The 2006 Dodge Trucks Ram 1500 ST belongs to an era when full-size pickups were expected to handle daily driving, jobsite duty, and weekend use without giving up stance or presence. In ST trim, tire selection is less about vintage restoration and more about matching the truck’s exact cab and drivetrain setup. This Ram 1500 ST uses 17-inch radial fitments in either 245/70R17 or 265/70R17, with size variation tied to specific sub-model configurations. Available choices stay within an all-terrain radial theme, including raised white letter styling. The key step is confirming the exact 4x2 or 4x4 cab configuration before comparing load capacity, rim-width compatibility, and overall tire character.
Which Tire Size Is Right for The 2006 Dodge Trucks Ram 1500 ST
Two primary tire sizes apply to the 2006 Dodge Trucks Ram 1500 ST, and both use radial construction on 17-inch rims. The right choice depends first on the exact sub-model, since some 4x2 trucks use 245/70R17 while certain 4x4 configurations can use either 245/70R17 or 265/70R17. Once the truck’s configuration is confirmed, the next step is comparing tire width, load capacity, and rim-width compatibility within the correct size.
245/70R17 is a metric radial size in which 245 identifies nominal section width in millimeters, 70 is the aspect ratio, R denotes radial construction, and 17 is the wheel diameter in inches. On the 2006 Dodge Trucks Ram 1500 ST, this size suits 17-inch wheel setups and is used on several covered sub-models. Available product choice centers on BFGoodrich’s All-Terrain T/A KO2 with raised white letter sidewalls. This size is worth considering when the truck’s original configuration calls for it and the goal is to stay with a moderately sized all-terrain radial footprint.
265/70R17 is also a metric radial size, with a 265-millimeter nominal section width, a 70-series profile, radial construction, and a 17-inch rim requirement. For the 2006 Dodge Trucks Ram 1500 ST, this size applies to certain 4x4 configurations rather than every ST model. BFGoodrich All-Terrain T/A KO2 options are available here as well, both with raised white letter styling and differing load-capacity specifications. This size becomes the one to evaluate when the truck’s wheel setup and sub-model support a wider all-terrain tire on the same rim diameter.
Sub-model fitment matters on the 2006 Dodge Trucks Ram 1500 ST because tire size changes with cab and drivetrain configuration. The 4x2 trucks stay straightforward, while the 4x4 Quad Cab and 4x4 Reg. Cab require a closer look because more than one primary size may apply.

2006 Dodge Trucks Ram 1500 ST 4x2 Quad Cab
The 2006 Dodge Trucks Ram 1500 ST 4x2 Quad Cab uses the 245/70R17 radial size. Tire selection here is mainly about choosing the right all-terrain product characteristics within that size, while also confirming rim width and load needs for the truck’s actual use.
The 2006 Dodge Trucks Ram 1500 ST 4x2 Reg. Cab also uses 245/70R17 radial tires on a 17-inch rim. That keeps fitment simple, so the real decision shifts to tire specification details such as sidewall presentation, load rating, and compatibility with the wheels currently on the truck.
The 2006 Dodge Trucks Ram 1500 ST 4x4 Quad Cab can use either 245/70R17 or 265/70R17 radial tires. That makes wheel and current-tire verification especially important before replacement, since the right choice depends on the truck’s actual setup rather than the model name alone.
The 2006 Dodge Trucks Ram 1500 ST 4x4 Reg. Cab may be fitted with either 245/70R17 or 265/70R17 radials. Before choosing between them, it is smart to confirm the wheel width already on the truck and make sure the replacement tire matches the intended stance, load requirement, and clearance envelope.
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.
Best 2006 Dodge Trucks Ram 1500 ST Tires for Sale
Available 17-inch Ram 1500 ST tires focus on BFGoodrich All-Terrain T/A KO2 radials in 245/70R17 and 265/70R17. The main comparison points are load-capacity specification, rim-width range, and the raised white letter sidewall treatment used across these all-terrain options.
Owners of a 2006 Dodge Trucks Ram 1500 ST usually need to confirm the right tire size by sub-model first, then compare radial specifications, wheel compatibility, load capacity, and practical road-use considerations before choosing a replacement tire.
Tire Size & Fitment
What tire size fits a 2006 Dodge Trucks Ram 1500 ST?
The 2006 Dodge Trucks Ram 1500 ST uses either 245/70R17 or 265/70R17 tires, both in radial construction on 17-inch rims. The correct size depends on the truck’s exact sub-model, because the 4x2 Quad Cab and 4x2 Reg. Cab use 245/70R17, while the 4x4 Quad Cab and 4x4 Reg. Cab may use either size.
That means the safest starting point is the truck’s actual cab and drivetrain configuration, not just the Ram 1500 ST badge. It is also smart to verify the wheels currently installed, since a previous owner may have changed sizes. Matching the replacement tire to the existing wheel width and the truck’s intended use helps avoid unnecessary fitment problems.
What size rim does a 2006 Dodge Trucks Ram 1500 ST use?
The tire fitments covered for the 2006 Dodge Trucks Ram 1500 ST use a 17-inch rim diameter. Both 245/70R17 and 265/70R17 are built around that same 17-inch wheel size, so the rim diameter itself stays consistent even though the tire width can change between sub-models.
Rim diameter is only part of the fitment picture, so it should not be the only measurement checked before replacement. Wheel width matters too, especially when moving between the two supported tire sizes. Confirming both the wheel diameter and wheel width helps narrow the correct choice and keeps the comparison focused on tires that suit the truck’s setup.
Do all 2006 Dodge Trucks Ram 1500 ST sub-models use the same tire size?
