The 2026 Chevrolet Trucks Colorado sits in the modern midsize pickup space where trim level matters as much as the truck itself, especially for owners balancing daily use, trail work, and appearance. On this model, tire fitment ranges from road-oriented metric radials to larger all-terrain sizes used on the more off-road-focused versions. Depending on sub-model, the Colorado uses 17-, 18-, or 20-inch radial tires, so identifying the exact trim is the first step. Available product choices lean toward BFGoodrich All-Terrain T/A KO2 fitments with raised white letter styling in several sizes. That makes this page less about broad brand shopping and more about matching the truck's wheel setup, intended use, and stance.
Which Tire Size Is Right for The 2026 Chevrolet Trucks Colorado
The 2026 Chevrolet Trucks Colorado uses eight primary tire sizes, and they vary by sub-model and wheel diameter. Every fitment here is a radial, but the truck can be equipped with 17-inch, 18-inch, or 20-inch wheels depending on version. The first step is confirming the exact sub-model and wheel size on the truck, since that determines which metric radial size belongs on it.
255/65R17 is a metric radial size where 255 is the section width in millimeters, 65 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches. On the 2026 Chevrolet Trucks Colorado, this size serves trims that use a 17-inch wheel and a moderate overall tire profile. Available choices in this size include a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. It is the size to evaluate when the truck needs to keep its original 17-inch wheel setup while adding a more aggressive all-terrain presentation.
265/65R18 is a metric radial size with a 265-millimeter section width, a 65-series profile, and fitment for an 18-inch rim. This size suits Colorado configurations that use an 18-inch wheel while maintaining a taller sidewall than lower-profile 20-inch fitments. Product details are not the same across every Colorado size, so this fitment should be chosen by exact trim and wheel setup rather than by appearance alone. It is a useful match when the truck's current wheel diameter and factory-style tire proportions point to an 18-inch radial with added sidewall height.
275/60R20 is a metric radial tire with a 275-millimeter section width, a 60-series profile, and a 20-inch rim diameter. On the 2026 Chevrolet Trucks Colorado, this size appears on specific configurations that use a larger wheel and a relatively shorter sidewall than the 17-inch and 18-inch alternatives. That changes the truck's visual stance and makes wheel confirmation especially important before selecting a tire. This size is the right one to investigate when the Colorado is already equipped with 20-inch wheels and trim-specific fitment points to this broader, lower-profile combination.
275/65R18 is a metric radial size combining a 275-millimeter section width with a 65-series profile on an 18-inch rim. Within the 2026 Chevrolet Trucks Colorado range, it represents one of the more substantial 18-inch fitments and is available as a BFGoodrich All-Terrain T/A KO2 with raised white letter styling. That gives buyers a clear all-terrain option in this size with published rim-width compatibility and load information tied to the tire. It is the size to review when an 18-inch Colorado setup calls for a wider, more truck-oriented tire rather than a narrower street-focused fitment.
265/60R18 is a metric radial tire size where 265 describes section width in millimeters, 60 is the aspect ratio, and 18 is the wheel diameter in inches. On the 2026 Chevrolet Trucks Colorado, this size belongs to certain 18-inch-wheel configurations and carries a slightly lower profile than the 265/65R18 alternative. That makes it important not to assume that all 18-inch Colorado wheels use the same tire dimensions. This is the size to confirm when the truck has an 18-inch setup but needs the proportions tied to this specific trim-level fitment rather than a taller sidewall version.
255/55R20 is a metric radial size with a 255-millimeter section width, a 55-series sidewall profile, and a 20-inch rim diameter. For the 2026 Chevrolet Trucks Colorado, it is one of the lower-profile primary fitments and depends on a 20-inch wheel already being in place. Compared with the truck's taller 17-inch and 18-inch options, this size changes both the look and sidewall height, so wheel and trim confirmation come first. It is the fitment to consider when the Colorado's exact sub-model uses 20-inch wheels and calls for a more contemporary, road-oriented tire profile.
285/70R17 is a metric radial tire with a 285-millimeter section width, a 70-series profile, and fitment for a 17-inch rim. On the 2026 Chevrolet Trucks Colorado, this is the ZR2-size fitment and it has available BFGoodrich All-Terrain T/A KO2 choices with raised white letter sidewalls in more than one load specification. Those product differences matter because rim-width compatibility, load capacity, and tire weight can vary within the same nominal size. This is the size to inspect closely when the truck is an off-road-focused Colorado running 17-inch wheels and a larger all-terrain footprint.
315/70R17 is a metric radial size that uses a 315-millimeter section width, a 70-series profile, and a 17-inch rim. Within the 2026 Chevrolet Trucks Colorado lineup, it is the most substantial primary fitment shown here and belongs to the ZR2 Bison Edition. Its larger dimensions make exact wheel compatibility and clearance verification more important than with the smaller Colorado tire sizes. This is the fitment to focus on when the truck is the Bison-spec version and needs a tire that matches its specialized 17-inch setup rather than a standard Colorado wheel-and-tire package.
