The 2012 Chevrolet Trucks Silverado 1500 LT sits in the heart of the modern full-size pickup market, blending everyday usability with the broad wheel and suspension variations that make half-ton tire fitment worth checking carefully. Buyers often approach this truck with a mix of work, towing, weekend, and appearance goals, so tire choice is more than a simple replacement exercise. This Silverado 1500 LT uses radial tire fitments, with 245/70R17, 265/70R17, 265/65R18, and 275/55R20 all appearing across different configurations. That makes wheel diameter and sub-model identification especially important before comparing the available all-terrain options. The right choice starts with matching the truck's exact setup, then confirming rim compatibility and intended road use.
Which Tire Size Is Right for The 2012 Chevrolet Trucks Silverado 1500 LT
The 2012 Chevrolet Trucks Silverado 1500 LT uses four primary tire sizes, and the right one depends on the truck's exact sub-model and wheel package. These fitments are all radial, but they span 17-inch, 18-inch, and 20-inch rims, so confirming wheel diameter is the first step. Once that is settled, the real comparison becomes load specification, rim-width compatibility, and whether the truck's use calls for one of the available all-terrain choices.
275/55R20 is a metric radial size that uses a 275-millimeter nominal section width, a 55-series profile, and a 20-inch rim. On the 2012 Chevrolet Trucks Silverado 1500 LT, this size is tied to the 20 Inch Option configuration, making wheel confirmation especially important before any tire selection begins. Its lower-profile metric format gives it a different fitment role than the 17-inch and 18-inch sizes used elsewhere in the LT lineup. Choose this size only when the truck is actually equipped for the 20-inch setup, then compare the tire against the wheel and overall vehicle clearance requirements.
245/70R17 is a metric radial size with a 245-millimeter nominal section width, a 70-series aspect ratio, and a 17-inch rim diameter. This fitment appears on certain 2012 Chevrolet Trucks Silverado 1500 LT 4x2 and 4x4 configurations, so it is one of the key sizes to verify when the truck remains on a 17-inch wheel. The available product in this size uses BFGoodrich's All-Terrain T/A KO2 series with raised white letter sidewalls, giving it a distinctly truck-oriented look. It is a useful choice to evaluate when the priority is staying with the narrower 17-inch LT fitment while matching the wheel's required dimensions.
265/70R17 is a metric radial size that combines a 265-millimeter nominal section width with a 70-series profile on a 17-inch rim. It is one of the most broadly used fitments within the 2012 Chevrolet Trucks Silverado 1500 LT range, appearing across 4x2, 4x4, extended-cab long-box, and some Z71 applications. Product choices in this size include BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls and different load capacities. This size deserves a close look when the truck has 17-inch wheels and the owner wants to compare the practical differences between available specifications within the same overall tire format.
265/65R18 is a metric radial size that uses a 265-millimeter nominal section width, a 65-series profile, and an 18-inch rim. On the 2012 Chevrolet Trucks Silverado 1500 LT, it appears with the Z71 sub-model, which makes it a configuration-specific fitment rather than a universal LT size. Its role sits between the 17-inch and 20-inch fitments, so the most important step is confirming that the truck actually carries the 18-inch wheel package. This is the size to evaluate when matching an LT Z71 setup and keeping the tire choice aligned with the truck's original wheel diameter.
2012 Chevrolet Trucks Silverado 1500 LT Sub-Model Tires
Tire fitment for the 2012 Chevrolet Trucks Silverado 1500 LT is not the same across every covered sub-model. Some configurations share 17-inch sizes, while others move to 18-inch or 20-inch fitments, so checking the exact sub-model and wheel package matters before comparing tires.

2012 Chevrolet Trucks Silverado 1500 LT (20 Inch Option)
This 20 Inch Option configuration uses the 275/55R20 radial size, separating it clearly from the 17-inch and 18-inch LT fitments. Tire selection starts with confirming that the truck still has its 20-inch wheel setup, then comparing options that suit that rim diameter and intended use.
The 4x2 version can use either 245/70R17 or 265/70R17 radial tires, so this is not a one-size-fits-all sub-model. The practical next step is confirming which 17-inch wheel and tire package is actually on the truck before choosing between the available all-terrain specifications.
The 4x4 configuration also appears with either 245/70R17 or 265/70R17 radial tires on 17-inch rims. That makes wheel and current tire verification important, especially if the truck has seen service replacements or aftermarket changes over time.
