2022 Genesis marked the Korean luxury brand’s push to stand toe-to-toe with established European sport sedans and executive cars, with the G70, G80, and G90 each aimed at a different kind of premium buyer. That broad range means tire fitment is not one-size-fits-all across the lineup. Eight radial sizes appear across three models, with some sizes shared between the larger G80 and G90 while others are unique to a single model or axle position. For most buyers, the first step is confirming the exact model and wheel diameter, then narrowing the choice to the correct front and rear size before comparing the available tire families.
Which Tire Size Is Right for Your 2022 Genesis
Eight tire sizes are used across 2022 Genesis vehicles, and they vary by model rather than being shared across the full range. The real choice starts with confirming whether your car uses 18-, 19-, or 20-inch wheels, then matching the exact metric radial size used on your G70, G80, or G90. Understanding that distinction before choosing a product saves time and helps ensure the right match.
Year(s): 2022|Fit(s): G70|Construction: Radial|Rim: 18 in
225/45R18 is a metric radial size with a 225 millimeter section width, a 45-series aspect ratio, and an 18-inch rim diameter. It is available from BFGoodrich and Nitto in blackwall form, with W speed-rated products reaching 112 mph. This size is specific to the G70 rather than universal across 2022 Genesis models, and it suits owners who need the factory-style 18-inch fitment for that model.
Year(s): 2022|Fit(s): G70|Construction: Radial|Rim: 19 in
225/40R19 is a metric radial size that uses a 225 millimeter section width, a 40-series aspect ratio, and a 19-inch rim. BFGoodrich offers this size in blackwall form, with W-rated products up to 112 mph. This size is specific to the G70 and is part of a lower-profile 19-inch setup, so it is the correct choice only for G70s equipped for that wheel diameter.
Year(s): 2022|Fit(s): G70|Construction: Radial|Rim: 19 in
255/35R19 is a metric radial size with a 255 millimeter section width, a 35-series aspect ratio, and a 19-inch rim diameter. BFGoodrich offers blackwall versions in both W and Y speed ratings, while the Y-rated option raises the speed ceiling to 186+ mph and the W-rated versions are rated to 112 mph. This size is specific to the G70 and typically serves the wider rear fitment on staggered 19-inch applications, so it matters most to owners matching the original front-to-rear setup.
Year(s): 2022|Fit(s): G80|Construction: Radial|Rim: 18 in
245/50R18 is a metric radial size with a 245 millimeter section width, a 50-series aspect ratio, and an 18-inch rim. Pro-Trac offers this size with RWL and redline sidewall styles. This size is specific to the G80, and it will appeal most to buyers who need the 18-inch fitment and want either a more understated black-tire look or a more distinctive sidewall accent.
Year(s): 2022|Fit(s): G80, G90|Construction: Radial|Rim: 19 in
245/45R19 is a metric radial size that combines a 245 millimeter section width, a 45-series aspect ratio, and a 19-inch rim diameter. It is available from BFGoodrich and Nitto in blackwall form, and speed ratings vary by product between W at 112 mph and Y at 186+ mph. This is one of the shared 19-inch Genesis sizes, so it is a key fitment for buyers comparing certain G80 and G90 applications.
Year(s): 2022|Fit(s): G80, G90|Construction: Radial|Rim: 19 in
275/40R19 is a metric radial size with a 275 millimeter section width, a 40-series aspect ratio, and a 19-inch rim. BFGoodrich and Nitto offer it in blackwall form, with W-rated products up to 112 mph and a Y-rated option reaching 186+ mph. This shared size fits only certain G80 and G90 applications, and it is the wider companion size buyers should confirm carefully on cars using a staggered 19-inch arrangement.
Year(s): 2022|Fit(s): G80|Construction: Radial|Rim: 20 in
245/40R20 is a metric radial size with a 245 millimeter section width, a 40-series aspect ratio, and a 20-inch rim diameter. BFGoodrich, Nitto, and Pro-Trac offer this size, with blackwall and RWL sidewall styles and speed ratings that vary by product between W at 112 mph and Y at 186+ mph. This size is specific to the G80 and belongs to the model’s larger-diameter wheel package, so buyers should confirm 20-inch wheels before choosing it.
Year(s): 2022|Fit(s): G80|Construction: Radial|Rim: 20 in
275/35R20 is a metric radial size using a 275 millimeter section width, a 35-series aspect ratio, and a 20-inch rim. BFGoodrich, Nitto, and Pro-Trac offer it in blackwall and RWL styles, with speed ratings that vary by product between W at 112 mph and Y at 186+ mph. This size is specific to the G80 and is the wider 20-inch companion size, so it is best suited to owners matching the original staggered wheel-and-tire package.
