The 2025 Chevrolet Trucks Colorado sits in the current midsize pickup market as a truck that can range from everyday work duty to more trail-focused use, depending on trim. That matters at the tire level, because this Colorado does not rely on one universal fitment across the lineup. Tire sizes span from 255/65R17 through 315/70R17, all in radial construction, with 17-inch, 18-inch, and 20-inch rim diameters appearing across different sub-models. Available choices also lean heavily toward BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls in the covered sizes. Before choosing a tire, the key step is matching the exact trim and wheel diameter already on the truck.
Which Tire Size Is Right for The 2025 Chevrolet Trucks Colorado
Eight primary tire sizes apply to the 2025 Chevrolet Trucks Colorado, and they vary by sub-model and wheel diameter. Some trims use more than one factory-style size, so the first step is confirming the exact sub-model and whether the truck is on 17-inch, 18-inch, or 20-inch wheels. Once that is settled, the real comparison becomes tire type, load specification, sidewall presentation, and how the tire suits the truck's intended use.
255/65R17 is a metric radial size with a 255-millimeter nominal section width, a 65-series profile, and fitment for a 17-inch rim. On the 2025 Chevrolet Trucks Colorado, this size serves trims that use a moderate sidewall height and a 17-inch wheel package rather than a larger-diameter wheel. In the available product selection, it appears as a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. It is the right size to evaluate when the truck already carries the matching 17-inch wheel setup and you want to stay with that fitment style.
265/65R18 is a metric radial tire size that pairs a 265-millimeter section width with a 65-series aspect ratio on an 18-inch rim. For the 2025 Chevrolet Trucks Colorado, this size belongs to specific trims using an 18-inch wheel package and should be treated as a trim-dependent fitment rather than a lineup-wide choice. Its size places it among the taller 18-inch options used on this truck. It is the size to focus on when the Colorado has the correct 18-inch wheels and the existing trim calls for this particular balance of sidewall and wheel diameter.
275/60R20 is a metric radial size with a 275-millimeter width, a 60-series profile, and a 20-inch rim requirement. On the 2025 Chevrolet Trucks Colorado, it is one of the larger-wheel fitments and belongs only to certain configurations rather than every trim. Compared with the smaller-wheel sizes used elsewhere in the lineup, this fitment centers the tire choice around a 20-inch wheel package first. It is the right size to review when the truck already wears 20-inch wheels and you are matching the existing setup instead of converting from another wheel diameter.
275/65R18 is a metric radial tire with a 275-millimeter nominal width, a 65-series aspect ratio, and fitment for an 18-inch wheel. For the 2025 Chevrolet Trucks Colorado, this size appears on select trim applications that use a more substantial 18-inch tire package than narrower alternatives. The available product choice in this size is a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls and a published rim-width range. It makes sense to evaluate this size when the truck's trim and wheel package already call for it and you want to keep the same general fitment character.
265/60R18 is a metric radial size combining a 265-millimeter section width, a 60-series profile, and an 18-inch rim diameter. On the 2025 Chevrolet Trucks Colorado, it is one of the trim-specific 18-inch fitments and should be matched to the truck's actual wheel package before anything else. Its sizing places it in a different profile relationship from the taller 265/65R18 option used on other configurations. This is the size to consider when the truck has the corresponding 18-inch setup and the goal is to maintain the proper fitment category for that specific trim.
255/55R20 is a metric radial tire size with a 255-millimeter width, a 55-series profile, and a 20-inch rim diameter. On the 2025 Chevrolet Trucks Colorado, it is a trim-specific fitment tied to a 20-inch wheel package rather than the 17-inch or 18-inch setups used elsewhere in the range. The lower-profile relationship is part of what separates it from the truck's other primary sizes. It is the appropriate size to evaluate when the Colorado already has the matching 20-inch wheels and you are selecting a replacement around that existing wheel and tire combination.
285/70R17 is a metric radial size with a 285-millimeter nominal width, a 70-series profile, and fitment for a 17-inch rim. On the 2025 Chevrolet Trucks Colorado, this size is used on the ZR2 and reflects a larger off-road-oriented 17-inch tire package than the standard 17-inch fitments used on other trims. Available products in this size include BFGoodrich All-Terrain T/A KO2 choices with raised white letter sidewalls and differing load specifications. It is the size to compare when the truck is a ZR2 and the priority is staying with that specific 17-inch tire format.
