The 2011 Chevrolet Trucks Equinox came from a period when midsize crossovers were expected to balance family-duty practicality with a more refined road feel than earlier truck-based SUVs. That matters when choosing tires, because this Equinox uses radial fitments in three modern metric sizes: 225/65R17, 235/55R18, and 235/55R19, depending on sub-model and wheel package. The main decision is less about vintage-style construction and more about confirming the exact wheel diameter and trim before selecting a tire. Once that is settled, the focus shifts to proper size, rim compatibility, intended use, and whether the vehicle remains stock or has been modified.
Which Tire Size Is Right for The 2011 Chevrolet Trucks Equinox
Three primary tire sizes apply to the 2011 Chevrolet Trucks Equinox, and they are tied to both sub-model and wheel diameter. The first step is confirming the exact trim and whether the vehicle is on 17-inch, 18-inch, or 19-inch wheels, since that determines whether it uses 225/65R17, 235/55R18, or 235/55R19. Once the wheel size is verified, the real decision becomes choosing the right tire within that fitment and making sure the current wheel and suspension setup still matches the intended size.
225/65R17 is a modern metric radial size in which 225 is the nominal section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2011 Chevrolet Trucks Equinox, this size serves as a primary fitment on 17-inch-wheel configurations rather than every version of the model. Available product choice in this size includes BFGoodrich with an RBL sidewall in the All Terrain TA KO2 series. It is the right size to evaluate when the Equinox is equipped with 17-inch wheels and the intended use leans toward a more rugged tire style.
235/55R18 is a modern metric radial size that uses a 235-millimeter nominal section width, a 55-series profile, and an 18-inch rim diameter. For the 2011 Chevrolet Trucks Equinox, this size applies to certain 18-inch-wheel LT and LTZ configurations, so it should not be selected until the wheel package is confirmed. Radial construction is standard here, matching the vehicle's contemporary crossover tire setup rather than an older bias-ply format. This size becomes the correct path when the vehicle's trim and wheel diameter point to the 18-inch fitment and the goal is to stay aligned with that wheel package.
235/55R19 follows the same modern metric radial format, with a 235-millimeter nominal section width, a 55-series aspect ratio, and a 19-inch rim diameter. On the 2011 Chevrolet Trucks Equinox, this size is tied to the LTZ 19 Inch Option, making wheel confirmation especially important before any tire selection begins. Its role is specific to that larger-diameter factory-style wheel setup rather than the broader Equinox range. Buyers looking at this size should verify that the vehicle still carries the correct 19-inch wheels and has not been changed to a different diameter through later wheel swaps.
Tire fitment on the 2011 Chevrolet Trucks Equinox varies by sub-model and wheel package rather than staying uniform across the full lineup. Checking the exact trim matters here, because the difference between 17-inch, 18-inch, and 19-inch wheels determines which primary tire size belongs on the vehicle.

2011 Chevrolet Trucks Equinox LS
The 2011 Chevrolet Trucks Equinox LS uses the 225/65R17 radial fitment. That makes tire selection fairly straightforward, with the main task being confirmation that the vehicle is still on its 17-inch wheel setup and has not been changed to a different diameter.
The 2011 Chevrolet Trucks Equinox LT can use either 225/65R17 or 235/55R18 depending on the wheel package. Tire selection starts with confirming whether the vehicle is on 17-inch or 18-inch rims, then choosing a tire that matches that specific setup.
The 2011 Chevrolet Trucks Equinox LTZ also appears with either 225/65R17 or 235/55R18 in standard trim coverage. That means the trim badge alone is not enough, and the wheel diameter should be checked before settling on a replacement tire size.
2011 Chevrolet Trucks Equinox LTZ (19 Inch Option)
The 2011 Chevrolet Trucks Equinox LTZ (19 Inch Option) uses the 235/55R19 radial fitment. Tire selection for this version centers on retaining the 19-inch setup and confirming that the current wheels and overall vehicle configuration still match that package.
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.

Owners of a 2011 Chevrolet Trucks Equinox usually need to confirm trim, wheel diameter, and the correct metric radial size before choosing a tire. These FAQs focus on size fitment, rim selection, product choice, modifications, and pre-drive inspection points.
Tire Size & Fitment
What tire size fits a 2011 Chevrolet Trucks Equinox?
The 2011 Chevrolet Trucks Equinox uses three primary tire sizes: 225/65R17, 235/55R18, and 235/55R19. The correct size depends on the sub-model and wheel package, not simply the model name alone. LS uses 225/65R17, certain LT and LTZ versions use either 225/65R17 or 235/55R18, and the LTZ with the 19 Inch Option uses 235/55R19.
The practical step is to confirm the wheel diameter actually on the vehicle before ordering tires. Many Equinox models from this year overlap by trim name, so the safest approach is to check the current tire sidewall and wheel size, then compare that with the intended stock-style fitment if the vehicle has had wheels changed.
What size rim does a 2011 Chevrolet Trucks Equinox use?
A 2011 Chevrolet Trucks Equinox can use 17-inch, 18-inch, or 19-inch rims, depending on the exact sub-model and wheel option. The 225/65R17 fitment uses a 17-inch rim, the 235/55R18 fitment uses an 18-inch rim, and the 235/55R19 fitment uses a 19-inch rim.
Rim diameter should be confirmed before anything else because tire size cannot be chosen independently of the wheel. An Equinox that now wears aftermarket wheels or a later wheel swap may not still match its original trim-based fitment, so checking the actual rim size on the vehicle prevents choosing the right tire size for the wrong wheel.
Do all 2011 Chevrolet Trucks Equinox sub-models use the same tire size?
