The 2008 Chevrolet Trucks Silverado 1500 LT sits in the era when half-ton pickups were expected to handle daily driving, towing, and weekend work without giving up comfort. Silverado buyers often ended up with very different wheel-and-tire combinations depending on package and wheel choice, so tire selection on this truck starts with the exact setup already on it. This Silverado 1500 LT uses radial tire fitments in 17-, 18-, and 20-inch sizes, with sub-model variation that matters. Available choices here focus on truck-ready all-terrain radials in select 17-inch sizes, including raised white letter styling. The key step is matching the truck's sub-model and wheel diameter before comparing load capacity, rim-width compatibility, and intended use.
Which Tire Size Is Right for The 2008 Chevrolet Trucks Silverado 1500 LT
Four primary tire sizes apply to the 2008 Chevrolet Trucks Silverado 1500 LT, and they vary by sub-model and wheel package rather than by a single universal fitment. The first step is confirming the exact truck configuration and wheel diameter, since this LT can use 17-inch, 18-inch, or 20-inch rims. Once that is settled, the decision shifts to the correct metric radial size, load level, and tread style for how the truck is actually used.
275/55R20 is a metric radial size in which 275 is the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 20 identifies the rim diameter in inches. On the 2008 Chevrolet Trucks Silverado 1500 LT, this size belongs with the 20-inch wheel setup rather than the 17- or 18-inch configurations used elsewhere in the lineup. Its role is to match trucks equipped with the larger wheel package. This is the size to evaluate only after confirming the truck already uses 20-inch wheels and has the clearance and wheel width appropriate to that setup.
245/70R17 is a metric radial size that uses a 245-millimeter nominal section width, a 70-series profile, and a 17-inch rim. For the 2008 Chevrolet Trucks Silverado 1500 LT, it is one of the 17-inch fitments used on certain 4x2 and 4x4 configurations, so it should not be treated as universal across every LT variant. In available product choices, this size appears in a BFGoodrich All-Terrain T/A KO2 with raised white letters and an all-terrain truck-oriented character. It is a useful size to consider when the truck already wears 17-inch wheels and the goal is to stay with the narrower of the covered 17-inch options.
Fit(s): 4x2, 4x4, w/Max Trailer Pkg., and w/Z71 Pkg.
Construction: Radial|Rim: 17 in
265/70R17 is a metric radial size with a 265-millimeter nominal section width, a 70-series profile, and a 17-inch rim diameter. Within the 2008 Chevrolet Trucks Silverado 1500 LT range, it appears across several sub-models, making it the broadest 17-inch fitment in this group, but it still depends on the specific truck and wheel setup. Available products in this size come from BFGoodrich in the All-Terrain T/A KO2 series with raised white letter styling and more than one load specification. This size deserves close attention when the truck has 17-inch wheels and the owner wants to compare load capacity and intended use within the same basic fitment.
265/65R18 is a metric radial size where 265 is the nominal width in millimeters, 65 is the aspect ratio, and 18 is the rim diameter in inches. On the 2008 Chevrolet Trucks Silverado 1500 LT, this size is tied to certain package-equipped trucks rather than the standard 17-inch or optional 20-inch combinations. Its practical importance is straightforward: it belongs with an 18-inch wheel configuration and should be judged against that exact wheel and truck setup. Buyers looking at this size should confirm the package and wheel diameter first, then compare the overall tire stance and use expectations against the truck's actual configuration.
2008 Chevrolet Trucks Silverado 1500 LT Sub-Model Tires
Sub-model fitment matters on the 2008 Chevrolet Trucks Silverado 1500 LT because tire size changes with wheel option and package. Confirming whether the truck is a 4x2, 4x4, Z71-equipped model, Max Trailer Package truck, or 20-inch option setup is the quickest way to narrow the correct tire size.

2008 Chevrolet Trucks Silverado 1500 LT (20 Inch Option)
The 20 Inch Option uses the 275/55R20 radial fitment, which puts this truck on a different wheel diameter than the 17-inch and 18-inch LT variations. Tire selection starts with confirming the truck still has its 20-inch wheels before comparing any replacement by size, wheel compatibility, and intended road use.
