RAM Trucks 3500 ST Tires
RAM Trucks 3500 ST is a heavy-duty pickup from the early 2010s, built for buyers who needed serious payload and towing capability rather than light-duty everyday use. Across the 2011 to 2013 model years, RAM Trucks 3500 ST sat in a part of the truck market where wheel, tire, and load-rating choices mattered because they directly affected how the truck was equipped for work. Tire selection is not entirely straightforward here because the model uses more than one size during its run, and 2013 introduces an 18-inch fitment alongside the 17-inch sizes used earlier. The first thing to confirm on any RAM Trucks 3500 ST is whether the truck carries 17-inch or 18-inch wheels.
RAM Trucks 3500 ST Tire Size Guide
RAM Trucks 3500 ST uses 3 distinct tire sizes across the 2011 to 2013 model years, and the rim diameter changes during production from 17-inch to 18-inch in 2013. All three sizes use modern metric radial sizing, where the first number is section width in millimeters, the second is aspect ratio, and the final number is wheel diameter in inches. That means year alone is not enough here, because 2013 includes both a 17-inch and an 18-inch fitment.
265/70R17 fits RAM Trucks 3500 ST in 2011 and 2012 and is one of the two sizes used in those years. The size code indicates a 265 mm section width, a 70-series aspect ratio, radial construction, and a 17-inch rim diameter. Choose this size if the truck is equipped with 17-inch wheels and the wider of the two 2011-2012 fitments, and verify the load rating on the tire matches the truck's intended use.
235/80R17 fits RAM Trucks 3500 ST from 2011 through 2013 and is the only size that spans the full model run shown here. The size code indicates a 235 mm section width, an 80-series aspect ratio, radial construction, and a 17-inch rim diameter. Choose this size if the truck carries 17-inch wheels and calls for the narrower, taller-profile fitment rather than the wider 265-section option.
275/70R18 fits RAM Trucks 3500 ST in 2013 and represents the 18-inch fitment introduced during this model span. The size code indicates a 275 mm section width, a 70-series aspect ratio, radial construction, and an 18-inch rim diameter. Choose this size only on trucks already equipped with 18-inch wheels, because it is not interchangeable with the 17-inch options without a wheel change.
If you have a 2013 RAM Trucks 3500 ST, identify the specific configuration before selecting a tire because that year includes both 17-inch and 18-inch fitments.

Frequently Asked Questions
The FAQ below focuses on the real decision points for RAM Trucks 3500 ST owners: which of the three sizes fits a specific year, how the 17-inch and 18-inch wheel difference affects selection, and what to verify about load rating, sidewall style, and long-term tire care.
Size Basics & Fitment
RAM Trucks 3500 ST uses three tire sizes across the 2011 to 2013 model years: 265/70R17 for 2011-2012, 235/80R17 for 2011-2013, and 275/70R18 for 2013. The 265/70R17 and 235/80R17 sizes both mount on 17-inch wheels, while 275/70R18 mounts on an 18-inch wheel. All of the available products shown for RAM Trucks 3500 ST are radial tires.
The practical step is to match the tire size to the actual wheel diameter on the truck first, then confirm the specific size listed for that year and configuration. A 2011 or 2012 RAM Trucks 3500 ST may use one of two 17-inch sizes, while a 2013 truck may still be on 17-inch wheels or may have the 18-inch fitment instead.
A 2013 RAM Trucks 3500 ST can use either 235/80R17 or 275/70R18, which means the split is tied to wheel diameter rather than a simple year break. One fitment uses a 17-inch wheel and the other uses an 18-inch wheel. Both are radial sizes, but they are not interchangeable on the same wheel.
That makes the wheel itself the deciding factor on a 2013 truck. Before replacing tires on a 2013 RAM Trucks 3500 ST, check the sidewall of the existing tire or measure the wheel diameter so you do not accidentally choose an 18-inch tire for a 17-inch wheel, or the reverse.
