The 2018 Chevrolet Cruze sits in the later chapter of the compact Chevrolet sedan and hatchback story, aimed at drivers who wanted efficient daily use without giving up a more tailored trim or appearance package. On this model, tire fitment is closely tied to trim level, with four primary radial sizes used across the Cruze lineup: 195/65R15, 205/55R16, 225/45R17, and 225/40R18. That makes the real decision less about vintage-style construction and more about confirming the exact sub-model and wheel diameter first. From straightforward blackwall performance radials to a wide whitewall or redline presentation in certain sizes, the right choice depends on how the car is equipped and how you want it to look and drive.
Which Tire Size Is Right for The 2018 Chevrolet Cruze
The 2018 Chevrolet Cruze uses four primary tire sizes, and they are split by sub-model and wheel diameter rather than by bias-ply versus radial construction. Every fitment here is radial, so the first step is identifying the exact trim and confirming whether the car is on 15-, 16-, 17-, or 18-inch wheels before comparing brands, sidewall styles, or tire series.
205/55R16 is a modern metric radial size in which 205 is the section width in millimeters, 55 is the aspect ratio, and 16 is the rim diameter in inches. On the 2018 Chevrolet Cruze, this size supports a balanced trim-level fitment with a radial construction suited to everyday road use. Available choices include BFGoodrich, Michelin, and American Classic, with blackwall and wide whitewall sidewall treatments depending on the look you want. It is a useful size to evaluate when your Cruze uses 16-inch wheels and you want either a conventional modern appearance or something more distinctive.
195/65R15 is a metric radial size where 195 indicates section width in millimeters, 65 is the aspect ratio, and 15 identifies the wheel diameter. This size is used on certain 2018 Chevrolet Cruze trims that carry the smallest wheel fitment in the lineup, making wheel confirmation especially important before replacement. The format reflects a practical modern radial package rather than a specialty or appearance-driven fitment. It is the right size to focus on when the car remains on its original 15-inch wheel setup and the goal is to maintain the correct base fitment.
225/40R18 is a metric radial size with a 225-millimeter section width, a 40-series profile, and an 18-inch rim diameter. On the 2018 Chevrolet Cruze, it belongs to trims equipped with the largest wheel option, so it carries a more appearance- and package-specific role than the smaller Cruze tire sizes. Product choices include BFGoodrich and Nitto in blackwall performance-oriented series such as g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and NT555 G2. It deserves a careful look when the car has 18-inch wheels and you want to stay with the low-profile factory-style sizing approach.
225/45R17 is a metric radial size where 225 gives the nominal section width in millimeters, 45 is the aspect ratio, and 17 is the wheel diameter in inches. For the 2018 Chevrolet Cruze, this size appears on higher trim and package-related fitments and offers the broadest visible product variety among the listed sizes. Blackwall, raised white letter, and redline sidewall treatments are available, along with BFGoodrich, Nitto, and Pro-Trac tire series. It is the size to compare closely when your Cruze runs 17-inch wheels and appearance matters alongside basic fitment.
Tire fitment on the 2018 Chevrolet Cruze varies by sub-model, and some trims use more than one wheel-and-tire package. Checking the exact trim is the key step before selecting a replacement, especially because the Cruze spans four different rim diameters.

2018 Chevrolet Cruze Diesel
The 2018 Chevrolet Cruze Diesel uses a single radial tire fitment built around the 16-inch wheel package. That keeps selection relatively straightforward, with the main decision centered on brand, sidewall style, and whether the car still carries its original wheel setup.
The 2018 Chevrolet Cruze L uses the 15-inch radial fitment, giving it the smallest wheel diameter in the Cruze range. Tire selection starts with staying in the correct size and confirming that the car has not been changed to a different wheel package over time.
The 2018 Chevrolet Cruze LS shares the same 15-inch radial tire fitment as the L. That makes replacement fairly direct as long as the existing wheels are still the correct diameter and the car has not been upgraded to another trim's wheel package.
