The 2008 Dodge Trucks Ram 1500 SLT comes from a period when half-ton pickups were expected to handle daily driving, towing duty, and weekend use without giving up a strong visual stance. In SLT trim, that means tire choice is tied closely to cab and bed configuration, as well as wheel diameter. This Ram 1500 SLT uses radial tires in either 265/70R17 or 275/60R20 fitment, so the first step is confirming the exact sub-model and wheel setup. Current choices here center on a truck-oriented all-terrain radial in 265/70R17. Getting the right size matters not just for appearance, but for load capability, clearance, and overall road manners.
Which Tire Size Is Right for The 2008 Dodge Trucks Ram 1500 SLT
The 2008 Dodge Trucks Ram 1500 SLT uses two primary tire sizes, and the correct one depends on the exact cab and bed configuration as well as wheel diameter. Both fitments are radial, but one uses a 17-inch rim and the other uses a 20-inch rim, so confirming the truck's actual wheel setup is the first step before comparing tire choices.
Fit(s): 4x2 Mega Cab, 4x2 Quad Cab Long Bed, 4x2 Reg. Cab, 4x4 Mega Cab, 4x4 Quad Cab Long Bed, and 4x4 Reg. Cab
Construction: Radial|Rim: 17 in
265/70R17 is a metric radial size in which 265 identifies the nominal section width in millimeters, 70 is the aspect ratio, R designates radial construction, and 17 is the rim diameter in inches. On the 2008 Dodge Trucks Ram 1500 SLT, this size supports a practical truck fitment with a 17-inch wheel. Available choices in this size include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls and differing load capacities. It is the size to focus on when the truck is equipped with the 17-inch wheel setup used on several SLT sub-models.
Fit(s): 4x2 Quad Cab Short Bed, 4x2 Reg. Cab, 4x4 Quad Cab Short Bed, and 4x4 Reg. Cab
Construction: Radial|Rim: 20 in
275/60R20 is also a metric radial size, with 275 indicating nominal section width in millimeters, 60 describing the aspect ratio, and 20 identifying the required rim diameter in inches. For the 2008 Dodge Trucks Ram 1500 SLT, this fitment belongs to configurations using a 20-inch wheel rather than the 17-inch setup. The lower-profile relationship compared with the 17-inch fitment makes wheel confirmation especially important before selection. This is the size to evaluate when the truck's sub-model or current wheel package calls for the 20-inch rim.
Tire fitment on the 2008 Dodge Trucks Ram 1500 SLT varies by sub-model, and some regular cab versions can use either of the two primary sizes. Checking the exact cab and bed configuration matters because it also determines whether the truck uses a 17-inch or 20-inch wheel.

Best 2008 Dodge Trucks Ram 1500 SLT Tires for Sale
Current product choices for the 2008 Dodge Trucks Ram 1500 SLT center on 265/70R17, with BFGoodrich All-Terrain T/A KO2 options featuring raised white letter sidewalls. These tires share the same size and series but differ in load capacity, inflation pairing, and weight.
Owners of a 2008 Dodge Trucks Ram 1500 SLT usually need to confirm the right tire size by sub-model and wheel diameter, then compare radial tire specifications, sidewall style, load capacity, and basic road-use checks before installation.
Tire Size & Fitment
What tire size fits a 2008 Dodge Trucks Ram 1500 SLT?
The 2008 Dodge Trucks Ram 1500 SLT uses either 265/70R17 or 275/60R20, depending on the sub-model and wheel setup. Both are radial tire sizes, but they are not interchangeable primary fitments because they require different rim diameters.
The practical first step is identifying the exact SLT configuration and confirming whether the truck has 17-inch or 20-inch wheels. Regular cab versions can use either size, while several Mega Cab and Quad Cab configurations are tied to one specific fitment, so wheel diameter and sub-model should be checked before replacement.
What size rim does a 2008 Dodge Trucks Ram 1500 SLT use?
A 2008 Dodge Trucks Ram 1500 SLT uses either a 17-inch rim with 265/70R17 tires or a 20-inch rim with 275/60R20 tires. The correct rim size depends on the truck's exact sub-model and wheel package.
That makes the wheel itself an important part of the tire decision. A buyer should confirm the actual wheel diameter on the truck before selecting tires, especially on regular cab models that may appear in either fitment. Any past wheel change, aftermarket package, or used-vehicle variation makes that inspection even more important.
Why does the 2008 Dodge Trucks Ram 1500 SLT have more than one tire size?
The 2008 Dodge Trucks Ram 1500 SLT has more than one tire size because fitment changes across cab and bed configurations, and some versions use a different wheel diameter. The two primary sizes are 265/70R17 and 275/60R20.
