The 2018 Chevrolet Trucks Equinox sits in the compact crossover segment where daily comfort, family use, and light utility all matter, so tire choice has a direct effect on how the vehicle feels on the road. This generation moved toward a more efficient, modern package, and its wheel-and-tire combinations reflect that approach. The 2018 Chevrolet Trucks Equinox uses radial tire fitments in three primary sizes: 225/65R17, 225/60R18, and 235/50R19. That means the key decision is less about vintage-style construction and more about matching the correct size to the exact trim and wheel diameter. Before selecting a tire, confirm the sub-model and the actual wheel setup on the vehicle.
Which Tire Size Is Right for The 2018 Chevrolet Trucks Equinox
The 2018 Chevrolet Trucks Equinox uses three primary tire sizes, and the correct one depends on the specific sub-model and wheel diameter. All three are radial fitments, but they are built around 17-inch, 18-inch, or 19-inch wheels. The first step is confirming which wheels are on the vehicle now, especially if the Equinox has changed trims, replacement wheels, or tire packages over time.
A 225/65R17 tire uses a 225-millimeter section width, a 65-series aspect ratio, radial construction, and a 17-inch rim. On the 2018 Chevrolet Trucks Equinox, this size serves as one of the primary modern radial fitments and is used on L, LS, and some LT models. The available product selection in this size includes a BFGoodrich All-Terrain T/A KO2 with an RBL sidewall, giving this fitment a more utility-oriented character than a typical highway crossover tire. This size is the right place to start when the Equinox carries 17-inch wheels and the goal is matching that wheel diameter correctly.
A 225/60R18 tire keeps the same 225-millimeter nominal width as the 17-inch option but pairs it with a 60-series profile and an 18-inch rim. This radial size is used on some LT models and on Premier trim applications for the 2018 Chevrolet Trucks Equinox. Its role in the fitment lineup is tied to the vehicle's 18-inch wheel package rather than a universal application across every Equinox. Buyers considering this size should confirm that the vehicle actually has 18-inch wheels and compare tire choices within that fitment based on intended road use, ride preference, and overall vehicle setup.
A 235/50R19 tire uses a wider 235-millimeter section width, a 50-series profile, radial construction, and a 19-inch rim. On the 2018 Chevrolet Trucks Equinox, this size applies to certain LT models and Premier configurations equipped with 19-inch wheels. Compared with the other primary sizes, it represents the largest wheel package in the Equinox range and should be chosen only when that wheel diameter matches the vehicle. This fitment is especially important to verify carefully on used or modified examples, since a trim change, wheel swap, or replacement package can easily alter what size belongs on the vehicle.
Sub-model fitment matters on the 2018 Chevrolet Trucks Equinox because tire size is not the same across the full lineup. Some trims use a single wheel-and-tire package, while others can carry more than one size, so identifying the exact trim and wheel diameter should come before choosing a replacement tire.

2018 Chevrolet Trucks Equinox L
The 2018 Chevrolet Trucks Equinox L uses a straightforward radial tire fitment tied to the 17-inch wheel package. That makes selection simpler, but the wheel diameter should still be confirmed before replacement, especially on vehicles that may have received later wheel swaps.
The 2018 Chevrolet Trucks Equinox LS follows the same basic radial fitment pattern as the L with a 17-inch wheel setup. Tire selection is mainly about staying with the correct size and choosing a product that suits how the vehicle is actually driven.
The 2018 Chevrolet Trucks Equinox LT is the trim where fitment needs the closest attention because it can use three different radial tire sizes. On an LT, wheel diameter should be verified first so the replacement tire matches the actual 17-inch, 18-inch, or 19-inch setup on the vehicle.
The 2018 Chevrolet Trucks Equinox Premier uses radial fitments tied to either 18-inch or 19-inch wheels. That means tire selection starts with confirming which wheel package is installed, then comparing products within the correct size rather than assuming all Premier models use the same tire.
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 FAQs focus on the tire sizes used on the 2018 Chevrolet Trucks Equinox, how they vary by trim and wheel diameter, and what to check when comparing products, maintaining tires, or replacing wheels.
Tire Size & Fitment
What tire size fits a 2018 Chevrolet Trucks Equinox?
The 2018 Chevrolet Trucks Equinox uses three primary tire sizes: 225/65R17, 225/60R18, and 235/50R19. All three are radial fitments, and the correct size depends on the sub-model and wheel package. L and LS models use 225/65R17, LT models can use all three sizes, and Premier models use 225/60R18 or 235/50R19.
The practical step is confirming the exact trim and the actual wheel diameter on the vehicle before buying tires. A used Equinox may have replacement wheels or a different trim wheel package than it left with, so the tire should match the wheel already installed rather than relying on trim name alone.
What size rim does a 2018 Chevrolet Trucks Equinox use?
The 2018 Chevrolet Trucks Equinox uses three rim diameters depending on configuration: 17-inch, 18-inch, and 19-inch. The 225/65R17 tire fits a 17-inch rim, the 225/60R18 fits an 18-inch rim, and the 235/50R19 fits a 19-inch rim. Rim diameter is one of the main fitment differences across the Equinox lineup.
Checking wheel diameter should happen before comparing tread style, brand, or load details. Looking at the sidewall markings on the current tires or measuring the wheel directly can prevent ordering the wrong size, especially on LT and Premier models where more than one wheel-and-tire package can be correct.
Do all 2018 Chevrolet Trucks Equinox sub-models use the same tire size?