The 4x2 version can use either 245/70R17 or 265/70R17 radial tires, so size confirmation matters even within the same drivetrain layout. The practical choice is to verify the wheel-and-tire combination already on the truck, then compare load rating, rim-width suitability, and tread style within the correct 17-inch fitment.
The 4x4 version also uses 17-inch radial fitments, with either 245/70R17 or 265/70R17 depending on the exact setup. That means the right replacement starts with confirming which 17-inch size is on the truck now, then choosing a tire that matches the wheel and the truck's work, towing, or mixed-use role.
2008 Chevrolet Trucks Silverado 1500 LT w/Max Trailer Pkg.
The Max Trailer Package truck can use either 265/70R17 or 275/55R20, so wheel diameter is especially important before any tire is selected. This sub-model benefits from checking both the current wheel size and the tire's load specification, since towing-oriented use often makes capacity and compatibility more important than appearance alone.
2008 Chevrolet Trucks Silverado 1500 LT w/Z71 Pkg.
The Z71 Package version can use 265/65R18 or 265/70R17 radial tires, which means the package name alone does not settle the replacement size. The safest path is confirming whether the truck is on 18-inch or 17-inch wheels first, then choosing the tire that matches that setup and the truck's intended 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.

Tire Size & Fitment
What tire size fits a 2008 Chevrolet Trucks Silverado 1500 LT?
The 2008 Chevrolet Trucks Silverado 1500 LT uses four primary tire sizes: 275/55R20, 245/70R17, 265/70R17, and 265/65R18. All of these are radial fitments, and the correct one depends on the truck's sub-model, package, and wheel setup rather than one universal size for every LT.
The most important check is the wheel diameter already on the truck. A Silverado LT with 20-inch wheels needs a different tire than one equipped with 17-inch or 18-inch wheels, and some sub-models can use more than one size. Reading the current sidewall and confirming the exact sub-model will narrow the replacement choice much faster than shopping by model name alone.
What size rim does a 2008 Chevrolet Trucks Silverado 1500 LT use?
A 2008 Chevrolet Trucks Silverado 1500 LT can use 17-inch, 18-inch, or 20-inch rims depending on the specific configuration. The 245/70R17 and 265/70R17 sizes belong to 17-inch wheels, 265/65R18 belongs to an 18-inch wheel, and 275/55R20 belongs to a 20-inch wheel.
Rim diameter should be confirmed before anything else because the tire size must match it exactly. A 17-inch tire cannot be mounted on an 18-inch or 20-inch wheel, even if the truck is the same year and trim. Checking the wheel size first also helps separate package-related fitments such as Z71, Max Trailer Package, and the 20 Inch Option.
Why does the 2008 Chevrolet Trucks Silverado 1500 LT have more than one tire size?
More than one tire size appears on the 2008 Chevrolet Trucks Silverado 1500 LT because this trim was offered with different wheel diameters and package-specific setups. The 4x2, 4x4, Z71, Max Trailer Package, and 20 Inch Option versions do not all use the same wheel-and-tire combination.
That means replacement tires should be chosen by the truck's exact configuration instead of by trim name alone. Two Silverado 1500 LT trucks parked side by side may both be correct while wearing different sizes. Checking the current sidewall, wheel diameter, and any package equipment keeps the search focused on the fitment that matches the truck as it sits today.
Choosing the Right Tire
What should I consider when choosing a tire for a 2008 Chevrolet Trucks Silverado 1500 LT?
Start with the exact size and wheel diameter the truck uses, since the 2008 Chevrolet Trucks Silverado 1500 LT can take several different radial fitments. After that, compare the tire's intended use, construction details, rim-width compatibility, and load capacity so the replacement matches how the truck is actually driven or worked.
A truck used for light daily driving may be evaluated differently than one used for hauling or towing. The available 17-inch all-terrain choices also show that size alone is not the whole story, because two tires in the same basic fitment can carry different loads. Matching the tire to the truck's setup and use is more important than choosing by appearance alone.
What sidewall styles are available for 2008 Chevrolet Trucks Silverado 1500 LT tires?
Among the available products for this Silverado 1500 LT, the covered 17-inch BFGoodrich options use RWL sidewalls. That stands for raised white letter styling, a look that gives an all-terrain truck tire a more traditional performance-truck presentation than a plain blackwall sidewall.
