The 2015 Chevrolet Trucks Colorado marked the return of Chevrolet’s midsize pickup to a market that wanted truck utility without full-size bulk. Its mix of daily drivability, light-duty work capability, and trim-level variety means tire fitment depends on how the truck was equipped. This Colorado uses modern radial sizes, with 265/70R16, 255/65R17, and 265/60R18 all appearing across the lineup on 16-, 17-, or 18-inch wheels. Available choices here lean toward BFGoodrich All-Terrain T/A KO2 products with raised white letter styling. The key is matching the exact sub-model and wheel diameter first, then choosing a tire that suits road use, appearance, and overall truck setup.
Which Tire Size Is Right for The 2015 Chevrolet Trucks Colorado
Three primary tire sizes apply to the 2015 Chevrolet Trucks Colorado, and they vary by sub-model and wheel diameter. The first step is confirming the exact trim and the actual wheel on the truck, since this Colorado uses 16-, 17-, and 18-inch rim fitments. Once that is settled, the decision becomes choosing the right radial tire within the correct size and checking that its rim-width and load characteristics suit the truck’s use.
265/70R16 is a metric radial size in which 265 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. On the 2015 Chevrolet Trucks Colorado, this size serves Base and WT applications and keeps the fitment tied to a 16-inch wheel. Available products in this size include a BFGoodrich All-Terrain T/A KO2 with raised white letter styling. It is the right size to evaluate when the truck retains its 16-inch wheel setup and a more truck-oriented all-terrain presentation is desired.
255/65R17 is a metric radial size that uses a 255-millimeter nominal section width, a 65-series profile, and a 17-inch rim diameter. For the 2015 Chevrolet Trucks Colorado, this size appears on certain LT applications and on the Z71, so it should not be treated as universal across the model line. BFGoodrich offers this size in the All-Terrain T/A KO2 series with raised white letters, giving it a more traditional light-truck sidewall look. It is the size to focus on when the truck has its original 17-inch wheel fitment or when replacing an existing 255/65R17 setup.
265/60R18 is a metric radial size with a 265-millimeter nominal section width, a 60-series profile, and an 18-inch wheel diameter. On the 2015 Chevrolet Trucks Colorado, this size is tied to certain LT configurations, making wheel confirmation especially important before ordering or comparing tires. No product choices are shown here for this size, so the fitment question matters more than sidewall or series comparison at this stage. This is the size to verify when the truck carries 18-inch wheels and you want to stay aligned with that specific Colorado setup.
Tire fitment on the 2015 Chevrolet Trucks Colorado varies by sub-model, so identifying the exact trim is the first step. Base and WT share one size, while LT can use more than one wheel and tire combination and Z71 uses its own 17-inch fitment.

2015 Chevrolet Trucks Colorado Base
The 2015 Chevrolet Trucks Colorado Base uses a 265/70R16 radial tire on a 16-inch wheel. That keeps selection centered on finding the right 16-inch replacement tire and confirming the truck still has its original wheel diameter before choosing among available options.
The 2015 Chevrolet Trucks Colorado LT can use either 255/65R17 or 265/60R18 radial tires, depending on wheel package. Tire selection starts with confirming whether the truck is on 17-inch or 18-inch wheels, since the correct size depends on that distinction.
The 2015 Chevrolet Trucks Colorado WT uses the 265/70R16 radial size, matching the 16-inch-wheel fitment used on the Base model. That makes the choice fairly straightforward so long as the truck has not been changed to a different wheel diameter.
The 2015 Chevrolet Trucks Colorado Z71 uses a 255/65R17 radial tire on a 17-inch wheel. Tire selection should stay centered on that size unless the truck has been modified, with attention paid to wheel compatibility and the kind of road or light off-road use expected.
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.
Best 2015 Chevrolet Trucks Colorado Tires for Sale
Current product choices shown for the 2015 Chevrolet Trucks Colorado center on BFGoodrich All-Terrain T/A KO2 tires in 265/70R16 and 255/65R17. These radial options use raised white letter sidewalls and differ in rim-width range, load capacity, and size-specific fitment.
These FAQs focus on the exact tire sizes used on the 2015 Chevrolet Trucks Colorado, how trim level affects fitment, and what to compare when selecting replacement radials for road use, truck stance, and wheel compatibility.
Tire Size & Fitment
What tire size fits a 2015 Chevrolet Trucks Colorado?
The 2015 Chevrolet Trucks Colorado uses three primary tire sizes: 265/70R16, 255/65R17, and 265/60R18. The correct one depends on the sub-model and wheel package, not just the model name alone. Base and WT use 265/70R16, Z71 uses 255/65R17, and LT can use either 255/65R17 or 265/60R18.
That means the first step is confirming the truck’s exact trim and actual wheel diameter before choosing a replacement tire. A Colorado that has changed wheels over time may no longer match its original setup, so checking the sidewall on the current tire and measuring the wheel diameter helps avoid ordering the wrong size.
What size rim does a 2015 Chevrolet Trucks Colorado use?
The 2015 Chevrolet Trucks Colorado uses 16-inch, 17-inch, and 18-inch rim diameters, depending on the sub-model and wheel configuration. The 265/70R16 size matches a 16-inch wheel, 255/65R17 matches a 17-inch wheel, and 265/60R18 matches an 18-inch wheel.
Rim diameter is the most important fitment check because a tire must match the wheel’s diameter exactly. Before replacing tires, confirm the wheel size on the truck rather than assuming every Colorado uses the same rim. This matters most on LT models, where more than one wheel and tire package appears.
Why does the 2015 Chevrolet Trucks Colorado have more than one tire size?