That means the right tire is tied to the truck's exact configuration rather than the SLT badge alone. A Mega Cab, Quad Cab, or regular cab may not share the same fitment, and a 17-inch tire cannot be mounted on a 20-inch wheel. Confirming the sub-model and measuring the wheel prevents costly mistakes.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2008 Dodge Trucks Ram 1500 SLT?
Start with the correct 265/70R17 fitment, then compare tire construction, rim-width compatibility, load capacity, and intended use. In this size, available BFGoodrich All-Terrain T/A KO2 options share the same basic fitment and raised white letter sidewall style, but they differ in specification.
One version carries 2,470 lbs at 50 psi, while another carries 3,195 lbs at 80 psi, so the truck's use matters. Matching the tire to the wheel width is also important, and these 265/70R17 tires are built for 7.0- to 9.0-inch rim widths. Tire choice should reflect both the wheel and the truck's workload.
What sidewall styles are available for 2008 Dodge Trucks Ram 1500 SLT tires?
The available 265/70R17 products for the 2008 Dodge Trucks Ram 1500 SLT use an RWL sidewall, which means raised white letter styling. That gives the truck a more traditional performance-truck and all-terrain appearance than a plain black sidewall.
Sidewall style does not change the basic fitment, but it does affect the truck's finished look. Buyers who want a more period truck presentation often pay close attention to that detail, especially on a visible size like 265/70R17. Appearance should still come after confirming the correct size, load specification, and wheel compatibility.
What brands offer tires for the 2008 Dodge Trucks Ram 1500 SLT?
Current product coverage for the 2008 Dodge Trucks Ram 1500 SLT in 265/70R17 includes BFGoodrich. The available tire is from the All-Terrain T/A KO2 series, offered in more than one specification within the same size.
Brand is only one part of the decision. Once the correct size is confirmed, compare the available specifications within that brand, including load capacity, inflation pairing, rim-width suitability, and tire weight. That approach is more useful than choosing by name alone, especially on a truck that may see hauling, towing, or mixed-use driving.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Dodge Trucks Ram 1500 SLT?
For a period-style 2008 Dodge Trucks Ram 1500 SLT, the starting point is the correct factory-era fitment size for the truck's exact sub-model and wheel diameter: either 265/70R17 or 275/60R20. Preserving the right overall look begins with keeping the proper wheel-and-tire relationship.
Within the currently covered 265/70R17 choices, an all-terrain radial with raised white letters gives the truck a strong late-2000s pickup appearance. Buyers focused on exact originality should also compare the truck against build records, photos, or marque-specific references, since appearance details like sidewall treatment can vary by wheel package and prior owner changes.
Does correct tire fitment matter for a 2008 Dodge Trucks Ram 1500 SLT restoration?
Correct tire fitment matters because the wrong size can change the truck's stance, wheel-to-tire proportion, and overall presentation. On a 2008 Dodge Trucks Ram 1500 SLT, that begins with selecting the proper 265/70R17 or 275/60R20 fitment for the exact sub-model and wheel diameter.
Appearance is only part of the issue. An incorrect rim diameter or mismatched tire specification can also affect load suitability and clearance around suspension or body components. Even on a modern-era collectible truck, getting the fundamentals right usually produces a result that looks more coherent and functions more like the vehicle was intended to.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Dodge Trucks Ram 1500 SLT?
Yes. Modifications can affect tire fitment on a 2008 Dodge Trucks Ram 1500 SLT, especially if the truck has aftermarket wheels, altered ride height, suspension changes, or body modifications. Those changes can influence whether the original 265/70R17 or 275/60R20 fitment still matches the truck's current setup.
A replacement tire should be checked against the actual wheel diameter and width on the truck, along with clearance at full steering lock and through suspension movement. Even when the tire size itself is correct for the model, changes made over the years can create a very different fitment situation from one SLT to another.
What should I inspect before driving a 2008 Dodge Trucks Ram 1500 SLT on new tires?
Before driving a 2008 Dodge Trucks Ram 1500 SLT on new tires, inspect wheel condition, valve stems, lug hardware, and overall tire pressure. It also helps to confirm that the tire size matches the truck's wheel diameter and that the tire seats properly on the rim.
A short first drive should include listening for rubbing, checking steering response, and rechecking inflation after the tires have settled in. On a truck used for hauling or towing, load capacity deserves extra attention as well. Early inspection can catch clearance or setup problems before they become wear issues.
How often should tires on a 2008 Dodge Trucks Ram 1500 SLT be inspected?
Tires on a 2008 Dodge Trucks Ram 1500 SLT should be inspected regularly, not just when tread looks low. Pressure, tread wear, cuts, bulges, cracking, and uneven shoulder wear all deserve routine attention, especially on a truck that may alternate between light use and heavier work.
A quick inspection before longer drives is a sensible habit, and any vibration or pull should be checked promptly. Trucks stored for stretches can develop age-related issues even when tread remains deep, so condition matters as much as mileage. Consistent inspection helps protect tire life, ride quality, and fitment confidence.