The 2018 Chevrolet Cruze LT uses the 16-inch radial fitment rather than the smaller base wheel package. That gives the owner room to compare available blackwall and wide whitewall options while still keeping the focus on correct 16-inch wheel compatibility.
The 2018 Chevrolet Cruze LT w/RS Pkg. uses either a 17-inch or 18-inch radial fitment, so wheel diameter must be confirmed before anything else. Once that is settled, the decision becomes a comparison of low-profile tire choices, sidewall presentation, and tire series character.
The 2018 Chevrolet Cruze Premier also uses either the 17-inch or 18-inch radial fitment depending on wheel setup. That means tire replacement should begin with an exact check of the installed wheel diameter rather than assuming every Premier uses the same 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.
Best 2018 Chevrolet Cruze Tires for Sale
Available 2018 Chevrolet Cruze tire choices vary by size, with BFGoodrich, Michelin, Nitto, Pro-Trac, and American Classic options across several radial series. Depending on the wheel package, buyers can compare blackwall, wide whitewall, raised white letter, and redline sidewall treatments.
These FAQs focus on 2018 Chevrolet Cruze tire size by trim, wheel-diameter differences, product and sidewall choices, and the fitment checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2018 Chevrolet Cruze?
A 2018 Chevrolet Cruze can use 195/65R15, 205/55R16, 225/45R17, or 225/40R18 depending on the sub-model and wheel package. The L and LS use 195/65R15, the Diesel and LT use 205/55R16, and the LT w/RS Pkg. and Premier use either 225/45R17 or 225/40R18.
That means there is no single universal Cruze tire size for 2018. Start by confirming the exact trim and then check the installed wheel diameter on the car, because the upper trims can use more than one fitment and the difference between 17-inch and 18-inch wheels changes the correct tire size completely.
What size rim does a 2018 Chevrolet Cruze use?
The 2018 Chevrolet Cruze uses four possible rim diameters: 15, 16, 17, and 18 inches. Those diameters correspond to the four primary tire sizes used on the car, so rim size is tied directly to the trim level and wheel package rather than being a one-size-fits-all specification.
Wheel diameter is the first thing to verify before ordering replacement tires, especially on LT w/RS Pkg. and Premier models that can carry either 17-inch or 18-inch fitments. A quick inspection of the current tire sidewall or the wheel itself helps prevent choosing the right tire size for the wrong wheel diameter.
Why does the 2018 Chevrolet Cruze have more than one tire size?
The 2018 Chevrolet Cruze has more than one tire size because Chevrolet used different wheel-and-tire packages across the model range. Base-oriented trims use smaller wheel diameters, while upper trims and appearance-package versions move into 16-, 17-, or 18-inch fitments with lower-profile radial sizes.
That variation matters because two Cruzes from the same model year can need completely different tires. Tire replacement should follow the actual trim and wheel setup on the car, not just the year and model name, and any past wheel upgrade or package change should be confirmed before comparing available tire options.
Choosing the Right Tire
What should I consider when choosing a 2018 Chevrolet Cruze tire?
Start with the correct tire size for the exact sub-model and wheel diameter, because the 2018 Chevrolet Cruze spans four different radial fitments. After that, compare construction details that matter in the available products, such as rim-width compatibility, sidewall style, tire series, and load figures where they are given.
The best way to narrow the field is to decide whether the car is a basic daily driver, an appearance-focused trim, or something modified from stock. A 15-inch L or LS calls for a different buying approach than a 17-inch or 18-inch RS-package car, and sidewall style may matter just as much as brand on certain setups.
What sidewall styles are available for 2018 Chevrolet Cruze tires?
Sidewall styles for the 2018 Chevrolet Cruze include blackwall, wide whitewall, raised white letter, and redline, depending on the tire size. Blackwall is the most common look across the 16-, 17-, and 18-inch fitments, while wide whitewall appears in 205/55R16 and raised white letter and redline appear in 225/45R17.
