The 2004 Dodge Trucks Ram 1500 belongs to the early third-generation Ram lineup, a period when Dodge gave its full-size pickup a bolder look and a wider spread of trims, cab styles, and street-to-work-truck personalities. That matters when choosing tires, because this Ram 1500 uses several different radial sizes depending on the exact sub-model, with 17-inch, 20-inch, and 22-inch wheel fitments all in the mix. Some versions stay in more traditional truck-oriented 17-inch metric sizes, while others move to larger-diameter wheel packages. The right choice starts with identifying the exact trim and wheel setup, then matching the tire's intended look and use to the truck.
Which Tire Size Is Right for The 2004 Dodge Trucks Ram 1500
The 2004 Dodge Trucks Ram 1500 uses six primary tire sizes, and the correct one depends on the exact sub-model and wheel package. Since this truck appears with 17-inch, 20-inch, and 22-inch rim diameters, the first step is confirming the actual wheel diameter on the vehicle, then matching that to the correct metric radial size for the trim and intended use.
265/70R17 is a metric radial size in which 265 identifies the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 17 is the wheel diameter in inches. On the 2004 Dodge Trucks Ram 1500, this size is one of the core 17-inch fitments used across several Laramie and SLT configurations. Available products in this size center on BFGoodrich's All-Terrain T/A KO2 with raised white letter sidewalls and different load-capacity versions. It is the right size to evaluate when the truck retains the 17-inch setup used on those specific trims.
275/70R17 follows the same metric radial format, with a 275-millimeter nominal width, a 70-series profile, radial construction, and a 17-inch rim diameter. This size appears on certain 4x4 regular cab versions of the 2004 Dodge Trucks Ram 1500, making it a fitment that should not be assumed across the whole model range. Its dimensions place it in the truck-oriented side of the Ram lineup rather than the larger-wheel street packages. This is the size to verify when a 4x4 regular cab truck has the corresponding 17-inch wheel setup and needs that wider primary fitment.
275/55R20 is a metric radial tire with a 275-millimeter nominal width, a 55-series aspect ratio, and a 20-inch wheel diameter. On the 2004 Dodge Trucks Ram 1500, it is tied to the SLT w/Image Group and represents one of the larger-wheel factory-style fitment directions within this model range. Compared with the 17-inch truck sizes, this code reflects a different wheel package and a lower-profile sizing approach. It should be considered only after confirming that the truck actually uses the 20-inch wheel arrangement associated with that sub-model.
275/60R20 uses the modern metric radial system, combining a 275-millimeter nominal section width with a 60-series profile and a 20-inch rim diameter. This size also appears on the 2004 Dodge Trucks Ram 1500 SLT w/Image Group, so the buyer decision is not just trim level but the truck's exact wheel-and-tire setup. It stays in the same 20-inch wheel family as 275/55R20 while representing a different primary size choice. This is the fitment to examine when a Ram with the Image Group package needs the taller of the two documented 20-inch tire sizes.
305/40R22 is a metric radial size with a 305-millimeter nominal width, a 40-series profile, and a 22-inch wheel diameter. On the 2004 Dodge Trucks Ram 1500, this size belongs to the SRT-10 and stands apart from the rest of the lineup because it uses a much larger wheel diameter and a distinctly performance-oriented sizing profile. That makes wheel confirmation especially important before any replacement decision is made. This is the correct size to pursue only when the truck is the SRT-10 with its 22-inch configuration rather than a standard Ram 1500 trim.
245/70R17 is a metric radial tire size where 245 gives the nominal width in millimeters, 70 is the aspect ratio, R marks radial construction, and 17 is the rim diameter in inches. On the 2004 Dodge Trucks Ram 1500, this size is used on the ST and represents a narrower 17-inch fitment than some other trims in the range. Available products include BFGoodrich All-Terrain T/A KO2 in raised white letter form, bringing a more traditional truck sidewall presentation. It is the size to match when an ST model keeps its original-type 17-inch wheel diameter and corresponding tire footprint.
Fitment varies across the 2004 Dodge Trucks Ram 1500 lineup, so the exact sub-model matters before choosing a tire. Some trims share the same 17-inch radial size, while others move to alternate 17-inch, 20-inch, or 22-inch wheel packages that change the tire decision completely.

2004 Dodge Trucks Ram 1500 Laramie 4x2 Reg. Cab
The Laramie 4x2 Reg. Cab uses a straightforward 17-inch radial fitment, making size identification simpler than on some other Ram 1500 variants. Tire selection then becomes a matter of matching the correct 17-inch size to the truck's actual wheel setup and intended use.
