The 2020 Hyundai Elantra GT sits in the modern hatchback sweet spot, blending everyday practicality with a more European-flavored compact-car feel than many mainstream sedans. Its five-door layout and sharper road manners make tire choice especially important, because the right size helps preserve both appearance and the balanced character that draws buyers to this model. Tire fitment depends on sub-model: the Elantra GT Base uses 225/45R17, while the N Line steps up to 225/40R18, and both are radial fitments. Available choices include performance-oriented series from BFGoodrich, Nitto, and Pro-Trac, with blackwall, redline, and raised white letter styling in 17-inch form. The key is matching the exact sub-model and wheel diameter before comparing tire series and sidewall presentation.
Which Tire Size Is Right for The 2020 Hyundai Elantra GT
The 2020 Hyundai Elantra GT uses two primary tire sizes, and the correct one depends on the exact sub-model. Both fitments are radial, but they use different wheel diameters, so the first step is confirming whether the car is a Base model on 17-inch wheels or an N Line on 18-inch wheels before comparing tire series, sidewall style, and other product differences.
A 225/40R18 tire keeps the same 225-millimeter nominal width but uses a lower 40-series profile on an 18-inch rim. For the 2020 Hyundai Elantra GT, this radial size applies to the N Line and points the buyer toward confirming the larger wheel diameter before comparing available tires. Choices in this size include BFGoodrich and Nitto performance-oriented series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2, all in blackwall form. This fitment makes the most sense when the car retains its 18-inch setup and the buyer wants to stay within the proper N Line size range.
Sub-model fitment matters on the 2020 Hyundai Elantra GT because tire size changes with trim. The Base and N Line do not share the same wheel diameter, so identifying the exact sub-model is the first step before comparing available tire options.

2020 Hyundai Elantra GT Base
The 2020 Hyundai Elantra GT Base uses a 225/45R17 radial tire on a 17-inch wheel. That makes tire selection more about choosing among available brands, series, and sidewall styles in the correct size than deciding between different primary fitments.
The 2020 Hyundai Elantra GT N Line uses a 225/40R18 radial tire on an 18-inch wheel. Tire selection starts with confirming the 18-inch setup, then comparing the available blackwall performance-oriented options within that exact 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.

Common 2020 Hyundai Elantra GT tire questions usually come down to identifying the correct size by sub-model, confirming 17-inch versus 18-inch wheel fitment, and comparing available radial tire series, sidewall styles, and maintenance considerations before road use.
Tire Size & Fitment
What tire size fits a 2020 Hyundai Elantra GT?
The 2020 Hyundai Elantra GT uses two tire sizes depending on sub-model. The Base model uses 225/45R17, while the N Line uses 225/40R18. Both are radial fitments, but they are tied to different wheel diameters, so the correct size starts with the exact trim and wheel setup on the car.
The practical difference is that this is not a case of choosing between two interchangeable sizes. A buyer should confirm whether the car is a Base or N Line, then verify that the wheels on the vehicle are still 17-inch or 18-inch as expected, especially if it has changed hands or has been modified.
What size rim does a 2020 Hyundai Elantra GT use?
A 2020 Hyundai Elantra GT uses either a 17-inch or 18-inch rim, depending on sub-model. The Base model is paired with 225/45R17 tires on 17-inch wheels, and the N Line uses 225/40R18 tires on 18-inch wheels. Rim diameter is part of the tire size itself, so it must match exactly.
That wheel-diameter difference is the first fitment check to make before comparing any tire options. Even though both sizes share a 225-millimeter width, a 17-inch tire cannot be mounted on an 18-inch wheel, and an 18-inch tire cannot be mounted on a 17-inch wheel.
Do all 2020 Hyundai Elantra GT sub-models use the same tire size?
No, the 2020 Hyundai Elantra GT sub-models do not use the same tire size. The Base uses 225/45R17, while the N Line uses 225/40R18. Both are radial tires, but the sizes reflect different wheel diameters and slightly different overall tire profiles between the two versions.
That means tire selection begins with trim identification rather than brand or tread preference. Once the sub-model is confirmed, the buyer can narrow the search to the correct size and compare available series, sidewall treatments, and wheel-width compatibility without risking a mismatch at the rim.
Choosing the Right Tire
What should I consider when choosing a 225/45R17 tire for a 2020 Hyundai Elantra GT?
A 225/45R17 tire for the 2020 Hyundai Elantra GT Base should first match the correct 17-inch wheel diameter and radial construction. After that, the main comparison points are tire series, brand, sidewall style, and wheel-width compatibility, since this size is available from BFGoodrich, Nitto, and Pro-Trac in several distinct product lines.
