The 2013 Chevrolet Trucks Silverado 1500 LTZ sits in the final years of the GMT900 generation, a period when half-ton pickups blended everyday comfort with serious utility and a more upscale trim presentation. LTZ models often vary by wheel package and drivetrain, so tire selection starts with confirming the exact setup on the truck. This Silverado 1500 LTZ uses radial tire fitments in 17-inch, 18-inch, and 20-inch sizes, depending on sub-model and wheel option. That makes the real decision less about vintage construction choices and more about matching the correct size, wheel diameter, and intended use. Owners balancing appearance, load needs, and road or light off-road duty should verify the truck's actual wheels before selecting tires.
Which Tire Size Is Right for The 2013 Chevrolet Trucks Silverado 1500 LTZ
Four primary tire sizes apply to the 2013 Chevrolet Trucks Silverado 1500 LTZ, and they do not all fit the same truck configuration. Sizes vary by sub-model and wheel package, with 17-inch, 18-inch, and 20-inch rim diameters represented. The first step is confirming the exact LTZ configuration and wheel diameter on the truck, since that determines which radial size belongs on it before comparing tire style, load capacity, or intended use.
A 275/55R20 tire uses a 275-millimeter nominal section width, a 55-series aspect ratio, radial construction, and a 20-inch rim. On the 2013 Chevrolet Trucks Silverado 1500 LTZ, this size belongs to the 20 Inch Option configuration, so it is tied closely to that wheel package rather than the full LTZ range. This modern metric radial format is familiar to current truck owners and centers the fitment decision on wheel diameter first. It is the right size to evaluate when the truck already wears 20-inch wheels and the goal is to stay with the proper LTZ wheel-and-tire proportion.
A 245/70R17 tire is a metric radial with a 245-millimeter nominal section width, a 70-series profile, and fitment for a 17-inch rim. On the 2013 Chevrolet Trucks Silverado 1500 LTZ, this size appears on certain 4x2 and 4x4 configurations, so it should not be assumed across every LTZ sub-model. Available product coverage in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewall styling. This is the size to review when the truck uses 17-inch wheels and a slightly narrower fitment than the 265-section alternatives.
A 265/70R17 tire combines a 265-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 17-inch rim. It is one of the more broadly used LTZ fitments here, appearing across 4x2, 4x4, 4x4 Ext. Cab Long Box, and some Z71 applications, but it still depends on the truck's exact configuration. Product choices in this size include BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls and different load-capacity specifications. This size deserves a closer look when the truck has 17-inch wheels and the owner wants to compare utility-oriented tire specs within the correct fitment.
A 265/65R18 tire uses a 265-millimeter nominal section width, a 65-series profile, radial construction, and an 18-inch rim. For the 2013 Chevrolet Trucks Silverado 1500 LTZ, this size is associated with the Z71 sub-model, making wheel diameter and package identification especially important before purchase. This metric radial format sits between the 17-inch and 20-inch LTZ fitments and reflects a different wheel-and-tire package rather than a casual substitute. It is the size to consider when the truck is a Z71 with 18-inch wheels and the goal is to stay aligned with that setup.
2013 Chevrolet Trucks Silverado 1500 LTZ Sub-Model Tires
Tire fitment for the 2013 Chevrolet Trucks Silverado 1500 LTZ varies by sub-model and wheel package rather than staying uniform across the entire LTZ range. Checking the exact drivetrain, package, and wheel diameter matters first, because 17-inch, 18-inch, and 20-inch fitments are all represented here.

2013 Chevrolet Trucks Silverado 1500 LTZ (20 Inch Option)
The 20 Inch Option uses a dedicated 275/55R20 radial fitment, which sets it apart from the 17-inch and 18-inch LTZ configurations. Tire selection here begins with confirming that the truck is actually on the 20-inch wheel package before comparing any replacement choices.
The LTZ 4x2 uses 17-inch radial tire fitments and may appear with either 245/70R17 or 265/70R17 depending on the truck's setup. That makes wheel and existing tire verification important before choosing between narrower and wider 17-inch replacement options.
