The 2020 Chevrolet Trucks Colorado sits in the modern midsize pickup segment with a broad spread of work-truck, everyday-use, and off-road-oriented configurations. That matters when it comes to tires, because this Colorado does not rely on one universal fitment across the lineup. It uses several primary radial sizes, including 265/70R16, 255/65R17, 265/65R17, 265/60R18, and 255/55R20, depending on sub-model and wheel package. Product choice in the sizes covered here leans toward BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls. The key step is confirming the exact sub-model and wheel diameter before choosing a tire for appearance, road use, or light-truck capability.
Which Tire Size Is Right for The 2020 Chevrolet Trucks Colorado
Five primary tire sizes apply to the 2020 Chevrolet Trucks Colorado, and they vary by sub-model and wheel diameter. The first thing to confirm is the exact Colorado configuration and whether it rides on a 16-, 17-, 18-, or 20-inch wheel. Once that is settled, the decision shifts to choosing the right radial tire within the correct size and matching it to the truck's intended use.
265/70R16 is a metric radial size in which 265 identifies nominal section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 16 is the rim diameter in inches. On the 2020 Chevrolet Trucks Colorado, this size serves as one of the primary fitments and uses a 16-inch wheel. Available product coverage in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. This size is worth evaluating carefully if the truck has the proper 16-inch wheel and the goal is a more traditional light-truck sidewall profile.
255/55R20 is a metric radial size that combines a 255-millimeter nominal section width with a 55-series profile on a 20-inch rim. For the 2020 Chevrolet Trucks Colorado, this size belongs only to certain wheel-package and sub-model combinations rather than the full lineup. Its lower-profile format makes wheel confirmation especially important before any replacement decision. Buyers looking at this size should match the actual 20-inch wheel setup on the truck first, then compare tire choices that preserve the intended overall fitment and clearance.
255/65R17 is a metric radial size with a 255-millimeter nominal section width, a 65-series aspect ratio, and a 17-inch rim diameter. It is one of the more widely used fitments within the 2020 Chevrolet Trucks Colorado range and appears on more than one sub-model. In the available product selection, this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. It is a useful size to confirm when the truck is on 17-inch wheels and the buyer wants a radial option with light-truck, all-terrain character.
265/60R18 is a metric radial size in which 265 is the nominal section width in millimeters, 60 is the aspect ratio, and 18 indicates rim diameter. On the 2020 Chevrolet Trucks Colorado, this size applies to specific sub-model and wheel combinations rather than every version of the truck. Its profile sits between taller truck-oriented sizing and lower-profile 20-inch fitments, so wheel identification remains the first step. This size should be chosen only after verifying that the Colorado has the proper 18-inch wheel and the intended tire dimensions remain appropriate for the vehicle setup.
265/65R17 is a metric radial size using a 265-millimeter nominal section width, a 65-series aspect ratio, and a 17-inch rim diameter. Within the 2020 Chevrolet Trucks Colorado range, this size is tied to a specific sub-model rather than the broader lineup. That makes it important not to confuse it with the other 17-inch Colorado fitment, 255/65R17, because the wheel diameter matches while the tire dimensions do not. This size should be evaluated by confirming the exact trim and current wheel setup before selecting a replacement tire.
Sub-model fitment on the 2020 Chevrolet Trucks Colorado is not uniform, and several trims use different tire sizes or wheel diameters. Checking the exact trim matters before choosing a replacement, especially where 17-inch fitments overlap but do not use the same size.

2020 Chevrolet Trucks Colorado Base
The 2020 Chevrolet Trucks Colorado Base uses the 265/70R16 radial tire size. That makes wheel confirmation fairly straightforward, and the main decision becomes choosing a suitable 16-inch replacement that matches the truck's intended use and overall fitment.
The 2020 Chevrolet Trucks Colorado LT can use 255/55R20, 255/65R17, or 265/60R18, so tire choice depends on the wheel package actually on the truck. Identifying the rim diameter first prevents ordering the right-looking tire in the wrong size range.
The 2020 Chevrolet Trucks Colorado WT uses more than one radial fitment, including 255/65R17, 265/60R18, and 265/70R16. Replacement selection starts with confirming the current wheel diameter, then choosing a tire that suits work use, general driving, or a more truck-oriented appearance.
The 2020 Chevrolet Trucks Colorado Z71 uses the 255/65R17 radial size. Tire selection is simpler once the 17-inch wheel setup is confirmed, and buyers can focus on tread character, sidewall presentation, and compatibility with the truck's present configuration.
The 2020 Chevrolet Trucks Colorado ZR2 uses the 265/65R17 radial size. Because another 17-inch size also appears elsewhere in the Colorado range, it is important to verify the exact trim and tire code rather than relying on rim diameter alone.
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.

Colorado tire questions usually come down to the exact trim, wheel diameter, and whether the truck uses 16-, 17-, 18-, or 20-inch fitment. The FAQs below focus on size identification, rim fitment, product selection, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2020 Chevrolet Trucks Colorado?
The 2020 Chevrolet Trucks Colorado uses five primary radial tire sizes: 265/70R16, 255/55R20, 255/65R17, 265/60R18, and 265/65R17. The correct one depends on the truck's sub-model and wheel package, so there is not one universal tire size for every Colorado in this model year.
The practical first step is checking the exact trim and the tire code already mounted on the truck. A Colorado may use 16-, 17-, 18-, or 20-inch wheels, and two different 17-inch tire sizes appear in the lineup, so rim diameter alone is not always enough to identify the proper replacement.
What size rim does a 2020 Chevrolet Trucks Colorado use?
