The 2006 Dodge Trucks Ram 2500 ST sits in the heavy-duty pickup segment where tire choice matters for more than appearance alone. Whether the truck is used for work, towing, or maintained as a clean early-2000s Ram, the right tire needs to match the truck’s wheel setup and intended use. This Ram 2500 ST uses a 245/70R17 radial tire on a 17-inch rim across its covered configurations. In this size, the available option carries an all-terrain character with raised white letter styling. The real decision is less about sorting through multiple factory sizes and more about choosing the right tread personality, wheel compatibility, and road-use setup for the truck you have.
Which Tire Size Is Right for The 2006 Dodge Trucks Ram 2500 ST
The 2006 Dodge Trucks Ram 2500 ST uses one primary tire size: 245/70R17, a radial tire for a 17-inch rim. That fitment stays consistent across the covered ST sub-models, so the main decision is choosing the right tire within that size and confirming that the truck still has the correct wheel width and overall setup if anything has been changed over the years.
A 245/70R17 tire uses a 245-millimeter nominal section width, a 70-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2006 Dodge Trucks Ram 2500 ST, this is the core fitment and suits a heavy-duty pickup that may see a mix of pavement use, hauling, and general truck duty. The available tire in this size is a BFGoodrich All-Terrain T/A KO2 with raised white letter styling, giving the truck a more assertive presentation than a plain blackwall. This size makes sense when the goal is to stay with the correct basic fitment while comparing tread style, rim-width compatibility, and intended use.
Tire fitment is straightforward across the covered 2006 Dodge Trucks Ram 2500 ST sub-models, with the same 245/70R17 radial size used throughout. Checking the exact cab and driveline still helps confirm that the truck remains on its intended wheel and tire setup, especially if it has been modified.

2006 Dodge Trucks Ram 2500 ST 4x2 Quad Cab
The 2006 Dodge Trucks Ram 2500 ST 4x2 Quad Cab uses the same 245/70R17 radial fitment as the other covered ST configurations. That keeps tire selection focused on choosing the right product in the correct size and confirming wheel width and overall truck setup before replacement.
The 2006 Dodge Trucks Ram 2500 ST 4x2 Reg. Cab also uses 245/70R17 radial tires. For this configuration, the main question is not which size fits, but whether the wheel and tire package still matches stock-style dimensions after years of use, service, or aftermarket changes.
The 2006 Dodge Trucks Ram 2500 ST 4x4 Quad Cab stays with the same 245/70R17 radial size. Tire choice here comes down to selecting the right tread and sidewall presentation in that fitment while checking clearance, especially if the truck has seen suspension or wheel changes.
The 2006 Dodge Trucks Ram 2500 ST 4x4 Reg. Cab uses 245/70R17 radials as well. That consistency simplifies replacement, but it is still worth verifying the actual wheel dimensions and the truck’s current stance before choosing a new tire for regular road or work use.
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.

Owners of a 2006 Dodge Trucks Ram 2500 ST usually need clear answers on size, 17-inch rim fitment, product selection, modifications, and road-use checks. These FAQs focus on the practical tire questions that come up when replacing or evaluating 245/70R17 tires on this truck.
Tire Size & Fitment
What tire size fits a 2006 Dodge Trucks Ram 2500 ST?
The 2006 Dodge Trucks Ram 2500 ST uses a 245/70R17 radial tire. That size applies across the covered ST configurations, including 4x2 and 4x4, Quad Cab and Reg. Cab models, so the basic fitment question is unusually straightforward for this truck.
The practical step is confirming that the truck still has 17-inch wheels in an appropriate width range for the tire being considered. A Ram 2500 that has been modified with different wheels, lift components, or other suspension changes may still require a closer check of wheel dimensions and clearance before replacement.
What size rim does a 2006 Dodge Trucks Ram 2500 ST use?
The primary tire fitment for the 2006 Dodge Trucks Ram 2500 ST is built around a 17-inch rim. In the available 245/70R17 product offering, the supported rim-width range is 6.5 to 8.0 inches, which helps define the wheel fitment window for that tire.
Rim diameter is the first requirement, but width matters too because it affects how the tire seats and presents on the wheel. Anyone replacing tires on a used truck should confirm the actual wheel width stamped on the rim or verify it with a qualified tire professional before mounting a new set.
Do all 2006 Dodge Trucks Ram 2500 ST sub-models use the same tire size?
Yes. The covered 2006 Dodge Trucks Ram 2500 ST sub-models all use the same 245/70R17 radial tire size. That includes the 4x2 Quad Cab, 4x2 Reg. Cab, 4x4 Quad Cab, and 4x4 Reg. Cab versions in this fitment group.
That shared size makes replacement easier, but it does not eliminate the need to inspect the truck itself. A previous owner may have changed wheels or suspension height, and those changes can affect how a new tire sits in the wheel opening or how much clearance remains at full steering lock.
