The 2019 Hyundai Elantra GT brought hatchback practicality into a compact package with a more European-leaning profile than many mainstream small cars. For buyers who use one as a daily driver, sport compact, or lightly modified street car, tire selection has a real effect on both appearance and road feel. This model uses radial tires, with 225/45R17 on the Base and 225/40R18 on the N Line. Available choices include blackwall performance radials, plus raised white letter and redline options in the 17-inch size. The key is matching the exact sub-model and wheel diameter first, then choosing the tire style and series that suits how the car is actually driven.
Which Tire Size Is Right for The 2019 Hyundai Elantra GT
The 2019 Hyundai Elantra GT uses two primary tire sizes, and the correct one depends on the sub-model and wheel diameter. The Base uses a 17-inch radial setup, while the N Line uses an 18-inch radial setup, so the first step is confirming which version of the car you have and verifying the actual wheels on the car before choosing among the available tire styles and series.
In 225/45R17, the 225 is the tire's nominal section width in millimeters, 45 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2019 Hyundai Elantra GT, this is the 17-inch radial fitment used on the Base model. Available choices include BFGoodrich, Nitto, and Pro-Trac options, with blackwall, raised white letter, and redline sidewall treatments across several performance-oriented series. This size is the right place to start when the car retains its 17-inch wheel setup and the goal is choosing the right look and road character within that fitment.
In 225/40R18, the 225 indicates nominal section width in millimeters, 40 is the aspect ratio, R denotes radial construction, and 18 is the wheel diameter in inches. For the 2019 Hyundai Elantra GT, this is the 18-inch radial size used on the N Line. Product choices center on blackwall performance radials from BFGoodrich and Nitto, with series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. This size matters when keeping the N Line's wheel diameter and selecting among tires that differ more by series and specification than by sidewall styling.
Sub-model fitment matters on the 2019 Hyundai Elantra GT because the covered versions do not share the same tire size. Identifying whether the car is a Base or an N Line is the first step, since the wheel diameter changes along with the tire size.

2019 Hyundai Elantra GT Base
The 2019 Hyundai Elantra GT Base uses the 225/45R17 radial size on a 17-inch wheel. That keeps the buying decision focused on tire series, sidewall presentation, and wheel-width compatibility rather than sorting through multiple primary fitments.
The 2019 Hyundai Elantra GT N Line uses the 225/40R18 radial size on an 18-inch wheel. Tire selection here is mainly about choosing among the available performance-oriented blackwall radials while confirming the car still has its intended 18-inch wheel setup.
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.

Tire questions for the 2019 Hyundai Elantra GT usually come down to matching the correct sub-model, confirming 17-inch versus 18-inch wheels, and choosing the right radial tire series, sidewall style, and fitment setup for the way the car is used.
Tire Size & Fitment
What tire size fits a 2019 Hyundai Elantra GT?
The 2019 Hyundai Elantra GT uses two primary tire sizes. The Base model uses 225/45R17, while the N Line uses 225/40R18, and both are radial tire fitments tied to different wheel diameters.
That means the first job is identifying the exact sub-model and confirming the wheels currently on the car. If the Elantra GT has been changed from its original wheel setup, the sub-model alone may not be enough, so checking the tire sidewall and wheel diameter before replacement helps avoid ordering the wrong size.
What size rim does a 2019 Hyundai Elantra GT use?
A 2019 Hyundai Elantra GT uses either a 17-inch or 18-inch rim, depending on the sub-model. The Base is paired with a 17-inch wheel for 225/45R17 tires, and the N Line is paired with an 18-inch wheel for 225/40R18 tires.
Rim diameter is the non-negotiable part of the fitment, so a 17-inch tire cannot be mounted on an 18-inch wheel and vice versa. Checking wheel diameter first, then comparing wheel width and current tire size, is the cleanest way to narrow the correct replacement options for the car.
Why does the 2019 Hyundai Elantra GT have more than one tire size?
The 2019 Hyundai Elantra GT has more than one tire size because the covered sub-models use different wheel packages. The Base uses 225/45R17, while the N Line uses 225/40R18, so the tire size changes with the wheel diameter.
That difference affects replacement choices right away, since product selection, sidewall styles, and rim-width ranges vary by size. Anyone replacing tires should verify the exact sub-model and inspect the actual wheel and tire combination on the car, especially if it has aftermarket wheels or a previous owner changed the setup.
Choosing the Right Tire
What should I consider when choosing a 225/45R17 tire for a 2019 Hyundai Elantra GT?