More than one tire size appears on the 2015 Chevrolet Trucks Colorado because different sub-models and wheel packages used different wheel diameters. Base and WT use 265/70R16, Z71 uses 255/65R17, and LT can use either 255/65R17 or 265/60R18 depending on configuration.
That variation means tire selection is tied to the truck’s exact trim and wheel setup rather than the model year alone. On an unmodified truck, the wheel diameter usually points to the right size immediately. On a truck with aftermarket wheels or previous changes, the current wheel and tire should be checked carefully before replacement.
Choosing the Right Tire
What should I consider when choosing a 265/70R16 tire for a 2015 Chevrolet Trucks Colorado?
For a 2015 Chevrolet Trucks Colorado using 265/70R16, start with the correct 16-inch wheel fitment and radial construction. This size appears on Base and WT models, so the main comparison points become tire type, sidewall presentation, rim-width compatibility, and load capability rather than deciding between multiple primary sizes.
A BFGoodrich All-Terrain T/A KO2 is available in this size with raised white letter styling, a 7.0 to 8.5 inch rim-width range, and a maximum load capacity of 3,195 lbs at 80 psi. That combination suits buyers who want a more aggressive truck look, but the wheel width and intended use should still be confirmed first.
What sidewall styles are available for 2015 Chevrolet Trucks Colorado tires?
The product choices shown for the 2015 Chevrolet Trucks Colorado use RWL sidewalls, meaning raised white letters. That styling appears on the available BFGoodrich All-Terrain T/A KO2 options shown in 265/70R16 and 255/65R17, giving the truck a more traditional light-truck appearance than a plain blackwall.
Sidewall treatment is mostly an appearance decision once the correct size and wheel diameter are confirmed. Raised white letters can change the truck’s visual character, especially on trims with a more off-road or all-terrain look. Buyers who want a cleaner presentation should still confirm whether the specific size they need has alternate sidewall treatments available.
What brands offer tires for the 2015 Chevrolet Trucks Colorado?
The available products shown for the 2015 Chevrolet Trucks Colorado are from BFGoodrich. The listed tire series is the All-Terrain T/A KO2, appearing in 265/70R16 and 255/65R17 with radial construction and raised white letter sidewalls.
That makes the selection process less about comparing multiple brands and more about confirming the correct size, wheel diameter, and product specifications for the truck’s setup. On Colorado trims that use 16-inch or 17-inch wheels, checking the rim-width range and load figure is especially useful before choosing a replacement all-terrain tire.
Restoration & Appearance
Which tire should I choose for a period-style 2015 Chevrolet Trucks Colorado?
A period-style choice for a 2015 Chevrolet Trucks Colorado starts with the exact size used by the truck’s trim and wheel package: 265/70R16, 255/65R17, or 265/60R18. Since this is a modern midsize pickup, keeping the correct metric radial size and wheel diameter does more for the truck’s original visual balance than forcing an alternate fitment.
For trucks using 265/70R16 or 255/65R17, the available BFGoodrich All-Terrain T/A KO2 options give a recognizable truck-oriented appearance with raised white letters. Buyers aiming for a stock-style look should compare the tire’s sidewall presentation carefully and confirm that any wheel changes over the years have not altered the original diameter.
Does correct tire fitment matter for a 2015 Chevrolet Trucks Colorado restoration?
Correct tire fitment matters on a 2015 Chevrolet Trucks Colorado because the wrong diameter or profile can change the truck’s stance, wheel-to-tire proportion, and overall appearance. Staying with the proper trim-specific size helps preserve how the truck sits visually while keeping the wheel and tire relationship in line with its intended setup.
This is especially important on LT models, where more than one wheel size appears. A truck being refreshed or restored should have its wheel diameter confirmed before replacement tires are chosen. When appearance matters, sidewall style also plays a role, since raised white letters create a more aggressive presentation than a more understated sidewall treatment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2015 Chevrolet Trucks Colorado?
Yes, modifications can affect tire fitment on a 2015 Chevrolet Trucks Colorado even when the tire size looks close to original. Aftermarket wheels, changes in wheel width, suspension lifts or lowering, and body or fender changes can all alter clearance and change which tire size works properly on the truck.
A Colorado that has been modified should have its actual wheel diameter and width checked before replacement tires are selected. Steering clearance, suspension travel, and fender room matter just as much as the size stamped on the sidewall. That is especially important on LT trims, where more than one original wheel diameter already exists.
What should I inspect before driving a 2015 Chevrolet Trucks Colorado on new tires?
Before driving a 2015 Chevrolet Trucks Colorado on new tires, inspect wheel condition, valve stems, lug hardware, and the tire’s basic installed clearance at the fenders and suspension. Tire pressure should also be set correctly, and the truck should be checked for any signs of rubbing when the steering is turned lock to lock.
It is also smart to look over alignment-related wear items such as suspension components and steering parts, since worn hardware can shorten tire life quickly. A short test drive should be followed by another visual check for contact marks or uneven seating. That extra step matters most when the truck has replacement wheels or recent suspension work.
How often should tires on a 2015 Chevrolet Trucks Colorado be inspected?
Tires on a 2015 Chevrolet Trucks Colorado should be inspected regularly, not just when tread looks low. Pressure loss, uneven wear, cuts, punctures, bulges, and sidewall damage can develop long before a tire appears worn out, and trucks that see mixed highway and light-duty use benefit from more frequent visual checks.
A practical routine is to inspect the tires during pressure checks and before longer drives, especially if the truck has been parked for a while or used on rough roads. Any Colorado running all-terrain tires should also be watched for irregular wear patterns that may point to alignment or suspension issues rather than a tire problem alone.
