The 2006 Chevrolet Trucks Silverado 1500 LS sits in the era when full-size pickups were expected to handle daily driving, work duty, and weekend use with equal ease. Buyers often chose them for their straightforward durability, familiar GMT800 proportions, and broad range of wheel and drivetrain configurations. Tire selection on this exact Silverado 1500 LS centers on three radial sizes: 245/70R17, 265/70R17, and the 20-inch-option 275/55R20. That makes the real decision less about old-style bias-ply versus radial construction and more about confirming the truck's exact sub-model and wheel diameter, then choosing the right load range, series, and sidewall presentation for how the truck is actually used.
Which Tire Size Is Right for The 2006 Chevrolet Trucks Silverado 1500 LS
The 2006 Chevrolet Trucks Silverado 1500 LS uses three primary tire sizes, and they do not all apply to the same configuration. Fitment varies by sub-model and wheel setup, with both 17-inch and 20-inch rim diameters in use. The first step is identifying whether the truck is a 4x2, a 4x4, or the 20 Inch Option, then confirming the actual wheel diameter before comparing tire choices.
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 2006 Chevrolet Trucks Silverado 1500 LS, this size belongs to the 20 Inch Option and gives the truck a distinctly different fitment path than the 17-inch configurations. Its lower-profile metric format is more modern in presentation than the taller 17-inch sizes used elsewhere in the LS range. Choosing this size starts with confirming that the truck actually has the 20-inch wheel setup, since rim diameter alone separates it from the other primary Silverado 1500 LS fitments.
A 245/70R17 tire uses a 245-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 17-inch rim. On the 2006 Chevrolet Trucks Silverado 1500 LS, this size appears on certain 4x2 configurations rather than across the entire model line. Available product choice in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls, adding a more truck-oriented look along with its LT construction. This size is worth evaluating when the truck retains its original 17-inch wheel diameter and the goal is to stay with the narrower of the two 17-inch Silverado LS fitments.
A 265/70R17 tire uses a 265-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 17-inch rim. This is the shared 17-inch fitment for the 2006 Chevrolet Trucks Silverado 1500 LS 4x4 and also one of the fitment options for the 4x2. BFGoodrich offers this size in the All-Terrain T/A KO2 series with raised white letter sidewalls, and the available versions differ in load capacity and weight. It is the size to examine closely when the truck runs 17-inch wheels and needs the broader of the two LS fitments used across the 4x2 and 4x4 range.
2006 Chevrolet Trucks Silverado 1500 LS Sub-Model Tires
Sub-model fitment matters on the 2006 Chevrolet Trucks Silverado 1500 LS because tire size changes with drivetrain and wheel package. Some versions share a 17-inch rim diameter, but the exact tire size still varies, while the 20 Inch Option follows its own separate fitment.

2006 Chevrolet Trucks Silverado 1500 LS (20 Inch Option)
The 20 Inch Option uses a dedicated 20-inch radial fitment rather than either of the 17-inch Silverado LS sizes. Tire selection here starts with keeping that wheel diameter in mind, then comparing products that suit the truck's intended road use and appearance.
The 4x2 version is the most important Silverado 1500 LS sub-model to verify because it can use either of two different 17-inch radial sizes. Choosing correctly means confirming the actual wheel and tire setup on the truck before comparing load range, series, or sidewall details.
The 4x4 uses a single 17-inch radial fitment, which makes sizing more straightforward than on the 4x2. The focus then shifts from identifying the right primary size to selecting the product characteristics that match the truck's use, wheel width, and overall setup.
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 2006 Chevrolet Trucks Silverado 1500 LS Tires for sale
Available products for the 17-inch Silverado 1500 LS sizes center on BFGoodrich All-Terrain T/A KO2 radials with raised white letter sidewalls. The main comparison points are size, rim-width compatibility, load capacity, and the differences between the two 265/70R17 specifications.
Owners of a 2006 Chevrolet Trucks Silverado 1500 LS usually need to sort out sub-model tire sizing first, then compare 17-inch versus 20-inch fitment, radial construction, product specifications, and practical checks before putting the truck back on the road.
Tire Size & Fitment
What tire size fits a 2006 Chevrolet Trucks Silverado 1500 LS?
The 2006 Chevrolet Trucks Silverado 1500 LS uses three primary tire sizes: 245/70R17, 265/70R17, and 275/55R20. These sizes do not all apply to the same truck configuration. The 20 Inch Option uses 275/55R20, the 4x4 uses 265/70R17, and the 4x2 can use either 245/70R17 or 265/70R17.
That means the first step is identifying the exact sub-model and confirming the wheel diameter already on the truck. A Silverado that has been changed over to different wheels or tires should be checked carefully before replacement, since the correct primary size depends on the actual 17-inch or 20-inch setup rather than the model name alone.
What size rim does a 2006 Chevrolet Trucks Silverado 1500 LS use?
A 2006 Chevrolet Trucks Silverado 1500 LS uses either a 17-inch or 20-inch rim, depending on configuration. The 245/70R17 and 265/70R17 fitments both use 17-inch rims, while the 275/55R20 fitment uses a 20-inch rim on the 20 Inch Option.
Rim diameter is the quickest way to narrow the fitment because a 17-inch tire cannot be mounted on a 20-inch wheel, and vice versa. It is also worth confirming wheel width before selecting a specific product, especially on trucks that may have aftermarket wheels, since product compatibility within the correct rim diameter can still vary.
Why does the 2006 Chevrolet Trucks Silverado 1500 LS have more than one tire size?
