire shopping for this Sonata is really trim-specific. A buyer should confirm the sub-model name, then verify the wheel diameter on the vehicle, especially if it was purchased used or may have aftermarket wheels. Once that is settled, comparing the correct size becomes much more straightforward.
Choosing the Right Tire
What should I consider when choosing a 2021 Hyundai Sonata tire?
Start with the exact tire size and rim diameter used by the specific 2021 Hyundai Sonata sub-model. This car uses four different metric radial sizes, so getting the correct 16-, 17-, 18-, or 19-inch fitment matters more than any product feature or brand preference.
After size is confirmed, compare construction details within the available products, including tire series, rim-width compatibility, and any load figures given for that size. It also helps to think about how the car is used, since a daily-driven Sonata may call for a different product character than one chosen mainly for appearance.
What brands offer tires for the 2021 Hyundai Sonata?
BFGoodrich offers available products for the 2021 Hyundai Sonata in the supported 17-, 18-, and 19-inch fitments. Within those sizes, the lineup includes g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series, all in radial blackwall form.
The more useful comparison is not brand-versus-brand, but which BFGoodrich series matches the specific size on the car. Once the correct Sonata trim and wheel diameter are confirmed, the buyer can compare series character, rim-width range, and other product details without drifting into the wrong fitment.
What tire series are available for the 2021 Hyundai Sonata?
Available 2021 Hyundai Sonata tire series include BFGoodrich g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A. Series availability depends on the tire size, with the 18- and 19-inch fitments offering the broadest spread of choices among the current products.
That makes the exact Sonata trim important even after the size is known. A 215/55R17 car has fewer series choices than a 235/45R18 or 245/40R19 car, so buyers should look at the product grid with the correct size in mind and compare only the tires that match that wheel package.
Restoration & Appearance
Does correct tire fitment matter for a 2021 Hyundai Sonata restoration?
Correct tire fitment still matters on a 2021 Hyundai Sonata, even though this is a modern vehicle rather than a traditional restoration-era car. The right metric radial size preserves the intended wheel-to-tire relationship for the specific trim, whether the car uses 16-, 17-, 18-, or 19-inch rims.
Appearance can change noticeably when profile and wheel diameter no longer match the original trim package. Anyone returning a used Sonata to stock-style presentation should confirm the exact sub-model, then verify the current wheels on the car, since previous owners sometimes change wheel packages in ways that alter the visual balance.
How does tire construction affect the appearance of a restored 2021 Hyundai Sonata?
On a 2021 Hyundai Sonata, construction choice is straightforward because the primary fitments are all radial. The appearance difference comes less from bias-ply versus radial concerns and more from using the proper metric size and sidewall profile for the trim, especially as wheel diameter increases from 16 to 19 inches.
A Sonata restored toward stock-style presentation looks most cohesive when the tire profile matches its original wheel package. Lower-profile 18- and 19-inch fitments create a different visual character than the taller 16-inch setup, so maintaining the correct size is usually the most important appearance decision on this model.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2021 Hyundai Sonata?
Yes, modifications can affect tire fitment on a 2021 Hyundai Sonata. Aftermarket wheels, changes in wheel width, suspension lowering, or alignment changes can alter the way a 205/65R16, 215/55R17, 235/45R18, or 245/40R19 tire sits in the wheel opening and clears surrounding components.
A Sonata that no longer has its original wheel package should be checked carefully before replacement tires are selected. Measuring the actual rim diameter and width, then inspecting fender and steering clearance, is especially important on the 18- and 19-inch setups where profile and wheel fitment are less forgiving.
What should I inspect before driving a 2021 Hyundai Sonata on new tires?
Before driving a 2021 Hyundai Sonata on new tires, inspect wheel condition, verify the correct tire size for the trim, and confirm inflation is set properly for the vehicle’s requirements. It is also wise to check for uneven wear patterns, visible damage, and any signs that alignment or suspension issues were affecting the previous tires.
A short road check after installation can reveal vibration, pull, or clearance issues that were not obvious at a standstill. Attention should also go to lug torque, valve condition, and whether the car still carries the wheel package that matches its original sub-model, since used Sonatas are sometimes fitted with different rims.
How often should tires on a 2021 Hyundai Sonata be inspected?
Tires on a 2021 Hyundai Sonata should be inspected regularly for tread wear, air loss, cuts, bulges, and sidewall damage. Even on a newer vehicle, routine checks matter because this Sonata uses several low-profile fitments, and those sizes can make visible condition and inflation more important to day-to-day road behavior.
Monthly pressure checks and visual inspections are a sensible habit, with closer attention before longer trips. It also helps to look for uneven wear that could point to alignment or suspension issues, especially if the car is on 18- or 19-inch wheels or has been changed from its original trim-specific setup.
