The 2018 Chevrolet Malibu sits in the modern midsize-sedan class, balancing everyday comfort with a cleaner, more streamlined look than many earlier family cars. Buyers often know it as a practical commuter, but tire choice still changes how the car presents itself and how closely replacement fitment matches the original setup. This Malibu uses radial tires, with fitment depending on sub-model and wheel package across 16-, 17-, 18-, and 19-inch rims. Available choices range from conventional blackwall performance-oriented radials to Silvertown Radial options with wide whitewall or redline styling in 225/55R17. The key is matching the exact sub-model and wheel diameter before narrowing the decision by appearance, tire series, and intended road use.
Which Tire Size Is Right for The 2018 Chevrolet Malibu
The 2018 Chevrolet Malibu uses four primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. All of them are radial sizes, but they are spread across 16-, 17-, 18-, and 19-inch rims, so the first step is confirming which wheels are actually on the car. Once that is settled, the decision shifts to tire series, sidewall style, and whether the goal is standard late-model appearance or something with a more distinctive visual treatment.
225/55R17 is a metric radial size in which 225 is the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 17 is the rim diameter in inches. On the 2018 Chevrolet Malibu, this size suits 17-inch wheel applications and keeps the fitment in a modern radial format. Available choices include BFGoodrich tires in g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, and Silvertown Radial lines, with blackwall, wide whitewall, and redline sidewall styles. This size is worth close attention for buyers who want the correct 17-inch fitment but also want room to shape the car's appearance.
205/65R16 is a metric radial size that uses a 205-millimeter nominal section width, a 65-series profile, and a 16-inch rim diameter. For the 2018 Chevrolet Malibu, it represents the 16-inch wheel fitment used on certain sub-models and keeps the car in a straightforward modern radial setup. This size has a taller-profile look than the larger wheel packages fitted elsewhere in the Malibu range, so it serves a different role even though overall tire diameter stays close to the other factory fitments. It is the size to verify when the car has 16-inch wheels and a more standard trim-level configuration.
245/40R19 is a metric radial size with a 245-millimeter nominal section width, a 40-series profile, and a 19-inch rim diameter. On the 2018 Chevrolet Malibu, this size belongs to the larger-wheel fitment used on specific upper trims or wheel packages, so it should not be confused with the 18-inch alternative that can appear on related sub-models. Available products are blackwall radials from BFGoodrich in the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series. This size deserves careful wheel confirmation first, since the 19-inch rim requirement is the defining fitment point.
245/45R18 is a metric radial size where 245 gives the nominal section width in millimeters, 45 is the aspect ratio, R marks radial construction, and 18 identifies the rim diameter in inches. For the 2018 Chevrolet Malibu, this size covers 18-inch wheel applications and appears on trims that can overlap with other larger-wheel fitments. Product choices include blackwall tires from BFGoodrich and Nitto, with several performance-oriented series available for comparison. This is the size to evaluate when the car has 18-inch wheels and the buyer wants to compare brand, series, and rim-width compatibility within that exact fitment.
Sub-model fitment matters on the 2018 Chevrolet Malibu because tire size changes across the range, and some trims use more than one wheel package. Identifying the exact trim and confirming the wheel diameter on the car will narrow the correct tire size before comparing brands, series, or appearance details.

2018 Chevrolet Malibu Hybrid
The 2018 Chevrolet Malibu Hybrid uses the 225/55R17 radial size, so the main fitment question centers on the 17-inch wheel setup rather than multiple primary sizes. Tire selection then becomes a matter of choosing between conventional blackwall offerings and more appearance-focused options such as wide whitewall or redline styling.
The 2018 Chevrolet Malibu L uses the 205/65R16 radial size, tied to a 16-inch wheel. That makes tire selection fairly straightforward, with the main priority being confirmation that the car still retains the correct wheel diameter and has not been changed to a different Malibu wheel package.
The 2018 Chevrolet Malibu LS also uses the 205/65R16 radial size on a 16-inch rim. For this sub-model, the practical decision is less about multiple fitments and more about verifying that the car remains on its intended wheel size before choosing a replacement tire.
The 2018 Chevrolet Malibu LT can use more than one radial tire size, so this trim requires closer wheel confirmation than the rest of the range. Tire choice starts with identifying whether the car has 17-, 18-, or 19-inch wheels, then comparing the available series and sidewall treatments within that exact fitment.
The 2018 Chevrolet Malibu Premier uses larger-wheel radial fitments, with the exact tire depending on whether the car carries the 18-inch or 19-inch setup. That makes wheel diameter the first thing to verify before comparing blackwall tire options across the available performance-oriented 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.

These 2018 Chevrolet Malibu tire FAQs focus on exact size by sub-model, wheel diameter, product selection, appearance choices, and the fitment checks that matter before road use.
Tire Size & Fitment
What tire size fits a 2018 Chevrolet Malibu?
A 2018 Chevrolet Malibu can use 205/65R16, 225/55R17, 245/45R18, or 245/40R19, depending on the sub-model and wheel package. The L and LS use 205/65R16, the Hybrid uses 225/55R17, the LT can use 225/55R17, 245/45R18, or 245/40R19, and the Premier uses 245/45R18 or 245/40R19.
The practical takeaway is that this Malibu does not have one universal tire size across every trim. Checking the exact sub-model helps, but confirming the actual wheel diameter on the car is even more important, especially on LT and Premier cars where more than one size may apply.
What size rim does a 2018 Chevrolet Malibu use?
The 2018 Chevrolet Malibu uses several rim diameters depending on trim: 16-inch, 17-inch, 18-inch, and 19-inch. Those diameters pair with 205/65R16, 225/55R17, 245/45R18, and 245/40R19 tire sizes respectively, all in radial construction.