The Laramie 4x4 Reg. Cab is one of the Ram 1500 sub-models that can use more than one primary tire size, so confirming the exact wheel-and-tire setup is essential. That means checking the truck itself before replacement rather than assuming every 4x4 regular cab uses the same 17-inch tire.
The Laramie Quad Cab stays with a 17-inch radial fitment, which keeps the tire search focused once the sub-model is confirmed. Buyers can then concentrate on selecting the right tire within that size instead of sorting through the larger-wheel Ram packages.
The SLT 4x2 Reg. Cab uses a 17-inch radial tire setup shared with several other non-specialty Ram 1500 configurations. Once that trim is verified, the next step is choosing a tire that matches the correct size and the truck's day-to-day work, road, or mixed-use role.
The SLT 4x4 Reg. Cab can appear with two primary 17-inch tire sizes, so replacement starts with confirming which one is actually on the truck. That check matters more than trim name alone, since the wrong width and overall sizing choice can send the buyer toward the wrong product category.
The SLT Quad Cab uses a 17-inch radial fitment that keeps tire selection relatively direct once the truck is correctly identified. With size settled, attention can shift to product characteristics such as load version, rim-width compatibility, and sidewall presentation.
The SLT w/Image Group moves into the 20-inch wheel category and can use two different primary tire sizes within that setup. That makes wheel confirmation especially important, because a 20-inch Ram package requires a different tire path than the more common 17-inch trucks.
The SRT-10 uses a distinct 22-inch radial tire size that sets it apart from the rest of the 2004 Ram 1500 range. Tire selection for this model starts with preserving that specific large-diameter wheel fitment rather than treating it like a standard work-truck configuration.
The ST uses its own 17-inch radial tire size, separate from some of the wider 17-inch fitments elsewhere in the Ram 1500 lineup. That makes it important to confirm the ST setup specifically before comparing products, even when the wheel diameter appears similar.
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 Dodge Trucks Ram 1500 Tires for Sale
Available product choices for the 2004 Dodge Trucks Ram 1500 currently center on 17-inch BFGoodrich All-Terrain T/A KO2 tires in RWL form. Within those sizes, the comparison points are load-capacity version, rim-width compatibility, and matching the product to the truck's exact 17-inch fitment.
Owners of a 2004 Dodge Trucks Ram 1500 usually need to sort out the exact tire size by sub-model and wheel diameter first. The questions below focus on fitment, radial sizing, product choice, appearance, and the checks worth making before regular road use.
Tire Size & Fitment
What tire size fits a 2004 Dodge Trucks Ram 1500?
The 2004 Dodge Trucks Ram 1500 uses several primary tire sizes: 245/70R17, 265/70R17, 275/70R17, 275/55R20, 275/60R20, and 305/40R22. All of them are radial sizes, and the correct one depends on the exact sub-model and wheel package rather than the model name alone.
The most important step is confirming the truck's actual wheel diameter first, because this Ram appears with 17-inch, 20-inch, and 22-inch setups. After that, verify the exact trim and inspect the current tire placard or existing wheel-and-tire combination so the replacement size matches the truck's specific configuration.
What size rim does a 2004 Dodge Trucks Ram 1500 use?
A 2004 Dodge Trucks Ram 1500 can use 17-inch, 20-inch, or 22-inch rims depending on the sub-model and tire size. The 17-inch wheel is the most common among standard trims, while certain Image Group trucks use 20-inch wheels and the SRT-10 uses a 22-inch setup.
Rim diameter should be confirmed before looking at any replacement tire, because two trucks with the same model year and name may not share the same wheel package. Checking the wheel itself and the tire sidewall is the quickest way to avoid selecting a size from the wrong Ram 1500 trim.
Why does the 2004 Dodge Trucks Ram 1500 have more than one tire size?
The 2004 Dodge Trucks Ram 1500 covers a wide range of trims and configurations, including regular cabs, quad cabs, 4x2 and 4x4 models, Image Group trucks, and the SRT-10. That spread leads to multiple tire sizes and multiple rim diameters within the same year, make, and model family.
A buyer should not choose a tire by year and model alone on this truck. The safer approach is to identify the exact sub-model, then confirm whether the truck has its original wheel package or a later wheel change, since that can shift the correct tire size even within the same trim name.
Choosing the Right Tire
What should I consider when choosing a tire for a 2004 Dodge Trucks Ram 1500?
Start with the correct primary size for the exact sub-model and wheel diameter, because the 2004 Dodge Trucks Ram 1500 spans several different radial fitments. From there, compare construction details that matter to use, such as load version, rim-width compatibility, and whether the truck needs a 17-inch, 20-inch, or 22-inch application.