2012 Chevrolet Trucks Silverado 1500 LT 4x4 Ext. Cab Long Box
This extended-cab long-box 4x4 setup uses the 265/70R17 radial size, making its fitment more straightforward than the broader 4x2 and 4x4 groupings. Tire selection can focus less on size uncertainty and more on matching the truck's 17-inch wheel dimensions and use case.
The Z71 sub-model uses either 265/65R18 or 265/70R17 radial tires, so identifying the actual wheel package is essential before moving further. Once the wheel diameter is confirmed, the buyer can focus on selecting the correct tire format rather than assuming every Z71 uses the same size.
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 2012 Chevrolet Trucks Silverado 1500 LT?
The 2012 Chevrolet Trucks Silverado 1500 LT uses four primary tire sizes across its covered configurations: 245/70R17, 265/70R17, 265/65R18, and 275/55R20. All of these are radial sizes, and they do not apply universally across every LT sub-model. Some 4x2 and 4x4 trucks use 17-inch fitments, the Z71 can use either a 17-inch or 18-inch size, and the 20 Inch Option uses a 20-inch tire.
The most important step is matching the tire size to the truck's actual wheel diameter and sub-model setup. A Silverado that has had replacement wheels or previous tire changes can easily wear a size different from another LT parked next to it. Check the current wheel size, the truck's exact configuration, and the placard or existing fitment before choosing a replacement.
What size rim does a 2012 Chevrolet Trucks Silverado 1500 LT use?
The 2012 Chevrolet Trucks Silverado 1500 LT appears with 17-inch, 18-inch, and 20-inch rim diameters depending on configuration. The 245/70R17 and 265/70R17 sizes use 17-inch rims, the 265/65R18 size uses an 18-inch rim, and the 275/55R20 size uses a 20-inch rim. That spread is why the LT cannot be treated as a single wheel-size truck when replacing tires.
Start by verifying the actual wheel diameter on the truck rather than assuming it from the trim badge alone. The Z71 and 20 Inch Option especially make wheel-package confirmation important, and aftermarket wheel changes can add even more variation. Once rim diameter is confirmed, compare tire size, rim-width compatibility, and clearance instead of selecting by appearance alone.
Why does the 2012 Chevrolet Trucks Silverado 1500 LT have more than one tire size?
More than one tire size appears on the 2012 Chevrolet Trucks Silverado 1500 LT because the LT range includes different sub-models and wheel packages. A 4x2 or 4x4 truck may use 245/70R17 or 265/70R17, the Z71 can use 265/65R18 or 265/70R17, and the 20 Inch Option uses 275/55R20. Those differences reflect configuration changes rather than interchangeable sizing across the entire model line.
That means the correct tire is determined by the truck's exact setup, not simply by the year and trim name. Tire size affects wheel compatibility and vehicle clearance, so the first question is always which wheels are on the truck now. A careful check prevents choosing a tire that matches another Silverado LT but not the one sitting in the driveway.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2012 Chevrolet Trucks Silverado 1500 LT?
For a 2012 Chevrolet Trucks Silverado 1500 LT that uses 265/70R17, start with the basics: correct size, radial construction, and a 17-inch wheel. In the available choices, BFGoodrich All-Terrain T/A KO2 tires appear in more than one specification, including different load capacities and weights. That makes 265/70R17 selection more about matching the truck's use and wheel requirements than simply picking any tire with the same size code.
Rim-width compatibility matters here, since the available 265/70R17 products are intended for 7.0- to 9.0-inch rims. Compare the truck's wheel width, whether it sees heavier-duty use, and whether the owner wants an all-terrain tire with a raised white letter presentation. Staying inside the right size is only the beginning; the finer product details help narrow the best match for the truck's actual role.
What sidewall styles are available for 2012 Chevrolet Trucks Silverado 1500 LT tires?
Among the available products for this 2012 Chevrolet Trucks Silverado 1500 LT fitment set, the visible sidewall style is RWL, or raised white letter. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options offered in the covered 17-inch sizes. It gives the truck a more traditional light-truck appearance than a plain blackwall sidewall, while still staying within a modern radial all-terrain format.
Sidewall style should be chosen after the correct tire size and wheel diameter are confirmed. Appearance matters, but it does not override the need to match the truck's actual 17-inch setup, load needs, and rim-width range. For some owners, raised white letters are part of the truck look; for others, the more important comparison is the tire's specification within that same sidewall style.
What brands offer tires for the 2012 Chevrolet Trucks Silverado 1500 LT?
