The 2012 Chevrolet Trucks Silverado 1500 LTZ sits in the full-size pickup market as a well-equipped version of a truck known for daily usability, towing duty, and light off-road versatility. For tire selection, that matters because this LTZ configuration spans several modern radial sizes depending on wheel package and sub-model, including 17-inch, 18-inch, and 20-inch setups. The real first step is confirming whether the truck is a 4x2, 4x4, Z71, or 20 Inch Option configuration before choosing a tire. Available product choices in the covered sizes lean toward BFGoodrich All-Terrain T/A KO2 options with raised white letter styling, so appearance, load rating, and intended use all deserve a closer look.
Which Tire Size Is Right for The 2012 Chevrolet Trucks Silverado 1500 LTZ
Four primary tire sizes apply to the 2012 Chevrolet Trucks Silverado 1500 LTZ, and they vary by sub-model and wheel package. The first thing to confirm is wheel diameter, since this truck appears with 17-inch, 18-inch, and 20-inch rims, and then match that to the exact LTZ configuration such as 4x2, 4x4, Z71, or the 20 Inch Option.
275/55R20 is a modern metric radial size in which 275 is the nominal section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 20 is the wheel diameter in inches. On the 2012 Chevrolet Trucks Silverado 1500 LTZ, this size belongs to the 20 Inch Option and gives the buyer a wheel-package-specific fitment to match before looking at tire style or tread character. Its lower-profile metric format sets it apart from the 17-inch and 18-inch LTZ sizes. Choosing this size starts with confirming the truck actually has the 20-inch wheel setup now, especially if wheels have been changed over time.
245/70R17 is a metric radial size with a 245-millimeter nominal section width, a 70-series profile, and a 17-inch rim diameter. For the 2012 Chevrolet Trucks Silverado 1500 LTZ, it appears on certain 4x2 and 4x4 configurations, so it is not the universal LTZ fitment across every version of the truck. Product selection in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewall styling and an E-load construction. It is a size to evaluate carefully when the truck still uses a 17-inch wheel and the intended use includes work, road driving, or all-terrain service.
265/70R17 is another metric radial size, using a wider 265-millimeter nominal section width with a 70-series profile on a 17-inch rim. This is the broadest-reaching 17-inch fitment in the 2012 Chevrolet Trucks Silverado 1500 LTZ range, appearing on 4x2, 4x4, 4x4 Ext. Cab Long Box, and some Z71 applications. Available choices include BFGoodrich All-Terrain T/A KO2 tires in raised white letter form, with more than one load-capacity specification in the same base size. That makes this size less about basic fitment alone and more about matching the truck's actual wheel setup and duty cycle.
265/65R18 is a metric radial tire size that pairs a 265-millimeter nominal section width with a 65-series aspect ratio on an 18-inch wheel. On the 2012 Chevrolet Trucks Silverado 1500 LTZ, this size is tied to the Z71 configuration, making sub-model confirmation important before moving ahead. Its 18-inch wheel requirement separates it clearly from the 17-inch LTZ fitments and the 20-inch option package. This size is worth evaluating when the truck retains its 18-inch setup and the goal is to keep tire dimensions aligned with the Z71 wheel package rather than switching to a different diameter.
2012 Chevrolet Trucks Silverado 1500 LTZ Sub-Model Tires
Tire fitment on the 2012 Chevrolet Trucks Silverado 1500 LTZ is not one-size-fits-all, because wheel diameter and tire size change across several LTZ sub-models. Checking the exact configuration matters before selecting a tire, especially where 17-inch, 18-inch, and 20-inch setups overlap within the same model line.

2012 Chevrolet Trucks Silverado 1500 LTZ (20 Inch Option)
The 20 Inch Option uses a 275/55R20 radial, which makes wheel-diameter confirmation the key first step before comparing any tire. This configuration is best approached by verifying that the truck still wears its 20-inch setup and has not been changed to a 17-inch or 18-inch wheel package.
The LTZ 4x2 can use either 245/70R17 or 265/70R17 radials, so the exact tire choice depends on the wheel and tire combination already on the truck. That means a buyer should confirm the existing 17-inch setup before comparing load capacity, sidewall presentation, or intended road and all-terrain use.
