The 2005 Chevrolet Trucks Silverado 1500 LT sits in the era when full-size pickups were expected to handle daily driving, work duty, and weekend use without giving up comfort. Buyers still gravitate to these trucks for their straightforward capability and broad aftermarket support, but tire choice remains a fitment-first decision. This Silverado 1500 LT uses 17-inch radial tire fitments, with 245/70R17 and 265/70R17 both appearing depending on configuration. That means the real choice is confirming whether the truck is a 4x2 or 4x4 and then comparing the available all-terrain options within the correct size. Wheel setup, load needs, and intended use should guide the final decision.
Which Tire Size Is Right for The 2005 Chevrolet Trucks Silverado 1500 LT
Two primary tire sizes apply to the 2005 Chevrolet Trucks Silverado 1500 LT, and both are radial tires built for 17-inch wheels. The first step is identifying the exact sub-model, because the 4x4 uses 265/70R17 while the 4x2 may use either 245/70R17 or 265/70R17. Once that is confirmed, the decision shifts to load specification, wheel-width compatibility, and how the truck is actually used.
245/70R17 is a metric radial size in which 245 identifies the nominal section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On this Silverado 1500 LT, it is one of the 17-inch radial fitments used on certain 4x2 configurations. Available choices in this size center on BFGoodrich's All-Terrain T/A KO2 with raised white letter sidewalls and a rim-width range of 6.5 to 8.0 inches. This size is worth evaluating when the truck already has the matching wheel setup and you want to stay with the narrower of the two listed fitments.
265/70R17 is a metric radial size where 265 represents nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 17 identifies the wheel diameter. For the 2005 Silverado 1500 LT, this size is the sole fitment on the 4x4 and also appears on some 4x2 trucks. BFGoodrich offers this size in the All-Terrain T/A KO2 with raised white letter sidewalls, and the available versions differ in load specification while sharing a 7.0 to 9.0 inch rim-width range. It is the size to examine closely when wheel width, truck configuration, and intended duty point toward the broader listed fitment.
2005 Chevrolet Trucks Silverado 1500 LT Sub-Model Tires
Sub-model fitment matters on the 2005 Chevrolet Trucks Silverado 1500 LT because tire size is not completely uniform across the range. The 4x4 is tied to one size, while the 4x2 can appear with either listed fitment, so confirming the exact truck configuration is the key first step.

2005 Chevrolet Trucks Silverado 1500 LT 4x2
The Silverado 1500 LT 4x2 can use either 245/70R17 or 265/70R17, both in radial construction on 17-inch wheels. That makes wheel width and the truck's current setup especially important before choosing between the available all-terrain options.
The Silverado 1500 LT 4x4 uses 265/70R17 radial tires on 17-inch wheels. Tire selection here is more straightforward, with the main comparison centered on the available KO2 load specifications and making sure the wheel matches the required rim-width range.
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 2005 Chevrolet Trucks Silverado 1500 LT Tires for Sale
Available 17-inch choices for the 2005 Chevrolet Trucks Silverado 1500 LT focus on BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls. The main points to compare are size, load specification, and rim-width compatibility within the truck's 245/70R17 or 265/70R17 fitment.
Common questions for the 2005 Chevrolet Trucks Silverado 1500 LT usually come down to the correct tire size by sub-model, 17-inch wheel fitment, KO2 selection details, and the checks worth making before putting a truck back into regular road use.
Tire Size & Fitment
What tire size fits a 2005 Chevrolet Trucks Silverado 1500 LT?
The 2005 Chevrolet Trucks Silverado 1500 LT uses two primary tire sizes: 245/70R17 and 265/70R17. Both are radial tires built for 17-inch wheels, but they do not apply the same way across every configuration. The 4x4 uses 265/70R17, while the 4x2 may use either 245/70R17 or 265/70R17.
The practical step is confirming the exact sub-model and the wheel setup already on the truck before choosing a tire. A Silverado that has been changed over to different wheels or suspension parts should be checked carefully, because the correct page-level fitment still needs to match the actual wheel width and available clearance on that truck.
What size rim does a 2005 Chevrolet Trucks Silverado 1500 LT use?
The listed tire fitments for the 2005 Chevrolet Trucks Silverado 1500 LT are built around a 17-inch rim diameter. Both 245/70R17 and 265/70R17 use that same 17-inch wheel diameter, so the rim diameter itself stays consistent even though the truck can carry more than one tire size.
Rim diameter is only part of the picture, so wheel width still needs attention when comparing tires. The available 245/70R17 option calls for a 6.5 to 8.0 inch rim width, while the 265/70R17 options use a 7.0 to 9.0 inch range, making it important to match the tire to the wheel actually on the truck.
Why does the 2005 Chevrolet Trucks Silverado 1500 LT have more than one tire size?
More than one tire size appears because fitment varies by sub-model within the 2005 Chevrolet Trucks Silverado 1500 LT range. The 4x4 uses 265/70R17, while the 4x2 can be equipped with either 245/70R17 or 265/70R17. Both sizes share the same 17-inch rim diameter and radial construction.
That means the correct choice starts with identifying whether the truck is a 4x2 or 4x4 and then checking the current wheels. Some trucks no longer wear their original wheel-and-tire combination, so selecting by the truck's actual setup helps avoid choosing a tire that matches the model range in general but not the specific vehicle in front of you.