Rim diameter is the first fitment detail to verify before ordering replacement tires, because the tire must match the wheel's bead seat diameter exactly. Looking at the sidewall size already on the car and physically confirming the wheel package is especially useful if the Malibu has had wheels changed since new.
Why does the 2018 Chevrolet Malibu have more than one tire size?
The 2018 Chevrolet Malibu has more than one tire size because different sub-models and wheel packages use different wheel diameters. Some trims keep a single fitment, such as the L, LS, and Hybrid, while the LT and Premier can be equipped with larger wheel options that move the car into different tire sizes.
That means tire selection starts with configuration, not brand preference. Two Malibus from the same model year can need different tires even when they look similar at a glance, so checking the trim level and then confirming whether the car has 16-, 17-, 18-, or 19-inch wheels avoids a common fitment mistake.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Chevrolet Malibu?
Start with the correct tire size for the exact 2018 Chevrolet Malibu trim and wheel diameter, then compare the available radial options within that fitment. Useful selection points include tire series, sidewall style, rim-width compatibility, load figures where stated, and whether the goal is a standard blackwall presentation or something more visually distinctive.
The right choice depends on how the car is used and how closely the appearance should match the owner's vision for it. A 17-inch Malibu opens the door to blackwall, wide whitewall, or redline looks, while 18- and 19-inch applications lean more toward contemporary blackwall performance-oriented choices.
What sidewall styles are available for 2018 Chevrolet Malibu tires?
Sidewall style depends on the tire size. Blackwall choices are available across the supported Malibu sizes shown here, while 225/55R17 also offers wide whitewall and redline versions through the Silvertown Radial line, giving that particular fitment a broader appearance range than the larger wheel sizes.
That matters if the Malibu is being personalized rather than simply maintained with a standard late-model look. Buyers using 17-inch wheels have more room to shape the visual character of the car, while 18- and 19-inch applications stay focused on blackwall radials that suit a more contemporary presentation.
What brands offer tires for the 2018 Chevrolet Malibu?
BFGoodrich supplies tire options for the 17-, 18-, and 19-inch Malibu fitments shown here, and Nitto appears in the 245/45R18 size. Within those brand offerings, the available lines include g-Force Comp 2 AS, g-Force Sport Comp 2, g-Force Phenom T/A, Silvertown Radial, and Nitto NT555 G2.
Brand choice only comes after the correct size is confirmed, since Malibu fitment varies by trim and wheel package. Once the size is settled, comparing brands and series helps narrow the selection by intended use, visual style, and wheel-width compatibility rather than treating every available tire as interchangeable.
Restoration & Appearance
Which tire should I choose for a period-style 2018 Chevrolet Malibu?
A period-style look on a 2018 Chevrolet Malibu depends more on sidewall treatment than on changing away from the correct modern radial fitment. In the available choices shown here, 225/55R17 offers the broadest appearance flexibility because it includes Silvertown Radial options in wide whitewall and redline as well as conventional blackwall designs.
That makes the 17-inch setup the most appearance-driven path for an owner who wants something less modern-looking without leaving the proper size family. The main thing to confirm is that the Malibu actually uses the 225/55R17 fitment, since sidewall style should follow the correct wheel and tire size, not replace it.
How does tire construction affect the appearance of a restored 2018 Chevrolet Malibu?
On a 2018 Chevrolet Malibu, construction is straightforward because the supported primary fitments are radial tires. The appearance difference comes less from bias-ply versus radial and more from tire series and sidewall treatment, particularly on 225/55R17 where blackwall, wide whitewall, and redline versions create very different visual results.
That means a restoration-oriented or custom look is still possible without moving outside the Malibu's modern tire construction. Matching the exact size first keeps the proportions tied to the intended wheel package, while the chosen sidewall style and series shape whether the final look feels understated, sporty, or more nostalgic.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Chevrolet Malibu?
Yes. Wheel changes, suspension alterations, lowering, and body modifications can all affect tire fitment on a 2018 Chevrolet Malibu even when the replacement tire matches one of the original size families. The car may have left the factory with 16-, 17-, 18-, or 19-inch wheels, so any later changes can alter clearance and compatibility.
That is why the wheel currently on the car matters more than assumptions about trim alone. A buyer should confirm wheel diameter, wheel width, and the tire size already installed, then check for steering and fender clearance before moving to a different Malibu fitment or replacing an aftermarket setup.
What should I inspect before driving a 2018 Chevrolet Malibu on new tires?
Before driving a 2018 Chevrolet Malibu on new tires, inspect the wheels for damage, confirm the tire size matches the wheel diameter, and make sure all four tires are in sound condition and properly inflated. It also helps to look over the valve stems, check for uneven suspension-related wear, and verify that nothing is rubbing at full steering lock.
A quick road-use check is especially important on trims with larger wheel packages, since 18- and 19-inch fitments leave less room for size mistakes. After installation, recheck pressure, listen for vibration, and inspect the sidewalls and inner clearances again once the car has been driven a short distance.
How often should tires on a 2018 Chevrolet Malibu be inspected?
Tires on a 2018 Chevrolet Malibu should be inspected regularly for pressure loss, tread wear, cuts, bulges, and sidewall cracking, especially if the car sits for long periods or is driven on rough pavement. Even a newer-style radial tire can develop issues that are easy to miss until vibration, uneven wear, or air loss appears.
Monthly visual checks are a sensible routine, with a closer inspection before longer trips and after any impact with potholes or curbs. Owners should also keep an eye on wear patterns, since unusual inner or outer edge wear can point to alignment, suspension, or wheel issues rather than a problem with the tire alone.