Three Genesis models are covered for 2022, and they do not all use the same tire sizes. The G70, G80, and G90 each have their own fitment pattern, with the G80 spanning the widest range and sharing some 19-inch sizes with the G90. Select your model below to narrow the fitment history and see the tire sizes that apply to your specific car.
2022 Genesis G70
The 2022 Genesis G70 is the sport sedan of the group, aimed at buyers who wanted a more athletic, compact luxury car. Its tires mount on 18-inch or 19-inch wheels depending on configuration, and the 19-inch setup uses two different sizes that should be matched carefully front to rear.
The 2022 Genesis G80 is the core midsize luxury sedan in the lineup, balancing comfort, style, and modern performance. Its tires mount on 18-inch, 19-inch, or 20-inch wheels depending on equipment, making it the model where wheel diameter matters most before selecting a tire.
The 2022 Genesis G90 is the flagship sedan, tuned more toward full-size luxury and long-distance comfort than outright sportiness. Its tires mount on 19-inch wheels, and it shares its two sizes with certain G80 applications rather than using a unique Genesis-only fitment.
Twenty-eight products are available across eight tire sizes for 2022 Genesis vehicles. 225/45R18, 245/45R19, 275/40R19, 245/40R20, and 275/35R20 come from BFGoodrich and Nitto in radial blackwall form; 225/40R19 and 255/35R19 are BFGoodrich radial blackwalls; 245/50R18 is a Pro-Trac radial in RWL or redline. Confirm your exact size first, since speed ratings vary within several sizes.
These answers cover how 2022 Genesis tire sizes change from G70 to G80 to G90, what the metric size codes mean, where 19-inch sizes overlap, and how speed ratings, sidewall styles, and collector-style care affect the right choice.
Size Basics & Fitment
What tire sizes fit 2022 Genesis vehicles?
2022 Genesis vehicles use eight tire sizes across three models: 225/45R18, 225/40R19, and 255/35R19 for the G70; 245/50R18, 245/45R19, 275/40R19, 245/40R20, and 275/35R20 for the G80; and 245/45R19 plus 275/40R19 for the G90. Rim diameters span 18, 19, and 20 inches. Rim width guidance appears on several products, including 7.0 to 8.5 inches for 225/45R18, 7.5 to 9 inches for 245/45R19, 9 to 11 inches for 275/40R19, 8 to 9.5 inches for 245/40R20, and 9 to 11 inches for 275/35R20.
That means year and make alone are not enough to choose a tire for a 2022 Genesis. You need to identify the model first, then confirm whether the car uses an 18-, 19-, or 20-inch wheel package, and on staggered applications you also need to separate front and rear sizes. Once that is settled, comparing brands and speed ratings becomes much easier.
What does 225/45R18 mean on a 2022 Genesis tire?
On a 2022 Genesis, 225/45R18 is a metric radial size. The 225 is the nominal section width in millimeters, 45 is the aspect ratio, the R indicates radial construction, and 18 is the wheel diameter in inches. This size belongs to the G70 and uses 18-inch wheels, with product rim-width guidance centered around 7.0 to 8.5 inches.
That decoding matters because a modern Genesis tire size is really a package of width, profile, construction, and wheel diameter rather than just a single number. If your G70 has 19-inch wheels, 225/45R18 is not an interchangeable substitute. The sidewall height and wheel diameter are both different, so the first check should always be the exact size on the tire placard or the tire already on the car.
Do all 2022 Genesis models use the same tire size?
No. The 2022 Genesis lineup uses different sizes by model, and only two sizes are shared across models: 245/45R19 and 275/40R19 appear on both the G80 and G90. The G70 has its own 18-inch and 19-inch combinations, while the G80 also reaches into 20-inch fitments that do not apply to the other Genesis sedans in this model year.
That makes model identification essential before replacing tires on a 2022 Genesis. It also matters whether your car uses a square setup or a staggered arrangement with a wider rear tire. If you are comparing the G80 and G90, the overlap in 19-inch sizes can simplify the search, but it is still wise to verify the exact front and rear sizes on the car before moving forward.
Buying the Right Tire
What sidewall styles are available for 2022 Genesis tires?