The LTZ 4x4 also appears with both 245/70R17 and 265/70R17 radial fitments, making this a wheel-and-size verification exercise rather than a simple trim-level assumption. Tire selection comes down to matching the mounted size first, then evaluating the load specification and overall use of the truck.
2012 Chevrolet Trucks Silverado 1500 LTZ 4x4 Ext. Cab Long Box
The LTZ 4x4 Ext. Cab Long Box uses 265/70R17, which simplifies size selection compared with other LTZ sub-models that carry more than one 17-inch possibility. The practical decision here is choosing the right version of that size for the truck's working load, wheel width, and intended on-road or mixed-use driving.
The LTZ Z71 can use either 265/65R18 or 265/70R17 radials, so identifying the truck's actual wheel package is essential before narrowing down tires. Once the wheel diameter is confirmed, the decision shifts toward keeping the current setup consistent and choosing a tire that suits how the truck is driven.
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.

These Silverado 1500 LTZ tire questions focus on size by sub-model, wheel diameter, radial fitment, available BFGoodrich choices, and the checks that matter before putting a collector-kept or working truck back on the road.
Tire Size & Fitment
What tire size fits a 2012 Chevrolet Trucks Silverado 1500 LTZ?
The 2012 Chevrolet Trucks Silverado 1500 LTZ uses four primary radial tire sizes: 275/55R20, 245/70R17, 265/70R17, and 265/65R18. The correct one depends on the truck's exact LTZ sub-model and wheel package, so there is not a single universal size for every version.
The safest way to narrow it down is to confirm the truck's current wheel diameter first, then match the size to the exact configuration such as 4x2, 4x4, Z71, or 20 Inch Option. If the truck has changed wheels over time, check the wheel itself and the existing tire sidewall before choosing a replacement.
What size rim does a 2012 Chevrolet Trucks Silverado 1500 LTZ use?
A 2012 Chevrolet Trucks Silverado 1500 LTZ can use 17-inch, 18-inch, or 20-inch rims, depending on the sub-model and wheel option. The associated tire sizes are 245/70R17 or 265/70R17 on 17-inch wheels, 265/65R18 on 18-inch wheels, and 275/55R20 on 20-inch wheels.
That means rim diameter has to be confirmed before tire shopping begins. A 17-inch tire will not mount on an 18-inch or 20-inch wheel, and the same issue applies in reverse. Looking at the sidewall size on the current tire and physically verifying the wheel setup is especially important on trucks that may have had wheel upgrades.
Why does the 2012 Chevrolet Trucks Silverado 1500 LTZ have more than one tire size?
This LTZ uses more than one tire size because the model line includes different wheel packages and sub-model configurations. A 20 Inch Option uses 275/55R20, the Z71 can use 265/65R18 or 265/70R17, and several 4x2 and 4x4 versions appear with either 245/70R17 or 265/70R17.
The practical takeaway is that trim name alone is not enough to choose a tire. Two Silverado 1500 LTZ trucks from the same year can need different sizes based on drivetrain, package, or wheels currently installed. Matching the actual sub-model and wheel diameter prevents buying a tire that is correct for another LTZ but not for yours.
Choosing the Right Tire
What should I consider when choosing a tire for a 2012 Chevrolet Trucks Silverado 1500 LTZ?
Start with the exact tire size and wheel diameter that belong on the truck's specific LTZ configuration. From there, compare radial construction details such as load capacity, rim-width range, and whether the truck's use is closer to daily road driving, truck duty, or mixed on-road and all-terrain service.
A Silverado that sees cargo, towing, rough roads, or trail use may need a different load specification than one driven mostly on pavement. It also helps to check whether the truck still carries its original wheel diameter or has been changed. Choosing by appearance alone can overlook load and wheel-compatibility details that matter on a pickup.
What sidewall styles are available for 2012 Chevrolet Trucks Silverado 1500 LTZ tires?
The available products in the covered 17-inch LTZ sizes use RWL sidewalls, meaning raised white letters. That gives the truck a more traditional all-terrain look than a plain blackwall and pairs naturally with the BFGoodrich All-Terrain T/A KO2 series offered in those sizes.