That gives Cruze owners some room to shape the car's presentation instead of treating every replacement as visually identical. Sidewall style still needs to be chosen within the correct tire size, so appearance should come after wheel-diameter and fitment confirmation, especially on trims that could have left the factory with either 17-inch or 18-inch wheels.
What brands offer tires for the 2018 Chevrolet Cruze?
Available 2018 Chevrolet Cruze tire brands include BFGoodrich, Michelin, American Classic, Nitto, and Pro-Trac, depending on the size. BFGoodrich appears across several Cruze fitments, while Michelin and American Classic are present in 205/55R16, Nitto appears in 17- and 18-inch sizes, and Pro-Trac appears in 225/45R17.
Brand choice should be matched to the actual wheel package and the kind of presentation you want from the car. Some Cruze sizes lean toward blackwall performance-style options, while others open the door to whitewall, raised white letter, or redline looks, so it helps to compare the size-specific product mix rather than shopping by brand alone.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Chevrolet Cruze?
A period-style 2018 Chevrolet Cruze tire choice still begins with the correct modern radial size for the car's trim and wheel diameter. Among the available products, 205/55R16 offers a wide whitewall option, while 225/45R17 offers raised white letter and redline presentations that can give the Cruze a more customized appearance.
Appearance-driven selection works best after the fitment basics are settled. Confirm the exact wheel diameter on the car, then decide whether the goal is a subtle modern look with blackwalls or a more noticeable visual statement, keeping in mind that sidewall style changes the character of the car without changing the need for correct sizing.
How does tire construction affect the appearance of a restored 2018 Chevrolet Cruze?
On the 2018 Chevrolet Cruze, construction does not create a bias-ply versus radial appearance choice because the primary fitments are all radial. The visible difference comes instead from tire size, profile, and sidewall treatment, with blackwall, wide whitewall, raised white letter, and redline options shaping how the car presents itself.
That means an appearance-focused Cruze build is more about matching the tire's visual style to the trim and wheel package than choosing between old and new construction types. Lower-profile 17-inch and 18-inch tires naturally create a different stance than the 15-inch and 16-inch fitments, so wheel setup and sidewall style should be considered together.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Chevrolet Cruze?
Yes. Modifications can affect tire fitment on a 2018 Chevrolet Cruze, especially if the car has aftermarket wheels, suspension changes, or a wheel package borrowed from another trim. The Cruze already uses four different factory tire sizes, so even modest changes in wheel diameter or width can alter what size works safely on the car.
A modified Cruze should be checked for actual wheel diameter, wheel width, and clearance at the fender and steering components before replacing tires. Lowered suspension, offset changes, and plus-size wheel conversions can all influence the right choice, even when the tire size looks close to a stock Cruze specification on paper.
What should I inspect before driving a 2018 Chevrolet Cruze on new tires?
Before driving a 2018 Chevrolet Cruze on new tires, inspect the wheel diameter and make sure the installed tire size matches the trim's intended fitment. It also helps to check air pressure, look for any wheel damage, and confirm that the tires clear the fenders, suspension, and steering components through their normal range of movement.
A short follow-up inspection after the first miles is worthwhile, particularly if the car uses a 17-inch or 18-inch low-profile setup. Recheck pressure, look for uneven contact or rubbing, and make sure any recent alignment, wheel, or suspension work has not created a fitment issue that was hidden before the new tires were installed.
How often should tires on a 2018 Chevrolet Cruze be inspected?
Tires on a 2018 Chevrolet Cruze should be inspected regularly for air loss, tread wear, cuts, bulges, and sidewall cracking, rather than waiting for a problem to become obvious on the road. A routine visual check is especially important if the car is driven infrequently or if it uses lower-profile 17-inch or 18-inch tires.
Consistent inspection matters because the Cruze can wear very different tire packages depending on trim, and each setup benefits from proper pressure and even wear. Cars stored outdoors, parked for long stretches, or running modified wheels deserve closer attention, since age, underinflation, and clearance issues can all shorten tire life before tread is fully used.
