The 2025 Chevrolet Trucks Equinox EV brings Chevrolet’s compact crossover formula into the electric era, blending familiar utility with the packaging and visual stance buyers expect from a modern EV. It sits in a market where wheel and tire choice affects not only appearance, but also everyday ride quality and fitment confidence. For this exact model, tire selection centers on two radial sizes, 245/55R19 and 275/40R21, with fitment varying by sub-model and wheel package. That creates a clear decision between a 19-inch and 21-inch setup rather than a bias-ply-versus-radial question. Before choosing a replacement tire, confirm the exact trim and wheel diameter already on the vehicle.
Which Tire Size Is Right for The 2025 Chevrolet Trucks Equinox EV
The 2025 Chevrolet Trucks Equinox EV uses two primary tire sizes, and the first thing to confirm is wheel diameter. Fitment changes by sub-model and wheel package, with 245/55R19 on a 19-inch rim and 275/40R21 on a 21-inch rim. Once that is verified, the real comparison becomes overall tire character, brand availability, and whether the replacement matches the vehicle’s existing setup and intended use.
245/55R19 is a metric radial size in which 245 identifies section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 19 is the wheel diameter in inches. On the 2025 Chevrolet Trucks Equinox EV, this size belongs to a 19-inch wheel package and keeps the selection focused on modern radial replacement fitment. Its dimensions place it close in overall diameter to the available 21-inch option while using a different wheel size. This is the size to evaluate when the vehicle is equipped with 19-inch wheels and the goal is a proper replacement within that setup.
275/40R21 is a metric radial size where 275 is the nominal section width in millimeters, 40 is the aspect ratio, R marks radial construction, and 21 is the wheel diameter in inches. For the 2025 Chevrolet Trucks Equinox EV, this size is tied to the 21-inch wheel fitment and gives the vehicle a distinctly larger wheel-and-tire presentation. Its lower profile and wider section make wheel confirmation especially important before replacement. This is the size to use when the Equinox EV already carries the 21-inch setup and the replacement needs to match that configuration.
Sub-model fitment matters on the 2025 Chevrolet Trucks Equinox EV because tire size is not uniform across the lineup. The LT can use either a 19-inch or 21-inch tire package, while the RS uses the 21-inch setup, so identifying the exact trim and wheel diameter comes first.

2025 Chevrolet Trucks Equinox EV LT
The 2025 Chevrolet Trucks Equinox EV LT can be equipped with either the 245/55R19 radial size or the 275/40R21 radial size, depending on the wheel package on the vehicle. That means tire selection starts with confirming whether the LT has 19-inch or 21-inch wheels before comparing replacement options.
The 2025 Chevrolet Trucks Equinox EV RS uses the 275/40R21 radial fitment, placing it on the larger 21-inch wheel setup. Tire shopping for the RS is therefore less about choosing between primary sizes and more about matching the existing wheel diameter and overall tire specifications.
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.
Frequently Asked Questions
These FAQs focus on the exact tire sizes used on the 2025 Chevrolet Trucks Equinox EV, how LT and RS fitment differs, what the size markings mean, and what to inspect before putting replacement tires into regular road use.
Tire Size & Fitment
What tire size fits a 2025 Chevrolet Trucks Equinox EV?
The 2025 Chevrolet Trucks Equinox EV uses two primary tire sizes: 245/55R19 and 275/40R21. Both are radial tire sizes, and the correct one depends on the vehicle’s sub-model and wheel package rather than a broad year-make-model assumption.
The LT can use either size, while the RS uses 275/40R21. The practical step is to confirm the actual wheel diameter on the vehicle before choosing a replacement tire, because a 19-inch tire and a 21-inch tire are not interchangeable even though their overall diameters are relatively close.
What size rim does a 2025 Chevrolet Trucks Equinox EV use?
A 2025 Chevrolet Trucks Equinox EV uses either a 19-inch or 21-inch rim, depending on the tire size installed. The 245/55R19 tire fits a 19-inch rim, while the 275/40R21 tire fits a 21-inch rim.
Checking the wheel diameter matters before anything else because tire size starts with matching the rim correctly. Looking at the sidewall marking on the current tire is often the quickest confirmation, and it is also wise to verify that the vehicle has not been changed to a different wheel package than it originally carried.
Why does the 2025 Chevrolet Trucks Equinox EV have more than one tire size?
The 2025 Chevrolet Trucks Equinox EV has more than one tire size because fitment varies by trim and wheel package. The LT can be equipped with either 245/55R19 or 275/40R21, while the RS uses 275/40R21.
That means the right replacement is tied to the exact configuration already on the vehicle, not simply the model name. Before buying tires, confirm both the sub-model and the actual wheel diameter, especially if the Equinox EV was purchased used or may have received accessory wheels after it left the showroom.
