The 2009 Chevrolet Trucks Silverado 1500 LT sits in the era when full-size pickups were expected to handle everyday work, weekend towing, and family use without giving up comfort or road presence. That broad mission shows up clearly in its tire fitment, because this exact Silverado 1500 LT can use four different radial sizes depending on sub-model and wheel package. Buyers may be sorting between 17-inch, 18-inch, and 20-inch setups, with some configurations also bringing a more truck-oriented all-terrain product choice into the picture. The right decision starts with confirming the exact LT configuration and wheel diameter before comparing appearance, load capacity, and intended use.
Which Tire Size Is Right for The 2009 Chevrolet Trucks Silverado 1500 LT
The 2009 Chevrolet Trucks Silverado 1500 LT uses four primary tire sizes, and the correct 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 the truck's actual wheel diameter and whether it is a 4x2, 4x4, 20 Inch Option, Max Trailer Package, or Z71 Package configuration before choosing a tire.
275/55R20 is a modern metric radial size in which 275 indicates the section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On this Silverado 1500 LT, it belongs to specific 20-inch-wheel configurations rather than every truck in the model line. Its role is tied closely to wheel-package identification, since moving between rim diameters is not just a tire choice. This size should be evaluated only after confirming that the truck actually carries the 20-inch setup and has the clearance and wheel dimensions that match it.
245/70R17 is a metric radial size that uses a 245-millimeter section width, a 70-series profile, and a 17-inch rim. On the 2009 Silverado 1500 LT, this size appears on certain 4x2 and 4x4 applications and stays within the truck's radial-construction fitment pattern. Available product choice in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls and a 17-inch rim-width range of 6.5 to 8.0 inches. It is a size worth checking closely when the truck has a 17-inch wheel and the goal is maintaining the correct fitment category without stepping into another wheel package.
Fit(s): 4x2, 4x4, w/Max Trailer Pkg., and w/Z71 Pkg.
Construction: Radial|Rim: 17 in
265/70R17 is a metric radial tire size with a 265-millimeter section width, a 70-series profile, and a 17-inch rim diameter. It is one of the most broadly used sizes across this Silverado 1500 LT range, showing up on certain 4x2, 4x4, Max Trailer Package, and Z71 Package configurations. Product choice in this size includes BFGoodrich All-Terrain T/A KO2 tires in raised white letter form, with differing load-capacity versions and a rim-width range of 7.0 to 9.0 inches. This size makes sense to evaluate when the truck already has the correct 17-inch wheel and the owner wants to compare load specification and intended use within the same size family.
265/65R18 is a modern metric radial size in which 265 gives the nominal section width in millimeters, 65 is the aspect ratio, R marks radial construction, and 18 is the wheel diameter in inches. On this Silverado 1500 LT, it is tied to particular configurations such as the Z71 Package rather than to every LT truck. That makes wheel and package confirmation more important than comparing the size in isolation. Buyers considering this fitment should treat it as an 18-inch-specific application and verify that the truck's wheels and current setup match the intended size before moving ahead.
2009 Chevrolet Trucks Silverado 1500 LT Sub-Model Tires
Sub-model fitment is not uniform across the 2009 Chevrolet Trucks Silverado 1500 LT, and several configurations use different tire sizes or wheel diameters. Checking the exact LT version matters because a 17-inch setup, an 18-inch Z71 package, and a 20-inch option do not lead to the same tire choice.

2009 Chevrolet Trucks Silverado 1500 LT (20 Inch Option)
The 20 Inch Option uses a dedicated 20-inch radial fitment, which puts wheel diameter at the center of the tire decision. Tire selection here starts with confirming that the truck still has its 20-inch setup before comparing replacement choices against the vehicle's intended use and appearance.
The 4x2 configuration can use more than one 17-inch radial size, so the key is identifying the exact wheel and tire setup already on the truck. That makes this less about broad model-year fitment and more about matching the current configuration before selecting among available replacements.
The 4x4 version also uses 17-inch radial fitments, with more than one applicable size depending on the truck's exact setup. Tire selection should focus on the wheel diameter and current size on the vehicle so the replacement stays aligned with load needs, clearance, and intended driving conditions.
2009 Chevrolet Trucks Silverado 1500 LT w/Max Trailer Pkg.
The Max Trailer Package spans two different radial sizes across two different wheel diameters, so this is one of the configurations where quick assumptions cause mistakes. Choosing the right tire means confirming whether the truck is on the 17-inch or 20-inch setup before comparing product specifications.
2009 Chevrolet Trucks Silverado 1500 LT w/Z71 Pkg.
The Z71 Package uses either a 17-inch or 18-inch radial fitment, which makes wheel identification essential before shopping by size. Once that is settled, the decision shifts to selecting the tire that matches the truck's current stance, use, and wheel compatibility.
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 2009 Chevrolet Trucks Silverado 1500 LT?
The 2009 Chevrolet Trucks Silverado 1500 LT can use 275/55R20, 245/70R17, 265/70R17, or 265/65R18, all in radial construction. The correct size depends on the exact sub-model and wheel package, including 4x2, 4x4, 20 Inch Option, Max Trailer Package, and Z71 Package applications.
That means the right tire is determined by the truck's actual configuration, not just by the model name on the fender. Start by checking the current wheel diameter and the size already mounted, then match that against the truck's specific package so the replacement stays aligned with the intended fitment.
What size rim does a 2009 Chevrolet Trucks Silverado 1500 LT use?
A 2009 Chevrolet Trucks Silverado 1500 LT uses 17-inch, 18-inch, or 20-inch rims depending on configuration. The 245/70R17 and 265/70R17 sizes use 17-inch rims, 265/65R18 uses an 18-inch rim, and 275/55R20 uses a 20-inch rim.