No, the 2006 Dodge Trucks Ram 1500 ST does not use one tire size across every covered sub-model. The 4x2 Quad Cab and 4x2 Reg. Cab use 245/70R17, while the 4x4 Quad Cab and 4x4 Reg. Cab can use either 245/70R17 or 265/70R17.
That variation is why sub-model confirmation matters before comparing tires. A buyer looking at a 4x4 truck should also inspect the wheels and current tires already on the vehicle, because either supported size may be present. Once the exact setup is confirmed, choices become much easier to compare by load specification, rim-width range, and overall tire character.
Choosing the Right Tire
What should I consider when choosing a 245/70R17 tire for a 2006 Dodge Trucks Ram 1500 ST?
Start with fitment accuracy. On the 2006 Dodge Trucks Ram 1500 ST, 245/70R17 is the correct radial size for the 4x2 Quad Cab and 4x2 Reg. Cab, and it also appears on certain 4x4 configurations. In the available selection, this size is offered as a BFGoodrich All-Terrain T/A KO2 with raised white letter styling.
After confirming the truck actually uses 245/70R17, compare wheel-width compatibility and the tire’s load specification against how the truck is driven or worked. A daily-driven pickup, a lightly used second truck, and a truck that sees more cargo or rougher surfaces can place different demands on the same nominal tire size.
What brands offer tires for the 2006 Dodge Trucks Ram 1500 ST?
The available products for the covered 2006 Dodge Trucks Ram 1500 ST fitments are from BFGoodrich. The tire series offered is the All-Terrain T/A KO2, available in the supported 17-inch sizes used on this truck and shown with raised white letter sidewall styling.
Since brand choice is narrow here, the better comparison is between the supported sizes and their related specifications rather than between multiple manufacturers. Once the correct sub-model and tire size are confirmed, focus on factors such as wheel-width range, load capacity, and whether the truck’s intended use calls for the narrower or wider supported fitment.
What sidewall styles are available for 2006 Dodge Trucks Ram 1500 ST tires?
The available tire options for the covered 2006 Dodge Trucks Ram 1500 ST fitments use RWL sidewalls, meaning raised white letter styling. That gives the truck a more traditional light-truck all-terrain appearance than a plain blackwall, while staying within the radial tire sizes used on this 17-inch Ram setup.
Sidewall style does not change the basic fitment, but it can affect the truck’s overall presentation quite a bit. Buyers who want a more assertive period-inspired truck look may prefer raised white letters, while others may care more about size, load specification, and wheel compatibility first. Appearance should follow correct fitment, not replace it.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Dodge Trucks Ram 1500 ST?
A period-style choice for a 2006 Dodge Trucks Ram 1500 ST starts with the correct original-size family for the truck’s exact configuration: 245/70R17 or, on some 4x4 models, 265/70R17. Since this Ram uses modern radial sizing rather than vintage bias-ply formats, the right visual approach comes from keeping the proper stance and proportions for the truck.
The available BFGoodrich All-Terrain T/A KO2 options suit a truck-oriented appearance, especially with raised white letter sidewalls. For an owner focused on preserving the truck’s early-2000s look, matching the correct size to the current wheel setup matters more than chasing an aggressive upsized replacement that changes the Ram’s overall visual balance.
How does tire construction affect the appearance of a restored 2006 Dodge Trucks Ram 1500 ST?
On a 2006 Dodge Trucks Ram 1500 ST, appearance is shaped more by the correct modern radial size and sidewall treatment than by a bias-ply-versus-radial choice, because the primary fitments here are radial. The supported options also use a truck-oriented raised white letter look, which gives the Ram a more purposeful all-terrain presentation.
Keeping the proper size for the truck’s exact sub-model helps preserve ride height, wheel-well fill, and overall stance. A restoration-minded owner should also pay attention to wheel choice, since the wrong width or a heavily altered aftermarket setup can change how the tire looks on the truck even when the tire itself is in a supported size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Dodge Trucks Ram 1500 ST?
Yes, modifications can affect tire fitment on a 2006 Dodge Trucks Ram 1500 ST even when the tire size is one of the supported 17-inch options. Changes such as aftermarket wheels, different wheel widths, altered offset, suspension lifts, lowering, or body trimming can all influence how a 245/70R17 or 265/70R17 tire sits and clears.
A truck that has been changed from stock should be checked at the wheel openings and through steering travel before a replacement tire is chosen. It also helps to confirm the wheel width already on the truck, since that can determine whether a supported size is still appropriate for the setup now on the vehicle.
What should I inspect before driving a 2006 Dodge Trucks Ram 1500 ST on new tires?
Before putting a 2006 Dodge Trucks Ram 1500 ST back into regular use on new tires, inspect the wheels, valve stems, and basic alignment condition along with the tires themselves. It is also smart to make sure the chosen tire matches the truck’s actual sub-model fitment, and that inflation is set appropriately for the tire specification and intended use.
A short check drive should confirm there is no rubbing at full steering lock, under suspension movement, or with the truck carrying its normal load. Uneven old-tire wear can also point to suspension or alignment issues that should be corrected, since replacing the tires alone will not solve a wear pattern caused by the chassis.
How often should tires on a 2006 Dodge Trucks Ram 1500 ST be inspected?
Tires on a 2006 Dodge Trucks Ram 1500 ST should be inspected regularly, not just when tread looks low. A monthly visual check is a sensible routine for a truck in active use, with added attention before towing, hauling, or taking a longer highway trip. Look for air loss, cuts, bulges, irregular wear, and sidewall damage.
A truck that sits for stretches still benefits from routine inspection because age, underinflation, and exposure can matter even when mileage stays low. Pressure should be checked with the tires cold, and any change in ride feel, steering response, or visible shoulder wear deserves a closer look before the Ram is put back into daily service.
