The 2004 Chevrolet Trucks Trailblazer sits in the era when midsize SUVs were expected to balance daily-driver comfort with genuine utility, offering truck-based durability in a more family-friendly package. That matters when choosing tires, because this Trailblazer uses two different primary radial sizes depending on sub-model: 245/70R16 or 245/65R17. Both are modern metric radial fitments, but the first decision is confirming whether the vehicle is an LS, LT, or North Face and checking the wheel diameter already on the truck. From there, the focus shifts to selecting the right radial tire for the vehicle's intended road use, stance, and wheel setup.
Which Tire Size Is Right for The 2004 Chevrolet Trucks Trailblazer
The 2004 Chevrolet Trucks Trailblazer uses two primary tire sizes, and the correct one depends on sub-model and wheel diameter. LS and LT models use 245/70R16 on a 16-inch rim, while the North Face uses 245/65R17 on a 17-inch rim. Before choosing a tire, confirm the exact sub-model and verify the wheel diameter currently on the vehicle, especially if the Trailblazer has seen wheel or trim changes over the years.
A 245/70R16 tire is a metric radial size with a 245-millimeter nominal section width, a 70-series aspect ratio, radial construction, and fitment for a 16-inch wheel. On the 2004 Chevrolet Trucks Trailblazer, this is the primary fitment for LS and LT sub-models, making it the key size to match if the vehicle retains its original 16-inch wheel setup. Available choices in this size include BFGoodrich's All-Terrain T/A KO2 with raised white letter sidewall styling. It is the size to evaluate when the goal is maintaining the proper 16-inch fitment while choosing a tire with a more truck-oriented look and use profile.
A 245/65R17 tire uses the same 245-millimeter nominal width but pairs it with a 65-series aspect ratio and a 17-inch rim diameter in radial construction. For the 2004 Chevrolet Trucks Trailblazer, this size belongs to the North Face sub-model, so it should not be assumed to apply across the rest of the lineup. BFGoodrich offers this size in the All-Terrain T/A KO2 with a raised white letter sidewall, giving it a distinctly utility-focused appearance. It is the right size to assess when the truck is already on 17-inch wheels and the objective is preserving that wheel-and-tire combination correctly.
Sub-model fitment matters on the 2004 Chevrolet Trucks Trailblazer because tire size changes with trim. LS and LT share the same size, while the North Face moves to a different size on a different wheel diameter, so identifying the exact sub-model is the first step before comparing tires.

2004 Chevrolet Trucks Trailblazer LS
The 2004 Chevrolet Trucks Trailblazer LS uses the 245/70R16 radial tire size. Tire selection for an LS centers on confirming the existing 16-inch wheels, then choosing among available radial options that suit how the SUV is driven and the look you want on the vehicle.
The 2004 Chevrolet Trucks Trailblazer LT also uses the 245/70R16 radial tire size. That keeps fitment straightforward if the truck still wears its 16-inch wheel setup, and the buying decision becomes more about tire style, intended use, and wheel compatibility than size confusion.
The 2004 Chevrolet Trucks Trailblazer North Face uses the 245/65R17 radial tire size rather than the 16-inch fitment seen on LS and LT models. Tire selection here starts with confirming the 17-inch wheels and then choosing a radial tire that matches the vehicle's current setup and clearance.
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 2004 Chevrolet Trucks Trailblazer Tires for Sale
Available Trailblazer tire choices center on BFGoodrich All-Terrain T/A KO2 radials in both primary sizes. The comparison is straightforward: 16-inch or 17-inch fitment, raised white letter sidewalls, and the rim-width and load specifications that match each size.
Trailblazer owners usually need to sort out the exact tire size by sub-model and wheel diameter first. From there, the important questions involve radial fitment, sidewall presentation, product selection, and the checks to make before regular road use.
Tire Size & Fitment
What tire size fits a 2004 Chevrolet Trucks Trailblazer?
The 2004 Chevrolet Trucks Trailblazer uses either 245/70R16 or 245/65R17, depending on sub-model. LS and LT models use 245/70R16, while the North Face uses 245/65R17. Both are radial tire sizes, but they mount on different wheel diameters, so they are not interchangeable as primary fitments without changing wheels.
The most important first step is identifying the exact Trailblazer sub-model and confirming whether the truck has 16-inch or 17-inch wheels on it now. On an older SUV, wheel swaps are common, so checking the tire sidewall and the actual wheel diameter helps prevent ordering the right size for the wrong setup.
What size rim does a 2004 Chevrolet Trucks Trailblazer use?
A 2004 Chevrolet Trucks Trailblazer uses either a 16-inch or 17-inch rim, depending on sub-model. The 245/70R16 fitment uses a 16-inch wheel, and the 245/65R17 fitment uses a 17-inch wheel. Both sizes are metric radial fitments, but the wheel diameter must match the tire exactly.
Wheel diameter is the first fitment checkpoint because a 16-inch tire cannot be mounted on a 17-inch rim, and vice versa. It also helps to confirm wheel width before choosing among available tires, especially if the Trailblazer has aftermarket wheels or has been changed from its original trim-specific wheel package.
Do all 2004 Chevrolet Trucks Trailblazer sub-models use the same tire size?
No, not all 2004 Chevrolet Trucks Trailblazer sub-models use the same tire size. The LS and LT share the 245/70R16 size, while the North Face uses 245/65R17. That means the covered lineup has two distinct primary fitments, each tied to a different wheel diameter.
