The 2011 RAM Trucks 3500 ST sits firmly in the heavy-duty pickup world, built for owners who need one-ton capability rather than light-duty comfort alone. In this era, the 3500 earned its place with work-focused chassis choices that could vary meaningfully between single-rear-wheel and dual-rear-wheel configurations. Tire fitment follows that same practical logic, with this model using either 265/70R17 or 235/80R17 radial tires on 17-inch rims depending on the exact setup. Available choices center on BFGoodrich All-Terrain T/A KO2 products, with differences in load specification, rim-width range, and sidewall presentation. The key is matching the tire to the truck's exact sub-model and wheel setup before comparing the available options.
Which Tire Size Is Right for The 2011 RAM Trucks 3500 ST
The 2011 RAM Trucks 3500 ST uses two primary tire sizes, and the correct one depends on whether the truck is a single-rear-wheel or dual-rear-wheel configuration. Both fitments are radial tires for 17-inch rims, so the first step is confirming the exact sub-model rather than assuming every 3500 ST uses the same size. Once that is settled, the buying decision shifts to load specification, rim-width compatibility, and the tire's overall intended use.
A 265/70R17 uses a nominal section width of 265 millimeters, a 70-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2011 RAM Trucks 3500 ST, this size belongs to the single-rear-wheel 4x2 and 4x4 configurations, making it the key fitment for trucks without dual rear wheels. Available choices in this size come from BFGoodrich in the All-Terrain T/A KO2 series with raised white letter styling and differing load specifications. This is the size to evaluate when the truck needs a 17-inch radial with heavier-duty pickup capability in a single-rear-wheel setup.
A 235/80R17 uses a nominal section width of 235 millimeters, an 80-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2011 RAM Trucks 3500 ST, this size is used on the dual-rear-wheel versions, where the tire choice needs to match the dually wheel and axle arrangement rather than the single-rear-wheel trucks. The available BFGoodrich All-Terrain T/A KO2 option in this size uses a black sidewall presentation and its own rim-width range. This fitment should be chosen only after confirming the truck is a DRW model and that the wheel setup matches the intended tire.
Sub-model fitment matters on the 2011 RAM Trucks 3500 ST because single-rear-wheel and dual-rear-wheel trucks do not use the same tire size. Once the exact drivetrain and rear-wheel configuration are confirmed, the correct 17-inch radial size becomes much easier to narrow down.

2011 RAM Trucks 3500 ST 4x2
The 2011 RAM Trucks 3500 ST 4x2 uses the 265/70R17 radial tire size. That makes the selection process more about comparing the available load specification and wheel-width compatibility within that size than deciding between multiple primary fitments.
The 2011 RAM Trucks 3500 ST 4x2 (DRW) uses the 235/80R17 radial tire size. Tire selection here starts with confirming the truck's dual-rear-wheel setup and making sure the chosen tire suits the dually wheel arrangement rather than a single-rear-wheel application.
The 2011 RAM Trucks 3500 ST 4x4 uses the 265/70R17 radial tire size. With the correct size established, the next step is comparing the available tire version against the truck's wheel width and the load demands expected in actual use.
The 2011 RAM Trucks 3500 ST 4x4 (DRW) uses the 235/80R17 radial tire size. This fitment should be matched carefully to the truck's dual-rear-wheel configuration so the tire choice aligns with the wheel setup and heavy-duty service role.
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 2011 RAM Trucks 3500 ST Tires for Sale
Available 2011 RAM Trucks 3500 ST tires center on BFGoodrich All-Terrain T/A KO2 products in both primary 17-inch sizes. The key comparisons are size-specific rim-width range, sidewall treatment, and load specification, especially between the 265/70R17 single-rear-wheel fitment and the 235/80R17 dually fitment.
Common 2011 RAM Trucks 3500 ST tire questions usually come down to identifying the correct size for SRW or DRW use, understanding 17-inch rim fitment, and comparing the available radial tire choices for work, replacement, and road-use confidence.
Tire Size & Fitment
What tire size fits a 2011 RAM Trucks 3500 ST?
The 2011 RAM Trucks 3500 ST uses either 265/70R17 or 235/80R17, depending on the exact sub-model. Single-rear-wheel 4x2 and 4x4 trucks use 265/70R17, while dual-rear-wheel 4x2 (DRW) and 4x4 (DRW) trucks use 235/80R17.
The important point is that both sizes use a 17-inch rim, but they are not the same fitment. Tire selection should start with confirming whether the truck is SRW or DRW, then checking the wheel setup on the vehicle now, especially if it has had wheel, suspension, or axle-related changes over time.
What size rim does a 2011 RAM Trucks 3500 ST use?
The 2011 RAM Trucks 3500 ST uses 17-inch rims with both of its primary tire sizes. That applies to the 265/70R17 fitment used on single-rear-wheel models and the 235/80R17 fitment used on dual-rear-wheel versions.
Rim diameter is only part of the fitment picture on a heavy-duty truck like this. Width matters too, so the chosen tire should be matched to the wheel's actual width and intended service, particularly on a dually where the wheel arrangement differs from a standard single-rear-wheel setup.
Why does the 2011 RAM Trucks 3500 ST have more than one tire size?
