The 2011 RAM Trucks 2500 sits in the heavy-duty pickup segment where towing, payload, and off-pavement capability all shape tire choice more than simple appearance alone. By this point, RAM had established the 2500 as a work-ready platform with distinct trim and drivetrain combinations, so exact fitment matters. This model uses 17-inch radial tire fitments, with 245/70R17, 265/70R17, and 285/70R17 appearing across different sub-models. Available choices center on BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls. The key step is matching the tire to the exact trim and wheel setup, then comparing load capacity, rim-width range, and intended truck use.
Which Tire Size Is Right for The 2011 RAM Trucks 2500
Three tire sizes apply to the 2011 RAM Trucks 2500, and the right one depends on the exact sub-model rather than a broad one-size-fits-all approach. All three are 17-inch metric radial fitments, so the main decision starts with identifying whether the truck is an ST, a Power Wagon, or another 2500 trim, then comparing load capacity and wheel-width compatibility within the correct size.
Fit(s): Big Horn 4x2, Big Horn 4x4, Laramie 4x2, Laramie 4x4, Laramie Longhorn 4x2, Laramie Longhorn 4x4, Outdoorsman 4x2, Outdoorsman 4x4, SLT 4x2, and SLT 4x4
Construction: Radial|Rim: 17 in
A 265/70R17 tire uses a 265-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2011 RAM Trucks 2500, this is the core fitment for many Big Horn, Laramie, Laramie Longhorn, Outdoorsman, and SLT configurations, making it the most broadly used size in the lineup. Available choices center on the BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls and differing load capacities. This size makes sense when the truck matches one of those sub-models and the wheel width falls within the tire’s intended range.
A 285/70R17 tire is wider than the 265 size, keeps the same 70-series profile concept, uses radial construction, and fits a 17-inch wheel. On the 2011 RAM Trucks 2500, this size is tied to the Power Wagon, so it should be treated as a configuration-specific fitment rather than a general 2500 size. BFGoodrich All-Terrain T/A KO2 options in this size are available with raised white letter styling and different load and service descriptions. This is the size to evaluate when the truck is a Power Wagon and the existing wheels match the tire’s rim-width range.
A 245/70R17 tire uses a 245-millimeter nominal section width, a 70-series profile, radial construction, and a 17-inch rim diameter. On the 2011 RAM Trucks 2500, this size is associated with ST 4x2 and ST 4x4 models, so it serves a specific place in the trim range rather than the full lineup. The available BFGoodrich All-Terrain T/A KO2 option carries raised white letter sidewalls and a load-oriented light-truck specification. This size is the one to compare when an ST model remains on its correct wheel setup and the goal is to stay with the proper trim-based fitment.
Sub-model fitment matters on the 2011 RAM Trucks 2500 because the lineup does not use one tire size across every trim. Most covered trims use 265/70R17, while ST models use 245/70R17 and the Power Wagon uses 285/70R17, so identifying the exact version of the truck comes first.

Tire Size & Fitment
What tire size fits a 2011 RAM Trucks 2500?
The 2011 RAM Trucks 2500 uses three trim-dependent tire sizes: 245/70R17, 265/70R17, and 285/70R17. ST 4x2 and ST 4x4 models use 245/70R17, the Power Wagon uses 285/70R17, and many other 2500 trims including Big Horn, Laramie, Laramie Longhorn, Outdoorsman, and SLT use 265/70R17.
That means the right answer starts with the truck’s exact sub-model, not just the model name alone. A 2500 that has changed wheels over time should also be checked for actual rim width and overall setup before replacing tires, especially on used heavy-duty trucks that may have been modified for towing, off-road use, or appearance.
What size rim does a 2011 RAM Trucks 2500 use?
The tire fitments covered for the 2011 RAM Trucks 2500 all use a 17-inch rim diameter. That includes 245/70R17, 265/70R17, and 285/70R17, so the final number in each size code matches a 17-inch wheel.
Rim diameter is only part of the wheel question on a heavy-duty pickup. Wheel width still matters, because the available tires have different approved width ranges depending on size, so the safest next step is to confirm the actual wheel dimensions on the truck before choosing among the available radial options.