This difference matters because the correct tire choice depends on more than just the model name. A North Face should be checked for its 17-inch wheel setup, while LS and LT owners should verify the 16-inch arrangement. If the truck has replacement wheels, use the actual wheel and current tire markings as the final reference point.
Choosing the Right Tire
What should I consider when choosing a tire for a 2004 Chevrolet Trucks Trailblazer?
Start with the correct size for the exact sub-model: 245/70R16 for LS and LT, or 245/65R17 for North Face. From there, look at construction, rim-width compatibility, load capacity, and how the tire's character matches the way the Trailblazer is used on pavement, gravel, or mixed driving.
The available BFGoodrich All-Terrain T/A KO2 options give this Trailblazer a more rugged, truck-style presentation, so appearance may matter along with fitment. It is also worth checking whether the SUV still has its original wheel diameter, since choosing the correct tire size begins with matching the current wheel setup rather than assuming all trims use the same package.
What sidewall styles are available for 2004 Chevrolet Trucks Trailblazer tires?
The available Trailblazer products in these two primary sizes use an RWL sidewall style, meaning raised white letters. That treatment gives the tire a more assertive, utility-oriented look than a plain blackwall and can change the visual character of the SUV even when the size remains factory-style for the sub-model.
Sidewall style should still be considered alongside the correct size, wheel diameter, and intended use. Raised white letters tend to stand out more on a truck or SUV, so some owners choose them for a traditional off-road-inspired appearance, while others may care more about maintaining the proper sub-model fitment and rim compatibility first.
What brands offer tires for the 2004 Chevrolet Trucks Trailblazer?
BFGoodrich is the available brand across the 245/70R16 and 245/65R17 Trailblazer fitments here. Both sizes are offered in the All-Terrain T/A KO2 series, giving the 2004 Chevrolet Trucks Trailblazer a consistent brand and tire-family choice across the two trim-specific wheel and tire combinations.
Since the brand choice is straightforward, the more useful comparison is between the two fitment sizes and their wheel requirements. Trailblazer owners should focus on confirming whether the truck uses the 16-inch LS or LT setup or the 17-inch North Face setup, then compare rim-width range, load figure, and sidewall presentation within that correct size.
Restoration & Appearance
Which tire should I choose for a period-style 2004 Chevrolet Trucks Trailblazer?
A period-style choice for a 2004 Chevrolet Trucks Trailblazer starts with keeping the correct trim-specific size and wheel diameter in place. That means 245/70R16 for LS and LT models or 245/65R17 for the North Face. Staying with the proper size preserves the truck's intended stance more faithfully than mixing trim-level fitments.
Appearance then comes down to how the available tire presents on the vehicle. The BFGoodrich All-Terrain T/A KO2 adds a more rugged look through its raised white letter sidewall and all-terrain character, so owners aiming for a stock-style appearance may want to weigh visual style as carefully as fitment before making a final selection.
Does correct tire fitment matter for a 2004 Chevrolet Trucks Trailblazer restoration?
Yes, correct tire fitment matters because the 2004 Chevrolet Trucks Trailblazer did not use one universal size across every covered sub-model. LS and LT models use 245/70R16, while the North Face uses 245/65R17. Choosing the right size helps preserve the proper wheel-to-tire relationship for the specific version being restored.
Even on a newer collector-era SUV, the wrong wheel diameter or trim-level fitment can alter the vehicle's stance and visual balance. Owners working toward an appearance-focused restoration should confirm the sub-model first, then verify the current wheels on the truck so the tire choice supports the intended presentation instead of working against it.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Chevrolet Trucks Trailblazer?
Yes, modifications can affect tire fitment on a 2004 Chevrolet Trucks Trailblazer. Aftermarket wheels, suspension changes, altered ride height, or non-original trim swaps can all change the space available around the tire and may also change the wheel diameter or width compared with the original LS, LT, or North Face setup.
A modified Trailblazer should be checked at the wheel before any tire is chosen. Verify the actual rim diameter, measure wheel width if necessary, and inspect clearance at the fender, steering, and suspension areas. Those checks matter even when the tire size sounds familiar, because the current hardware on the truck is what ultimately governs fitment.
What should I inspect before driving a 2004 Chevrolet Trucks Trailblazer on new tires?
Before driving a 2004 Chevrolet Trucks Trailblazer on new tires, inspect the wheel condition, confirm the tire size matches the sub-model and wheel diameter, and check inflation pressure carefully. It is also wise to look over the valve stems, lug hardware, and general wheel seating so the tire starts service on a sound foundation.
A short road test should follow with attention to rubbing, steering feel, and any sign of vibration. Trailblazers that have had wheel changes, suspension work, or long periods of storage deserve an extra look at alignment condition and clearance, since a new tire can reveal problems that were already present in the truck's setup.
How should tires on a 2004 Chevrolet Trucks Trailblazer be maintained?
Tires on a 2004 Chevrolet Trucks Trailblazer should be maintained with regular pressure checks, visual inspections for cuts or sidewall damage, and routine monitoring for uneven wear. Since these are SUV fitments, keeping the tires matched to the proper wheel size and watching for air loss is especially important in everyday use.
Low-use vehicles still need attention, because age and storage can affect a tire even when tread looks acceptable. A Trailblazer that sits for long periods should have its tires inspected for cracking, flat spotting, and general condition before longer trips, and the wheel-and-tire setup should be rechecked any time suspension or wheel changes are made.
