The 2011 Chevrolet Trucks Silverado 1500 LT sits in the modern full-size pickup era where daily usability, work capability, and trim-specific wheel packages all shape tire choice. On this truck, tire selection is less about vintage construction and more about confirming the exact wheel and sub-model setup first. The 2011 Chevrolet Trucks Silverado 1500 LT uses radial tire fitments that span 17-inch, 18-inch, and 20-inch rim packages, with sizes including 245/70R17, 265/70R17, 265/65R18, and 275/55R20. Available product coverage here leans toward all-terrain radial choices in selected 17-inch sizes. The key is matching the truck's exact configuration before comparing load, rim-width compatibility, and intended road or light-trail use.
Which Tire Size Is Right for The 2011 Chevrolet Trucks Silverado 1500 LT
Four primary tire sizes apply to the 2011 Chevrolet Trucks Silverado 1500 LT, and the correct one depends on the truck's exact sub-model and wheel package. Some versions share the same 17-inch fitments, while Z71 and 20 Inch Option trucks use different sizes on 18-inch or 20-inch rims. Start by confirming the sub-model and actual rim diameter on the truck before comparing tire choices.
The 275/55R20 size uses a 275-millimeter section width, a 55-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2011 Chevrolet Trucks Silverado 1500 LT, this size belongs to the 20 Inch Option configuration, so it is tied closely to that wheel package rather than the broader LT range. Its lower-profile metric layout gives it a different fitment context than the truck's 17-inch sizes. Choosing this size starts with confirming that the truck actually carries the 20-inch setup and has not been changed to another wheel diameter.
The 245/70R17 size is a metric radial with a 245-millimeter section width, a 70-series profile, and a 17-inch rim diameter. It appears on certain 2011 Chevrolet Trucks Silverado 1500 LT 4x2 and 4x4 configurations, making it one of the truck's standard 17-inch fitments rather than a universal size across every LT variation. Product availability in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewall styling. This size is worth considering when the truck uses the narrower 17-inch fitment and the goal is an all-terrain look with load-conscious light truck specifications.
The 265/70R17 size combines a 265-millimeter section width with a 70-series profile, radial construction, and a 17-inch rim. It is the broadest 17-inch fitment across this 2011 Chevrolet Trucks Silverado 1500 LT range, appearing on 4x2, 4x4, 4x4 Ext. Cab Long Box, and some Z71 trucks. Available products in this size include BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls and different load-capacity specifications. This is the size to evaluate when the truck carries a 17-inch wheel package and needs the wider of the covered 17-inch LT tire choices.
The 265/65R18 size uses a 265-millimeter section width, a 65-series aspect ratio, radial construction, and an 18-inch rim diameter. On the 2011 Chevrolet Trucks Silverado 1500 LT, it applies to certain Z71 trucks, so it reflects a trim-specific fitment rather than something shared by every LT model. Its metric radial format is familiar to modern truck owners, but its role here is defined by the truck's 18-inch wheel package. Choosing it begins with verifying that the Silverado is the Z71 configuration using 18-inch wheels rather than a 17-inch or 20-inch setup.
2011 Chevrolet Trucks Silverado 1500 LT Sub-Model Tires
Tire fitment on the 2011 Chevrolet Trucks Silverado 1500 LT varies by sub-model and wheel package, so the truck's exact configuration matters before any tire is selected. Some versions share 17-inch radial sizes, while others move to dedicated 18-inch or 20-inch fitments.

2011 Chevrolet Trucks Silverado 1500 LT (20 Inch Option)
The 20 Inch Option uses the 275/55R20 radial fitment, which separates it from the truck's 17-inch and 18-inch versions. Tire selection here starts with confirming the 20-inch wheel package and then choosing a tire that suits the truck's intended street, utility, or appearance goals.
The 4x2 configuration can use either 245/70R17 or 265/70R17, both in radial construction on 17-inch rims. That makes wheel and existing tire verification especially important before replacement, since the real choice is not just brand or tread style but confirming which 17-inch size is already on the truck.
