The 2020 Hyundai Sonata marked a major styling shift for Hyundai’s midsize sedan, pairing a more dramatic body shape with trim-specific wheel and tire packages that change the fitment story from one version to another. For this Sonata, the primary tire question starts with identifying the exact sub-model, because fitment ranges from 205/65R16 to 235/45R18 and all three sizes use radial construction. That also means the buying decision can move beyond simple size confirmation into wheel diameter, tread character, and available performance-oriented product choices in the larger sizes. Whether the goal is everyday road use or keeping the car true to its intended trim character, matching the tire to the correct setup comes first.
Which Tire Size Is Right for The 2020 Hyundai Sonata
The 2020 Hyundai Sonata uses three different tire sizes, and the correct one depends on the specific sub-model and wheel diameter. All three are radial metric sizes, but they are tied to different 16-inch, 17-inch, and 18-inch wheel setups. Before choosing a tire, confirm the exact Sonata trim and the actual wheel diameter currently on the car, especially if the vehicle has had wheels changed since new.
205/65R16 is a metric radial size in which 205 identifies the nominal section width in millimeters, 65 is the aspect ratio, R indicates radial construction, and 16 is the rim diameter in inches. On the 2020 Hyundai Sonata, this size serves trims equipped with the 16-inch wheel package and keeps the fitment in a conventional modern sedan format. Product selection details are more limited here than in the larger Sonata sizes, so the main focus is staying with the correct dimensions and wheel match. This size is the right place to start when the car is a 16-inch Sonata configuration rather than a 17-inch or 18-inch setup.
215/55R17 is a metric radial size that measures 215 millimeters in nominal section width, uses a 55-series profile, and fits a 17-inch rim. For the 2020 Hyundai Sonata, this size belongs to specific trims built around the 17-inch wheel package, making wheel confirmation just as important as trim identification. Available choices in this size include BFGoodrich blackwall radials across the g-Force Comp 2 AS and g-Force Phenom T/A series. It is a useful size for buyers who want to stay with the proper 17-inch Sonata fitment while comparing tire series and rim-width compatibility within that package.
235/45R18 is a metric radial size with a 235-millimeter nominal section width, a 45-series profile, and an 18-inch rim diameter. On the 2020 Hyundai Sonata, this size is tied to trims using the largest wheel package, so it should not be treated as a universal Sonata fitment. In this size, BFGoodrich offers blackwall choices in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines, giving buyers meaningful series differences within the correct dimensions. This size makes the most sense when the car is already equipped with the proper 18-inch wheels and the owner wants to preserve that trim-level setup.
Tire fitment varies across the 2020 Hyundai Sonata lineup, so choosing a tire starts with confirming the exact sub-model. The difference is not just the tire size itself, but also the wheel diameter that goes with each trim.

2020 Hyundai Sonata Hybrid Blue
The 2020 Hyundai Sonata Hybrid Blue uses the 205/65R16 radial tire size on a 16-inch wheel setup. Tire selection here is mainly about staying with the correct 16-inch dimensions and confirming that the car has not been changed to a different wheel package.
The 2020 Hyundai Sonata Hybrid Limited uses the 215/55R17 radial size. That places it in the 17-inch Sonata fitment group, where product choice can include different BFGoodrich tire series while keeping the correct overall package for this sub-model.
The 2020 Hyundai Sonata Hybrid SEL also uses the 215/55R17 radial size. That makes wheel-diameter confirmation straightforward, and the next decision becomes comparing available blackwall radial choices within the proper 17-inch fitment.
The 2020 Hyundai Sonata Limited uses the 235/45R18 radial size with an 18-inch wheel package. Tire shopping for this sub-model should center on preserving the correct 18-inch fitment and comparing the available performance-oriented series in that size.
The 2020 Hyundai Sonata SE uses the 205/65R16 radial size. For this trim, the important step is confirming that the car still carries its 16-inch wheel setup before moving on to any replacement tire decision.
The 2020 Hyundai Sonata SEL uses the 215/55R17 radial tire size. That keeps selection focused on the correct 17-inch fitment, with room to compare available radial series rather than sorting through multiple constructions.
The 2020 Hyundai Sonata SEL Plus uses the 235/45R18 radial size. Because this trim shares the larger 18-inch wheel package, tire choice should start with that wheel confirmation and then move to comparing the available blackwall tire series.
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 2020 Hyundai Sonata tire questions come down to trim-specific size fitment, wheel diameter, and choosing among the available radial options in the 17-inch and 18-inch sizes. These answers also cover maintenance and setup checks before road use.
Tire Size & Fitment
What tire size fits a 2020 Hyundai Sonata?
The 2020 Hyundai Sonata uses three tire sizes: 205/65R16, 215/55R17, and 235/45R18. All are radial sizes, and the correct one depends on the specific Sonata sub-model. SE and Hybrid Blue use 205/65R16, SEL, Hybrid SEL, and Hybrid Limited use 215/55R17, while Limited and SEL Plus use 235/45R18.
That makes trim identification the first step before choosing a replacement tire. It also helps to confirm the actual wheel diameter on the car, because a Sonata that has been fitted with different wheels may no longer match its original trim-based setup. Using the right size starts with matching both the sub-model and the wheel package.
What size rim does a 2020 Hyundai Sonata use?
The 2020 Hyundai Sonata uses three rim diameters depending on sub-model: 16-inch, 17-inch, and 18-inch. The 205/65R16 tire fits a 16-inch rim, 215/55R17 fits a 17-inch rim, and 235/45R18 fits an 18-inch rim. Each tire size is built around its own wheel diameter rather than being interchangeable across all Sonata trims.