RAM Trucks 3500 ST uses both 17-inch and 18-inch rim diameters in the 2011 to 2013 range covered here. The 17-inch wheel is used with 265/70R17 in 2011-2012 and with 235/80R17 in 2011-2013, while the 18-inch wheel appears with 275/70R18 in 2013. The change to an 18-inch fitment first appears in 2013.
Rim diameter is the first fitment detail to verify because the tire must match the wheel exactly. If you are working with a RAM Trucks 3500 ST that has changed hands, been upfitted, or had wheel swaps over time, treat the current wheel diameter as the final authority before choosing among the listed sizes.
Buying the Right Tire
Start with the model year, then narrow it by wheel diameter and the size already fitted to the truck. A 2011 or 2012 RAM Trucks 3500 ST uses either 265/70R17 or 235/80R17, while a 2013 RAM Trucks 3500 ST uses either 235/80R17 or 275/70R18. That means the year gets you close, but the actual wheel and tire markings finish the identification.
Look at the current sidewall, the wheel diameter, and the truck's existing setup before deciding between the listed options. On a heavy-duty pickup like RAM Trucks 3500 ST, it also makes sense to compare the load rating of the replacement tire with the truck's work duties so the tire choice matches how the truck is actually used.
RAM Trucks 3500 ST tires in the available products come in both RWL and RBL sidewall styles. The 265/70R17 and 275/70R18 products are listed with RWL sidewalls, while the 235/80R17 product is listed with an RBL sidewall. All of them are BFGoodrich All-Terrain T/A KO2 radial tires.
Sidewall style matters mostly for appearance if the size and load requirements are already correct. If you are trying to keep a RAM Trucks 3500 ST looking close to its existing setup, compare the current tire's sidewall treatment before changing from raised white letters to a black sidewall, or the other way around.
The available RAM Trucks 3500 ST products shown here come from one brand: BFGoodrich. All four listed products are part of the BFGoodrich All-Terrain T/A KO2 series, covering 265/70R17, 235/80R17, and 275/70R18 sizes. The available selection is therefore centered on one modern radial all-terrain family rather than multiple competing brands.
That simplifies the decision because your main variables are size, wheel diameter, sidewall style, and load rating rather than brand-to-brand differences. If you are replacing a single damaged tire on a RAM Trucks 3500 ST, also compare the exact size and service description on the existing tire so the replacement matches the rest of the set as closely as possible.
Maintenance & Longevity
A RAM Trucks 3500 ST should be stored on a clean, dry surface away from direct sunlight, ozone sources, and large temperature swings. Heavy-duty tires age from time, heat, and load exposure even when the truck is not driven often. Keeping the truck clean and the tires properly inflated helps prevent flat-spotting and sidewall stress during long storage periods.
If the truck will sit for an extended time, move it occasionally so the same footprint is not carrying the weight month after month. Owners who keep a RAM Trucks 3500 ST for seasonal towing, collector use, or occasional hauling should make tire care part of storage planning rather than waiting until the next driving season.
Tires on a RAM Trucks 3500 ST should be inspected regularly, with a close visual check before road trips, towing duty, or long periods of highway use. Look for uneven wear, weather checking, cuts, punctures, bulges, and signs that inflation has been running too low or too high. Because RAM Trucks 3500 ST is a heavy-duty truck, irregular wear can show up quickly if alignment, loading, or pressure is off.
A monthly inspection routine is sensible even when the truck is driven infrequently. If a RAM Trucks 3500 ST spends much of its time parked, inspection becomes even more important because aging, cracking, and pressure loss can develop quietly without the miles that would normally draw your attention to a problem.
Tires on a RAM Trucks 3500 ST should be replaced when age, cracking, impact damage, irregular wear, or casing deterioration makes them questionable, even if the tread still looks usable. Tread depth is only one part of the condition picture. On a heavy-duty truck, a tire that appears acceptable at a glance may still be too old or too compromised for safe service under load.