315/70R17 is a metric radial tire size with a 315-millimeter nominal section width, a 70-series profile, and a 17-inch rim requirement. For the 2025 Chevrolet Trucks Colorado, this size belongs specifically to the ZR2 Bison Edition and stands apart from the other fitments in both width and overall scale. That makes trim confirmation especially important before using it as a replacement target. It is the size to investigate only when the truck is the Bison Edition or already carries the matching wheel and clearance setup that supports this larger 17-inch fitment.
Tire fitment varies across the 2025 Chevrolet Trucks Colorado lineup, and several trims use different sizes or even different wheel diameters. Checking the exact sub-model matters here, because choosing by model name alone can easily lead to the wrong tire category.

2025 Chevrolet Trucks Colorado LT
The 2025 Chevrolet Trucks Colorado LT uses a single 255/65R17 radial fitment, which keeps selection relatively straightforward once the 17-inch wheel package is confirmed. Tire choice then centers on replacing that exact size with the right construction, load specification, and use profile for how the truck is driven.
The 2025 Chevrolet Trucks Colorado Trail Boss uses more than one tire size, including both 18-inch and 20-inch wheel-based fitments. That makes wheel-diameter confirmation the first step, followed by selecting the tire that matches the truck's current setup rather than assuming every Trail Boss uses the same size.
The 2025 Chevrolet Trucks Colorado WT can use either a 17-inch or 18-inch tire package, so fitment is not limited to one universal replacement size. Matching the truck's actual wheel diameter is the practical first move before comparing available tires for daily work use or general road service.
The 2025 Chevrolet Trucks Colorado Z71 uses two different sizes depending on wheel package, with both 18-inch and 20-inch fitments appearing in the range. Tire selection starts with the wheel currently on the truck, then moves to the right size and tire style for that specific configuration.
The 2025 Chevrolet Trucks Colorado ZR2 uses 285/70R17 radial tires, giving it a distinct 17-inch fitment separate from the standard-trim packages. Once that size is confirmed, the next choice is comparing available tires by load specification, rim-width compatibility, and the type of driving the truck sees.
The 2025 Chevrolet Trucks Colorado ZR2 Bison Edition uses 315/70R17, a larger and more specialized 17-inch fitment than the rest of the lineup. Tire replacement should begin with confirming that the truck still carries the matching Bison wheel and clearance setup before moving on to any size-specific comparison.
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.

Tire Size & Fitment
What tire size fits a 2025 Chevrolet Trucks Colorado?
The 2025 Chevrolet Trucks Colorado uses several different tire sizes rather than one universal fitment. Sizes used across the lineup include 255/65R17, 265/60R18, 265/65R18, 275/65R18, 255/55R20, 275/60R20, 285/70R17, and 315/70R17, all in radial construction.
The correct choice depends on the exact sub-model and wheel diameter already on the truck. LT uses 255/65R17, ZR2 uses 285/70R17, and ZR2 Bison Edition uses 315/70R17, while WT, Trail Boss, and Z71 can vary. Checking the trim and confirming whether the truck has 17-inch, 18-inch, or 20-inch wheels should happen before comparing brands or tread styles.
What size rim does a 2025 Chevrolet Trucks Colorado use?
The 2025 Chevrolet Trucks Colorado uses 17-inch, 18-inch, and 20-inch rim diameters depending on sub-model and tire package. The 17-inch group includes sizes such as 255/65R17, 285/70R17, and 315/70R17. The 18-inch group includes 265/60R18, 265/65R18, and 275/65R18, while the 20-inch group includes 255/55R20 and 275/60R20.
Rim diameter is the first fitment check because the tire must match the wheel before anything else is evaluated. A 17-inch tire cannot be mounted on an 18-inch or 20-inch wheel, and the reverse is equally true. Looking at the sidewall marking on the current tire or confirming the truck's exact trim and wheel package will usually narrow the search quickly.
Why does the 2025 Chevrolet Trucks Colorado have more than one tire size?
