The 2005 Dodge Trucks Ram 1500 SLT sits in the modern full-size pickup era when trim, cab configuration, and option packages could meaningfully change wheel and tire fitment. Buyers looking at this truck often need to sort out whether it carries a 17-inch setup or the optional 20-inch package before choosing tires. Primary fitments for the 2005 Dodge Trucks Ram 1500 SLT are all radial, with 245/70R17, 265/70R17, 275/70R17, and 275/60R20 appearing across different sub-models. That makes this a fitment-first search, especially when comparing standard road-oriented sizing to off-road or appearance-package combinations. The right choice starts with the exact sub-model and wheel diameter already on the truck.
Which Tire Size Is Right for The 2005 Dodge Trucks Ram 1500 SLT
The 2005 Dodge Trucks Ram 1500 SLT uses four primary tire sizes, and they do not apply across every configuration. Sizes vary by sub-model and by wheel diameter, with both 17-inch and 20-inch fitments used on this truck. The first step is confirming the exact SLT configuration and whether the truck has the 17-inch setup, the 20 Inch Option, or an off-road package before selecting a tire.
Fit(s): (20 Inch Option), 4x2 Reg. Cab Rumble Bee, 4x4 Quad Cab Thunder Road, and w/Hemi Sport Pkg.
Construction: Radial|Rim: 20 in
A 275/60R20 tire uses a 275-millimeter nominal section width, a 60-series aspect ratio, radial construction, and a 20-inch rim diameter. On the 2005 Dodge Trucks Ram 1500 SLT, this size is tied to specific configurations such as the 20 Inch Option, Rumble Bee, Thunder Road, and Hemi Sport Package rather than the full SLT range. Its lower-profile metric layout gives it a different fitment context than the 17-inch sizes used elsewhere on the truck. Choosing this size starts with verifying that the truck actually has the 20-inch wheel package and adequate clearance for that setup.
A 245/70R17 tire combines a 245-millimeter section width with a 70-series profile, radial construction, and a 17-inch rim. This size appears on several 2005 Dodge Trucks Ram 1500 SLT 4x2 and 4x4 Quad Cab and Regular Cab configurations, making it one of the standard 17-inch fitments for the model. Available product selection in this size centers on BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls. It is a useful choice when the truck remains on its 17-inch wheel setup and the goal is matching the correct size before comparing load capacity and rim-width specifications.
A 265/70R17 tire is a metric radial size with a 265-millimeter nominal width, a 70-series aspect ratio, and a 17-inch rim diameter. On the 2005 Dodge Trucks Ram 1500 SLT, it shares duty with 245/70R17 across several 4x2 and 4x4 Quad Cab and Regular Cab versions, so it is important not to assume both sizes apply to every truck without checking the current wheel and tire setup. BFGoodrich All-Terrain T/A KO2 options are available here, both with raised white letter sidewalls and differing load specifications. This size deserves a closer look when a 17-inch SLT needs all-terrain capability within the correct fitment range.
A 275/70R17 tire uses a 275-millimeter section width, a 70-series profile, radial construction, and a 17-inch rim. For the 2005 Dodge Trucks Ram 1500 SLT, this size is associated with the 4x4 Quad Cab equipped with the Off-Road Package, so it serves a more specific role than the broader 17-inch fitments used on other SLT configurations. Its place in the lineup makes exact sub-model identification especially important before moving ahead with tire selection. This is the size to evaluate when the truck retains its off-road-oriented 17-inch configuration rather than the standard or 20-inch setups.
Tire fitment for the 2005 Dodge Trucks Ram 1500 SLT varies by cab style, drivetrain, and package. Checking the exact sub-model matters here because some versions use two possible 17-inch sizes, while others move to a dedicated 20-inch or off-road-specific fitment.

2005 Dodge Trucks Ram 1500 SLT (20 Inch Option)
This SLT configuration uses a dedicated 20-inch radial setup rather than the more common 17-inch fitments found elsewhere in the range. Tire selection starts with keeping the 20-inch wheel diameter in mind and then comparing the available tire style to the truck's current package and overall stance.
The 4x2 Quad Cab uses one of two 17-inch radial tire sizes, so the exact tire already on the truck should be confirmed before ordering replacements. That makes wheel and current-size verification more important than simply choosing by model name alone.