The available products for the covered 2012 Chevrolet Trucks Silverado 1500 LT tire sizes come from BFGoodrich. The product line shown for these fitments is the All-Terrain T/A KO2 series, appearing in 245/70R17 and 265/70R17 with raised white letter sidewalls. Since the assortment is centered on one brand and one series, the key differences are found in size, load specification, and wheel-width compatibility rather than brand-to-brand comparison.
That simplifies the buying process, but it also means size verification becomes even more important. A 245/70R17 truck and a 265/70R17 truck may both use a BFGoodrich KO2, yet the correct choice still depends on the wheel package and intended use. Check the truck's exact fitment first, then compare the available specifications within the matching size.
Restoration & Appearance
Which tire should I choose for a period-style 2012 Chevrolet Trucks Silverado 1500 LT?
A period-style approach on a 2012 Chevrolet Trucks Silverado 1500 LT starts with using the tire size that matches the truck's actual sub-model and wheel package. Since this is a modern truck with multiple factory-era fitment paths, the right visual starting point could be 245/70R17, 265/70R17, 265/65R18, or 275/55R20 depending on configuration. Choosing the correct diameter and profile matters more than forcing a size that belongs to another LT setup.
Appearance should then be balanced against how the truck will be driven. The available 17-inch all-terrain options with raised white letters create a familiar truck-sidewall presentation, but visual preference should still follow proper fitment and wheel compatibility. When exact as-delivered authenticity matters, check build records, original sales literature, or marque-specific references tied to the truck's actual configuration.
How does tire construction affect the appearance of a restored 2012 Chevrolet Trucks Silverado 1500 LT?
For the 2012 Chevrolet Trucks Silverado 1500 LT, tire construction is straightforward because the primary fitments are radial. That means the visual character comes less from choosing between bias-ply and radial construction and more from selecting the correct modern metric size, wheel diameter, and sidewall style. On a truck from this era, proportion and stance are shaped mainly by the proper 17-inch, 18-inch, or 20-inch fitment rather than vintage-style construction changes.
A restored or well-kept Silverado can still look noticeably off if the tire profile or wheel diameter does not match the truck's intended setup. Even within radial fitments, moving to the wrong size can alter the truck's visual balance. Keep the truck's actual configuration in mind first, then use sidewall treatment and tread style to fine-tune appearance without stepping outside the proper fitment range.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2012 Chevrolet Trucks Silverado 1500 LT?
Yes, modifications can affect tire fitment on a 2012 Chevrolet Trucks Silverado 1500 LT. Wheel changes, suspension lifts or lowering, altered offsets, and body or fender modifications can all change how a tire sits in the wheel opening. That matters even more on this truck because the LT already appears with multiple stock tire and wheel combinations, so there is no single baseline fitment that applies to every example.
Any truck with aftermarket wheels or suspension changes should be checked carefully for rim diameter, wheel width, steering clearance, and full-travel clearance before a replacement tire is chosen. A size that works on one Silverado LT may not suit another with different hardware. Looking at the current setup first helps avoid rubbing, mismatch, or unnecessary compromises in handling and load support.
What should I inspect before driving a 2012 Chevrolet Trucks Silverado 1500 LT on new tires?
Before driving a 2012 Chevrolet Trucks Silverado 1500 LT on new tires, inspect the wheels for the correct diameter and condition, confirm the tire size matches the truck's configuration, and verify inflation is set appropriately for the installed tire. It also makes sense to look over the suspension, steering components, and brakes, since worn front-end parts can affect how a fresh set of tires performs on the road.
A short follow-up check after the first miles is just as important. Watch for any rubbing at full steering lock, uneven stance, vibration, or early signs of irregular wear. Lug torque, air retention, and clearance should all be rechecked once the tires have settled in. Those simple inspections help confirm that the new tires suit both the truck and its actual wheel setup.
How often should tires on a 2012 Chevrolet Trucks Silverado 1500 LT be inspected?
Tires on a 2012 Chevrolet Trucks Silverado 1500 LT should be inspected regularly, not only when tread looks worn. A good routine includes checking air pressure and visible condition monthly, then giving the tires a closer inspection before longer trips, towing, or heavier seasonal use. On a truck with multiple possible wheel packages, it is also smart to confirm that all four tires still match in size and construction.
Look for cracking, cuts, bulges, punctures, uneven wear, and signs of slow air loss during those inspections. Trucks that sit for longer periods still deserve routine checks because age, storage conditions, and underinflation can affect tire condition even without high mileage. Catching problems early helps protect ride quality, steering feel, and overall road readiness before a small issue becomes a larger one.