The 4x4 version also spans two 17-inch radial sizes, 245/70R17 and 265/70R17. Tire selection should begin with the current wheel and size setup, then move to practical factors such as all-terrain needs, rim-width compatibility, and the load specification that best matches how the truck is used.
2011 Chevrolet Trucks Silverado 1500 LT 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 the broader 4x2 and 4x4 listings. Once that size is confirmed on the truck, the next step is comparing available 17-inch products by load specification and intended on-road or mixed-use duty.
The Z71 can use either 265/65R18 or 265/70R17, so confirming the actual wheel diameter is essential before choosing a tire. That wheel-package difference matters more than trim name alone, especially if the truck has changed wheels at some point in its service life.
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 LT Tires for Sale
Available product coverage for the 2011 Chevrolet Trucks Silverado 1500 LT centers on 17-inch radial all-terrain tires from BFGoodrich. The current choices use the All-Terrain T/A KO2 series with raised white letter sidewalls, while 245/70R17 and 265/70R17 differ in rim-width compatibility and load specification.
Owners of a 2011 Chevrolet Trucks Silverado 1500 LT usually need to sort out the exact tire size, wheel diameter, and sub-model first. The questions below focus on fitment, 17-inch product choices, sidewall style, and the practical checks that matter before road use.
Tire Size & Fitment
What tire size fits a 2011 Chevrolet Trucks Silverado 1500 LT?
The 2011 Chevrolet Trucks Silverado 1500 LT uses four primary radial tire sizes: 245/70R17, 265/70R17, 265/65R18, and 275/55R20. The correct size depends on the truck's specific sub-model and wheel package, not simply the LT badge alone.
The most important first step is confirming the truck's actual rim diameter and configuration. A 4x2 or 4x4 truck may use one of two 17-inch sizes, a Z71 may use either a 17-inch or 18-inch setup, and the 20 Inch Option uses its own 20-inch fitment.
What size rim does a 2011 Chevrolet Trucks Silverado 1500 LT use?
The 2011 Chevrolet Trucks Silverado 1500 LT appears with 17-inch, 18-inch, and 20-inch rim diameters depending on the version of the truck. The tire sizes tied to those rims are 245/70R17 and 265/70R17 on 17-inch wheels, 265/65R18 on 18-inch wheels, and 275/55R20 on 20-inch wheels.
That rim difference is critical because tire size selection starts with wheel diameter, not appearance alone. Checking the truck's current wheel setup is especially important on used Silverados, since wheel swaps are common and the sub-model name by itself does not always tell the whole fitment story.
Why does the 2011 Chevrolet Trucks Silverado 1500 LT have more than one tire size?
The 2011 Chevrolet Trucks Silverado 1500 LT has more than one tire size because fitment changes with sub-model and wheel package. The LT range includes trucks on 17-inch wheels, a Z71 configuration that can use 17-inch or 18-inch sizes, and a separate 20 Inch Option with its own 20-inch tire.
That means tire selection is really a configuration question first and a product question second. Before comparing tread pattern, sidewall style, or load rating, verify the truck's exact sub-model, then confirm the wheel diameter and the size already mounted so the replacement path stays consistent.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2011 Chevrolet Trucks Silverado 1500 LT?
A 265/70R17 tire for the 2011 Chevrolet Trucks Silverado 1500 LT should first match the truck's actual 17-inch fitment. In the available product range, this size appears in BFGoodrich All-Terrain T/A KO2 form with raised white letter sidewalls and more than one load-capacity specification.
Selection then comes down to how the truck is used and what wheel it carries. Compare rim-width compatibility, load rating, and whether the truck sees mostly street miles or mixed on-road and unpaved use, since those details matter more than choosing by size code alone.
What sidewall styles are available for 2011 Chevrolet Trucks Silverado 1500 LT tires?
The currently covered 17-inch product options for the 2011 Chevrolet Trucks Silverado 1500 LT use RWL sidewalls, which means raised white letters. That styling appears on the BFGoodrich All-Terrain T/A KO2 products available in 245/70R17 and 265/70R17.
