The 2009 Dodge Trucks Ram 1500 ST comes from a period when full-size pickups were expected to balance everyday work, highway comfort, and light off-road use in one package. In ST trim, the Ram 1500 still centers the tire decision on practical fitment rather than vintage-style restoration concerns. This truck uses a 265/70R17 radial tire on a 17-inch rim, giving owners one clear primary size to work from across the covered ST configurations. Available choices in that size focus on all-terrain radial construction with raised white letter sidewalls. The real decision is matching load rating, wheel compatibility, and intended use to the truck’s actual cab and drivetrain setup.
Which Tire Size Is Right for The 2009 Dodge Trucks Ram 1500 ST
The 2009 Dodge Trucks Ram 1500 ST uses one primary tire size: 265/70R17, and it is a radial fitment on a 17-inch rim. That same size is used across the covered ST sub-models, so the main choice is not between different factory fitments, but between available product specifications such as load capacity, sidewall presentation, and how the tire suits the truck’s intended use.
A 265/70R17 size uses a 265-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2009 Dodge Trucks Ram 1500 ST, this modern metric radial format suits a truck that may see daily driving, light hauling, or mixed on-road and unpaved use. Available choices in this size include BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls and different load ratings. Selecting within this size means confirming the truck’s actual wheel width, expected load demands, and whether the current setup remains stock.
Tire fitment is straightforward across the covered 2009 Dodge Trucks Ram 1500 ST sub-models because they all use the same primary tire size. Checking the exact sub-model still matters when reviewing wheel setup, ride height, and how the truck will actually be used.

2009 Dodge Trucks Ram 1500 ST 4x2 Quad Cab
The 2009 Dodge Trucks Ram 1500 ST 4x2 Quad Cab uses the same 265/70R17 radial fitment as the other covered ST configurations. That keeps size selection simple, so attention can shift to wheel-width compatibility, load rating, and whether an all-terrain tread matches the truck’s street or mixed-use role.
The 2009 Dodge Trucks Ram 1500 ST 4x2 Reg. Cab also uses 265/70R17 radial tires on a 17-inch rim. Since the primary size does not change, the important comparison is between available product specifications and whether the truck still has its original wheel and suspension arrangement.
The 2009 Dodge Trucks Ram 1500 ST 4x4 Quad Cab keeps the same 265/70R17 radial tire size as the rest of the covered ST range. For this sub-model, the buying decision is mainly about choosing the right load capacity and checking clearance if aftermarket wheels, suspension changes, or off-road use are part of the truck’s current setup.
The 2009 Dodge Trucks Ram 1500 ST 4x4 Reg. Cab shares the 265/70R17 radial fitment used across the covered ST sub-models. That consistency makes the main decision a product-level one, especially if the truck is used for work duty, sees rougher surfaces, or has had changes to wheels or ride height.
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 2009 Dodge Trucks Ram 1500 ST?
The 2009 Dodge Trucks Ram 1500 ST uses a 265/70R17 radial tire. That size appears across the covered ST configurations, including 4x2 and 4x4 regular cab and quad cab models, so the primary fitment question is straightforward for this truck.
A single size does not remove the need to verify the truck’s actual setup. Check that the wheels are still 17-inch rims, confirm the wheel width falls within the tire’s approved range, and look for any suspension, lift, or wheel changes that could affect clearance or change what works best for the truck.
What size rim does a 2009 Dodge Trucks Ram 1500 ST use?
The 2009 Dodge Trucks Ram 1500 ST uses a 17-inch rim with its 265/70R17 tire size. Available tires in this fitment are built for that 17-inch diameter, and the product options in this size call for wheel widths in the 7.0-inch to 9.0-inch range.
Rim diameter is the first number to confirm because a 17-inch tire cannot be mounted on a wheel of another diameter. Width matters too, especially on a truck that may carry loads or use aftermarket wheels, so it is worth checking the stamp on the wheel or measuring before choosing between available tire specifications.
Do all 2009 Dodge Trucks Ram 1500 ST sub-models use the same tire size?
