The 2008 Dodge Trucks Ram 3500 SXT sits in the heavy-duty pickup market where payload, towing ability, and wheel configuration matter just as much as everyday road manners. Buyers looking at this exact truck are often sorting out more than one tire size because single-rear-wheel and dual-rear-wheel versions do not use the same fitment. This Ram 3500 SXT uses radial tires in either 265/70R17 or 235/80R17, both on 17-inch rims. Available choices stay within BFGoodrich's All-Terrain T/A KO2 line, with differences in load specification and sidewall presentation. The key step is matching the tire size to the truck's exact cab and rear-wheel setup before comparing the available options.
Which Tire Size Is Right for The 2008 Dodge Trucks Ram 3500 SXT
The 2008 Dodge Trucks Ram 3500 SXT uses two primary tire sizes, and the difference comes down to the truck's exact configuration rather than a simple styling choice. Both are radial tires on 17-inch wheels, but identifying whether the truck is a single-rear-wheel Quad Cab or a dual-rear-wheel version is the first step before choosing a tire.
265/70R17 is a metric radial size in which 265 is the nominal section width in millimeters, 70 is the aspect ratio, and 17 is the wheel diameter in inches. On the 2008 Dodge Trucks Ram 3500 SXT, this size is used on certain single-rear-wheel Quad Cab configurations, making it the fitment to confirm before looking at load specification details. Available choices in this size come from BFGoodrich in the All-Terrain T/A KO2 series with raised white letter sidewalls. It is the size to evaluate when the truck needs a 17-inch radial with a wider section and the correct match for those specific non-DRW setups.
235/80R17 is a metric radial size where 235 states the nominal section width in millimeters, 80 identifies the aspect ratio, and 17 designates the wheel diameter in inches. On the 2008 Dodge Trucks Ram 3500 SXT, this size is tied to the dual-rear-wheel configurations, so it serves a different role than the 265/70R17 fitment. BFGoodrich offers this size in the All-Terrain T/A KO2 line with an RBL sidewall. It is the size to confirm when the truck carries the DRW setup, since that configuration affects both tire selection and wheel compatibility.
Tire fitment for the 2008 Dodge Trucks Ram 3500 SXT changes by cab and rear-wheel configuration. Checking the exact sub-model matters because single-rear-wheel Quad Cab trucks use a different size than the dual-rear-wheel versions, even though all of them use 17-inch radial tires.

2008 Dodge Trucks Ram 3500 SXT 4x2 Quad Cab
The 2008 Dodge Trucks Ram 3500 SXT 4x2 Quad Cab uses the 265/70R17 radial fitment rather than the narrower DRW size. Tire selection here centers on choosing the right load specification within that size and confirming the truck still retains its original wheel setup.
The 2008 Dodge Trucks Ram 3500 SXT 4x2 Quad Cab (DRW) uses the 235/80R17 radial tire size. For this dual-rear-wheel configuration, the main priority is staying with the correct DRW fitment and checking wheel compatibility before comparing tire details.
The 2008 Dodge Trucks Ram 3500 SXT 4x2 Reg. Cab (DRW) also uses the 235/80R17 radial size. That keeps tire choice focused on the proper dual-rear-wheel application rather than appearance differences, with wheel width and overall truck setup worth confirming first.
The 2008 Dodge Trucks Ram 3500 SXT 4x4 Quad Cab uses the 265/70R17 radial tire size. Buyers with this configuration should focus on choosing within that size and verifying that any wheel or suspension changes have not altered the truck's fitment requirements.
The 2008 Dodge Trucks Ram 3500 SXT 4x4 Quad Cab (DRW) uses the 235/80R17 radial fitment. That makes correct dual-rear-wheel sizing the first concern, followed by checking the wheel package and the tire's intended working load for the truck's use.
The 2008 Dodge Trucks Ram 3500 SXT 4x4 Reg. Cab (DRW) uses the 235/80R17 radial size as part of its dual-rear-wheel setup. Tire choice here is less about styling variety and more about keeping the correct size and compatible wheel dimensions in place.