The LTZ 4x4 also uses 17-inch radial fitments, with both 245/70R17 and 265/70R17 associated with this sub-model. Owners should confirm the current wheel-and-tire combination on the truck rather than assuming every 4x4 LTZ uses the same 17-inch size.
2013 Chevrolet Trucks Silverado 1500 LTZ 4x4 Ext. Cab Long Box
The LTZ 4x4 Ext. Cab Long Box is tied specifically to the 265/70R17 radial size within this fitment group. That makes tire selection more straightforward, with the next step becoming comparison of load specification, tire series, and intended use within the correct 17-inch size.
The LTZ Z71 can use either 265/65R18 or 265/70R17, so this sub-model requires especially careful confirmation of wheel diameter before any tire decision is made. Once the wheel size is verified, selection becomes a matter of staying with the proper package and matching the truck's road or light off-road use.
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.

Owners of a 2013 Chevrolet Trucks Silverado 1500 LTZ usually need to sort out exact tire size, wheel diameter, and sub-model fitment first. The questions below focus on LTZ size differences, product selection, and the checks that matter before regular road use.
Tire Size & Fitment
What tire size fits a 2013 Chevrolet Trucks Silverado 1500 LTZ?
The 2013 Chevrolet Trucks Silverado 1500 LTZ uses four possible tire sizes: 275/55R20, 245/70R17, 265/70R17, and 265/65R18. All are radial fitments, and the correct size depends on the truck's exact sub-model or wheel package rather than the LTZ badge alone.
The practical first step is checking the truck's current wheel diameter and existing tire size. A 20-inch option truck uses a different fitment from a 17-inch or 18-inch LTZ, and some 4x2, 4x4, and Z71 versions overlap only partly, so the right choice starts with confirming the exact setup on the vehicle.
What size rim does a 2013 Chevrolet Trucks Silverado 1500 LTZ use?
A 2013 Chevrolet Trucks Silverado 1500 LTZ may use 17-inch, 18-inch, or 20-inch rims, depending on the sub-model and wheel package. The associated tire sizes are 245/70R17 and 265/70R17 on 17-inch rims, 265/65R18 on 18-inch rims, and 275/55R20 on 20-inch rims.
Rim diameter should be confirmed before comparing tires, because tires for different wheel diameters are not interchangeable. Once the wheel size is verified, the next checks are the exact tire size already on the truck, the wheel width where relevant, and any changes from stock wheels that could affect fitment or clearance.
Why does the 2013 Chevrolet Trucks Silverado 1500 LTZ have more than one tire size?
The 2013 Chevrolet Trucks Silverado 1500 LTZ has more than one tire size because fitment varies by drivetrain, package, and wheel option. This LTZ range includes 17-inch, 18-inch, and 20-inch wheel-and-tire combinations, so different trucks wearing the same LTZ trim name may not use the same size.
That variation means tire selection should not be based on trim level alone. Checking whether the truck is a 4x2, 4x4, Z71, or 20 Inch Option version helps narrow the fitment, but the safest next step is still reading the size from the tires already on the truck and confirming the wheel diameter directly.
Choosing the Right Tire
What should I consider when choosing a tire for a 2013 Chevrolet Trucks Silverado 1500 LTZ?
Start with the exact tire size and wheel diameter used on the truck, because the 2013 Chevrolet Trucks Silverado 1500 LTZ can take several different radial fitments. After that, compare practical factors such as load capacity, rim-width compatibility, tire weight, and whether the truck is used mainly on pavement or sees light off-road duty.
A truck using 17-inch tires may also have more than one size within that rim diameter, so section width matters too. It helps to match the replacement tire to how the Silverado is actually driven, then confirm that the tire's specifications and dimensions suit the truck's wheel setup without assuming every LTZ configuration uses the same package.
What sidewall styles are available for 2013 Chevrolet Trucks Silverado 1500 LTZ tires?
The available 17-inch product options for this Silverado 1500 LTZ use RWL sidewalls, which is raised white letter styling. That gives the tire a more traditional light-truck appearance than a plain blackwall and is part of the visual character of the BFGoodrich All-Terrain T/A KO2 options offered in applicable sizes.