That is especially important if the truck tows, hauls, or spends time at highway speed, because those uses place more stress on an aging tire. If there is any doubt about the condition of a RAM Trucks 3500 ST tire, have it evaluated by a tire professional and treat visible age cracking or structural damage as a prompt to replace the tire rather than continue using it.
Restoration & Authenticity
RAM Trucks 3500 ST used 265/70R17 and 235/80R17 in 2011-2012, with 235/80R17 and 275/70R18 appearing in 2013. The available products shown here are BFGoodrich All-Terrain T/A KO2 radials, but that does not mean every RAM Trucks 3500 ST left the factory on that exact tire. What can be said with confidence is which sizes correspond to the covered years.
If originality matters, use the size range as the starting point and then compare against the truck's original labels, build information, or marque-specific references. On a later heavy-duty truck like RAM Trucks 3500 ST, getting the correct wheel diameter and service description usually matters more in practical terms than chasing a specific replacement brand.
Correct tire fitment can affect how a RAM Trucks 3500 ST is viewed, especially if the truck is being preserved in a factory-style presentation. The right size and wheel diameter help maintain the intended stance and appearance, while an obviously incorrect fitment can stand out immediately. On a work-oriented truck, proper load-rated fitment also signals that the vehicle has been maintained with mechanical sense.
For owners concerned with show presentation or resale credibility, the safest approach is to keep the truck on one of the size combinations used for its year and wheel setup. If the truck has been modified over time, save any original wheel and tire information you can verify so future corrections are easier and better supported.
RAM Trucks 3500 ST tire options here include both RWL and RBL sidewall styles. RWL appears on the 265/70R17 and 275/70R18 products, while RBL appears on the 235/80R17 product. That means sidewall appearance can vary with the size you are using, not just with personal taste.
If the goal is a tidy, factory-like look, compare the replacement tire to the truck's current presentation and period photos of similarly equipped trucks. A RAM Trucks 3500 ST restored as a straightforward work truck may look more natural with black sidewalls, while a truck already carrying raised white letters may benefit from staying visually consistent.
Safety & Road Use
The listed RAM Trucks 3500 ST tires are modern radial truck tires, which makes them suitable in principle for normal public-road use when they are the correct size for the wheel and are in sound condition. Safety still depends on age, inflation, load rating, tread condition, and whether the tire matches the truck's actual wheel diameter. A 17-inch tire on an 18-inch wheel, or the reverse, is never an acceptable substitute.
Before regular road use, make sure the RAM Trucks 3500 ST has a matched set appropriate for its duties and that each tire is inflated for the way the truck is being used. Heavy-duty pickups ask more of their tires than light commuters do, so condition and load capacity deserve as much attention as basic size.
Before driving a RAM Trucks 3500 ST, check tire pressure, visible condition, tread wear, and the size marking on each tire. Make sure all four tires match the wheel diameter the truck actually carries, especially on 2013 models where both 17-inch and 18-inch fitments appear. Also look for cuts, bulges, cracking, or signs of uneven wear that could point to alignment or loading issues.
That quick inspection matters even more before towing, hauling, or long highway drives. A RAM Trucks 3500 ST may spend part of its life parked and part of it working hard, so a habit of checking the tires before use can catch problems early and prevent a minor condition issue from turning into a roadside failure.
A RAM Trucks 3500 ST should always be driven within the capability of the exact tires fitted, including their service description, condition, and inflation. The listed products include service descriptions such as 112S, 121S, 120S, and 125/122R, which indicate that speed capability varies by the specific tire. Real-world safe speed is therefore determined by the actual tire on the truck, not just by the model name.
For practical use, keep a RAM Trucks 3500 ST at sensible speeds for a loaded heavy-duty pickup and avoid pushing an older or questionable tire to sustained high-speed operation. If the truck is used for towing or hauling, proper pressure and condition become just as important as the letter in the speed rating.