The 2025 Chevrolet Trucks Colorado lineup includes several trims with different wheel packages, so tire sizing changes across the range. Some versions use 17-inch wheels, others use 18-inch or 20-inch wheels, and certain off-road-focused models use wider or taller tire packages than the standard trims.
That means tire selection is tied to configuration, not just model name. WT, Trail Boss, and Z71 can each appear with more than one size, while ZR2 and ZR2 Bison Edition use their own dedicated fitments. Matching the current wheel diameter and sub-model prevents ordering a tire that belongs to another Colorado setup with different clearance and wheel requirements.
Choosing the Right Tire
What should I consider when choosing a 285/70R17 tire for a 2025 Chevrolet Trucks Colorado?
For a 2025 Chevrolet Trucks Colorado using 285/70R17, the first checks are confirming that the truck is the ZR2 or still carries the same 17-inch wheel package, then comparing the available tire's load specification and rim-width range. BFGoodrich All-Terrain T/A KO2 options are available in this size.
Selection should also reflect how the truck is actually used. Two 285/70R17 KO2 offerings appear with different maximum load capacities and different weights, so it helps to compare those details rather than assuming every tire in the size is identical. Clearance, wheel width, and any suspension or wheel changes should be reviewed before replacing a ZR2 tire with another 285/70R17.
What sidewall styles are available for 2025 Chevrolet Trucks Colorado tires?
Among the currently covered tire options for the 2025 Chevrolet Trucks Colorado, the available sidewall style is RWL, or raised white letter. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 products offered in the supported Colorado sizes with product coverage.
Sidewall appearance matters most after the correct size and wheel diameter are settled. On a modern truck like the Colorado, raised white letters create a more traditional all-terrain look than a plain blackwall, but appearance should still come second to proper size, wheel compatibility, and the load specification that matches the truck's intended use.
What brands offer tires for the 2025 Chevrolet Trucks Colorado?
The available products for the covered 2025 Chevrolet Trucks Colorado fitments come from BFGoodrich. The size-specific offerings shown here are from the All-Terrain T/A KO2 line, including options in 255/65R17, 275/65R18, and 285/70R17.
Brand alone should not drive the choice, because the real fitment difference is still the tire size and wheel package used on the truck. After the exact trim and wheel diameter are confirmed, compare the BFGoodrich option in the correct size by its load rating, rim-width specification, and overall role on the truck rather than treating any available product as interchangeable across the lineup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2025 Chevrolet Trucks Colorado?
Yes, modifications can change tire fitment on a 2025 Chevrolet Trucks Colorado even when the tire size matches a known trim package. Aftermarket wheels, changes in wheel width or offset, suspension lifts or lowering, and body or fender modifications can all affect clearance and how the tire sits on the truck.
A Colorado that has been altered should be checked as an individual setup before replacement tires are chosen. Steering clearance, suspension travel, and room at the fenders all matter, especially on larger sizes such as 285/70R17 or 315/70R17. The safest approach is to verify the actual wheel dimensions and inspect the current running clearance before ordering another tire.
What should I inspect before driving a 2025 Chevrolet Trucks Colorado on new tires?
Before driving a 2025 Chevrolet Trucks Colorado on new tires, inspect the wheels for the correct diameter and condition, confirm that the installed tire size matches the truck's trim and wheel package, and check inflation pressure carefully. It also helps to look for rubbing at full steering lock and confirm that lug hardware is properly secured.
A short post-installation check is worthwhile after the first miles on the road. Recheck pressure, watch for uneven contact or unexpected vibration, and inspect the sidewalls and tread for any sign of interference. On a truck with larger off-road-oriented sizes, paying attention to suspension and fender clearance during turns and compression is especially important.
How often should tires on a 2025 Chevrolet Trucks Colorado be inspected?
Tires on a 2025 Chevrolet Trucks Colorado should be inspected regularly rather than only when wear becomes obvious. Pressure, tread condition, cuts, bulges, punctures, and uneven wear should be checked often, especially on a truck that sees mixed road and trail use or carries changing loads through work or recreation.
Routine inspection helps catch problems before they affect ride quality or cause avoidable tire damage. It is smart to look over the tires before longer trips, after off-road use, and any time the truck develops a pull, shake, or pressure loss. A consistent inspection habit also helps confirm that wheel alignment and suspension condition are not shortening tire life.
