The 2011 RAM Trucks 1500 sits in an era when full-size pickups were expected to balance work capability, everyday comfort, and a more personalized trim lineup than earlier generations. That matters for tire selection because this truck was offered with several distinct radial fitments, including 265/70R17, 275/70R17, 275/60R20, and 285/45R22 depending on trim and wheel package. The real decision is not simply finding a tire for a RAM 1500, but matching the exact sub-model and wheel diameter first. Once that is confirmed, the focus shifts to the tire's intended use, whether that means stock-style road use, a more truck-oriented stance, or evaluating available sidewall and load-spec choices.
Which Tire Size Is Right for The 2011 RAM Trucks 1500
The 2011 RAM Trucks 1500 uses four primary tire sizes, and they do not apply across every sub-model in the same way. Fitment varies by trim and wheel package, with 17-inch, 20-inch, and 22-inch rim diameters in use, so the first step is confirming the exact sub-model and the actual wheels on the truck before comparing tires.
Fit(s): Big Horn, Laramie, Laramie Longhorn, Outdoorsman (20 Inch Option), SLT (20 Inch Option), and Sport
Construction: Radial|Rim: 20 in
275/60R20 is a metric radial size in which 275 is the nominal section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 20 is the rim diameter in inches. On the 2011 RAM Trucks 1500, this size is tied to specific trims and 20-inch wheel packages rather than every configuration. It is a useful fitment to verify carefully because several sub-models could be equipped with it, while others used 17-inch or 22-inch setups instead. Buyers considering this size should confirm the truck's wheel diameter before moving on to tread style or intended use.
Fit(s): Laramie, Laramie Longhorn, SLT, ST, and Tradesman
Construction: Radial|Rim: 17 in
265/70R17 is a metric radial size with a 265-millimeter nominal section width, a 70-series profile, radial construction, and a 17-inch rim diameter. This is one of the key 17-inch fitments for the 2011 RAM Trucks 1500 and appears on several sub-models, making it a common starting point for stock-wheel trucks. Available product choice in this size includes BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls and differing load specifications. It is a size worth comparing closely if the truck sees mixed road use or if load rating matters as much as appearance.
275/70R17 follows the same metric radial format, with a 275-millimeter nominal section width, a 70-series profile, and fitment on a 17-inch wheel. For the 2011 RAM Trucks 1500, this size is associated with a specific sub-model rather than the broader lineup, so it should not be treated as universal across all trims. Its role is important because it separates one 17-inch setup from another and can affect how the truck sits and how replacement choices are evaluated. The safest approach is to confirm both the sub-model and the wheel package before choosing a replacement tire.
285/45R22 is a metric radial size that uses a 285-millimeter nominal section width, a lower 45-series profile, and a 22-inch rim diameter. On the 2011 RAM Trucks 1500, this fitment is tied to a specific trim package and stands apart from the 17-inch and 20-inch alternatives used elsewhere in the range. Its lower-profile format makes wheel confirmation especially important because a truck equipped with 22-inch wheels is on a different replacement path than one running 17-inch or 20-inch wheels. This is the size to verify carefully before comparing style, load specification, or intended driving use.
Tire fitment on the 2011 RAM Trucks 1500 varies by sub-model and, in several cases, by wheel option within the same trim. Checking the exact trim name matters here because a 17-inch setup, a 20-inch option package, and the 22-inch Sport R/T configuration do not follow the same replacement path.

2011 RAM Trucks 1500 Big Horn
The 2011 RAM Trucks 1500 Big Horn uses the 275/60R20 radial fitment. That makes wheel-diameter confirmation straightforward, and the next step is choosing a tire that suits how the truck is actually driven rather than assuming a 17-inch RAM 1500 tire will cross over.
The 2011 RAM Trucks 1500 Laramie can use either a 265/70R17 radial or a 275/60R20 radial depending on wheel setup. Tire selection starts with confirming whether the truck is on 17-inch or 20-inch wheels, since that determines the correct size before any brand or use-based comparison begins.
The 2011 RAM Trucks 1500 Laramie Longhorn also spans two fitments, 265/70R17 and 275/60R20, tied to different wheel configurations. That means the sub-model name alone is not enough; the actual wheel diameter on the truck should be checked before choosing a replacement tire.