Sidewall treatment affects the truck's visual presentation more than fitment, but it is still worth considering before purchase. A raised white letter tire gives the Silverado a more traditional truck look, while the more important technical checks remain the correct size, wheel diameter, and load specification.
What brands offer tires for the 2011 Chevrolet Trucks Silverado 1500 LT?
The currently available products for covered 17-inch Silverado 1500 LT fitments come from BFGoodrich. Those options are in the All-Terrain T/A KO2 series for 245/70R17 and 265/70R17 sizes, both using radial construction and raised white letter sidewalls.
Brand is only one part of the decision on this truck. It still makes sense to verify the exact size on the Silverado first, then compare the available BFGoodrich options by rim-width range, load capacity, and whether the truck needs a light-duty or heavier-duty 17-inch tire setup.
Restoration & Appearance
Which tire should I choose for a period-style 2011 Chevrolet Trucks Silverado 1500 LT?
A period-style choice for a 2011 Chevrolet Trucks Silverado 1500 LT starts with keeping the truck in its correct original-size family for the wheel package already on it. For the covered 17-inch options, BFGoodrich All-Terrain T/A KO2 tires present a traditional truck-oriented look with modern radial construction.
Appearance should come after the fitment basics are settled. Confirm whether the truck uses 17-inch, 18-inch, or 20-inch wheels, then choose a size and sidewall treatment that suit the Silverado's era and purpose without drifting away from the wheel diameter and clearance requirements already built into the truck.
Which sidewall style suits a period-style 2011 Chevrolet Trucks Silverado 1500 LT?
For the currently covered 17-inch tire options, raised white letter sidewalls are the available appearance choice for a 2011 Chevrolet Trucks Silverado 1500 LT. That look suits many trucks from this era because it keeps a familiar sport-truck or all-terrain visual character without changing the tire's basic radial fitment format.
The right appearance still depends on how the truck is being presented. A cleaner street look, a utility-focused setup, or a more off-road-inspired stance can all influence sidewall preference, but the visual decision should always follow the correct tire size, wheel diameter, and load needs for the truck.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 Chevrolet Trucks Silverado 1500 LT?
Yes, modifications can affect tire fitment on a 2011 Chevrolet Trucks Silverado 1500 LT. Aftermarket wheels, different offsets, suspension lifts or lowering, and body or fender changes can alter the clearance relationship around sizes such as 245/70R17, 265/70R17, 265/65R18, or 275/55R20.
The safest approach is to confirm the actual wheel diameter and width on the truck before replacing tires. It also helps to check turning clearance, suspension travel, and any signs of rubbing, especially on used trucks where the current setup may no longer match the original wheel package.
What should I inspect before driving a 2011 Chevrolet Trucks Silverado 1500 LT on new tires?
Before driving a 2011 Chevrolet Trucks Silverado 1500 LT on new tires, inspect the wheel condition, lug hardware, inflation pressure, and the tire sidewalls and tread for any mounting or shipping damage. It also makes sense to verify that all four tires match the intended size and wheel diameter for the truck.
A short initial road check can help confirm that the steering feels normal and that no rubbing appears at full lock or over bumps. Rechecking pressure after the first drives is useful, particularly on a truck that may alternate between unloaded use and heavier work or towing conditions.
What should I check before a longer drive in a 2011 Chevrolet Trucks Silverado 1500 LT?
Before a longer drive in a 2011 Chevrolet Trucks Silverado 1500 LT, check inflation pressure, tread condition, visible cuts or bulges, and any uneven wear that could point to alignment or suspension issues. The truck should also be carrying the correct tire size for its wheel diameter and sub-model setup.
Longer trips put more emphasis on consistency and stability, so it helps to confirm that the tires are evenly matched side to side and front to rear where appropriate. A quick inspection of spare condition, valve stems, and air retention can prevent avoidable roadside trouble on a full-size pickup.