Tire Size & Fitment
What tire size fits a 2008 Dodge Trucks Ram 3500 SXT?
The 2008 Dodge Trucks Ram 3500 SXT uses either 265/70R17 or 235/80R17, depending on the truck's exact configuration. Single-rear-wheel Quad Cab versions use 265/70R17, while the dual-rear-wheel models use 235/80R17. Both are radial sizes mounted on 17-inch wheels.
The important step is identifying the truck's cab and rear-wheel setup before choosing a tire. A DRW Ram 3500 SXT should stay with the correct dual-rear-wheel fitment, while a non-DRW Quad Cab uses the wider 265/70R17. If the truck has aftermarket wheels or suspension changes, check the actual wheel dimensions and clearance before replacing tires.
What size rim does a 2008 Dodge Trucks Ram 3500 SXT use?
Both tire sizes used on the 2008 Dodge Trucks Ram 3500 SXT fit 17-inch rims. That applies to the 265/70R17 size used on certain Quad Cab models and the 235/80R17 size used on the dual-rear-wheel versions. The tire size changes by configuration, but the wheel diameter stays the same.
Wheel diameter is only one part of fitment, so it is worth checking wheel width as well. The available 265/70R17 tires are matched to a different rim-width range than the 235/80R17 option. On a heavy-duty truck like the Ram 3500 SXT, confirming both wheel size and the correct sub-model fitment helps avoid choosing a tire that suits the wrong configuration.
Why does the 2008 Dodge Trucks Ram 3500 SXT have more than one tire size?
The two tire sizes reflect different versions of the 2008 Dodge Trucks Ram 3500 SXT rather than interchangeable choices for the same truck. The 265/70R17 size belongs to certain single-rear-wheel Quad Cab models, while 235/80R17 is used on the dual-rear-wheel configurations. Both sizes are radial and both use 17-inch rims.
That means tire selection starts with the truck's actual rear-wheel layout. A DRW truck has different fitment needs than a single-rear-wheel truck, even when the wheel diameter matches. Before replacing tires, confirm the exact sub-model and check whether the truck still uses its original wheels, since prior modifications can complicate what size belongs on the vehicle now.
Choosing the Right Tire
What should I consider when choosing a tire for a 2008 Dodge Trucks Ram 3500 SXT?
Start with the correct primary size for the truck's exact configuration: 265/70R17 for certain single-rear-wheel Quad Cab models or 235/80R17 for dual-rear-wheel versions. From there, compare construction, load specification, rim-width compatibility, and the kind of use the truck sees. All of the available options here are radial BFGoodrich All-Terrain T/A KO2 tires.
The best comparison points are the truck's wheel setup and how much carrying or towing duty it sees. The 265/70R17 offerings include different load capacities, while the 235/80R17 choice serves the DRW fitment directly. Looking at sidewall style and tire series matters too, but those choices only make sense after the correct size and wheel match are confirmed.
What sidewall styles are available for 2008 Dodge Trucks Ram 3500 SXT tires?
The available sidewall styles for the 2008 Dodge Trucks Ram 3500 SXT vary by tire size. The 265/70R17 BFGoodrich All-Terrain T/A KO2 options use an RWL sidewall, while the 235/80R17 BFGoodrich All-Terrain T/A KO2 uses an RBL sidewall. Those sidewall differences are tied to the specific fitment rather than a universal styling choice.
That matters because sidewall appearance should be considered after the truck's correct tire size is settled. A single-rear-wheel truck and a dual-rear-wheel truck do not draw from the same size, so sidewall style follows fitment rather than the other way around. Once the right size is confirmed, sidewall treatment becomes part of the final product comparison.
What brands offer tires for the 2008 Dodge Trucks Ram 3500 SXT?