Tire fitment varies across the 2026 Chevrolet Trucks Colorado lineup, and some sub-models use more than one primary size. Checking the exact trim matters because wheel diameter, sidewall profile, and overall tire dimensions change from one Colorado configuration to another.

2026 Chevrolet Trucks Colorado LT
The 2026 Chevrolet Trucks Colorado LT uses a single 255/65R17 radial fitment, which makes size identification straightforward once the trim is confirmed. Tire selection then centers on choosing a suitable 17-inch radial that matches the truck's intended use and wheel setup.
The 2026 Chevrolet Trucks Colorado Trail Boss can use multiple tire sizes, including both 18-inch and 20-inch fitments. That means the actual wheel package on the truck needs to be verified before comparing tires, especially if appearance or ride-profile differences matter.
2026 Chevrolet Trucks Colorado Trail Boss w/Midnight Pkg.
The 2026 Chevrolet Trucks Colorado Trail Boss w/Midnight Pkg. uses a single 275/60R20 radial fitment. With size choice narrowed down, the main concern becomes matching the 20-inch wheel setup and preserving the truck's intended stance and clearance.
The 2026 Chevrolet Trucks Colorado WT uses two different primary tire sizes depending on configuration, so trim alone is not enough without confirming the wheel package. The right tire choice starts with checking whether the truck is equipped with its 17-inch or 18-inch setup.
The 2026 Chevrolet Trucks Colorado Z71 uses either an 18-inch or 20-inch radial fitment depending on configuration. Tire selection should begin with wheel-diameter confirmation, then move to the sidewall profile and overall look that suit the truck's current setup.
The 2026 Chevrolet Trucks Colorado ZR2 uses a 285/70R17 radial tire, a larger 17-inch fitment aligned with this truck's off-road-focused setup. Choosing within that size means comparing load specification, rim-width compatibility, and the kind of all-terrain presentation desired.
The 2026 Chevrolet Trucks Colorado ZR2 Bison Edition uses a 315/70R17 radial tire, the largest primary fitment in the Colorado range shown here. Selection should stay closely tied to the truck's exact wheel setup and available clearance before moving to brand or tread-style considerations.
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.

Available product coverage centers on select Colorado sizes, with BFGoodrich All-Terrain T/A KO2 options in raised white letter form. Where more than one product appears in the same size, comparing load specification, rim-width range, and tire weight becomes more important than simply matching the size code.
These FAQs focus on 2026 Chevrolet Trucks Colorado tire sizing by sub-model, wheel-diameter differences, radial fitment, available all-terrain choices, and the checks that matter before road use or any wheel-and-tire change.
Tire Size & Fitment
What tire size fits a 2026 Chevrolet Trucks Colorado?
The 2026 Chevrolet Trucks Colorado does not use one universal tire size. Depending on sub-model, primary sizes include 255/65R17, 265/65R18, 275/60R20, 275/65R18, 265/60R18, 255/55R20, 285/70R17, and 315/70R17, and every one of them is a radial fitment.
The correct choice depends first on the exact trim and wheel package already on the truck. A Colorado LT, WT, Z71, Trail Boss, ZR2, or ZR2 Bison Edition can point to different wheel diameters and tire proportions, so checking the current tire sidewall and wheel size before ordering helps avoid choosing the right brand in the wrong fitment.
What size rim does a 2026 Chevrolet Trucks Colorado use?
The 2026 Chevrolet Trucks Colorado uses 17-inch, 18-inch, and 20-inch rim diameters across the lineup. Tire sizes such as 255/65R17, 285/70R17, and 315/70R17 fit 17-inch wheels, several other Colorado sizes fit 18-inch wheels, and 275/60R20 and 255/55R20 fit 20-inch wheels.
Rim diameter is the first fitment detail to confirm because a tire for a 17-inch wheel cannot be mounted on an 18-inch or 20-inch rim. Once the wheel diameter is confirmed, the next step is matching the exact width and profile called for by the truck's trim and current wheel-and-suspension setup.
Do all 2026 Chevrolet Trucks Colorado sub-models use the same tire size?
No, Colorado sub-models do not all share one tire size. The LT uses 255/65R17, the ZR2 uses 285/70R17, the ZR2 Bison Edition uses 315/70R17, and trims such as WT, Z71, and Trail Boss can use more than one primary size depending on configuration.
That variation means trim identification matters before comparing tread style, sidewall treatment, or load specification. Two trucks may both be 2026 Colorados yet still require different wheel diameters and different tire proportions, so the safest starting point is to confirm the exact sub-model and inspect the wheel-and-tire package already on the truck.
Choosing the Right Tire
What should I consider when choosing a 2026 Chevrolet Trucks Colorado tire?