Selection comes down to how the car is used and how the owner wants it to look. Blackwall options keep a modern appearance, while raised white letter and redline versions add a more expressive presentation. Checking the actual wheel width on the car helps narrow the field before making a final choice.
What sidewall styles are available for 2020 Hyundai Elantra GT tires?
Sidewall style depends on size. In 225/45R17 for the 2020 Hyundai Elantra GT Base, available choices include blackwall, raised white letter, and redline. In 225/40R18 for the N Line, the available products are blackwall. That makes sidewall presentation a bigger decision on the 17-inch fitment than on the 18-inch fitment.
A buyer choosing 17-inch tires can balance visual character with the rest of the car’s look, especially if the goal is something sportier or more distinctive than a plain black sidewall. The N Line’s 18-inch choices stay more contemporary in appearance, so the decision there is more about tire series and brand than sidewall styling.
What brands offer tires for the 2020 Hyundai Elantra GT?
Tires for the 2020 Hyundai Elantra GT are available from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich and Nitto appear in both 225/45R17 and 225/40R18, while Pro-Trac appears in 225/45R17. The available series include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, NT555 G2, and Street Pro III.
Brand choice should follow fitment first, then the type of presentation and product character the buyer wants. A Base model owner has the broadest visual range because 17-inch options include blackwall, raised white letter, and redline treatments, while N Line buyers are comparing blackwall performance-oriented offerings in the correct 18-inch size.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Hyundai Elantra GT?
A period-style approach on a 2020 Hyundai Elantra GT still starts with the correct sub-model size: 225/45R17 for the Base or 225/40R18 for the N Line. Because this is a modern hatchback rather than a vintage restoration platform, the more appearance-driven choices appear mostly in 225/45R17, where raised white letter and redline sidewalls are available.
That gives Base model owners more room to shape the car’s visual character without stepping outside the proper size. N Line owners have a narrower styling path in blackwall form, so the emphasis shifts toward keeping the correct low-profile 18-inch fitment and choosing a tire series that suits the car’s intended road use.
How does tire construction affect the appearance of a restored 2020 Hyundai Elantra GT?
On the 2020 Hyundai Elantra GT, construction is straightforward because the primary fitments are radial in both sizes. The appearance differences come less from bias-ply versus radial choice and more from the sidewall treatment, wheel diameter, and profile shape, especially when comparing the 17-inch Base setup to the lower-profile 18-inch N Line fitment.
For a clean, stock-like presentation, staying with the correct radial size and proper wheel diameter matters more than pursuing an older tire look. Buyers aiming for a more customized visual theme can explore blackwall, raised white letter, or redline styling where available, but the tire still needs to match the car’s exact trim and wheel setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Hyundai Elantra GT?
Yes, modifications can affect tire fitment on a 2020 Hyundai Elantra GT. Aftermarket wheels, suspension changes, lowering, or body alterations can change the clearance available for either the 225/45R17 Base fitment or the 225/40R18 N Line fitment. Even when the tire size remains the same, wheel width and offset can still alter how the tire sits.
That is why the actual setup on the car should be checked before choosing tires, especially on a used or modified example. Verifying wheel diameter, wheel width, and visible clearance at the fender and suspension helps prevent fitment surprises and keeps the selection process focused on the right size for the car as it sits today.
What should I inspect before driving a 2020 Hyundai Elantra GT on new tires?
Before driving a 2020 Hyundai Elantra GT on new tires, confirm that the tire size matches the correct sub-model and wheel diameter, then inspect the wheels for damage or irregular wear issues. Tire pressure should be set properly, and the tires should be checked for any mounting or balance concerns before the car goes back into regular service.
A quick road-use inspection should also include tread seating, valve condition, and basic clearance at full steering lock where practical. Any vibration, pulling, or rubbing after installation deserves attention right away, since those symptoms can point to alignment issues, wheel damage, or a mismatch between the tire and the car’s current setup.
How often should tires on a 2020 Hyundai Elantra GT be inspected?
Tires on a 2020 Hyundai Elantra GT should be inspected regularly, not just when tread looks low. Frequent checks for uneven wear, cuts, bulges, sidewall damage, and air loss are especially useful on a car that sees mixed city and highway driving, because those patterns can reveal alignment, inflation, or suspension issues early.
A good routine is to look them over during normal cleaning or fueling and give them a closer inspection before longer trips. Cars that are driven less often still benefit from regular checks, since age, underinflation, and prolonged parking can affect condition even when mileage accumulates slowly.