Sidewall style is an appearance choice, but it should still come after confirming the correct size and wheel fitment. On a Silverado 1500 LTZ, raised white letters can suit a sport-truck or off-road-inspired presentation, while the more important technical checks remain the tire's exact dimensions, load specification, and wheel-width compatibility.
What brands offer tires for the 2012 Chevrolet Trucks Silverado 1500 LTZ?
The available products for the covered Silverado 1500 LTZ fitments come from BFGoodrich. In the 17-inch sizes shown here, the brand appears through the All-Terrain T/A KO2 line, which keeps the product comparison focused on exact size, load specification, and wheel-width compatibility rather than cross-brand differences.
That kind of product range is useful when the goal is choosing the right version of a known tire family rather than sorting through many brands at once. Once the truck's correct size is confirmed, compare the available BFGoodrich options by how the truck is used, the wheel width it carries, and the load demands placed on it.
Restoration & Appearance
Which tire should I choose for a period-style 2012 Chevrolet Trucks Silverado 1500 LTZ?
A period-style choice for a 2012 Chevrolet Trucks Silverado 1500 LTZ starts with retaining the truck's correct wheel diameter and matching tire size for its exact configuration. On the covered product side, the available 17-inch options center on BFGoodrich All-Terrain T/A KO2 radials, which suit a traditional truck and SUV presentation.
Appearance should follow fitment, not replace it. A 4x2, 4x4, Z71, and 20 Inch Option do not all share the same setup, so confirming the truck's actual wheels matters before chasing a certain look. For a more exact restoration-minded result, compare the current setup with period photos, original sales material, or marque-specific references.
How does tire construction affect the appearance of a restored 2012 Chevrolet Trucks Silverado 1500 LTZ?
On this Silverado 1500 LTZ, the primary fitments are radial tires, so the truck's intended appearance is already tied to a modern radial profile rather than an older bias-ply look. Construction affects how the sidewall, tread presence, and overall stance read visually, especially on 17-inch, 18-inch, and 20-inch wheel packages.
Even within radial construction, appearance can shift with sidewall styling and the tire series selected. Raised white letters create a more assertive truck look than a plain sidewall would, while size changes across wheel packages also influence the visual balance. Keeping the correct wheel diameter for the truck's configuration helps preserve a more coherent finished appearance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Chevrolet Trucks Silverado 1500 LTZ?
Yes. Wheel changes, suspension lifts or lowering, offset differences, and body or fender alterations can all affect tire fitment on a 2012 Chevrolet Trucks Silverado 1500 LTZ. That matters even more on this truck because LTZ fitment already spans 17-inch, 18-inch, and 20-inch wheel diameters across different configurations.
A truck that has aftermarket wheels may no longer match the original LTZ package it left with, so the current setup should be inspected before any replacement tire is chosen. Check wheel diameter and width, look for steering and fender clearance at full lock, and confirm that the tire's load specification still matches how the truck is used.
What should I inspect before driving a 2012 Chevrolet Trucks Silverado 1500 LTZ on new tires?
Before road use, inspect the wheels for damage, confirm lug hardware is correct, and make sure the tires match the truck's actual size and wheel diameter. It also helps to check inflation pressure, tread seating, and overall clearance around the suspension, fenders, and steering components once the new tires are mounted.
A Silverado that has sat for long periods or changed wheel packages deserves extra attention. Look over brake hoses, shocks, and steering parts for wear, and recheck pressure after the first few drives to catch any slow air loss. On a pickup, it is also smart to think about the loads the truck will carry before heading out.
How often should tires on a 2012 Chevrolet Trucks Silverado 1500 LTZ be inspected?
Tires on a 2012 Chevrolet Trucks Silverado 1500 LTZ should be inspected regularly, not just at replacement time. Frequent visual checks for cracking, cuts, bulges, uneven wear, and air loss are especially worthwhile on a truck that sees mixed duty, sits for stretches, or carries changing loads through the year.
A practical habit is to inspect them before longer drives and anytime the truck's handling, ride, or steering feel changes. Pressure should be checked on a routine schedule as well, since underinflation or overinflation can affect wear and load behavior. If the Silverado has been modified or used off pavement, add wheel and sidewall inspections more often.