Start with the exact size and wheel diameter used by the truck's sub-model, because the 2026 Chevrolet Trucks Colorado spans 17-inch, 18-inch, and 20-inch fitments. Every primary size here is a radial, so the main choice is not bias-ply versus radial, but selecting the correct dimensions and intended tire character for the trim.
After size is confirmed, compare the truck's actual use with the tire's specifications and appearance. A Colorado used for trail work may call for a different approach than one driven mainly on pavement, and details such as rim-width range, load capacity, tire weight, and sidewall style can all influence which option makes the most sense.
What sidewall styles are available for 2026 Chevrolet Trucks Colorado tires?
Among the available product choices shown for the 2026 Chevrolet Trucks Colorado, the sidewall style is RWL, or raised white letter. That appearance is offered on BFGoodrich All-Terrain T/A KO2 tires in the covered Colorado sizes, giving certain 17-inch and 18-inch fitments a more traditional truck-oriented look.
Sidewall style affects appearance more than fitment, so it should be considered after the correct size and wheel diameter are confirmed. Raised white letter tires can change the visual character of the truck considerably, especially on ZR2 and other off-road-leaning trims, but the first requirement is still matching the tire to the Colorado's exact wheel and trim setup.
What brands offer tires for the 2026 Chevrolet Trucks Colorado?
The available products shown here for select 2026 Chevrolet Trucks Colorado sizes are from BFGoodrich. The featured series is the All-Terrain T/A KO2, and it appears in sizes including 255/65R17, 275/65R18, and 285/70R17 with radial construction and raised white letter sidewalls.
Brand choice only matters after the correct Colorado fitment has been pinned down, since not every tire is offered in every one of the truck's eight primary sizes. Once the size is confirmed, compare the BFGoodrich options by sidewall presentation, published load specification, rim-width range, and how closely the tire matches the way the truck is actually used.
Restoration & Appearance
Which tire should I choose for a period-style 2026 Chevrolet Trucks Colorado?
A period-style approach is less relevant for a 2026 Chevrolet Trucks Colorado than it would be for a vintage truck, but appearance still matters. The best starting point is the exact size used by the truck's sub-model, followed by a tire whose sidewall treatment and overall character suit the Colorado's intended look.
On trims with available BFGoodrich All-Terrain T/A KO2 coverage, raised white letter styling creates a more assertive truck presentation than a plain modern sidewall would. Even so, keeping the proper wheel diameter and overall fitment comes first, because appearance choices only work well when the tire's dimensions still match the truck's wheel package and clearance needs.
How does tire construction affect the appearance of a 2026 Chevrolet Trucks Colorado?
Construction is simple on the 2026 Chevrolet Trucks Colorado because all primary fitments shown here are radial tires. The visual difference comes less from radial versus bias-ply and more from the size itself, including wheel diameter, sidewall height, tread character, and whether the tire uses a raised white letter sidewall.
A 17-inch all-terrain fitment such as 285/70R17 gives the truck a different stance than a lower-profile 20-inch size, even though both are radial. Owners trying to preserve the truck's intended trim-specific look should confirm the exact sub-model fitment first, then choose a tire whose sidewall style and proportions support that appearance rather than altering it.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2026 Chevrolet Trucks Colorado?
Yes, modifications can affect tire fitment on a 2026 Chevrolet Trucks Colorado even when the tire size matches one used somewhere in the lineup. Wheel changes, offset differences, suspension lifts or lowering, and body or fender alterations can all change the space available for the tire.
A size that belongs on one Colorado trim should not be assumed to suit another truck that has been altered from its original wheel-and-suspension setup. Checking wheel diameter, wheel width, turning clearance, and room at the fenders before moving to a different Colorado size helps prevent rubbing or mismatch issues once the tires are mounted.
What should I inspect before driving a 2026 Chevrolet Trucks Colorado on new tires?
Before driving a 2026 Chevrolet Trucks Colorado on new tires, inspect the wheel diameter and tire size to confirm they match the truck's actual fitment. It also helps to check inflation pressure, valve condition, lug torque, sidewall condition, and visible clearance at the suspension, steering, and fender edges.
A short initial road test is useful because it can reveal vibration, rubbing, or steering issues that are easier to correct early. On larger Colorado fitments such as 285/70R17 or 315/70R17, taking an extra look at turning clearance and suspension travel is especially worthwhile before the truck goes into regular road or trail use.
How often should tires on a 2026 Chevrolet Trucks Colorado be inspected?
Tires on a 2026 Chevrolet Trucks Colorado should be inspected regularly, with a quick visual check before longer drives and a closer look at intervals throughout normal use. Pay attention to tread wear, pressure loss, cuts, bulges, punctures, and uneven wear patterns that may point to alignment or suspension issues.
Routine inspection matters even more on trucks that alternate between pavement and rougher terrain, since road hazards and off-road impacts can affect the tire or wheel without causing an immediate flat. Catching a pressure problem or sidewall injury early helps protect the tire itself and makes it easier to keep the Colorado tracking and wearing properly.