This Regular Cab 4x2 configuration also uses one of two 17-inch radial sizes rather than a single across-the-board fitment. Tire choice depends on confirming which size is mounted now and then matching the tire's load and rim-width suitability to that setup.
The Rumble Bee version uses the 20-inch radial fitment instead of the standard 17-inch sizes seen on many other SLT trucks. That points the tire search toward the correct wheel diameter first, then toward a tire that suits the truck's appearance package and existing wheel setup.
This 4x4 Quad Cab can use either of two 17-inch radial sizes, so tire selection is not as simple as choosing by drivetrain alone. The practical next step is checking the current size on the truck and making sure the replacement matches both the wheel diameter and intended use.
The Thunder Road package moves this Quad Cab to the 20-inch radial fitment rather than the standard 17-inch options used on other 4x4 Quad Cabs. That makes package identification especially important before comparing tires, since wheel diameter changes the fitment path immediately.
The Off-Road Package uses its own 17-inch radial tire size, separate from the other 17-inch choices found on several SLT sub-models. Tire selection here should stay focused on that package-specific fitment and the truck's actual wheel setup rather than assuming a standard SLT size.
This 4x4 Regular Cab shares the same two-size 17-inch fitment pattern seen on several other SLT versions. Replacing the tires correctly means confirming which of those two sizes the truck uses now before comparing tread style, load rating, and wheel compatibility.
The Hemi Sport Package uses the 20-inch radial fitment, placing it in the same wheel-diameter group as other appearance-oriented SLT variants. Tire selection should begin with that 20-inch setup and then focus on maintaining the right overall fitment for the truck's existing wheels.
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 Dodge Trucks Ram 1500 SLT Tires for Sale
Available product choices for this 2005 Dodge Trucks Ram 1500 SLT center on 17-inch BFGoodrich All-Terrain T/A KO2 tires. The current selection includes 245/70R17 and 265/70R17 fitments with raised white letter sidewalls, plus differing rim-width and load-capacity specifications worth comparing closely.
Common questions for the 2005 Dodge Trucks Ram 1500 SLT usually come down to identifying the right tire size by sub-model, confirming 17-inch versus 20-inch wheel fitment, and comparing the available radial tire choices for road use, appearance, and maintenance.
Tire Size & Fitment
What tire size fits a 2005 Dodge Trucks Ram 1500 SLT?
The 2005 Dodge Trucks Ram 1500 SLT uses four primary tire sizes: 245/70R17, 265/70R17, 275/70R17, and 275/60R20. These are all radial sizes, and they are tied to specific SLT configurations rather than applying to every truck with the same model name.
The important next step is identifying the exact sub-model and wheel diameter already on the truck. Several 4x2 and 4x4 Quad Cab and Regular Cab versions use one of two 17-inch sizes, while certain package trucks use a dedicated 20-inch fitment or the off-road-specific 275/70R17 size.
What size rim does a 2005 Dodge Trucks Ram 1500 SLT use?
A 2005 Dodge Trucks Ram 1500 SLT uses either a 17-inch or 20-inch rim, depending on the sub-model or package. The 245/70R17, 265/70R17, and 275/70R17 sizes all use 17-inch rims, while 275/60R20 uses a 20-inch rim.
Wheel diameter should be confirmed before comparing any tire options because it changes the fitment path immediately. Looking only at the truck's trim badge is not enough here, since SLT models span standard cab configurations, off-road versions, and option-package trucks with different wheel and tire combinations.
Why does the 2005 Dodge Trucks Ram 1500 SLT have more than one tire size?
The 2005 Dodge Trucks Ram 1500 SLT covers multiple cab styles, drivetrains, and package combinations, so tire fitment is not limited to one size. Standard 17-inch setups, off-road package fitment, and 20-inch appearance-package combinations all fall under the same model line.
That means tire selection starts with the truck's exact configuration, not just the year, make, and model. Checking the current tire size and the wheel diameter on the truck is the safest way to narrow the choices before comparing load capacity, sidewall presentation, or all-terrain versus other tire priorities.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2005 Dodge Trucks Ram 1500 SLT?
Start with basic fitment: the truck must be one of the SLT configurations that uses 265/70R17 on a 17-inch rim. In this size, available BFGoodrich All-Terrain T/A KO2 options share the same size code and raised white letter sidewall style, but they differ in load capacity, inflation reference, and weight.
