The 2006 Dodge Trucks Ram 2500 TRX4 sits in the heavy-duty pickup era when off-road appearance and real work capability often came together in one package. On a truck like this, tire choice affects not just stance, but also load support, road manners, and how the TRX4 presents itself on stock-style 17-inch wheels. The primary fitment is a 265/70R17 radial, used across the covered TRX4 configurations here. Available choices stay focused within that size, including BFGoodrich All-Terrain T/A KO2 options with raised white letter sidewalls. The key decision is less about changing sizes and more about matching the right load specification and intended use to the truck you actually have.
Which Tire Size Is Right for The 2006 Dodge Trucks Ram 2500 TRX4
The 2006 Dodge Trucks Ram 2500 TRX4 uses one primary tire size: 265/70R17, a radial tire mounted on a 17-inch rim. That fitment carries across the covered 4x4 Quad Cab and 4x4 Reg. Cab versions, so the main decision is choosing the right tire within the size, especially load specification, sidewall presentation, and how the truck will be driven or worked.
265/70R17 is a metric radial size where 265 identifies the nominal section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. For the 2006 Dodge Trucks Ram 2500 TRX4, this is the core fitment and it suits the truck's modern heavy-duty pickup character better than an older bias-ply sizing system would. Available options in this size include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls. The important comparison within this size is load specification, along with making sure the wheel remains within the tire's approved rim-width range.
Tire fitment is straightforward across the covered 2006 Dodge Trucks Ram 2500 TRX4 sub-models because they share the same primary size. Checking the exact cab configuration still matters, but the tire decision remains centered on choosing the right 265/70R17 radial for the truck's use and wheel setup.

2006 Dodge Trucks Ram 2500 TRX4 4x4 Quad Cab
The 2006 Dodge Trucks Ram 2500 TRX4 4x4 Quad Cab uses the same 265/70R17 radial fitment as the other covered TRX4 configuration. Tire selection is mainly about choosing the proper load-rated option, confirming 17-inch wheel compatibility, and deciding whether the raised white letter all-terrain look suits the truck's intended use.
The 2006 Dodge Trucks Ram 2500 TRX4 4x4 Reg. Cab also uses the 265/70R17 radial size. That keeps the fitment side simple, so the real comparison comes down to the tire's load capacity, approved rim-width range, and whether the truck still carries its original-style wheel and suspension setup.
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 2006 Dodge Trucks Ram 2500 TRX4?
The 2006 Dodge Trucks Ram 2500 TRX4 uses a 265/70R17 radial tire. That size applies to the covered 4x4 Quad Cab and 4x4 Reg. Cab versions, making fitment more straightforward than on trucks that vary by trim or wheel package.
The practical step is confirming that the truck still has 17-inch wheels and has not been changed to an aftermarket wheel-and-tire setup. Once the size is confirmed, attention shifts to the tire's approved rim-width range, load specification, and whether the intended use is mostly road driving, mixed use, or work that calls for greater load support.
What size rim does a 2006 Dodge Trucks Ram 2500 TRX4 use?
The primary tire fitment for the 2006 Dodge Trucks Ram 2500 TRX4 is built around a 17-inch rim diameter. The 265/70R17 size itself confirms that wheel diameter, since the final number in the size is the wheel size in inches.
Wheel diameter is only part of the fitment picture, so the wheel width should also be checked before selecting a tire. Available 265/70R17 options here are intended for wheels within a 7.0- to 9.0-inch rim-width range, and that matters just as much as diameter when the truck has replacement wheels or a changed stance.
Do all 2006 Dodge Trucks Ram 2500 TRX4 sub-models use the same tire size?
The covered 2006 Dodge Trucks Ram 2500 TRX4 sub-models use the same 265/70R17 radial tire size. That includes both the 4x4 Quad Cab and the 4x4 Reg. Cab configurations, so there is no split fitment between those versions here.
That shared size simplifies tire shopping, but it does not remove the need to verify the truck's actual wheel setup. A previous owner may have changed wheel width, offset, suspension height, or tire type, so matching the tire to the current truck is still important even when the original fitment stays consistent across sub-models.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2006 Dodge Trucks Ram 2500 TRX4?
Start with the correct size, 265/70R17, and then compare the tire's construction, load specification, and approved wheel width. On this truck, those details matter because a Ram 2500 can see anything from regular road use to hauling, towing, or rougher terrain.