The 2011 RAM Trucks 3500 ST has more than one tire size because the sub-model lineup includes both single-rear-wheel and dual-rear-wheel configurations. The SRW trucks use 265/70R17, while the DRW trucks use 235/80R17, even though both are radial tires for 17-inch rims.
That means the correct choice is tied to how the truck is configured, not just the model name on the badge. A buyer should confirm the exact sub-model and inspect the truck's current wheel setup before ordering, since modified wheels or swapped axle components can change what is actually on the vehicle.
Choosing the Right Tire
What should I consider when choosing a tire for a 2011 RAM Trucks 3500 ST?
Start with the correct primary size for the truck's configuration. A 2011 RAM Trucks 3500 ST uses 265/70R17 in single-rear-wheel form and 235/80R17 in dual-rear-wheel form, so the first decision is matching the tire to the actual SRW or DRW setup.
After that, compare the tire's load specification, approved rim-width range, and sidewall style. A heavy-duty pickup can place very different demands on its tires depending on cargo, towing, and wheel choice, so the best comparison is the one that matches the truck's real use and actual wheel dimensions.
What sidewall styles are available for 2011 RAM Trucks 3500 ST tires?
Sidewall style varies by size on the 2011 RAM Trucks 3500 ST. The available 265/70R17 BFGoodrich All-Terrain T/A KO2 options use RWL styling, while the available 235/80R17 BFGoodrich All-Terrain T/A KO2 uses an RBL sidewall presentation.
That gives the truck owner an appearance difference as well as a fitment difference tied to sub-model. Sidewall style should be considered only after the correct tire size is confirmed, since visual preference does not override the need to match the tire to the truck's SRW or DRW wheel arrangement.
What tire series are available for the 2011 RAM Trucks 3500 ST?
The available tire series for the 2011 RAM Trucks 3500 ST is BFGoodrich All-Terrain T/A KO2. It appears in both primary fitments, giving the truck a consistent all-terrain product family across the 265/70R17 and 235/80R17 sizes.
Even within the same series, the details still matter. The 265/70R17 choices vary in load specification, and the 235/80R17 dually fitment has its own rim-width range and sidewall treatment, so comparing the underlying specifications remains important even when the series name stays the same.
Restoration & Appearance
Does correct tire fitment matter for a 2011 RAM Trucks 3500 ST restoration?
Yes, correct tire fitment still matters on a 2011 RAM Trucks 3500 ST even when the goal is a clean, stock-style presentation rather than a concours-era restoration. The right starting point is using the proper size for the truck's configuration: 265/70R17 for SRW models and 235/80R17 for DRW models.
Appearance choices should follow fitment, not replace it. Matching the tire to the correct wheel setup helps the truck keep the stance and working character appropriate to its configuration, while incorrect sizing can change the visual balance and create avoidable clearance or load-related concerns.
How does tire construction affect the appearance of a restored 2011 RAM Trucks 3500 ST?
On the 2011 RAM Trucks 3500 ST, primary fitment stays within modern radial construction, so the appearance question is more about the tire's profile and sidewall treatment than about choosing between bias-ply and radial. In this application, the visible difference comes from the correct size and whether the sidewall is RWL or RBL.
That matters because a truck restored to a clean, work-ready look benefits from a tire that suits its actual configuration. A single-rear-wheel truck with 265/70R17 and a dually with 235/80R17 present differently, so keeping the proper size and sidewall style aligned with the truck helps preserve a coherent finished look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 RAM Trucks 3500 ST?
Yes, modifications can affect tire fitment on a 2011 RAM Trucks 3500 ST even when the truck still uses a 17-inch wheel. Aftermarket wheels, suspension changes, ride-height adjustments, or axle-related changes can alter the wheel width, clearance, or overall setup enough to complicate the original tire choice.
That is especially important when distinguishing between 265/70R17 SRW and 235/80R17 DRW applications. A truck that has been altered should be checked for actual wheel width, steering and fender clearance, and rear-wheel configuration before replacement tires are selected simply by model year and trim name.
What should I inspect before driving a 2011 RAM Trucks 3500 ST on new tires?
Before driving a 2011 RAM Trucks 3500 ST on new tires, inspect the wheels for damage, confirm the correct tire size for the truck's SRW or DRW configuration, and make sure inflation is set appropriately for the tire and intended use. Lug hardware, valve stems, and general wheel condition deserve attention as well.
A short clearance check is also worthwhile before regular road use. Turn the steering through its full range on SRW trucks, look for any contact concerns, and confirm that a dually setup has proper spacing and no visible interference. Early inspection helps catch fitment issues before they become wear or handling problems.
How should tires on a 2011 RAM Trucks 3500 ST be maintained?
Tires on a 2011 RAM Trucks 3500 ST should be maintained with regular pressure checks, routine inspection for cuts, bulges, uneven wear, and sidewall damage, and close attention to any air loss. Because this is a heavy-duty truck, tire condition has to be viewed in relation to the loads and service the truck actually sees.
Longer-term care should also include watching for age-related deterioration, especially on trucks that sit for extended periods between use. Keeping the tires clean, properly inflated, and protected from prolonged exposure to harsh storage conditions can help preserve condition and make it easier to spot problems before a longer drive.