More than one tire size appears on the 2006 Chevrolet Trucks Silverado 1500 LS because fitment changes with sub-model and wheel package. The 4x2 can use two different 17-inch sizes, the 4x4 uses one 17-inch size, and the 20 Inch Option moves to a different size on a larger wheel.
That variation makes it important to verify the truck itself instead of choosing a tire by year and model alone. Checking the sidewall on the current tire, measuring the wheel diameter, and confirming whether the truck is a 4x2, 4x4, or 20 Inch Option will prevent mixing up sizes that belong to different Silverado LS configurations.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Chevrolet Trucks Silverado 1500 LS?
Start with the correct primary tire size for the truck's exact configuration: 245/70R17, 265/70R17, or 275/55R20. After that, compare radial construction details that matter in actual use, including wheel diameter, rim-width compatibility, load capacity, and whether the truck is being used more for highway driving, mixed use, or a more truck-oriented all-terrain role.
Product selection also depends on the setup already on the vehicle. A Silverado LS with factory-style 17-inch wheels calls for a different decision process than one wearing the 20-inch option, and a truck with wheel changes should be checked closely so the chosen tire matches the rim width and clears the suspension and bodywork properly.
What sidewall styles are available for 2006 Chevrolet Trucks Silverado 1500 LS tires?
The available 17-inch products for the 2006 Chevrolet Trucks Silverado 1500 LS use RWL sidewalls, which means raised white letter styling. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options offered in 245/70R17 and 265/70R17.
Sidewall appearance matters because it changes the truck's presentation even when the tire size stays the same. Raised white letters tend to give the Silverado a more assertive period-appropriate truck look, so buyers who care about appearance should compare sidewall treatment along with size, load specification, and the way the truck is actually driven.
What tire series are available for the 2006 Chevrolet Trucks Silverado 1500 LS?
The available 17-inch products for the 2006 Chevrolet Trucks Silverado 1500 LS are in the BFGoodrich All-Terrain T/A KO2 series. That series appears in both 245/70R17 and 265/70R17, and the two 265/70R17 versions differ in weight and maximum load capacity rather than in tire series branding.
Looking at the series still matters because it helps set expectations about the tire's character and intended use. Once the correct size is confirmed, compare the exact specification within that series so the chosen tire matches the truck's wheel width, the load demands placed on it, and whether the goal is general road use or a more rugged all-terrain setup.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Chevrolet Trucks Silverado 1500 LS?
A period-style choice for a 2006 Chevrolet Trucks Silverado 1500 LS starts with the size that belongs to the truck's exact configuration. That means 245/70R17 or 265/70R17 on the 17-inch setups, or 275/55R20 on the 20 Inch Option, followed by a tread and sidewall presentation that suits the truck's original-era appearance.
For many Silverado owners, the visual decision is less about vintage construction and more about whether the tire looks appropriate on the truck's wheel package. Raised white letter all-terrain styling can suit the era well on a 17-inch setup, but owners chasing strict originality should compare the truck against period photos, sales literature, or marque-specific references.
How does tire construction affect the appearance of a restored 2006 Chevrolet Trucks Silverado 1500 LS?
Construction is straightforward on this truck because the primary fitments are radial across all three sizes. That means the appearance differences come less from bias-ply versus radial construction and more from tire size, tread style, sidewall treatment, and the visual relationship between the tire and the truck's 17-inch or 20-inch wheel package.
A restored Silverado 1500 LS can look notably different depending on whether it wears a taller 17-inch fitment or the lower-profile 20-inch option. Sidewall styling also matters, so owners focused on presentation should look closely at lettered sidewalls, overall tire stance, and wheel proportion rather than assuming any tire in the correct diameter creates the same finished look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Chevrolet Trucks Silverado 1500 LS?
Yes, modifications can affect tire fitment on a 2006 Chevrolet Trucks Silverado 1500 LS even when the size sounds close to the original setup. Wheel changes, altered wheel width, different offset, suspension lifts or lowering, and body modifications can all change how a 245/70R17, 265/70R17, or 275/55R20 tire sits and clears.
That is especially important on a truck where both 17-inch and 20-inch fitments exist. Checking the current wheel diameter, width, and overall clearance at full steering lock is a smart step before replacement, since the truck may no longer match its original LS configuration if previous owners changed the wheels or suspension.
What should I inspect before driving a 2006 Chevrolet Trucks Silverado 1500 LS on new tires?
Before road use, inspect the wheels for damage, confirm that the tire size matches the truck's actual configuration, and make sure the tires are inflated appropriately for their specification. It is also wise to look over suspension and steering components, because worn parts can affect how a new set of tires tracks, wears, and clears under load.
A close visual check should include sidewall condition, valve stems, lug hardware, and any signs of rubbing after installation. Taking the truck on a short, careful drive and then rechecking pressure and clearance can catch issues early, especially on Silverado LS trucks that may have seen wheel swaps, alignment changes, or years of intermittent use.
How often should tires on a 2006 Chevrolet Trucks Silverado 1500 LS be inspected?
Tires on a 2006 Chevrolet Trucks Silverado 1500 LS should be inspected regularly rather than only at replacement time. Monthly pressure checks are a good baseline, and the tires should also be looked over for uneven wear, cuts, bulges, cracking, punctures, or slow air loss before longer trips, seasonal use, or heavier hauling duty.
Inspection matters even more on an older truck that may not be driven every day. Periods of storage, infrequent use, or outdoor exposure can age tires in ways that are easy to miss at a glance, so checking tread condition, sidewall health, and general wheel-and-tire condition should be part of routine Silverado maintenance.