Yes. The covered 2009 Dodge Trucks Ram 1500 ST sub-models all use the same 265/70R17 radial tire size. That includes 4x2 Quad Cab, 4x2 Reg. Cab, 4x4 Quad Cab, and 4x4 Reg. Cab configurations, so there is no separate primary size split within those ST versions.
Shared size fitment makes replacement easier, but it does not mean every truck is configured the same today. A used Ram may have different wheels, altered ride height, or a work-focused setup that changes the best product choice, so check wheel dimensions and intended load use before settling on a specific 265/70R17 tire.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2009 Dodge Trucks Ram 1500 ST?
Start with the correct 265/70R17 size and confirm that the truck still uses 17-inch wheels in the proper width range. From there, compare the available tire’s load specification, inflation-related load rating, weight, and tread character to how the Ram 1500 ST is actually driven and loaded.
A truck used mainly on pavement may prioritize one set of tradeoffs, while one that sees rough roads, cargo, or trail access may need a heavier-duty specification. It also helps to confirm whether the truck remains stock, because wheel changes, suspension alterations, and added accessories can all influence what tire choice makes the most sense.
What sidewall styles are available for 2009 Dodge Trucks Ram 1500 ST tires?
The available 265/70R17 tires for the 2009 Dodge Trucks Ram 1500 ST use an RWL sidewall style, which means raised white letters. That gives the truck a more traditional light-truck appearance than a plain blackwall and is often part of the visual appeal of all-terrain tires.
Sidewall style is mostly an appearance decision unless the truck has a specific look you want to preserve. The more important functional checks remain the correct size, wheel compatibility, and the tire’s load specification, but sidewall presentation can still matter if the Ram is being kept as a clean street truck or a more rugged-looking daily driver.
What tire series are available for the 2009 Dodge Trucks Ram 1500 ST?
The available tire series in the 265/70R17 fitment for the 2009 Dodge Trucks Ram 1500 ST is the BFGoodrich All-Terrain T/A KO2. Within that series, the main distinction is not a different sidewall family or construction type, but different load-rated versions of the same size.
That means the buying decision is less about switching between multiple styling themes and more about matching specification to use. A lightly used street truck and a Ram that carries more weight or sees tougher service can require different load capacities, so compare the tire details carefully instead of choosing only by tread name.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Dodge Trucks Ram 1500 ST?
Yes. Even though the covered 2009 Dodge Trucks Ram 1500 ST fitment is 265/70R17, modifications can change whether a particular tire and wheel combination works as expected. Aftermarket wheels, different offsets, lift kits, leveling kits, or altered suspension parts can all affect clearance and overall compatibility.
A truck can still wear the same size on paper and behave differently in the wheelwell once its setup changes. It is smart to inspect steering clearance, fender clearance, and wheel width before replacing tires, especially if the Ram was modified by a previous owner or is used in conditions that push suspension travel more than normal.
What should I inspect before driving a 2009 Dodge Trucks Ram 1500 ST on new tires?
Check that each tire is the correct 265/70R17 size, mounted on the proper 17-inch wheel, and inflated appropriately for the truck’s use. Inspect the wheels for damage, make sure the tires seat evenly, and look for any rubbing points around suspension parts, inner liners, and fender edges before regular driving begins.
A short test drive followed by a second visual inspection can catch issues early. Pay attention to vibration, pull, unusual noise, or fresh contact marks, and confirm lug hardware is secure. On a truck, it also helps to think about expected load use right away, because cargo and towing demands can reveal fitment or inflation problems quickly.
How should 265/70R17 tires on a 2009 Dodge Trucks Ram 1500 ST be maintained?
Maintain 265/70R17 tires on a 2009 Dodge Trucks Ram 1500 ST by checking pressure regularly, watching for uneven tread wear, and inspecting the sidewalls for cuts, cracking, or bulges. A truck tire should also be checked for slow air loss and damage from curbs, gravel, potholes, or heavier-use conditions.
Consistent inspection matters because pickup tires often see more varied duty than passenger-car tires. Rotation and alignment checks can help control irregular wear, while storage and downtime still matter if the truck is not driven often. Keeping the wheels clean and monitoring tread condition will make it easier to spot developing issues before they affect road use.
