The 2011 Chevrolet Trucks Silverado 1500 LTZ sits in the later GMT900 era, when full-size pickups balanced everyday comfort with real work and trail capability. In LTZ trim, the Silverado carried a more upscale presentation, but tire choice still depends heavily on the exact wheel package and sub-model. This truck uses radial tires, with fitments including 245/70R17, 265/70R17, 265/65R18, and 275/55R20. That means the key decision is not just brand, but confirming whether your truck has 17-, 18-, or 20-inch wheels and whether it is a Z71, 4x2, 4x4, or 20 Inch Option configuration. Getting that right helps preserve stance, clearance, and intended use.
Which Tire Size Is Right for The 2011 Chevrolet Trucks Silverado 1500 LTZ
The 2011 Chevrolet Trucks Silverado 1500 LTZ uses four primary tire sizes, and the right one depends on the exact sub-model and wheel package. Fitment varies across 17-inch, 18-inch, and 20-inch rims, so the first step is confirming both the specific LTZ configuration and the wheel diameter currently on the truck before comparing tire choices.
A 275/55R20 tire uses a 275 millimeter section width, a 55-series aspect ratio, radial construction, and a 20-inch rim. On the 2011 Chevrolet Trucks Silverado 1500 LTZ, this size is tied to the 20 Inch Option and gives the truck a distinctly larger-wheel fitment than the 17-inch alternatives. The practical decision here is less about construction and more about verifying that the truck actually has the 20-inch wheel setup before selecting a replacement. This size is the right place to start when maintaining the truck's existing wheel-and-tire proportion.
A 245/70R17 tire is a metric radial size with a 245 millimeter section width, a 70-series profile, and a 17-inch rim. On the 2011 Chevrolet Trucks Silverado 1500 LTZ, it appears on certain 4x2 and 4x4 configurations, so it should not be treated as universal across every LTZ. Available product coverage in this size includes an LT245/70R17/E BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls. This size is worth evaluating when the truck is already on 17-inch wheels and the goal is to stay with a narrower all-terrain-style fitment.
A 265/70R17 tire uses a 265 millimeter section width, a 70-series profile, radial construction, and a 17-inch rim. It is the broadest 17-inch fitment used across the 2011 Chevrolet Trucks Silverado 1500 LTZ lineup, appearing on certain 4x2, 4x4, extended-cab long-box, and Z71 applications. BFGoodrich offers this size in the All-Terrain T/A KO2 series with raised white letter sidewalls, including versions with different load capacities. This size deserves a closer look when keeping a 17-inch wheel setup and matching the truck's actual configuration and intended use matter more than appearance alone.
A 265/65R18 tire combines a 265 millimeter section width, a 65-series aspect ratio, radial construction, and an 18-inch rim. On the 2011 Chevrolet Trucks Silverado 1500 LTZ, this size is associated with the Z71, making it a configuration-specific fitment rather than a general LTZ default. Its role in the lineup sits between the 17-inch and 20-inch wheel packages, so wheel confirmation is essential before moving ahead. This size is the correct starting point when a Silverado LTZ Z71 still wears its 18-inch setup and the goal is to preserve that overall fitment profile.
2011 Chevrolet Trucks Silverado 1500 LTZ Sub-Model Tires
Sub-model fitment on the 2011 Chevrolet Trucks Silverado 1500 LTZ is not one-size-fits-all. Tire selection depends on whether the truck is a 20 Inch Option, 4x2, 4x4, 4x4 Ext. Cab Long Box, or Z71, and in several cases the wheel diameter changes with the tire size.

2011 Chevrolet Trucks Silverado 1500 LTZ (20 Inch Option)
The 20 Inch Option uses the 275/55R20 radial fitment, which sets it apart from the 17-inch and 18-inch LTZ configurations. Tire shopping for this version starts with confirming that the truck still has its 20-inch wheel package rather than assuming all LTZ models share the same setup.
The Silverado 1500 LTZ 4x2 uses 17-inch radial tire fitments and may appear with either 245/70R17 or 265/70R17. That makes wheel and existing tire verification important before replacement, especially if the truck has been changed from its original wheel-and-tire combination.