The 2011 RAM Trucks 1500 Outdoorsman uses the 275/70R17 radial size in its standard form. This is a distinct 17-inch fitment within the lineup, so replacement shopping should stay centered on that exact size rather than the other 17-inch or 20-inch alternatives used on different trims.
The 2011 RAM Trucks 1500 Outdoorsman (20 Inch Option) moves to the 275/60R20 radial fitment. The important takeaway is that the Outdoorsman name appears with more than one wheel setup, so confirming the optioned wheel diameter prevents choosing a tire meant for the standard 17-inch version.
The 2011 RAM Trucks 1500 SLT uses the 265/70R17 radial size in its standard configuration. That keeps tire selection centered on a 17-inch wheel package, with the practical follow-up being a comparison of available load specification, sidewall presentation, and intended driving use.
The 2011 RAM Trucks 1500 SLT (20 Inch Option) uses 275/60R20 rather than the standard SLT's 17-inch fitment. This is a good example of why wheel-package confirmation matters on this truck, since the trim name is similar but the replacement tire size is not.
The 2011 RAM Trucks 1500 ST uses the 265/70R17 radial fitment. For this sub-model, the tire decision is less about multiple factory size paths and more about choosing the right 17-inch tire characteristics for the truck's real-world use.
The 2011 RAM Trucks 1500 Sport uses the 275/60R20 radial size. That places it on a 20-inch replacement path, so buyers should verify that the truck still wears its intended wheel diameter before comparing tire options or considering any modified setup.
The 2011 RAM Trucks 1500 Sport R/T uses the 285/45R22 radial fitment. Its 22-inch wheel setup separates it clearly from the rest of the lineup, making wheel confirmation the first priority before evaluating any replacement tire in this lower-profile size.
The 2011 RAM Trucks 1500 Tradesman uses the 265/70R17 radial size. That makes it part of the 17-inch fitment group, where the buyer's attention can shift from basic size matching to load specification, tread purpose, and compatibility with the truck's actual wheels.
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.

Tire Size & Fitment
What tire size fits a 2011 RAM Trucks 1500?
The 2011 RAM Trucks 1500 uses four primary tire sizes: 265/70R17, 275/70R17, 275/60R20, and 285/45R22. All are radial sizes, but they do not apply across the full lineup in the same way, because trim level and wheel package determine which one belongs on a particular truck.
The practical first step is matching the truck's exact sub-model and wheel diameter before comparing tires. A Laramie or SLT can follow more than one fitment path, while trims such as the Sport R/T are tied to a distinct 22-inch setup, so checking the actual wheels on the truck prevents an incorrect starting point.
What size rim does a 2011 RAM Trucks 1500 use?
A 2011 RAM Trucks 1500 can use 17-inch, 20-inch, or 22-inch rims depending on sub-model and wheel option. The 265/70R17 and 275/70R17 sizes use 17-inch rims, 275/60R20 uses a 20-inch rim, and 285/45R22 uses a 22-inch rim.
Wheel diameter is the most important thing to confirm before buying tires for this truck. Similar-looking trims can use different rim sizes, and option-package versions such as 20-inch SLT or Outdoorsman models follow a different fitment path than their standard 17-inch counterparts.
Why does the 2011 RAM Trucks 1500 have more than one tire size?
The 2011 RAM Trucks 1500 spans a broad trim range, and that creates multiple factory fitment paths. Some versions use 17-inch wheels, others use 20-inch wheels, and the Sport R/T uses a 22-inch wheel, so more than one tire size is part of the lineup by design.
That means the right replacement tire depends on more than the model name alone. The buyer should confirm the exact sub-model and check the actual wheel diameter on the truck, especially if it has changed hands before or could have been fitted with different wheels at some point.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2011 RAM Trucks 1500?
Start with the basic fitment points: the truck must be one of the 2011 RAM Trucks 1500 sub-models that uses 265/70R17, and it must still be on 17-inch wheels. In this size, BFGoodrich All-Terrain T/A KO2 choices are available with raised white letter sidewalls and different load specifications.
From there, compare the tire's intended use with how the truck is actually driven. Rim-width compatibility, sidewall presentation, load capacity, and overall tire weight can all influence the final choice, particularly on a pickup that may alternate between everyday street use, cargo duty, and more rugged driving conditions.
