2009 Dodge Trucks Ram 2500 ST Tires

The 2009 Dodge Trucks Ram 2500 ST uses a 245/70R17 radial tire. That is the primary size across the covered ST configurations, including 4x2 and 4x4 regular cab and quad cab models, so the search starts with one fitment rather than several different factory sizes.

That simplifies the first step, but the size alone is not the whole decision. A buyer should still confirm that the truck is using the correct 17-inch wheel setup and has not been changed to a different wheel or tire package over the years. Checking the existing wheel and tire markings before replacement helps avoid ordering the right size for the model but the wrong fitment for the truck in front of you.

The tire fitment for the 2009 Dodge Trucks Ram 2500 ST is built around a 17-inch rim. The 245/70R17 size uses that 17-inch wheel diameter, and the available product in this size is intended for rims measuring 6.5 to 8.0 inches in width.

Wheel diameter is the first number to confirm, but width matters too. A tire can share the proper 17-inch diameter and still be poorly matched if the wheel width falls outside the tire’s usable range. It is worth measuring or verifying the wheel before installation, especially on a truck that may have seen aftermarket wheels, replacement steel wheels, or service-use changes during its life.

The covered 2009 Dodge Trucks Ram 2500 ST sub-models use the same tire size: 245/70R17. That applies across the listed 4x2 and 4x4 regular cab and quad cab versions, so tire selection does not split into separate sizes by those ST configurations.

Even with shared fitment, it is still smart to confirm what is physically on the truck now. Heavy-duty pickups are often altered for work, towing, or appearance, and those changes can include different wheels or tires. Matching the new tire to the actual wheel diameter and width on the vehicle is the practical next step after confirming that the ST sub-model itself uses 245/70R17.

Start with the correct size, 245/70R17, and stay with radial construction. From there, compare the tire’s intended use, sidewall style, load specification, and wheel-width compatibility. For this Ram 2500 ST, the available product is a BFGoodrich All-Terrain T/A KO2 with a maximum load capacity of 3,000 lbs @ 80 psi and a 6.5- to 8.0-inch rim-width range.

The right choice depends on how the truck is actually used. A truck that sees jobsite travel, gravel roads, or mixed on-road and off-road driving may benefit from an all-terrain character, while appearance-conscious buyers may also care about the raised white letter presentation. Checking the wheel width and confirming that the truck’s use matches the tire’s load and service character is more important than choosing by size alone.

The available 245/70R17 product for the 2009 Dodge Trucks Ram 2500 ST uses an RWL sidewall, meaning raised white letters. That gives the tire a more traditional truck performance look than a plain blackwall and can make a visible difference in how the ST presents from the side.

Sidewall style does not change the basic fitment, but it does affect the truck’s appearance. Some owners want a more understated work-truck look, while others prefer the added visual detail of raised white lettering on a heavy-duty pickup. It is also worth checking how the tires are mounted, since an RWL tire can often be installed with the white-letter side facing in or out depending on the desired presentation.

The available tire option in the correct 245/70R17 size for the 2009 Dodge Trucks Ram 2500 ST comes from BFGoodrich. It is part of the All-Terrain T/A KO2 line, which places the selection focus on one recognized all-terrain truck tire rather than comparing several brands in this exact fitment listing.

That makes the buying process more about confirming specifications than sorting through a long brand list. A buyer should compare the wheel-width requirement, the 3,000 lbs @ 80 psi load figure, and the truck’s intended use before deciding. On a heavy-duty pickup, a single available brand option can still be the right one if its size, service character, and wheel compatibility match the truck’s real-world setup.

A period-style approach for a 2009 Dodge Trucks Ram 2500 ST starts with staying in the original fitment size, 245/70R17, and keeping the truck on a radial tire that suits its heavy-duty character. In this fitment, the available BFGoodrich All-Terrain T/A KO2 carries a truck-oriented all-terrain look rather than a passenger-car appearance.

For a clean, era-appropriate presentation, the goal is less about chasing restoration-era bias-ply cues and more about preserving the truck’s proper late-2000s stance and wheel relationship. Verifying the 17-inch wheel setup, avoiding unintended oversize substitutions, and choosing a sidewall treatment that matches the truck’s intended look will usually do more for appearance than changing to a different tire format.

On a 2009 Dodge Trucks Ram 2500 ST, radial construction is part of the truck’s proper visual and functional character. A 245/70R17 radial fills the wheel opening with the proportions expected for a modern heavy-duty pickup, so the construction type supports both the stance and the overall presentation.

Appearance is influenced by more than tread alone. The sidewall treatment, overall tire profile, and relationship to the factory wheel diameter all shape how finished the truck looks. Keeping the correct radial size and 17-inch wheel format usually preserves that visual balance, while off-size replacements can make a restored or well-kept ST look altered even before any difference is felt on the road.

Yes. A 2009 Dodge Trucks Ram 2500 ST may be designed around 245/70R17 tires, but wheel, suspension, and body changes can alter what actually clears and what matches the truck safely. Aftermarket wheels can change width or offset, and lift or leveling changes can affect how the tire sits during steering and suspension movement.

The practical step is to inspect the truck as it exists today, not only as it left the factory. Confirm the wheel diameter and width, look at inner-fender and steering clearance, and check whether the truck has been changed for towing, off-road use, or appearance. That matters even when staying with the original size, because modifications can change how much room the tire really has.

Before regular road use, inspect the wheels for damage, confirm that the tires match the truck’s required size, and make sure air pressure is set appropriately for the tire and intended load. It is also smart to look over the valve stems, lug hardware, and general condition of the suspension and steering components.

A heavy-duty truck puts real demands on its tires, so small issues become more important. Check for rubbing at full steering lock, make sure the tires seat properly on the wheels, and verify that there is no interference from worn suspension parts or prior modifications. A short test drive followed by another visual check can catch clearance or installation problems before the truck goes back into normal service.

Tires on a 2009 Dodge Trucks Ram 2500 ST should be inspected regularly, not only at replacement time. A visual check for uneven wear, cuts, punctures, sidewall damage, and air loss is worthwhile before longer trips and as part of routine service, especially on a truck that tows, hauls, or sits for periods between uses.

Inspection matters because a heavy-duty pickup can hide problems until load, heat, or road speed exposes them. Looking at tread wear can also reveal alignment or suspension issues before they become expensive. On a truck used intermittently, keeping an eye on aging and pressure loss is just as important as watching tread depth, since time and storage conditions can affect tires even when mileage stays low.
