The 2008 Dodge Trucks Ram 3500 SLT sits in the era when heavy-duty pickups had to balance daily work, towing confidence, and the larger cab choices buyers increasingly wanted. On a truck like this, tire selection is tied directly to configuration, because single-rear-wheel and dual-rear-wheel versions do not use the same size even though both ride on 17-inch rims. The primary fitments here are radial 265/70R17 and 235/80R17. Available choices center on BFGoodrich All-Terrain T/A KO2 products, with load capacity and sidewall presentation varying by size. The right decision starts with confirming the exact cab and wheel setup, then matching the tire to intended hauling, towing, and road use.
Which Tire Size Is Right for The 2008 Dodge Trucks Ram 3500 SLT
The 2008 Dodge Trucks Ram 3500 SLT uses two primary tire sizes, and the difference comes down to the exact sub-model. Both fitments are radial designs on 17-inch rims, but single-rear-wheel trucks use a different size than DRW configurations. The first step is identifying whether the truck is a Mega Cab or Quad Cab single-rear-wheel model, or a dual-rear-wheel Quad Cab or regular cab.
Fit(s): 4x2 Mega Cab, 4x2 Quad Cab, 4x4 Mega Cab, and 4x4 Quad Cab
Construction: Radial|Rim: 17 in
265/70R17 is a modern metric radial size in which 265 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 17 is the rim diameter in inches. On the 2008 Dodge Trucks Ram 3500 SLT, this size serves the single-rear-wheel configurations rather than the DRW trucks. Available examples in this size come from BFGoodrich in the All-Terrain T/A KO2 series with raised white letter sidewalls and different load-capacity specifications. It is the size to evaluate when the truck keeps its 17-inch SRW wheel setup and needs a tire matched to how the truck is actually used.
235/80R17 is a modern metric radial size where 235 gives the nominal section width in millimeters, 80 is the aspect ratio, R means radial construction, and 17 indicates the wheel diameter. On the 2008 Dodge Trucks Ram 3500 SLT, this size is used on the dual-rear-wheel configurations, making it distinct from the wider single-rear-wheel fitment. BFGoodrich offers this size in the All-Terrain T/A KO2 series with a black sidewall treatment and a rim-width range tailored to that application. It is the size to confirm when the truck has a DRW setup and needs a tire compatible with that wheel arrangement.
Sub-model fitment matters on the 2008 Dodge Trucks Ram 3500 SLT because tire size changes with the truck’s wheel configuration. Mega Cab and standard Quad Cab single-rear-wheel models use one size, while the DRW versions move to a different 17-inch radial fitment.

Best 2008 Dodge Trucks Ram 3500 SLT Tires for Sale
Available 17-inch tire choices for the 2008 Dodge Trucks Ram 3500 SLT center on BFGoodrich All-Terrain T/A KO2 radials. The main comparisons are between the 265/70R17 and 235/80R17 fitments, their sidewall presentation, rim-width range, and load-capacity specification.
Common questions for the 2008 Dodge Trucks Ram 3500 SLT usually come down to the correct tire size for each sub-model, 17-inch rim fitment, SRW versus DRW differences, product selection, and the checks worth making before hauling, towing, or regular road use.
Tire Size & Fitment
What tire size fits a 2008 Dodge Trucks Ram 3500 SLT?
The 2008 Dodge Trucks Ram 3500 SLT uses either 265/70R17 or 235/80R17, depending on the sub-model. Mega Cab and non-DRW Quad Cab versions use 265/70R17, while dual-rear-wheel Quad Cab and regular cab versions use 235/80R17. Both are radial tires designed for 17-inch rims.
The important next step is confirming whether the truck is single-rear-wheel or dual-rear-wheel before choosing a tire. Even though both sizes share the same rim diameter, they serve different wheel setups. Any truck that has been modified with aftermarket wheels or changes in rear axle configuration should be checked carefully before a new set is selected.
What size rim does a 2008 Dodge Trucks Ram 3500 SLT use?
The primary tire fitments for the 2008 Dodge Trucks Ram 3500 SLT both use a 17-inch rim. That applies to the 265/70R17 and 235/80R17 sizes, so rim diameter stays consistent even though the truck can have more than one tire size depending on configuration.
Rim diameter is only part of the fitment picture on a heavy-duty truck. Wheel width still matters, especially because the available 265/70R17 and 235/80R17 products do not share the same rim-width range. Checking the actual wheel size on the truck is worthwhile whenever the wheels may have been replaced, upgraded, or moved from SRW to DRW hardware.
Do all 2008 Dodge Trucks Ram 3500 SLT sub-models use the same tire size?
No. The 2008 Dodge Trucks Ram 3500 SLT uses more than one tire size across its covered sub-models. Single-rear-wheel Mega Cab and Quad Cab models use 265/70R17, while the dual-rear-wheel Quad Cab and regular cab models use 235/80R17.
That means the truck’s exact sub-model and wheel arrangement should be confirmed before comparing products. A Ram 3500 with dual rear wheels has a different fitment need than a single-rear-wheel truck, even when both carry SLT trim and use 17-inch rims. Verifying the current wheels and tire placard helps avoid selecting a tire meant for the wrong configuration.