The available choices here also differ in maximum load capacity and weight, so the better match depends on how the truck is actually used. A lightly used weekend truck may not need the same tire specification as one carrying heavier demands, and the wheel should still fall within the tire's 7.0- to 9.0-inch rim-width range.
What sidewall styles are available for 2006 Dodge Trucks Ram 2500 TRX4 tires?
The available 265/70R17 tires for the 2006 Dodge Trucks Ram 2500 TRX4 use an RWL sidewall style. That means raised white letter sidewalls, a look that suits many truck owners who want a more traditional all-terrain presentation rather than a plain blackwall appearance.
Sidewall style is mostly an appearance decision, but it still matters on a truck with visible wheel openings and an off-road-oriented character. The better choice depends on whether the goal is a stock-style truck look, a more aggressive period truck stance, or simply matching the sidewall presentation already used on the rest of the vehicle.
What brands offer tires for the 2006 Dodge Trucks Ram 2500 TRX4?
BFGoodrich offers the available 265/70R17 fitment choices here for the 2006 Dodge Trucks Ram 2500 TRX4. The product line represented is the All-Terrain T/A KO2, which keeps the selection focused rather than spreading across multiple brands and unrelated tire types.
A single-brand lineup does not remove the need to compare details within the size. The important differences still include load capacity, weight, and matching the tire to the truck's actual use, whether that is general road driving, heavier-duty service, or an all-terrain setup that benefits from the KO2's truck-oriented character.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Dodge Trucks Ram 2500 TRX4?
A period-style choice for a 2006 Dodge Trucks Ram 2500 TRX4 starts with retaining the original fitment size of 265/70R17 and staying with a truck-appropriate radial construction. That preserves the basic proportions and wheel relationship the TRX4 was designed around.
Appearance then comes down to the tire's character and sidewall treatment rather than changing to a different size. An all-terrain pattern with raised white letters gives the truck a strong mid-2000s heavy-duty pickup look, while wheel changes or oversized replacements can quickly alter the stance and visual balance that make the truck look right.
How does tire construction affect the appearance of a restored 2006 Dodge Trucks Ram 2500 TRX4?
On a 2006 Dodge Trucks Ram 2500 TRX4, radial construction is part of the truck's normal fitment and overall visual character. The appearance question is less about choosing between bias-ply and radial, and more about maintaining the right size, sidewall profile, and truck-appropriate tread style.
Keeping the 265/70R17 size helps the truck retain its intended proportions on 17-inch wheels. Sidewall styling also changes the final presentation, and the raised white letter look available in this fitment can reinforce a restoration-minded or era-appropriate truck appearance without claiming a specific factory-original tire branding or sidewall treatment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Dodge Trucks Ram 2500 TRX4?
Yes, modifications can affect tire fitment on a 2006 Dodge Trucks Ram 2500 TRX4 even when the original size is 265/70R17. Changes such as aftermarket wheels, different wheel offset, suspension lifts, lowering, or altered steering components can all influence clearance and how the tire sits in the wheel opening.
The safest approach is to verify the truck's actual wheel diameter and width, then check for steering, suspension, and fender clearance at full lock and through suspension travel. A truck that has been changed from its stock-style setup may still use the same nominal size, but the fitment conditions around that size can be very different.
What should I inspect before driving a 2006 Dodge Trucks Ram 2500 TRX4 on new tires?
Before driving a 2006 Dodge Trucks Ram 2500 TRX4 on new tires, inspect wheel condition, valve stems, lug hardware, and inflation pressure, then confirm that the tires seat correctly on the wheels. It also helps to check that the truck tracks straight and that there is no immediate interference at normal ride height.
A heavy-duty pickup deserves a second look after a short initial drive. Recheck pressure, inspect for rubbing near the inner fender and suspension, and make sure the tires clear at full steering lock. Any vibration, pull, or contact mark should be addressed early, especially on a truck expected to carry weight or cover highway miles.
How should 265/70R17 tires on a collector-era 2006 Dodge Trucks Ram 2500 TRX4 be maintained?
265/70R17 tires on a 2006 Dodge Trucks Ram 2500 TRX4 should be maintained with regular pressure checks, visual inspections, and routine attention to tread wear and sidewall condition. Even on a low-mile truck, age, storage conditions, and long periods of sitting can affect tire condition before tread is actually worn out.
A truck that sees occasional use benefits from being stored away from prolonged sun, moisture, and ozone-producing equipment, then inspected for cracking, bulges, cuts, or air loss before each outing. Keeping alignment and suspension in good order also matters, since uneven wear on a heavy-duty pickup can shorten tire life even when mileage stays modest.