The Silverado 1500 LTZ 4x4 also uses 17-inch radial fitments and can be equipped with either 245/70R17 or 265/70R17. The practical choice is confirming which of those two sizes is actually on the truck now, then comparing load range, sidewall treatment, and intended use within that size.
2011 Chevrolet Trucks Silverado 1500 LTZ 4x4 Ext. Cab Long Box
The 4x4 Ext. Cab Long Box uses the 265/70R17 radial size, giving it a more straightforward fitment path than some other LTZ configurations. Selection then becomes a matter of choosing the right product within that size and making sure the wheel remains the correct 17-inch setup.
The Silverado 1500 LTZ Z71 can use either 265/65R18 or 265/70R17, so exact wheel package confirmation matters before choosing a tire. That variation means a Z71 owner should identify the installed rim diameter first, then compare tire options that suit the truck's road and 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.
Best 2011 Chevrolet Trucks Silverado 1500 LTZ Tires for Sale
Available products for the 2011 Chevrolet Trucks Silverado 1500 LTZ center on 17-inch BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls. The main comparison points are size, load specification, weight, and rim-width compatibility within the truck's 245/70R17 and 265/70R17 fitments.
Tire questions for the 2011 Chevrolet Trucks Silverado 1500 LTZ usually come down to exact size, wheel diameter, sub-model differences, and how to choose the right radial tire for the truck's intended use. These answers also cover appearance, maintenance, and fitment checks before road use.
Tire Size & Fitment
What tire size fits a 2011 Chevrolet Trucks Silverado 1500 LTZ?
The 2011 Chevrolet Trucks Silverado 1500 LTZ uses more than one tire size. Depending on the exact configuration, the primary sizes are 245/70R17, 265/70R17, 265/65R18, and 275/55R20, and all of them are radial fitments tied to specific wheel packages or sub-models.
The safest starting point is the truck itself rather than the trim badge alone. Check the current tire size, confirm the wheel diameter, and match that against whether the truck is a 4x2, 4x4, Z71, 4x4 Ext. Cab Long Box, or 20 Inch Option before comparing replacement tires.
What size rim does a 2011 Chevrolet Trucks Silverado 1500 LTZ use?
A 2011 Chevrolet Trucks Silverado 1500 LTZ can use 17-inch, 18-inch, or 20-inch rims, depending on the exact sub-model and wheel package. The 17-inch fitments pair with 245/70R17 or 265/70R17, the 18-inch fitment pairs with 265/65R18, and the 20-inch option uses 275/55R20.
Rim diameter needs to be confirmed before anything else because the LTZ does not share one universal wheel size. Looking at the existing tire sidewall or measuring the wheel is especially important on trucks that may have had aftermarket wheels or take-off wheel packages installed at some point.
Why does the 2011 Chevrolet Trucks Silverado 1500 LTZ have more than one tire size?
The 2011 Chevrolet Trucks Silverado 1500 LTZ has multiple tire sizes because fitment changes with the truck's sub-model and wheel package. A 20 Inch Option truck uses 275/55R20, Z71 models can use 265/65R18 or 265/70R17, and other 4x2 or 4x4 versions may use 245/70R17 or 265/70R17.
That variation means the trim name alone is not enough to choose a tire. Identifying the exact LTZ configuration and confirming the wheel diameter helps prevent ordering a tire that matches the badge but not the actual truck setup, stance, or intended clearance around the suspension and body.
Choosing the Right Tire
What should I consider when choosing a tire for a 2011 Chevrolet Trucks Silverado 1500 LTZ?
Start with the correct size for the truck's exact configuration, since the 2011 Chevrolet Trucks Silverado 1500 LTZ uses four different radial fitments. The main sizes are spread across 17-inch, 18-inch, and 20-inch wheel packages, so the first decision is always matching the tire to the actual wheel diameter and sub-model.
After size is confirmed, compare the tire's intended use and specifications. On the available 17-inch products, that means looking at details such as load capacity, rim-width range, tire weight, and whether an all-terrain radial with raised white letter sidewalls suits how the truck is driven and presented.
What sidewall styles are available for 2011 Chevrolet Trucks Silverado 1500 LTZ tires?