A 2020 Chevrolet Trucks Colorado may use 16-inch, 17-inch, 18-inch, or 20-inch rims, depending on sub-model and factory wheel setup. The tire sizes tied to those diameters are 265/70R16, 255/65R17, 265/65R17, 265/60R18, and 255/55R20.
Rim diameter should be confirmed before any tire purchase because the Colorado lineup spans several wheel sizes. It also helps to verify the wheel width and the exact size stamped on the current tires, especially on trucks that may have had replacement wheels installed after the original setup left the factory.
Do all 2020 Chevrolet Trucks Colorado sub-models use the same tire size?
No, the 2020 Chevrolet Trucks Colorado does not use the same tire size across all sub-models. The Base uses 265/70R16, the Z71 uses 255/65R17, the ZR2 uses 265/65R17, and the LT and WT can appear with multiple tire sizes depending on wheel configuration.
That variation means trim identification matters before comparing tire options. It is especially important on LT and WT trucks, where more than one primary size is used, and on 17-inch applications, where both 255/65R17 and 265/65R17 appear but serve different Colorado configurations.
Choosing the Right Tire
What should I consider when choosing a tire for a 2020 Chevrolet Trucks Colorado?
Start with the exact tire size and wheel diameter used on the truck, since the 2020 Chevrolet Trucks Colorado spans five primary radial fitments. After size is confirmed, compare construction, intended use, load capacity, and whether the tire's overall character matches how the truck is driven.
A work-oriented Colorado, a daily-driven truck, and a more rugged setup may not call for the same tire style even when the size is correct. Rim-width compatibility, present suspension height, and any aftermarket wheel changes should be checked so the chosen tire suits the vehicle rather than only matching the sidewall code.
What sidewall styles are available for 2020 Chevrolet Trucks Colorado tires?
Among the currently covered products for the 2020 Chevrolet Trucks Colorado, the visible sidewall style is RWL, or raised white letter. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options shown for supported Colorado sizes.
Sidewall style affects appearance as much as size affects fitment, so it is worth deciding whether a more aggressive truck presentation suits the Colorado's look and use. The right choice still begins with the correct tire size, since the preferred sidewall treatment only matters after wheel diameter and fitment are properly matched.
What brands offer tires for the 2020 Chevrolet Trucks Colorado?
The currently covered tire options for this 2020 Chevrolet Trucks Colorado are from BFGoodrich. In the sizes shown here, the available products appear in the All-Terrain T/A KO2 series for selected Colorado fitments.
Brand is only one part of the decision, because the correct size still depends on the truck's trim and wheel package. Once the fitment is confirmed, comparing the tire's sidewall style, rim-width range, and load capacity helps determine whether that specific option suits the Colorado's intended use.
Restoration & Appearance
Does correct tire fitment matter for the appearance of a 2020 Chevrolet Trucks Colorado?
Yes, correct tire fitment has a major effect on how a 2020 Chevrolet Trucks Colorado looks. The truck uses several different tire sizes and wheel diameters across the lineup, so choosing the wrong size can change the visual balance between sidewall height, wheel proportion, and overall stance.
Appearance decisions should begin with the proper factory-type size range for the specific trim, then move to sidewall treatment and tread character. Raised white letter all-terrain styling is available in some covered sizes, but it still needs to be matched to the truck's actual wheel setup rather than chosen on looks alone.
Which tire should I choose for a period-style 2020 Chevrolet Trucks Colorado?
A period-style approach on a 2020 Chevrolet Trucks Colorado starts with keeping the correct original-size format for the specific sub-model and wheel diameter. Since this truck is a modern application with radial fitments throughout, the right visual direction usually comes from staying with the proper size and selecting a sidewall and tread style that suits the truck's character.
For a more rugged contemporary truck look, an all-terrain radial with raised white lettering may be appealing where available. Buyers focused on exact as-delivered appearance should compare the truck's present wheel and tire setup with window-sticker, dealer, or model-specific Chevrolet references before making an appearance-driven change.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Chevrolet Trucks Colorado?
Yes, modifications can affect tire fitment on a 2020 Chevrolet Trucks Colorado even when the tire size looks close to stock. Aftermarket wheels, changes in wheel width or offset, suspension lifts, leveling kits, lowering, or body alterations can all influence clearance and how the tire sits within the wheel opening.
That matters even more on a Colorado with multiple factory wheel diameters and more than one 17-inch tire size in circulation. A modified truck should have the actual wheel dimensions and available steering, fender, and suspension clearance checked before replacing tires, rather than relying only on the model year and trim badge.
What should I inspect before driving a 2020 Chevrolet Trucks Colorado on new tires?
Before driving a 2020 Chevrolet Trucks Colorado on new tires, inspect the wheel condition, valve stems, lug hardware, and the tire's mounted size against the truck's actual fitment. It is also wise to confirm cold inflation pressure, look for any interference at full steering lock, and make sure all four tires match the intended setup.
A short test drive should be followed by another look for rubbing, air loss, or uneven seating, especially if the truck has replacement wheels. Trucks that see rough roads or trail use also benefit from checking alignment and suspension condition so the new tires wear evenly and perform as expected.
How often should tires on a 2020 Chevrolet Trucks Colorado be inspected?
Tires on a 2020 Chevrolet Trucks Colorado should be inspected regularly, not only when tread looks low. Routine checks should include inflation pressure, visible cuts, sidewall damage, punctures, uneven wear, and any signs that one corner of the truck is carrying or wearing a tire differently than the others.
More frequent inspection is smart if the Colorado is used for hauling, rough-road driving, or long highway trips. It also helps to recheck tires after impacts, alignment changes, or wheel service, since a truck with multiple possible rim sizes and fitments can develop issues that are easier to catch early than after a failure.