Rim diameter is the first thing to verify because these tire sizes do not cross over from one wheel diameter to another. Checking the wheel itself, rather than assuming by trim name, helps avoid choosing a tire that belongs to a different package or wheel option on the same Silverado 1500 LT.
Why does the 2009 Chevrolet Trucks Silverado 1500 LT have more than one tire size?
This Silverado 1500 LT has more than one tire size because fitment changes with sub-model and equipment package. A 17-inch setup is common on several 4x2 and 4x4 applications, while certain Z71, Max Trailer Package, and 20 Inch Option trucks use different wheel-and-tire combinations.
That variety means the model year alone is not enough to choose a replacement. The practical approach is to identify the exact sub-model, confirm the wheel diameter on the truck, and then compare the correct size against the vehicle's present setup before selecting a new tire.
Choosing the Right Tire
What should I consider when choosing a tire for a 2009 Chevrolet Trucks Silverado 1500 LT?
Begin with the correct size for the truck's exact configuration, since this Silverado 1500 LT can use four different radial fitments across 17-inch, 18-inch, and 20-inch wheels. Once size is confirmed, compare construction, load-capacity specification, rim-width compatibility, and whether the truck is used more for everyday driving, towing, or mixed on-road and off-road duty.
Product details matter most when they affect how the tire will be used on the vehicle you actually have. A 17-inch all-terrain option with a different load specification may suit one Silverado setup better than another, so matching the tire to wheel size, package, and use is more important than choosing by appearance alone.
What sidewall styles are available for 2009 Chevrolet Trucks Silverado 1500 LT tires?
The available 17-inch products for this Silverado 1500 LT use RWL sidewalls, which means raised white letter styling. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options in both 245/70R17 and 265/70R17.
Sidewall style affects the truck's overall presentation even when the tire size stays the same. Raised white letters tend to give a more assertive truck look, but the fitment still needs to be chosen by the correct wheel diameter, sub-model, and tire specification before appearance details come into the final decision.
What brands offer tires for the 2009 Chevrolet Trucks Silverado 1500 LT?
The available products for the supported 17-inch sizes on this Silverado 1500 LT come from BFGoodrich. The current assortment includes BFGoodrich All-Terrain T/A KO2 options in 245/70R17 and 265/70R17, both using radial construction and raised white letter sidewalls.
Brand alone should not drive the choice unless the size and specification already match the truck. It is still important to compare the exact tire size, the wheel diameter on the vehicle, the load-capacity rating shown for the product, and the way the truck is expected to be used after installation.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Chevrolet Trucks Silverado 1500 LT?
A period-style choice for a 2009 Chevrolet Trucks Silverado 1500 LT starts with keeping the truck in its correct size and wheel-diameter family. For many trucks in this range, that means staying with the proper 17-inch, 18-inch, or 20-inch radial fitment that matches the exact LT configuration rather than changing the overall look through a different package size.
Appearance tends to stay more convincing when the tire matches the truck's original wheel setup and intended stance. If a more authentic presentation matters, confirm the sub-model, inspect the wheels currently on the truck, and use model-specific photos or build documentation to decide whether to preserve that look or move toward a different visual style.
How does tire construction affect the appearance of a restored 2009 Chevrolet Trucks Silverado 1500 LT?
On this 2009 Chevrolet Trucks Silverado 1500 LT, the primary fitments are radial tires, so the truck's expected appearance is already tied to modern radial proportions. Construction is not a bias-ply-versus-radial restoration question here; the more visible differences come from tire size, wheel diameter, sidewall treatment, and the tread character of the tire selected.
That makes size discipline especially important on a restoration-minded truck. Staying with the correct 17-inch, 18-inch, or 20-inch fitment usually does more for appearance consistency than changing to a different package size, and an RWL all-terrain tire will project a noticeably different look than a plainer street-oriented sidewall.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Chevrolet Trucks Silverado 1500 LT?
Yes. Modifications such as aftermarket wheels, altered offset, suspension lifts, lowering changes, or body adjustments can affect tire fitment on a 2009 Chevrolet Trucks Silverado 1500 LT even when the tire size seems close to stock. That matters even more on a truck like this one because several factory wheel diameters and tire sizes already exist within the same LT model range.
A replacement should be checked against the truck's actual wheel diameter, wheel width, and available clearance at steering and suspension travel. Trucks that have been changed from their original setup should be measured carefully before choosing a tire, since the correct factory size for one LT package may not suit a modified example.
What should I inspect before driving a 2009 Chevrolet Trucks Silverado 1500 LT on new tires?
Before road use, inspect the wheel diameter and tire size for a correct match, then check inflation, bead seating, sidewall condition, tread condition, and valve stems. On a 2009 Chevrolet Trucks Silverado 1500 LT, it also makes sense to confirm that the tire chosen matches the truck's exact sub-model and wheel package so the setup is consistent from the start.
A short clearance check is also worthwhile before a normal driving routine begins. Turn the steering from lock to lock, look for contact at the fenders and suspension, and recheck pressure after initial use so any mounting or slow-loss issue is caught early rather than after the truck is back in regular service.
How often should tires on a 2009 Chevrolet Trucks Silverado 1500 LT be inspected?
Tires on a 2009 Chevrolet Trucks Silverado 1500 LT should be inspected regularly, not just when tread looks low. A visual check for cracking, cuts, bulges, uneven wear, and air loss is a sensible routine, especially on a truck that may alternate between daily driving, towing duty, and longer periods of sitting.
Frequent inspections help catch problems that size alone will not reveal. It is also smart to keep an eye on wear pattern changes, since they can point to alignment, suspension, or inflation issues that affect how the tire works on the truck's particular 17-inch, 18-inch, or 20-inch setup.