The available 17-inch products for the 2011 Chevrolet Trucks Silverado 1500 LTZ use RWL sidewalls, which means raised white letter styling. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options offered in both 245/70R17 and 265/70R17 sizes.
Sidewall style affects the truck's visual character as much as the tire itself. Raised white letters give the Silverado a more assertive, truck-oriented presentation, so buyers concerned with appearance should confirm whether that look matches the vehicle's current style before choosing between available fitments and load specifications.
What brands offer tires for the 2011 Chevrolet Trucks Silverado 1500 LTZ?
BFGoodrich is represented in the available product selection for the 2011 Chevrolet Trucks Silverado 1500 LTZ. The current covered options are from the All-Terrain T/A KO2 series in 245/70R17 and 265/70R17, both in radial construction with raised white letter sidewalls.
Brand comparison only matters after the truck's correct size is pinned down, since LTZ fitment varies by wheel package. A truck on 17-inch wheels can then be compared by KO2 specification details such as load rating, rim-width range, and tire weight rather than by name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Chevrolet Trucks Silverado 1500 LTZ?
A period-style approach for a 2011 Chevrolet Trucks Silverado 1500 LTZ starts with retaining the truck's correct size and wheel diameter for its exact configuration. Since this is a modern full-size pickup with radial fitments, preserving the proper 17-inch, 18-inch, or 20-inch package matters more than chasing a vintage-style construction change.
Appearance choices should follow the truck's existing character. An LTZ on 17-inch wheels can be kept in a more truck-focused visual direction with the available BFGoodrich All-Terrain T/A KO2 and raised white letters, while trucks on 18-inch or 20-inch wheels benefit from staying true to their present wheel-and-tire proportion.
Does correct tire fitment matter for a 2011 Chevrolet Trucks Silverado 1500 LTZ restoration?
Correct tire fitment matters because the 2011 Chevrolet Trucks Silverado 1500 LTZ was offered with several legitimate wheel-and-tire combinations. Using the wrong rim diameter or the wrong size for the truck's specific sub-model can change its stance, alter its visual balance, and complicate proper replacement planning.
A restoration-minded owner should first determine which wheel package belongs on that particular truck, then choose a tire that matches that setup. For exact originality questions beyond basic size and wheel compatibility, vehicle-specific documentation and marque-focused references are the right place to verify finer appearance details.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Chevrolet Trucks Silverado 1500 LTZ?
Yes, modifications can affect tire fitment on a 2011 Chevrolet Trucks Silverado 1500 LTZ. Aftermarket wheels, suspension lifts, lowering changes, altered offsets, or non-stock wheel widths can all change how a 245/70R17, 265/70R17, 265/65R18, or 275/55R20 tire sits in the wheel opening.
A truck that has been changed from stock should be checked as an individual setup before replacement. Wheel diameter is only part of the picture, so it also helps to verify rim width, steering clearance, fender clearance, and any signs that the present tire is already close to rubbing under suspension movement.
What should I inspect before driving a 2011 Chevrolet Trucks Silverado 1500 LTZ on new tires?
Before road use, inspect tire pressure, lug nut torque, visible seating on the wheel, and basic clearance at the fenders and suspension. A 2011 Chevrolet Trucks Silverado 1500 LTZ should also be checked for cuts, bulges, or irregularities that may have occurred during mounting or from earlier wheel-related issues.
A short initial drive followed by a second inspection is a smart habit on a truck with multiple possible wheel packages. Recheck for air loss, look for any signs of contact during turning or suspension movement, and make sure the selected tire's load specification suits how the Silverado is actually used.
How should tires on a 2011 Chevrolet Trucks Silverado 1500 LTZ be maintained?
Tires on a 2011 Chevrolet Trucks Silverado 1500 LTZ should be maintained with regular pressure checks, visual inspections, and attention to tread wear across the full width of the tire. Any truck that sees mixed highway and utility use also benefits from watching for uneven wear that may point to alignment or suspension issues.
Maintenance is especially important when the truck sits for longer periods or is used seasonally. Keeping the tires properly inflated, storing the vehicle away from prolonged heat and sunlight when possible, and checking for cracking, flat spotting, or slow air loss all help preserve fitment and road readiness.