Most 2022 Genesis sizes are available as blackwall radials, which is the expected modern luxury-sedan presentation for the G70, G80, and G90. Two sizes also introduce alternate sidewall looks from Pro-Trac: 245/50R18 is available with RWL and redline styling, while 245/40R20 and 275/35R20 are available with RWL alongside blackwall choices from BFGoodrich and Nitto.
For a factory-style appearance, blackwall is the natural fit for a 2022 Genesis. RWL or redline options are more of a personalization choice than an authenticity requirement on a late-model luxury car. If appearance is a major part of your decision, choose the exact tire size first, then compare which sidewall treatments exist within that size rather than assuming every style is available in every fitment.
What brands make tires for 2022 Genesis vehicles?
2022 Genesis tire fitments are covered here by BFGoodrich, Nitto, and Pro-Trac. BFGoodrich appears across nearly the full range of 18-, 19-, and 20-inch sizes, Nitto supports several of the performance-oriented fitments in blackwall radial form, and Pro-Trac appears on 245/50R18, 245/40R20, and 275/35R20 with more style-driven sidewall options.
Brand choice on a 2022 Genesis often comes down to the exact size on the car and the look you want. Some sizes have a broad mix of BFGoodrich and Nitto performance radials, while others lean more heavily toward a single brand or style family. Once you know the size, compare speed rating, sidewall appearance, and rim-width compatibility instead of choosing by brand name alone.
What is the difference between BFGoodrich g-Force Phenom T/A and Nitto NT555 G2 for the 2022 Genesis?
On shared 2022 Genesis sizes such as 225/45R18, 245/45R19, 275/40R19, 245/40R20, and 275/35R20, BFGoodrich g-Force Phenom T/A and Nitto NT555 G2 are both radial blackwall choices, but their published specs are not always identical. The BFGoodrich Phenom T/A carries Y ratings in several sizes, including 255/35R19, 245/45R19, 275/40R19, 245/40R20, and 275/35R20, while the Nitto NT555 G2 in these Genesis fitments appears with W ratings. Weight also varies slightly by size, such as 29.26 pounds versus 29.65 pounds in 245/45R19.
For a 2022 Genesis owner, that comparison is less about one tire being universally better and more about matching the product to the car’s use and the exact size needed. If you want to compare close alternatives within the same fitment, start with speed rating and then look at rim-width guidance where it is published. Keeping the comparison size-specific prevents small spec differences from getting lost.
Fitting & Setup
What rim width do 2022 Genesis tires require?
Several 2022 Genesis sizes include clear rim-width guidance. 225/45R18 fits 7.0 to 8.5-inch rims, 225/40R19 fits 7.5 to 9-inch rims, 255/35R19 fits 8.5 to 10-inch rims, 245/45R19 fits 7.5 to 9-inch rims, 275/40R19 fits from 9 to 11 inches depending on product, 245/40R20 fits 8 to 9.5 inches, and 275/35R20 fits 9 to 11 inches. The 245/50R18 products do not publish a rim-width range here.
Those numbers are worth checking against the actual wheel on the car before choosing a replacement for a 2022 Genesis. They help confirm that the tire will sit on the wheel correctly and preserve the intended shape of the sidewall. On staggered setups, check front and rear wheels separately because the wider rear sizes need noticeably wider rims than the front.
Do 2022 Genesis tires require inner tubes?
The 2022 Genesis fitments here are all modern radial sizes, and none of the size markings indicate tube-type construction. They are tubeless-style fitments consistent with late-model passenger car wheels. You do not see TT markings in these Genesis products, and the product families are the kind normally used on modern tubeless rims.
That still does not mean every wheel-and-valve combination should be taken for granted. If a 2022 Genesis has aftermarket wheels, damaged beads, or valve stems of unknown age, those areas deserve inspection during tire replacement. On a modern luxury car, seal quality at the wheel and valve stem is usually more important than any question of tube fitment.
Can the original 2022 Genesis wheels be used with all tire sizes?
No, because 2022 Genesis vehicles use more than one wheel diameter across the lineup. The G70 uses 18-inch and 19-inch fitments, the G80 uses 18-, 19-, and 20-inch fitments, and the G90 uses 19-inch fitments. A tire must match the wheel diameter exactly, so an 18-inch tire cannot be mounted on a 19-inch wheel and a 19-inch tire cannot be mounted on a 20-inch wheel.
Original wheels can be reused when the replacement tire matches the wheel diameter and falls within an appropriate rim-width range for that size. That is especially important on Genesis models with staggered setups, where front and rear wheels are not the same width. Before ordering, confirm both the wheel diameter and whether the car uses paired front and rear sizes.