What sidewall styles are available for 2011 RAM Trucks 1500 tires?
Within the available product selection shown for this vehicle, 265/70R17 appears with an RWL sidewall, which is a raised white letter presentation. That gives this size a more truck-oriented visual character than a plain blackwall tire would, while still remaining within the correct fitment family for the applicable sub-models.
Sidewall style should be chosen after the size and wheel diameter are confirmed. Appearance matters, but it should come after the more important checks for trim-specific fitment, rim compatibility, and the load specification that best matches how the RAM 1500 is driven and used.
What brands offer tires for the 2011 RAM Trucks 1500?
The available product selection shown here includes BFGoodrich in 265/70R17, specifically within the All-Terrain T/A KO2 series. That means buyers shopping this size can compare more than one load specification within the same brand and series rather than choosing blindly by size alone.
Brand is only one part of the decision on a 2011 RAM Trucks 1500. It still makes sense to confirm that the truck uses 265/70R17, review the 17-inch wheel setup, and then compare details such as load capacity, tire weight, sidewall style, and the truck's intended mix of road and utility use.
Restoration & Appearance
Which tire should I choose for a period-style 2011 RAM Trucks 1500?
A period-style choice for a 2011 RAM Trucks 1500 starts with staying in the correct original fitment family for the truck's exact trim and wheel package, whether that is 265/70R17, 275/70R17, 275/60R20, or 285/45R22. For applicable 265/70R17 trucks, the BFGoodrich All-Terrain T/A KO2 presents a distinctly truck-oriented look.
The visual result should still be balanced against how closely the truck is being kept to its original wheel setup. If appearance accuracy matters at a higher level, confirm the actual wheel package and compare surviving vehicle documentation or marque-specific references before choosing a sidewall or tread presentation purely on style.
How does tire construction affect the appearance of a restored 2011 RAM Trucks 1500?
On the 2011 RAM Trucks 1500, the primary fitments are radial across the lineup, so maintaining the correct radial size already preserves the basic visual proportion intended for the truck's wheel package. Construction is less a bias-ply-versus-radial question here and more a matter of keeping the right size and profile for the trim.
Appearance changes more noticeably when wheel diameter, sidewall height, or sidewall treatment changes. A 17-inch truck, a 20-inch option package, and the 22-inch Sport R/T each have a different visual stance, so restoring the proper look starts with matching the correct fitment path before comparing tread or lettering style.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2011 RAM Trucks 1500?
Yes. A 2011 RAM Trucks 1500 that has aftermarket wheels, suspension changes, leveling or lowering parts, or altered ride height may no longer follow its original trim-based tire path as cleanly as a stock truck. That is especially important on a model range that already spans 17-inch, 20-inch, and 22-inch wheel diameters.
The safest approach is to verify the actual wheel diameter and width on the truck, then check steering and body clearance before choosing tires. Even when the size sounds close to an original fitment, wheel changes and suspension alterations can shift the clearance picture enough to make careful measurement worthwhile.
What should I inspect before driving a 2011 RAM Trucks 1500 on new tires?
Before regular road use, inspect the wheels for damage, confirm the tire size matches the truck's trim and wheel package, and make sure each tire is mounted correctly and holding air consistently. It also helps to look over the suspension and steering components so the new tires are not asked to work around worn hardware.
A quick follow-up check after the first miles is just as useful. Recheck inflation, watch for any rubbing at full steering lock or over suspension movement, and pay attention to vibration or pull, since early signs like these can point to a wheel, alignment, or fitment issue worth correcting promptly.
How often should tires on a 2011 RAM Trucks 1500 be inspected?
Tires on a 2011 RAM Trucks 1500 should be inspected regularly rather than only at replacement time. A visual check for uneven wear, cuts, bulges, cracking, embedded debris, and slow air loss can catch issues early, especially on a truck that sees changing loads or a mix of highway and rougher surface use.
Routine inspection becomes even more important if the truck is driven infrequently or sits for stretches between outings. Pressure changes, aging, and unnoticed damage can develop while the truck is parked, so giving the tires a close look before longer drives is a sensible habit.