For a 2019 Hyundai Elantra GT using 225/45R17, the main considerations are staying with the correct size, confirming the wheel matches the tire's rim-width requirements, and choosing the tire series and sidewall style that suit the car's use. This size has the broadest appearance range.
Blackwall options keep a modern performance look, while raised white letter and redline versions change the presentation noticeably. Comparing brands such as BFGoodrich, Nitto, and Pro-Trac also helps separate touring-leaning versus sport-leaning choices, but the first filter should still be correct fitment on the existing 17-inch wheel.
What sidewall styles are available for 2019 Hyundai Elantra GT tires?
Sidewall style depends on tire size. In 225/45R17 for the 2019 Hyundai Elantra GT Base, available choices include blackwall, raised white letter, and redline, while 225/40R18 options for the N Line are centered on blackwall radials.
That makes the 17-inch fitment more flexible for buyers who want a stronger visual statement, while the 18-inch fitment stays closer to a contemporary sport compact look. Sidewall style should be chosen after confirming the correct size, since appearance options are shaped by the wheel diameter and sub-model-specific tire fitment.
What brands offer tires for the 2019 Hyundai Elantra GT?
Tires for the 2019 Hyundai Elantra GT are available from BFGoodrich, Nitto, and Pro-Trac, depending on size. BFGoodrich appears across both 17-inch and 18-inch fitments, Nitto is also available in both sizes, and Pro-Trac appears in the 225/45R17 size.
Brand alone should not make the decision. It is more useful to compare the exact tire series, the sidewall treatment offered in the correct size, and the wheel-width specification for the car's current setup. That approach keeps the selection focused on actual fitment and the look or driving character you want.
Restoration & Appearance
Which tire should I choose for a period-style 2019 Hyundai Elantra GT?
A period-style approach on a 2019 Hyundai Elantra GT still starts with the correct modern radial size for the exact sub-model. For the Base, 225/45R17 gives the most flexibility because it includes blackwall, raised white letter, and redline options, while the N Line's 225/40R18 selection stays more contemporary.
Appearance goals should be balanced against the car's wheel diameter and intended use. A subtle blackwall keeps a cleaner late-model hatchback look, while redline or raised white letter creates a more customized presentation. Matching the tire style to the car matters, but keeping the correct size and wheel fitment matters more.
How does tire construction affect the appearance of a restored 2019 Hyundai Elantra GT?
On a 2019 Hyundai Elantra GT, construction does not create a bias-ply versus radial decision because the primary fitments are radial. Appearance is influenced more by sidewall treatment, tire series, and wheel diameter than by switching between basic construction types.
That means the visual choice is mostly between a straightforward blackwall performance look and, in the 225/45R17 size, more expressive raised white letter or redline styling. Anyone trying to preserve a cleaner original-type presentation should keep the sub-model's correct size first, then choose the sidewall style that best matches the car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Hyundai Elantra GT?
Yes, modifications can affect tire fitment on a 2019 Hyundai Elantra GT. Aftermarket wheels, suspension changes, lowering, or altered alignment settings can change the clearance available for 225/45R17 or 225/40R18 tires, even when the nominal size remains the same.
A car that no longer has its original wheel setup should be checked for wheel diameter, wheel width, and nearby clearance at the strut, fender, and steering range before replacing tires. That is especially important when choosing a performance-oriented tire, since actual section shape can vary by wheel and installation.
What should I inspect before driving a 2019 Hyundai Elantra GT on new tires?
Before driving a 2019 Hyundai Elantra GT on new tires, confirm that all four tires are the correct size for the car's wheel setup, check inflation pressure, and inspect for proper bead seating and valve condition. Lug torque and overall wheel condition also deserve attention.
A short recheck after the first miles is a smart habit, especially on a car used for spirited street driving. Watching for vibration, unusual rubbing, or uneven clearance during full steering lock can catch setup issues early, and it is also worth checking alignment if the old tires showed irregular wear.
How often should tires on a 2019 Hyundai Elantra GT be inspected?
Tires on a 2019 Hyundai Elantra GT should be inspected regularly rather than waiting for a service interval alone. Pressure, tread wear, cuts, punctures, sidewall damage, and uneven shoulder wear are the basics, especially on lower-profile performance sizes like 225/40R18.
Monthly checks are a sensible routine, with extra attention before longer trips or after hitting potholes and road debris. Looking over the inner sidewall and listening for changes in ride or noise can also help catch problems early, particularly on cars with firmer suspensions or aftermarket wheel and tire combinations.