Why does the 2011 RAM Trucks 2500 have more than one tire size?
The 2011 RAM Trucks 2500 has more than one tire size because fitment changes by sub-model. Most trims in this group use 265/70R17, ST models use 245/70R17, and the Power Wagon uses 285/70R17, even though all remain on 17-inch rims.
That difference matters because tire replacement is tied to how the truck was configured, not just to the 2500 badge. Once the exact trim is confirmed, the next practical checks are wheel width, the load specification of the replacement tire, and whether the truck still has its intended wheel-and-tire setup after years of service or ownership changes.
Choosing the Right Tire
What should I consider when choosing a tire for a 2011 RAM Trucks 2500?
Start with the correct size for the exact 2011 RAM Trucks 2500 sub-model, since this truck uses 245/70R17, 265/70R17, or 285/70R17 depending on trim. After that, compare the tire’s load capacity, rim-width range, and service description so the replacement matches how the truck is actually used.
A heavy-duty pickup can place very different demands on its tires depending on towing, payload, or off-pavement use. It helps to confirm the existing wheel dimensions and select a tire version that suits those needs without assuming every tire in the same basic size serves the truck in exactly the same way.
What sidewall styles are available for 2011 RAM Trucks 2500 tires?
The available tire choices for the 2011 RAM Trucks 2500 use an RWL sidewall, which is a raised white letter presentation. That styling appears across the applicable BFGoodrich All-Terrain T/A KO2 offerings in the covered 17-inch sizes.
Sidewall style mainly affects appearance, but it can still matter on a truck that doubles as both a work vehicle and a personal-use pickup. Since the available options share the same sidewall treatment, the more important comparison points become the correct trim-based size, the approved wheel-width range, and the load specification of the tire.
What brands offer tires for the 2011 RAM Trucks 2500?
The available products for the 2011 RAM Trucks 2500 are from BFGoodrich. The current fitments shown across 245/70R17, 265/70R17, and 285/70R17 center on the All-Terrain T/A KO2 series.
Since the product grid is focused on one brand and one tire family, the real comparison is within the individual size and specification rather than between competing brand names. That makes it especially useful to look at load capacity, wheel-width range, and the exact sub-model fitment before settling on a tire for the truck.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 RAM Trucks 2500?
Yes, modifications can affect tire fitment on a 2011 RAM Trucks 2500 even when the truck still appears to use the same 17-inch wheel diameter. Changes such as aftermarket wheels, altered wheel width, different offset, suspension lifts, or leveling kits can all change how a 245/70R17, 265/70R17, or 285/70R17 tire sits in the wheel opening.
That is especially important on a used heavy-duty truck, where prior owners may have changed parts for towing, off-road use, or appearance. A quick check of wheel dimensions, steering clearance, and tire-to-fender or tire-to-suspension space can prevent choosing a size that matches the trim on paper but not the truck’s current setup.
What should I inspect before driving a 2011 RAM Trucks 2500 on new tires?
Before putting a 2011 RAM Trucks 2500 into regular road use on new tires, inspect wheel condition, valve stems, lug hardware, and inflation pressure, then make sure the replacement size matches the truck’s exact sub-model. It also helps to confirm that tread sits evenly and the tires clear suspension and body components through normal steering travel.
A heavy-duty pickup deserves a little extra attention because load and service demands can expose setup problems quickly. Checking alignment condition, looking for suspension wear, and rechecking pressure after the first miles can help the new tires wear evenly and perform as intended for the truck’s real-world use.
How often should tires on a 2011 RAM Trucks 2500 be inspected?
Tires on a 2011 RAM Trucks 2500 should be inspected regularly, especially before towing, hauling, or taking a longer trip. Look for uneven tread wear, cuts, sidewall cracking, bulges, punctures, and any sign of slow air loss, because heavy-duty truck use can magnify problems that seem minor at first glance.
A practical routine is to check pressure and visible condition often, then give the tires a more complete inspection whenever the truck is serviced or rotated. That habit is useful whether the truck sees daily work or occasional use, since long periods of sitting can be just as hard on tire condition as frequent mileage.