No, the 2018 Chevrolet Trucks Equinox does not use one tire size across every sub-model. L and LS use 225/65R17, LT can use 225/65R17, 225/60R18, or 235/50R19, and Premier uses 225/60R18 or 235/50R19. The fitment changes with trim level and wheel package rather than staying the same through the entire model range.
That variation matters because a tire that belongs on one Equinox trim may be wrong for another simply due to wheel diameter. Buyers should verify the exact sub-model and then confirm the wheels currently on the vehicle, since prior owners sometimes change tire-and-wheel packages for appearance or replacement convenience.
Choosing the Right Tire
What should I consider when choosing a 225/65R17 tire for a 2018 Chevrolet Trucks Equinox?
Start with the basics: the vehicle must actually use the 225/65R17 size, and the wheel must be a 17-inch rim. Within that fitment, construction remains radial, so the next comparison points are the tire's intended use, sidewall style, load specification, rim-width compatibility, and how aggressive or road-focused the tread presentation needs to be.
A 2018 Chevrolet Trucks Equinox used mainly on pavement may call for a different product emphasis than one that sees rougher roads or more utility duty. Matching the tire to the vehicle's real use helps more than choosing by size alone, and it is wise to compare the product's stated rim-width range against the wheel already on the vehicle.
What sidewall styles are available for 2018 Chevrolet Trucks Equinox tires?
The available product assortment shown for the 2018 Chevrolet Trucks Equinox includes an RBL sidewall in 225/65R17. RBL generally refers to outlined raised black lettering rather than a plain blackwall or whitewall presentation. For buyers who care about appearance, sidewall treatment can noticeably change how a crossover or light truck-based vehicle looks.
Sidewall style should still come after the correct size and wheel diameter are confirmed. Once fitment is settled, appearance becomes a useful tie-breaker, especially when comparing tires that serve different purposes, such as a more utility-oriented all-terrain look versus a more subdued road-use presentation.
What brands offer tires for the 2018 Chevrolet Trucks Equinox?
The available product selection for the 2018 Chevrolet Trucks Equinox includes BFGoodrich in 225/65R17. That example is the All-Terrain T/A KO2, which gives the 17-inch fitment a truck-oriented option with its own series identity and sidewall presentation. Brand matters mainly as part of the broader product comparison rather than as a shortcut to fitment.
The right approach is to confirm size first, then compare what each available product brings in construction, sidewall style, rim-width compatibility, and intended use. On a vehicle with multiple possible sizes like the Equinox, choosing by brand name alone can lead to the wrong tire if the wheel diameter is not verified first.
Restoration & Appearance
How does tire construction affect the appearance of a 2018 Chevrolet Trucks Equinox?
On the 2018 Chevrolet Trucks Equinox, primary fitment is radial across all listed sizes, so construction does not create a bias-ply-versus-radial appearance decision the way it would on an older collector vehicle. Visual character comes more from wheel diameter, tire proportions, tread style, and sidewall treatment than from switching between different basic tire constructions.
That means the appearance decision is usually tied to whether the vehicle keeps its original-style wheel package or moves to a different wheel and tire combination. A 17-inch setup with an all-terrain style tire can look more rugged, while larger wheel packages tend to emphasize a more modern crossover stance.
Does correct tire fitment matter for a 2018 Chevrolet Trucks Equinox restoration or refurbishment?
Yes, correct tire fitment still matters on a 2018 Chevrolet Trucks Equinox even if the goal is refurbishment rather than a traditional vintage restoration. Using the right size preserves the intended relationship between tire, wheel, and body, and it helps the vehicle keep the visual balance associated with its original trim and wheel package.
Owners refreshing one of these vehicles should verify whether the Equinox still wears its proper 17-inch, 18-inch, or 19-inch wheels before ordering tires. If originality of appearance matters closely, trim-specific photos, window-sticker records, and marque-focused references can help confirm which wheel-and-tire package belongs on that particular vehicle.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Chevrolet Trucks Equinox?
Yes, modifications can affect tire fitment on a 2018 Chevrolet Trucks Equinox. Aftermarket wheels, changes in wheel width or offset, suspension lowering, spring changes, or body alterations can all change how a tire sits in the wheel opening. Even when the tire size matches one of the Equinox's factory-style fitments, the surrounding hardware may not.
That is why the current wheel-and-suspension setup matters more than assumptions based on trim alone. A vehicle with non-original wheels should have diameter, width, and clearance checked carefully before replacement, especially on steering lock and under compression where rubbing can show up even though the sidewall size looks familiar.
What should I inspect before driving a 2018 Chevrolet Trucks Equinox on new tires?
Before road use, inspect the wheel condition, confirm lug hardware is correct and properly seated, and make sure all four tires are the intended size for the vehicle's wheel package. It is also wise to check inflation pressure, valve stems, tread direction where applicable, and visible clearance around struts, fenders, and suspension components.
A short test drive should include listening for rubbing, vibration, or pull that did not exist before. Rechecking pressure and overall visual condition after the first drive is a smart step, particularly on an Equinox that has had wheel changes, recent suspension work, or tires installed after a long period of limited use.
How often should tires on a 2018 Chevrolet Trucks Equinox be inspected?
Tires on a 2018 Chevrolet Trucks Equinox should be inspected regularly, not just when tread looks low. A visual check for cuts, uneven wear, bulges, cracking, punctures, and pressure loss should become part of routine ownership, especially because crossovers often see mixed use that includes commuting, family travel, and occasional rough-road duty.
Inspection is especially important before longer drives and whenever the vehicle's handling starts to feel different. Looking at the shoulders and inner sidewalls can reveal issues that are easy to miss at a glance, and keeping pressure consistent helps preserve ride quality and the intended behavior of whichever Equinox tire size is installed.