Choosing the Right Tire
What should I consider when choosing a tire for a 2005 Chevrolet Trucks Silverado 1500 LT?
Start with the correct size for the truck's configuration: 245/70R17 or 265/70R17 on a 17-inch wheel. From there, compare construction, load specification, and wheel-width compatibility. The available options here are radial BFGoodrich All-Terrain T/A KO2 tires, so the main differences are size and the load version offered within that size.
Use the truck's intended duty to narrow the choice. A lightly used street truck, a work-oriented pickup, and a truck that sees more cargo or trailer weight can point toward different load needs even within the same size. Checking the actual wheel width and confirming the truck's current stance helps keep the selection grounded in fitment rather than appearance alone.
What sidewall styles are available for 2005 Chevrolet Trucks Silverado 1500 LT tires?
The available products for this Silverado 1500 LT use RWL sidewalls, which is the common raised white letter presentation. That gives the truck a more traditional all-terrain look than a plain blackwall and is consistent across the currently available 245/70R17 and 265/70R17 options.
Sidewall style mainly affects appearance, but it still belongs in the buying decision because a Silverado can lean more toward stock daily-driver presentation or a more rugged, off-road-inspired look. Once the correct tire size is confirmed, the sidewall treatment becomes part of matching the tire to the truck's overall character without losing sight of size and wheel compatibility.
How do I choose between the available 265/70R17 tires for a 2005 Chevrolet Trucks Silverado 1500 LT?
The available 265/70R17 choices are both BFGoodrich All-Terrain T/A KO2 radials with raised white letter sidewalls, so the biggest difference is load specification. One version is rated at 2,470 lbs @ 50 psi, while another is rated at 3,195 lbs @ 80 psi. Both use a 17-inch rim and call for a 7.0 to 9.0 inch wheel-width range.
That makes the real comparison less about style and more about how the truck is used. A Silverado that carries heavier loads or needs a higher-capacity tire should be evaluated differently from one used mostly for lighter-duty driving. Matching the tire's load and pressure specification to the truck's actual service is more important than choosing by size alone.
Restoration & Appearance
Which tire should I choose for a period-style 2005 Chevrolet Trucks Silverado 1500 LT?
A period-style choice starts with the size that belongs on the truck's exact configuration, either 245/70R17 or 265/70R17, both in radial construction on 17-inch wheels. Within those fitments, the available BFGoodrich All-Terrain T/A KO2 options give the Silverado a distinctly truck-oriented look that suits the era well.
Appearance should still follow fitment. The 4x4 points directly to 265/70R17, while a 4x2 may use either listed size depending on setup, so verifying the wheel and the truck's current configuration matters before focusing on style. Buyers chasing exact originality should compare the truck against build records, original literature, or marque-specific references.
How does tire construction affect the appearance of a restored 2005 Chevrolet Trucks Silverado 1500 LT?
Construction is straightforward here because the listed fitments for the 2005 Chevrolet Trucks Silverado 1500 LT are radial. That means the appearance decision is shaped less by bias-ply-versus-radial differences and more by choosing the correct size, overall stance, and sidewall treatment within the available radial options.
Raised white letter sidewalls give the truck a stronger all-terrain visual presence than a plain sidewall would, which can matter on an early-2000s pickup restoration or cleanup project. Even so, tire appearance should support the truck's intended presentation without forcing a size that does not match the vehicle's wheel width or sub-model fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2005 Chevrolet Trucks Silverado 1500 LT?
Yes, modifications can change how either 245/70R17 or 265/70R17 fits on a 2005 Chevrolet Trucks Silverado 1500 LT. Aftermarket wheels, altered wheel width, suspension lifts or lowering, and body or steering changes can all affect clearance even when the tire size itself is one of the correct fitments for the model range.
A truck that has been changed from its original setup should be checked at the wheels and on the vehicle, not just by model name. Looking at wheel width, turning clearance, and space at the fenders helps confirm that the chosen size works with the truck as it sits today rather than how it left the factory.
What should I inspect before driving a 2005 Chevrolet Trucks Silverado 1500 LT on new tires?
Inspect the wheels, valve stems, and the truck's general suspension and steering condition before putting new tires into service. Tire pressure should be set appropriately for the selected tire, and the wheel itself should match the size and rim-width requirement. It also helps to look for uneven wear patterns on the old tires that might point to alignment or front-end issues.
A short road check after installation is worthwhile to confirm there is no rubbing at full steering lock or over suspension movement. On a truck used for hauling, towing, or rougher roads, rechecking inflation and looking over the sidewalls after the first drives can catch setup problems early before they turn into accelerated wear.
How often should tires on a 2005 Chevrolet Trucks Silverado 1500 LT be inspected?
Tires on a 2005 Chevrolet Trucks Silverado 1500 LT should be inspected regularly, not only when wear becomes obvious. Pressure, tread condition, cuts, bulges, cracking, and signs of air loss all deserve attention, especially on a truck that may alternate between daily use and long periods of sitting.
A quick visual check before longer drives is a good habit, and a closer inspection becomes more important after load-carrying, rough-road use, or seasonal storage. Trucks that do not accumulate many miles can still age their tires, so time and condition matter just as much as tread depth when deciding whether the set is still roadworthy.