Those differences matter if the truck sees cargo, towing, or rougher road use. Comparing the tire's rim-width specification, load figure, and general intended use will help narrow the choice, especially when the truck has aftermarket wheels or has been changed from its original wheel-and-tire combination.
What sidewall styles are available for 2005 Dodge Trucks Ram 1500 SLT tires?
The currently available 17-inch product choices for this 2005 Dodge Trucks Ram 1500 SLT use RWL sidewalls, meaning raised white letter styling. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 options available in the covered 245/70R17 and 265/70R17 sizes.
Sidewall style shapes the truck's presentation as much as tread design does, especially on a visible all-terrain tire. A raised white letter look tends to suit owners who want a more traditional truck appearance, but the first priority is still selecting the correct size and wheel diameter for the specific SLT configuration.
What brands offer tires for the 2005 Dodge Trucks Ram 1500 SLT?
Current product coverage for this 2005 Dodge Trucks Ram 1500 SLT includes BFGoodrich in the 17-inch sizes shown. The available tires are from the All-Terrain T/A KO2 series and are offered in 245/70R17 and 265/70R17 fitments.
Brand comparison only matters after the correct size has been confirmed, since this truck spans several different fitments. Once the tire size is settled, focus on the product's load capacity, rim-width range, sidewall style, and how the truck is actually used rather than choosing on brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 2005 Dodge Trucks Ram 1500 SLT?
A period-style choice for a 2005 Dodge Trucks Ram 1500 SLT starts with the tire size and wheel diameter that belong to the truck's exact sub-model or package. On trucks using the available 17-inch all-terrain options, a BFGoodrich All-Terrain T/A KO2 keeps the selection within a truck-appropriate radial format.
Appearance should come after fitment, since this SLT range includes multiple 17-inch and 20-inch combinations. Owners aiming for a more faithful early-2000s presentation should match the existing wheel setup first, then consider whether an all-terrain tread and raised white letter sidewall suit the truck's intended look.
How does tire construction affect the appearance of a restored 2005 Dodge Trucks Ram 1500 SLT?
For the 2005 Dodge Trucks Ram 1500 SLT, primary fitment is radial across all listed sizes. That means the visual decision is less about bias-ply versus radial and more about the exact tire size, sidewall treatment, wheel diameter, and whether the truck carries a standard 17-inch setup or a 20-inch package.
On a restoration-oriented truck from this era, proportions matter. A 17-inch off-road or all-terrain presentation reads differently than a 20-inch package truck, so the tire should support the truck's actual configuration rather than forcing a look that belongs to another SLT variant.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2005 Dodge Trucks Ram 1500 SLT?
Yes. Modifications such as aftermarket wheels, different wheel widths, suspension lifts, lowering changes, or body alterations can affect tire fitment on a 2005 Dodge Trucks Ram 1500 SLT. That matters even more on this truck because factory fitment already spans both 17-inch and 20-inch wheel diameters.
A truck that no longer has its original wheel-and-tire setup should be checked carefully before replacement. Pay attention to current rim diameter, wheel width, steering clearance, suspension travel, and fender space so the replacement tire matches the truck as it sits now, not just the trim name on paper.
What should I inspect before driving a 2005 Dodge Trucks Ram 1500 SLT on new tires?
Before road use, inspect tire pressure, lug nut torque, wheel condition, and visible clearance around the suspension, fenders, and steering components. It is also smart to confirm that all four tires match the intended size for the truck's exact SLT configuration and that the wheel diameter is correct.
A short low-speed test drive can help reveal rubbing, vibration, or pull before the truck goes back into normal service. Recheck pressure after the initial drive and keep an eye on any unusual contact marks, especially if the truck has aftermarket wheels or has moved from one factory fitment pattern to another.
How often should tires on a 2005 Dodge Trucks Ram 1500 SLT be inspected?
Tires on a 2005 Dodge Trucks Ram 1500 SLT should be inspected regularly, not just when tread looks worn. Check them before longer drives and periodically during normal use for air loss, uneven wear, cuts, bulges, sidewall cracking, or signs that the tire is contacting suspension or body components.
Trucks that sit for long periods still need attention because age and storage conditions can matter as much as mileage. Keeping the tires properly inflated and catching problems early helps preserve ride quality and fitment, especially on a model that may use different wheel diameters and load-capacity specifications across its range.