Sidewall style matters mostly as an appearance choice once the correct size is established. On a Silverado LTZ, raised white letters can suit a truck with a more utility-focused or off-road-influenced presentation, but the sidewall treatment should come after the core fitment checks of wheel diameter, tire size, and the load specification appropriate for the truck.
What brands offer tires for the 2013 Chevrolet Trucks Silverado 1500 LTZ?
The available products for the applicable 17-inch Silverado 1500 LTZ sizes here come from BFGoodrich. Those options are in the All-Terrain T/A KO2 series and cover 245/70R17 as well as 265/70R17, with multiple specification levels available in the 265/70R17 size.
Brand is only one part of the decision, especially on a truck with several possible factory-style size combinations. It still makes sense to compare the tire's size, load figure, rim-width range, and intended use first, since a well-matched specification matters more than choosing by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2013 Chevrolet Trucks Silverado 1500 LTZ?
For a period-style 2013 Chevrolet Trucks Silverado 1500 LTZ, the first priority is staying with the correct size for the truck's actual wheel package. Since this Silverado uses modern radial sizes rather than vintage bias-ply fitments, the right visual starting point is the proper 17-inch, 18-inch, or 20-inch size tied to the sub-model.
Appearance should be balanced with how the truck is used today. A utility-oriented all-terrain radial can support a more truck-focused presentation, but owners pursuing strict originality should compare the truck's current setup with window-sticker, dealer, or marque-specific references before treating any one size or sidewall style as the definitive factory presentation.
Does correct tire fitment matter for a 2013 Chevrolet Trucks Silverado 1500 LTZ restoration?
Correct tire fitment matters because it affects both the truck's appearance and the relationship between the body, wheel openings, and wheel package. On a 2013 Chevrolet Trucks Silverado 1500 LTZ, using the proper radial size for the sub-model keeps the truck visually aligned with its intended 17-inch, 18-inch, or 20-inch stance.
Fitment also matters mechanically, since the wrong wheel diameter or an incorrect size can complicate clearance and replacement planning. Even on a newer collector-era truck, it is worth confirming the exact LTZ configuration and present wheel setup before choosing tires so the finished result looks coherent and remains practical to drive.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2013 Chevrolet Trucks Silverado 1500 LTZ?
Yes, modifications can affect tire fitment on a 2013 Chevrolet Trucks Silverado 1500 LTZ. Aftermarket wheels, suspension lifts or drops, leveling kits, and body changes can alter the relationship between the tire, wheel opening, steering components, and suspension even when the tire size itself matches an LTZ fitment listed for a stock-style truck.
That matters most on a model with multiple factory wheel diameters already in play. A truck wearing non-original wheels should have its actual rim diameter and width checked first, then the owner should verify steering clearance and fender clearance at full turn and suspension movement before settling on any replacement tire.
What should I inspect before driving a 2013 Chevrolet Trucks Silverado 1500 LTZ on new tires?
Before regular driving, inspect tire pressure, sidewall condition, tread condition, valve stems, and the wheel hardware on the 2013 Chevrolet Trucks Silverado 1500 LTZ. It is also worth confirming that all four tires match the intended size for the truck and that there are no signs of rubbing, cuts, bulges, or slow air loss.
A short, careful road test can reveal issues that are easy to miss while parked. Pay attention to steering feel, any vibration, and whether the tires remain clear of suspension and fender surfaces during turns, since this LTZ range uses several different wheel-and-tire packages and correct installation matters just as much as the size itself.
How often should tires on a 2013 Chevrolet Trucks Silverado 1500 LTZ be inspected?
Tires on a 2013 Chevrolet Trucks Silverado 1500 LTZ should be inspected regularly, not just when tread looks low. Pressure, tread wear, sidewall condition, and any signs of impact damage or air loss deserve routine checks, especially on a truck that tows, hauls, sits for long periods, or sees rougher road conditions.
Frequent inspection helps catch problems before they turn into vibration, uneven wear, or roadside trouble. It is smart to look over the tires before longer drives, after seasonal storage, and anytime the truck's wheel or suspension setup has changed, since those factors can influence how well the chosen LTZ tire size continues to work.