Maintenance, Storage & Longevity
How should I store a 2022 Genesis when the tires are fitted?
A 2022 Genesis should be stored on clean, properly inflated tires in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment. Even modern radials age faster when they sit in heat and UV exposure, and low-use luxury cars can develop pressure loss or mild temporary flat-spotting if they remain parked for long stretches.
Moving the car periodically, rolling it a short distance, or using stands during extended storage can help reduce stress on one contact patch. Keep the tires off damp soil or bare ground, and check pressure before and after storage instead of assuming it stayed stable. A little attention during storage goes a long way toward preserving ride quality when the car goes back on the road.
How long do tires on a 2022 Genesis typically last?
On a 2022 Genesis, tire age is usually a more important replacement factor than mileage once the car becomes a lower-use luxury vehicle. A good rule is to begin age-based evaluation around five to seven years and to treat around ten years as the outer edge for serious replacement consideration, regardless of tread depth. The DOT date code on the sidewall is the quickest way to confirm the tire’s manufacturing age.
That matters because a Genesis can accumulate relatively low mileage while still spending years exposed to heat cycles, parking, and environmental aging. A tire that looks acceptable at a glance can still be old enough to warrant closer inspection. If the date code shows the tires are well into that age window, inspect more critically for hardening, cracking, and irregular wear before trusting them for regular driving.
How often should tires on a 2022 Genesis be inspected?
Tires on a 2022 Genesis deserve a quick inspection before every drive and a more thorough inspection before longer highway trips. Look for cuts, bulges, punctures, visible sidewall cracking, uneven tread wear, and signs of pressure loss. Because several Genesis fitments are staggered, inspect front and rear tires as separate pairs rather than assuming they will wear or age the same way.
Regular checks are especially valuable on performance-oriented low-profile sizes because impacts and underinflation can show up quickly in ride quality and shoulder wear. A monthly pressure check is a good baseline even if the car is driven sparingly. Catching one damaged tire early can prevent unnecessary wear on the matching tire at the same axle position.
Safety & Road Use
Are 2022 Genesis tires safe for highway driving?
Yes, the 2022 Genesis fitments here are modern radial tires intended for highway use, and the published speed ratings support normal U.S. interstate driving with a wide margin. W-rated products are rated to 112 mph, and Y-rated products are rated to 186+ mph. Those numbers apply to the tire itself under proper conditions and do not override the vehicle’s own mechanical condition, alignment, load, or inflation needs.
For most G70, G80, and G90 owners, the larger concern is not whether the tire can handle highway speeds, but whether the entire car is in equally good condition for sustained travel. Pressure, tread condition, suspension wear, and brake health all matter. Matching the correct front and rear sizes also plays a major role in preserving the stable road manners Genesis intended.
What inflation pressure should I use for 2022 Genesis tires?
Inflation pressure for a 2022 Genesis should follow the car’s tire placard or owner’s manual first, because the vehicle manufacturer sets the operating pressure around weight distribution, ride, and handling. Some tire products also publish maximum load and pressure figures, including 1521 pounds at 50 psi for certain 225/45R18 products, 1874 pounds at 50 psi for one 245/45R19, 2039 pounds at 50 psi for one 275/40R19, 1709 pounds at 50 psi for one 245/40R20, and 1874 pounds at 50 psi for one 275/35R20.
Those tire maximums are not blanket running-pressure recommendations for every 2022 Genesis application. They are upper-rated values tied to load capacity for that specific tire. Use the Genesis placard to establish day-to-day pressure, then confirm that the chosen tire’s published limits are appropriate for the application. Never transfer one size’s pressure figure to another size just because the numbers look close.
What should I check before taking a 2022 Genesis on a longer drive?
Before a longer drive in a 2022 Genesis, inspect each tire for cracking, punctures, exposed cords, bulges, uneven wear, and proper cold inflation pressure. Check that the front and rear tires match the correct sizes for the car, especially on staggered G70 and G80 applications. It is also wise to inspect the spare if the car carries one, along with valve stems and the condition of each wheel.
A sound tire check should be part of a broader pre-trip lookover on any luxury sedan, even one as new as a 2022 Genesis. Brakes, alignment feel, fluid levels, and suspension condition all influence how confidently the car will travel at speed. Starting with the tires makes sense because they are the one part of the car that must manage load, steering, braking, and road contact at the same time.