Wheel diameter should be confirmed before ordering tires, especially on used vehicles or cars with aftermarket wheels. The tire size printed on the current sidewall and the wheel measurement should agree. Even when two Sonata tire sizes have similar overall diameter, the bead seat must still match the correct rim diameter exactly.
Do all 2020 Hyundai Sonata sub-models use the same tire size?
No, 2020 Hyundai Sonata sub-models do not all use the same tire size. The lineup is split across 205/65R16, 215/55R17, and 235/45R18 fitments, with each size tied to specific trims. That means tire selection is trim-specific rather than one-size-fits-all across the entire Sonata range.
This matters most when replacing tires on a newly purchased Sonata or one that may have had wheel changes. Checking the trim badge alone may not be enough if the car has been modified, so it is smart to verify the tire size on the sidewall and confirm the wheel diameter as well. That prevents choosing a tire meant for a different Sonata setup.
Choosing the Right Tire
What should I consider when choosing a 2020 Hyundai Sonata tire?
Start with the correct Sonata tire size for the exact sub-model and wheel diameter, since this car uses 16-inch, 17-inch, and 18-inch fitments. After that, compare the tire’s construction, intended use, and any product details that matter for the setup, such as rim-width compatibility and load figures where those are stated.
A 17-inch or 18-inch Sonata owner may also want to compare tire series within the correct size instead of treating every option as the same. Daily driving priorities, wheel setup, and whether the car remains stock all influence the choice. The best approach is matching the tire to the trim, wheel, and how the car is actually used.
What sidewall styles are available for 2020 Hyundai Sonata tires?
The available 2020 Hyundai Sonata products shown here use a Blackwall sidewall style. That applies to the BFGoodrich options in both 215/55R17 and 235/45R18. For this Sonata fitment range, the visible sidewall choice is straightforward and stays within a modern blackwall presentation rather than a decorative vintage treatment.
Sidewall style still matters because it affects how the car looks once the correct size is chosen. A Sonata on 17-inch or 18-inch wheels can keep a clean, contemporary appearance with blackwall tires while the more important decisions shift to tire series and wheel compatibility. Style should follow size and fitment, not replace them.
What tire series are available for the 2020 Hyundai Sonata?
The available tire series for the 2020 Hyundai Sonata include BFGoodrich g-Force Comp 2 AS, g-Force Phenom T/A, and, in 235/45R18, g-Force Sport Comp 2. These series appear in the 17-inch and 18-inch Sonata fitments rather than across the full 16-inch through 18-inch range.
Series comparison is most useful after the correct size is confirmed. A 215/55R17 Sonata owner is comparing a different group of products than a 235/45R18 owner, so tire series should be evaluated within the proper trim-level fitment. That keeps the choice focused on the right package instead of crossing into sizes meant for other Sonata versions.
Restoration & Appearance
Does correct tire fitment matter for a 2020 Hyundai Sonata restoration?
Yes, correct tire fitment still matters on a 2020 Hyundai Sonata, even though it is a newer vehicle than a traditional collector car. The trim-specific tire size and wheel diameter are part of the car’s intended stance and overall presentation, so keeping the right 16-inch, 17-inch, or 18-inch setup helps preserve that character.
A restoration-minded approach on a modern Sonata usually means avoiding accidental mismatches between trim, wheel, and tire size. If appearance accuracy is important, compare the current setup to the exact sub-model before replacing anything. That is especially helpful on cars that may have received take-off wheels or aftermarket replacements at some point.
How does tire construction affect the appearance of a restored 2020 Hyundai Sonata?
Tire construction is less of a visual dividing line on a 2020 Hyundai Sonata because the primary fitments are all modern radial sizes. The more noticeable appearance factors are the correct tire dimensions for the trim and the blackwall presentation used by the available 17-inch and 18-inch products.
Keeping the proper size matters because sidewall height and section width help define how the Sonata sits on its wheels. A mismatched replacement can change that look even if it physically mounts to the wheel. For an appearance-conscious project, staying faithful to the original trim-level tire format is usually the cleaner path.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Hyundai Sonata?
Yes, modifications can affect tire fitment on a 2020 Hyundai Sonata. Aftermarket wheels, changes in wheel width, suspension lowering, or other alterations can move the car away from its original 205/65R16, 215/55R17, or 235/45R18 setup. That can change the fitment question from simple replacement to a full clearance and compatibility check.
A modified Sonata should be checked for actual wheel diameter, wheel width, and available space at the fender and suspension before choosing tires. Steering lock clearance is worth confirming as well. Even when the car still wears a familiar Sonata size, changes in the wheel or suspension package can alter what works safely.
What should I inspect before driving a 2020 Hyundai Sonata on new tires?
Before driving a 2020 Hyundai Sonata on new tires, inspect wheel condition, verify that all four tires match the intended size for the trim, and make sure the tires are properly seated and inflated. It is also smart to check for any rubbing points, especially if the car has different wheels than its original setup.
A short recheck after the first miles is worthwhile because it can reveal air loss, vibration, or clearance issues early. Look over the sidewalls for cuts or bulges, confirm lug hardware is secure, and make sure the car tracks normally. Catching small installation or fitment issues early helps prevent larger problems on the road.
How often should tires on a 2020 Hyundai Sonata be inspected?
Tires on a 2020 Hyundai Sonata should be inspected regularly, not just when replacement time arrives. Routine checks should include tread wear, air pressure, sidewall condition, and any signs of puncture damage or uneven wear. Those basics matter whether the car uses the 16-inch, 17-inch, or 18-inch Sonata tire package.
More frequent inspection makes sense when the Sonata is driven long distances, parked for extended periods, or fitted with aftermarket wheels. Uneven wear can point to alignment or suspension issues before they become expensive tire problems. Consistent pressure checks and visual inspections are the simplest way to protect both ride quality and tire life.