Choosing the Right Tire
What should I consider when choosing a tire for a 2008 Dodge Trucks Ram 3500 SLT?
Start with the correct primary size for the truck’s exact setup: 265/70R17 for the single-rear-wheel configurations and 235/80R17 for the DRW versions. From there, compare construction, load-capacity specification, rim-width compatibility, and the type of service the truck actually sees, such as towing, hauling, or general road use.
A heavy-duty pickup asks more from its tires than a light-use commuter vehicle. Matching the tire to the wheel setup and intended workload matters more than choosing by appearance alone. It is also worth checking whether the truck still wears its original wheel arrangement, because aftermarket wheels can change the fitment decision even when the nominal rim diameter remains 17 inches.
What sidewall styles are available for 2008 Dodge Trucks Ram 3500 SLT tires?
The available sidewall styles differ by size on the 2008 Dodge Trucks Ram 3500 SLT. 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.
That difference matters mostly for appearance, but it can also help distinguish which tire belongs on which wheel setup. Sidewall style should come after the basic fitment checks, not before them. Once the correct size is confirmed for the truck’s SRW or DRW configuration, the sidewall presentation becomes part of the final choice rather than the starting point.
What tire series are available for the 2008 Dodge Trucks Ram 3500 SLT?
The available products for the 2008 Dodge Trucks Ram 3500 SLT are in the BFGoodrich All-Terrain T/A KO2 series. That series appears in both 265/70R17 and 235/80R17, so the main difference is not the series name itself but the size, sidewall style, and specification attached to each fitment.
A buyer comparing these tires should pay close attention to the exact size and load-capacity figure rather than assuming every KO2 in a 17-inch diameter serves the same job. On a Ram 3500, that matters because the tire has to match the truck’s wheel configuration and intended workload, especially when the truck is used for towing or carrying heavier loads.
Restoration & Appearance
Which tire should I choose for a period-style 2008 Dodge Trucks Ram 3500 SLT?
A period-style choice for a 2008 Dodge Trucks Ram 3500 SLT starts with using the correct original fitment format for the truck’s configuration: 265/70R17 on SRW models or 235/80R17 on DRW models. Since the primary fitments are modern radial truck sizes, the closest period-style approach is usually maintaining the proper size and overall visual character for the era.
Appearance should still be balanced against the truck’s working role. A Ram 3500 often needs tire specifications that support hauling and towing demands, so fitment and load suitability matter alongside visual consistency. For owners pursuing a highly exact restoration presentation, original sales literature, marque references, and surviving examples can help narrow down era-appropriate appearance details.
How does tire construction affect the appearance of a restored 2008 Dodge Trucks Ram 3500 SLT?
On the 2008 Dodge Trucks Ram 3500 SLT, the primary fitments are radial tires, so retaining radial construction keeps the truck in the sizing and visual language associated with its model year. Construction matters less here as a vintage styling question than it would on an older classic with bias-ply fitment.
The more noticeable appearance differences come from sidewall treatment, tread character, and the stance created by using the correct size for SRW or DRW setup. A restored truck can look right only when the tire size matches the wheel arrangement. Using the wrong fitment can change the truck’s presentation even before any road-use or clearance issue appears.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2008 Dodge Trucks Ram 3500 SLT?
Yes. Wheel changes, suspension alterations, leveling kits, lifts, and axle-related changes can all affect tire fitment on a 2008 Dodge Trucks Ram 3500 SLT. That matters even more on this truck because its correct size already depends on whether the setup is single-rear-wheel or dual-rear-wheel.
A modified truck should be checked for actual wheel width, tire clearance, and steering clearance before replacement tires are chosen. The fact that both primary sizes use 17-inch rims does not make them interchangeable across every setup. Looking at the current wheels and confirming the truck’s real configuration is the safest way to avoid ordering the wrong specification.
What should I inspect before driving a 2008 Dodge Trucks Ram 3500 SLT on new tires?
Before putting a 2008 Dodge Trucks Ram 3500 SLT into regular service on new tires, inspect wheel condition, valve stems, inflation pressure, and basic suspension and steering health. It is also wise to confirm that the installed tire size matches the truck’s SRW or DRW configuration and that all tires are seated properly on the correct 17-inch wheels.
After installation, recheck clearance at full steering lock and under normal loaded ride height, especially if the truck tows or carries weight. Lug torque, air retention, and early wear pattern should be monitored during the first several drives. Those quick follow-up checks can reveal issues with alignment, wheel condition, or incorrect setup before they become larger problems.
What should I check before a longer drive in a 2008 Dodge Trucks Ram 3500 SLT?
Before a longer trip in a 2008 Dodge Trucks Ram 3500 SLT, check tire pressure, visible tread and sidewall condition, and any signs of cuts, bulges, or irregular wear. On a truck that may tow or haul, it also makes sense to verify that the tire size and load-capacity specification suit the way the truck will be used.
Longer drives tend to expose small problems that short local use may not reveal. A final walkaround should include looking for air loss, checking dual-rear-wheel spacing on DRW trucks, and making sure the tires clear suspension and body components normally. Trucks that spend long periods parked should get an extra look for age-related cracking before heading back onto the road.