Choosing the Right Tire
What should I consider when choosing a 245/55R19 or 275/40R21 tire for a 2025 Chevrolet Trucks Equinox EV?
Start with the exact size already fitted to the vehicle, because the 2025 Chevrolet Trucks Equinox EV uses either 245/55R19 or 275/40R21 depending on trim and wheel package. The correct replacement must match that size and the corresponding 19-inch or 21-inch rim diameter.
After size is confirmed, compare the tire’s overall specifications against how the vehicle is used. Daily commuting, seasonal mileage, ride preference, and any wheel changes all matter. A careful match keeps the replacement aligned with the existing setup instead of introducing avoidable clearance, wheel-fitment, or handling questions.
How do I choose between the available 2025 Chevrolet Trucks Equinox EV tire sizes?
Most owners do not choose freely between the two primary sizes, because the vehicle’s wheel package determines the correct tire. A 19-inch wheel calls for 245/55R19, while a 21-inch wheel calls for 275/40R21.
The useful comparison is not which size seems more appealing on paper, but which one matches the wheels actually on the Equinox EV. If the vehicle has already been changed from stock wheels, verify wheel diameter and the current tire markings before replacing anything so the new tires remain consistent with the setup in service.
What does 275/40R21 mean on a 2025 Chevrolet Trucks Equinox EV?
275/40R21 is a modern metric radial tire size. The 275 is the nominal section width in millimeters, 40 is the aspect ratio, R means radial construction, and 21 identifies the wheel diameter in inches.
Reading the full size matters because each part affects fitment. On a 2025 Chevrolet Trucks Equinox EV, that final 21 means the tire belongs on a 21-inch wheel, not a 19-inch one. Matching the complete size code is the safest way to avoid ordering a tire that is dimensionally wrong for the vehicle’s existing wheels.
Restoration & Appearance
Does correct tire fitment matter for a 2025 Chevrolet Trucks Equinox EV restoration or appearance-focused build?
Yes. Even on a modern vehicle like the 2025 Chevrolet Trucks Equinox EV, correct tire fitment matters because wheel diameter, sidewall profile, and section width all shape the vehicle’s stance and visual balance. Using the proper 245/55R19 or 275/40R21 size keeps that presentation aligned with the wheel package.
Appearance-focused changes should still start with fitment discipline. A different wheel package can alter how the Equinox EV sits and looks, but the replacement tire still needs to match the actual rim diameter and clear the body and suspension properly. Style works best when the tire choice respects the vehicle’s physical setup.
How does tire construction affect the appearance of a 2025 Chevrolet Trucks Equinox EV?
On the 2025 Chevrolet Trucks Equinox EV, both primary tire sizes are modern radial fitments, so construction is not a bias-ply-versus-radial styling decision. The visible appearance difference comes more from wheel diameter, tire width, and sidewall height than from a change in tire construction type.
That makes the 19-inch and 21-inch setups visually distinct even when overall tire diameter stays close. A 245/55R19 presents more sidewall, while a 275/40R21 gives a wider, lower-profile look. Any appearance-based change should be evaluated against wheel compatibility and clearance, not style alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Chevrolet Trucks Equinox EV?
Yes. Modifications can affect tire fitment on a 2025 Chevrolet Trucks Equinox EV, especially if they involve aftermarket wheels, changes in wheel width, suspension height adjustments, or body alterations. Those changes can influence clearance even when the tire size itself looks close to the original setup.
A modified Equinox EV should be checked for steering clearance, fender space, and suspension travel before replacement tires go into service. Wheel diameter still has to match the tire exactly, and any change from the original package is worth measuring carefully rather than assuming the previous owner’s setup answers every fitment question.
What should I inspect before driving a 2025 Chevrolet Trucks Equinox EV on new tires?
Before driving a 2025 Chevrolet Trucks Equinox EV on new tires, confirm that the installed size matches the vehicle’s wheel diameter and trim setup. It is also smart to inspect inflation pressure, wheel condition, valve stems, and basic clearance around the suspension and body.
A short initial road check can help catch rubbing, vibration, or irregular behavior before normal use resumes. Rechecking pressure after the first period of use is worthwhile, and any sign of contact, uneven wear, or persistent air loss should be addressed early so the new tires start their service life correctly.
How often should tires on a 2025 Chevrolet Trucks Equinox EV be inspected?
Tires on a 2025 Chevrolet Trucks Equinox EV should be inspected regularly, not only when replacement time arrives. Routine checks should include pressure, tread condition, cuts, bulges, cracking, and any unusual wear pattern that may suggest alignment or suspension concerns.
Monthly visual checks are a sensible habit, and the tires deserve another look before a longer trip or after any impact with potholes or road debris. A modern EV can put steady demand on its tires, so catching air loss, shoulder wear, or sidewall damage early helps preserve both fitment confidence and everyday drivability.