Choosing the Right Tire
What should I consider when choosing a 245/70R17 tire for a 2006 Dodge Trucks Ram 2500 ST?
Start with the correct 245/70R17 size, radial construction, and 17-inch wheel fitment. From there, compare the tire’s intended use, sidewall style, supported rim-width range, load specification, and overall character to match how the truck is actually driven, worked, or maintained.
A heavy-duty pickup often asks more of a tire than a light-duty commuter vehicle, so the choice should reflect real-world use rather than appearance alone. The available BFGoodrich option carries a 3,000-pound maximum load rating at 80 psi and suits buyers who want an all-terrain style in the correct fitment.
What sidewall styles are available for 2006 Dodge Trucks Ram 2500 ST tires?
The available 245/70R17 option for the 2006 Dodge Trucks Ram 2500 ST uses RWL sidewalls, meaning raised white letters. That styling gives the truck a more traditional light-truck appearance than a plain black sidewall and is often part of the visual appeal for owners who want a more rugged presentation.
Sidewall style does not change the tire size, but it does affect how the truck looks once the tires are mounted. Buyers who care about presentation should consider whether raised white letters suit the truck’s overall look, especially if the Ram is kept clean and close to an early-2000s period-style appearance.
What brands offer tires for the 2006 Dodge Trucks Ram 2500 ST?
The current 245/70R17 offering for the 2006 Dodge Trucks Ram 2500 ST is from BFGoodrich. It appears in the All Terrain T/A KO2 series, which places the available choice squarely in an all-terrain radial category rather than a highway-only or vintage-style collector tire category.
Brand selection is only one part of the decision. It still helps to compare the tire’s size, load specification, rim-width range, and tread personality to the way the truck is used, whether that means occasional hauling, regular road driving, or a more utility-focused setup with an all-terrain look.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Dodge Trucks Ram 2500 ST?
A period-style approach for a 2006 Dodge Trucks Ram 2500 ST starts with keeping the correct 245/70R17 radial size on a 17-inch wheel. That preserves the truck’s basic stance and fitment while allowing the owner to choose a tire that still feels appropriate to a heavy-duty Ram from the mid-2000s.
An all-terrain radial with raised white letters can suit that goal if the truck is meant to retain a traditional light-truck look rather than a fully modernized appearance. Exact originality questions go beyond size alone, so buyers focused on highly detailed presentation should compare their truck against period photos, literature, or marque-specific references.
How does tire construction affect the appearance of a restored 2006 Dodge Trucks Ram 2500 ST?
On a 2006 Dodge Trucks Ram 2500 ST, the primary fitment is already a radial, so the appearance question centers less on bias-ply versus radial and more on tread style and sidewall treatment. In this size, raised white letters create a more assertive truck look than a plain sidewall would.
That means a restoration-minded owner should think about how the tire complements the truck’s wheels, ride height, and overall presentation. Even when the fitment is modern enough to be straightforward, the wrong sidewall style or an overly aggressive tread can shift the Ram away from the clean, era-appropriate look some owners want.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Dodge Trucks Ram 2500 ST?
Yes. Even though the 2006 Dodge Trucks Ram 2500 ST uses a straightforward 245/70R17 fitment, wheel changes, altered wheel offset, lift kits, leveling kits, or suspension wear can all affect how that size sits on the truck. Clearance at the fender, steering components, and suspension points can change.
A truck that still wears its original-style wheel and suspension setup is much simpler to evaluate than one that has been modified. Before installing new tires, confirm actual wheel diameter and width, then inspect clearance through the full steering range so the chosen tire matches the Ram’s current physical setup.
What should I inspect before driving a 2006 Dodge Trucks Ram 2500 ST on new tires?
Inspect the wheel diameter and width first, then check that the tires are mounted in the correct 245/70R17 size and inflated appropriately for the intended load. It also helps to look over the suspension, steering components, and brake hardware so the new tires are working with a sound overall setup.
A short test drive should include listening for rubbing, feeling for pull or vibration, and confirming that the truck tracks properly at normal road speeds. On a heavy-duty pickup, it is also smart to recheck air pressure and lug torque after initial use, especially if the wheels have recently been removed.
How should 245/70R17 tires on a 2006 Dodge Trucks Ram 2500 ST be maintained?
Routine maintenance starts with regular pressure checks, visual inspection, and watching for uneven wear across the tread. On a 2006 Dodge Trucks Ram 2500 ST, that matters even more if the truck tows, hauls, or spends part of its time parked, since usage extremes can affect how the tires age and wear.
Keep an eye out for cracking, cuts, bulges, punctures, and persistent air loss, and inspect the tires before longer drives rather than only after a problem appears. A Ram that sees occasional use should also have its tires checked for age-related condition, because low annual mileage does not prevent rubber from deteriorating over time.