Once the fitment is narrowed down, think about how the truck is actually used. A road-driven ST or SLT may need different priorities than a truck seeing heavier duty or mixed terrain, so sidewall style, product series, and load specification should be compared against the truck's setup instead of chosen by appearance alone.
What sidewall styles are available for 2004 Dodge Trucks Ram 1500 tires?
Among the currently available products for this application, raised white letter sidewalls are offered on the BFGoodrich All-Terrain T/A KO2 sizes that fit certain 17-inch Ram 1500 configurations. That gives those trucks a more traditional truck-tire appearance than a plain black sidewall presentation.
Sidewall style should still come after correct size and wheel diameter. A raised white letter tire can change the truck's visual character, but it only makes sense when the size, load version, and rim-width specification also suit the exact Ram 1500 trim and the way the truck is driven.
What brands offer tires for the 2004 Dodge Trucks Ram 1500?
Current product coverage for the documented 17-inch Ram 1500 fitments includes BFGoodrich. The available offering is centered on the All-Terrain T/A KO2 series, giving buyers a clear product family to compare within those specific sizes rather than a broad mix of unrelated tire types.
Brand alone should not make the decision on a truck with multiple possible sizes. Confirm the exact Ram 1500 trim, check the wheel diameter, and then compare the available product's load rating version, rim-width range, and sidewall treatment so the tire matches both the truck and its intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2004 Dodge Trucks Ram 1500?
A period-style choice for a 2004 Dodge Trucks Ram 1500 starts with preserving the truck's original-type size format and wheel diameter for its exact sub-model. Since this Ram uses modern metric radial sizing throughout, the most authentic-looking direction usually means staying with the correct 17-inch, 20-inch, or 22-inch radial fitment first.
Appearance choices should follow fitment, not replace it. A truck that retains its factory-era visual character generally benefits from keeping the proper tire proportions for the trim, and owners pursuing exact originality should compare sidewall presentation and wheel setup against period photos, build information, or marque-specific references.
How does tire construction affect the appearance of a restored 2004 Dodge Trucks Ram 1500?
On a 2004 Dodge Trucks Ram 1500, construction is straightforward because the primary fitments are radial rather than bias-ply. That means the appearance question is less about choosing between vintage constructions and more about keeping the correct metric radial size, profile, and wheel diameter for the truck's exact trim.
Visual character still changes when the proportions change. A 17-inch truck tire presents differently from a 20-inch Image Group setup or a 22-inch SRT-10 fitment, so a restoration-minded owner should avoid treating all Ram 1500 wheel packages as interchangeable simply because they belong to the same model year.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2004 Dodge Trucks Ram 1500?
Yes, modifications can affect tire fitment on a 2004 Dodge Trucks Ram 1500 even when the tire size sounds close to stock. Aftermarket wheels, altered wheel width, suspension changes, ride-height changes, or body modifications can all influence whether the original tire size still suits the truck's actual setup.
A modified Ram should be checked at the wheel and fender rather than by trim name alone. Steering clearance, suspension travel, and the relationship between tire width and wheel width are especially important on trucks that no longer retain their original wheels, particularly across this model's 17-inch, 20-inch, and 22-inch combinations.
What should I inspect before driving a 2004 Dodge Trucks Ram 1500 on new tires?
Before driving a 2004 Dodge Trucks Ram 1500 on new tires, inspect the wheels for damage, confirm the tire size matches the truck's actual wheel diameter, and verify that inflation is appropriate for the tire being used. It is also wise to check lug hardware, valve stems, and overall clearance at full steering lock.
Road-readiness involves more than fresh rubber. A truck that has worn suspension parts, alignment issues, or uneven previous tire wear can shorten the life of a new set quickly, so a brief inspection of shocks, steering components, and visible suspension condition helps make sure the new tires start out on a stable foundation.
How often should tires on a 2004 Dodge Trucks Ram 1500 be inspected?
Tires on a 2004 Dodge Trucks Ram 1500 should be inspected regularly, not only when replacement time arrives. A quick visual check for air loss, uneven wear, cuts, cracking, or bulges is worthwhile before routine driving, and a more thorough inspection makes sense before towing, highway travel, or longer trips.
Even a truck that is used lightly can develop age-related issues or pressure loss between drives. Consistent inspection also helps catch problems caused by alignment drift, wheel damage, or suspension wear early, which is especially useful on a Ram 1500 lineup where different trims carry very different tire widths, profiles, and wheel diameters.