BFGoodrich is the brand available for the 2008 Dodge Trucks Ram 3500 SXT in the sizes covered here. The offerings are within the All-Terrain T/A KO2 series, with options in 265/70R17 for certain single-rear-wheel trucks and 235/80R17 for the dual-rear-wheel versions. Construction remains radial across both sizes.
Since the choices stay within one brand and one tire series, the main comparisons shift to size, load specification, sidewall style, and rim-width compatibility. That can actually simplify selection, because the first decision is not brand preference but matching the tire to the truck's exact configuration. After that, compare the available product details within the correct size.
Restoration & Appearance
Does correct tire fitment matter for a 2008 Dodge Trucks Ram 3500 SXT restoration?
Correct tire fitment still matters on a 2008 Dodge Trucks Ram 3500 SXT, even though this is a newer heavy-duty truck rather than an early collector car. The right starting point is using the proper size for the truck's exact configuration, with 265/70R17 used on certain single-rear-wheel Quad Cab models and 235/80R17 used on DRW versions.
A restoration-minded owner should avoid treating those sizes as interchangeable just because both fit 17-inch wheels. Tire size affects the truck's stance, working setup, and overall presentation, especially on a dually. When originality matters, also verify whether the truck still carries its correct wheel type and dimensions before settling on a final tire choice.
How does tire construction affect the appearance of a restored 2008 Dodge Trucks Ram 3500 SXT?
On the 2008 Dodge Trucks Ram 3500 SXT, the primary fitments are radial tires, so construction choice is less about switching between eras and more about keeping the truck in the style of its original heavy-duty setup. The visible appearance differences here come more from size and sidewall treatment than from a bias-ply-versus-radial decision.
That means a restored or carefully kept Ram 3500 SXT should first wear the correct size for its exact configuration. After that, details such as RWL versus RBL sidewall presentation can influence how the truck looks. For owners focused on authenticity, matching the proper wheel and tire combination is usually more important than chasing a dramatic change in construction style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Dodge Trucks Ram 3500 SXT?
Yes, modifications can affect tire fitment on a 2008 Dodge Trucks Ram 3500 SXT even when the original tire size is known. Aftermarket wheels, suspension changes, leveling kits, or prior conversions between wheel setups can all change the space available around the tire. That is especially important when the truck's correct size already depends on whether it is single-rear-wheel or DRW.
A truck that has been altered should be checked for actual wheel diameter, wheel width, and clearance before replacement tires are chosen. On dual-rear-wheel models, spacing and compatibility matter just as much as the nominal tire size. Looking over the full setup first helps prevent selecting a tire that matches the original fitment on paper but not the truck as it sits today.
What should I inspect before driving a 2008 Dodge Trucks Ram 3500 SXT on new tires?
Before road use, inspect air pressure, wheel hardware, valve stems, tread seating, and overall clearance around the tire. It is also smart to look at the truck's suspension, steering components, and alignment condition, since a heavy-duty Ram 3500 SXT places real demand on its tires. On DRW trucks, pay close attention to the rear-wheel setup and spacing.
A short test drive followed by a second visual inspection can reveal rubbing, unusual wear patterns, or pressure loss early. The right habit is checking the truck as a complete system rather than treating tires as an isolated part. That approach is especially useful when the vehicle is used for towing, hauling, or has spent time sitting before returning to regular road use.
How often should tires on a 2008 Dodge Trucks Ram 3500 SXT be inspected?
Tires on a 2008 Dodge Trucks Ram 3500 SXT should be inspected regularly, not just at replacement time. A heavy-duty pickup benefits from routine checks for pressure loss, uneven wear, cuts, bulges, punctures, and sidewall damage. Trucks that tow or carry heavier loads deserve even closer attention because tire condition can change more quickly under work use.
A practical routine is to inspect the tires before longer trips and to give them a quick visual check during normal use. Also look at age-related condition if the truck is driven infrequently. On a dually, make sure the rear tires are wearing evenly and that nothing in the wheel or suspension setup is causing clearance or contact issues.