Sidewall style matters mostly for appearance, but it can still help narrow the right tire when two products share the same basic size. Raised white letters tend to suit owners who want a more visible, period-truck look, while other buyers may focus more on size, rim-width range, and load specification. The important point is to keep appearance as a secondary decision after fitment.
What brands offer tires for the 2008 Chevrolet Trucks Silverado 1500 LT?
The available products in these Silverado 1500 LT fitments are from BFGoodrich. The current covered selections are in the All-Terrain T/A KO2 series for 245/70R17 and 265/70R17, giving the truck an all-terrain radial option within those 17-inch sizes.
Brand is only one part of the decision. Even within the same BFGoodrich series, the 265/70R17 options differ in load specification, so buyers still need to compare the exact tire rather than stop at the brand name. Once the truck's proper size is confirmed, it makes sense to compare series character, sidewall style, rim-width range, and capacity within that fitment.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Chevrolet Trucks Silverado 1500 LT?
A period-style choice for a 2008 Chevrolet Trucks Silverado 1500 LT starts with keeping the truck in its correct original wheel diameter and primary tire size for the exact sub-model. On this generation of pickup, that means matching the truck to its 17-inch, 18-inch, or 20-inch radial fitment before thinking about tread style or sidewall presentation.
Because this is a modern truck by Coker-era standards, appearance usually comes down to preserving the truck's proper stance and wheel-and-tire relationship rather than chasing a vintage bias-ply look. Owners focused on originality should compare the truck's current setup with factory reference material or model-specific Chevrolet sources, then choose a tire that supports that visual goal without straying from the correct size.
How does tire construction affect the appearance of a restored 2008 Chevrolet Trucks Silverado 1500 LT?
Construction is straightforward on the 2008 Chevrolet Trucks Silverado 1500 LT because the primary fitments here are radial tires. That keeps the visual decision focused less on bias-ply versus radial shape and more on maintaining the correct wheel diameter, sidewall height, and overall stance for the truck's particular package.
Appearance can still change noticeably if the truck is moved to the wrong size or wheel diameter. A Silverado restored with the proper 17-, 18-, or 20-inch setup will generally look more convincing than one wearing an arbitrary substitute, even if the tire itself is high quality. Raised white letter sidewalls can also influence the presentation when that look suits the truck's intended style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Chevrolet Trucks Silverado 1500 LT?
Yes, modifications can change tire fitment on a 2008 Chevrolet Trucks Silverado 1500 LT even when the nominal tire size sounds correct. Aftermarket wheels, suspension lifts, lowering kits, wheel-offset changes, and body modifications can all alter clearance, steering travel, and the rim-width relationship that the tire is expected to work with.
A truck that has been changed from stock should be checked as it actually sits, not only by the factory size associated with the sub-model. Wheel diameter still has to match exactly, but width and clearance matter too. Looking at inside clearance, fender room, and full-lock steering movement helps prevent rubbing or compatibility issues after the new tires are mounted.
What should I inspect before driving a 2008 Chevrolet Trucks Silverado 1500 LT on new tires?
Before regular road use, inspect tire pressure, bead seating, valve stems, lug-nut torque, and the basic condition of the wheels. It also makes sense to look for sidewall damage, tread irregularities, or any sign that the mounted tire does not match the truck's intended wheel diameter and clearance requirements.
A short test drive followed by a second inspection is a smart habit, especially on a truck that may tow or carry heavier loads. Steering feel, clearance at full turn, and any contact under suspension movement are worth checking early. Catching those issues right away helps confirm that the selected size and wheel combination are behaving properly on the Silverado.
What should I check before a longer drive in a 2008 Chevrolet Trucks Silverado 1500 LT?
Before a longer drive, make sure the 2008 Chevrolet Trucks Silverado 1500 LT is on the correct tire size for its wheel diameter and that inflation is appropriate for the tire being used. Check for uneven wear, cuts, bulges, embedded debris, and any slow air loss, especially if the truck has been parked for extended periods.
Longer trips place more importance on stability and load handling, so the tire's condition matters as much as the size itself. Trucks used for towing or cargo duty deserve an extra look at overall tire health before departure. It is also wise to inspect the spare, since a mismatched or neglected spare can become a problem when the truck is away from home.