No, the 2011 Chevrolet Trucks Equinox does not use one tire size across every sub-model. LS uses 225/65R17, LT and LTZ can use either 225/65R17 or 235/55R18, and the LTZ with the 19 Inch Option uses 235/55R19. Sub-model and wheel package both matter on this application.
That variation means trim level alone may not settle the question if the vehicle is an LT or LTZ. Wheel diameter is the final check, and it is especially important on used vehicles where wheels may have been replaced. Matching the tire to the actual wheel on the vehicle is more useful than relying only on a badge or assumption.
Choosing the Right Tire
What should I consider when choosing a 225/65R17 tire for a 2011 Chevrolet Trucks Equinox?
Start by confirming that 225/65R17 is the correct fitment for the specific 2011 Chevrolet Trucks Equinox and not one of the 18-inch or 19-inch setups. After that, compare construction, intended use, sidewall style, load information, and rim-width compatibility. In available product coverage for this size, BFGoodrich offers a radial All Terrain TA KO2 with an RBL sidewall.
Selection should reflect how the Equinox is actually driven. A more aggressive all-terrain design may suit owners who want a tougher look or added versatility, but it still needs to match the wheel width and overall setup. Checking suspension condition, ride expectations, and whether the vehicle remains stock helps narrow the choice without forcing the wrong tire style onto the vehicle.
What sidewall styles are available for 2011 Chevrolet Trucks Equinox tires?
Current product coverage for the 2011 Chevrolet Trucks Equinox includes an RBL sidewall style in 225/65R17. RBL is a practical appearance choice that gives the tire a more defined sidewall presentation than a plain blackwall, while still remaining within a modern radial format suited to this crossover.
Sidewall style should be chosen as part of the overall look and use of the vehicle, not as a stand-alone detail. The more important checks remain correct size, wheel diameter, and compatibility with the wheel width. Once those are settled, sidewall appearance can help shape whether the finished setup feels more understated, utility-oriented, or visually rugged.
What brands offer tires for the 2011 Chevrolet Trucks Equinox?
Available product coverage for the 2011 Chevrolet Trucks Equinox includes BFGoodrich in 225/65R17. The listed tire is part of the All Terrain TA KO2 series and uses radial construction, which matches the Equinox's modern tire format rather than an older collector-era bias-ply application.
Brand is only one part of the decision. It still makes sense to confirm that the tire's size, load capability, and rim-width range suit the vehicle's wheel setup and intended use. An owner looking for a stock-style road-focused replacement may evaluate differently than one wanting a more assertive all-terrain look on a 17-inch Equinox.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Chevrolet Trucks Equinox?
A period-style approach on a 2011 Chevrolet Trucks Equinox starts with using the correct original fitment family for the specific wheel package: 225/65R17, 235/55R18, or 235/55R19. Since this is a modern crossover, the visual character comes more from staying with the proper metric radial size and wheel diameter than from choosing vintage-style construction.
Appearance still matters, especially on a clean, unmodified example. A buyer should first preserve the correct overall stance by matching the proper wheel size, then compare sidewall presentation and tread style within that fitment. If the vehicle has been altered with aftermarket wheels or a different suspension height, restoring the original look begins with correcting those changes.
Does correct tire fitment matter for a 2011 Chevrolet Trucks Equinox restoration?
Yes, correct tire fitment matters because the 2011 Chevrolet Trucks Equinox was offered with more than one wheel-and-tire combination. Using the right size for the exact trim and wheel package helps preserve the intended proportions of the vehicle and avoids an appearance that looks mismatched to the body and wheel openings.
That matters even more on an LT or LTZ, where more than one primary size can appear. A restoration-minded owner should confirm whether the vehicle belongs on 17-inch, 18-inch, or 19-inch wheels before choosing tires. Keeping the fitment aligned with the proper setup supports both appearance and practical compatibility with the existing wheel hardware.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Chevrolet Trucks Equinox?
Yes, modifications can change tire fitment on a 2011 Chevrolet Trucks Equinox even when the original size is known. Aftermarket wheels, changes in wheel width, altered offset, suspension lowering, lift components, or body changes can all affect how a 225/65R17, 235/55R18, or 235/55R19 tire sits and clears the vehicle.
The best approach is to inspect the actual wheel diameter and overall setup already on the vehicle before choosing a replacement tire. Clearance at full steering lock, suspension travel, and spacing near the fender and inner body should all be considered. That extra verification matters most when the Equinox no longer appears to be on its original wheel package.
What should I inspect before driving a 2011 Chevrolet Trucks Equinox on new tires?
Before driving a 2011 Chevrolet Trucks Equinox on new tires, check that the tire size matches the wheel diameter and that the tires are properly seated and inflated. It also makes sense to inspect the wheels for damage, verify lug hardware condition and torque, and look over the suspension and steering components for wear that could affect tire behavior.
A short road test should include listening for rubbing, feeling for vibration, and confirming stable steering response. Recheck inflation after the first drives, and keep an eye on tread wear as the tires begin service. On a vehicle that has sat for long periods, checking alignment condition and old suspension bushings is just as important as the tires themselves.
How often should tires on a 2011 Chevrolet Trucks Equinox be inspected?
Tires on a 2011 Chevrolet Trucks Equinox should be inspected regularly, not only when tread looks worn. Pressure, tread condition, cuts, punctures, bulges, and uneven wear should all be checked as part of routine ownership. Vehicles that see lighter use still need inspection because age, storage conditions, and slow air loss can affect tire condition over time.
Monthly pressure checks are a sensible habit, and a closer visual inspection before longer drives adds another layer of protection. It is also worth checking the inside sidewall area when possible, since damage is not always obvious from the outside. Consistent inspection helps catch alignment, suspension, or wheel issues before they shorten tire life.
