The 2006 Dodge Trucks Ram 1500 SLT comes from the era when full-size pickups were expected to balance everyday drivability with real work and utility, and the Ram's bold styling made it one of the most recognizable trucks on the road. Tire choice on this exact model centers on three radial sizes: 245/70R17, 265/70R17, and 275/60R20, depending on cab and wheel setup. That makes this a fitment-first page, especially where 17-inch and 20-inch wheel packages overlap. For many owners, the real decision is confirming the truck's exact sub-model and wheel diameter, then comparing available load, sidewall, and use-oriented tire options.
Which Tire Size Is Right for The 2006 Dodge Trucks Ram 1500 SLT
Three primary tire sizes apply to the 2006 Dodge Trucks Ram 1500 SLT, and they do not all use the same wheel diameter. Fitment varies by sub-model and wheel package, with 17-inch options in 245/70R17 and 265/70R17, plus a 20-inch option in 275/60R20. The first step is confirming the exact cab and drivetrain combination, then checking whether the truck is actually wearing 17-inch or 20-inch wheels before choosing a tire.
Fit(s): 4x2 Mega Cab, 4x2 Quad Cab, 4x2 Reg. Cab, 4x4 Mega Cab, 4x4 Quad Cab, and 4x4 Reg. Cab
Construction: Radial|Rim: 17 in
265/70R17 is a metric radial size in which 265 identifies the nominal section width in millimeters, 70 is the aspect ratio, R designates radial construction, and 17 is the rim diameter in inches. On the 2006 Dodge Trucks Ram 1500 SLT, this is one of the key 17-inch fitments and appears across several cab and drivetrain combinations. Available choices in this size center on BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls and different load-capacity versions. This size is worth evaluating when the truck uses 17-inch wheels and needs a tire suited to pickup use rather than a lower-profile 20-inch presentation.
245/70R17 is a metric radial size that uses a 245-millimeter nominal section width, a 70-series profile, and a 17-inch wheel diameter. For the 2006 Dodge Trucks Ram 1500 SLT, it is a 17-inch fitment used on certain Quad Cab and Regular Cab configurations rather than across every SLT variant. Available product choice in this size includes a BFGoodrich All-Terrain T/A KO2 with raised white letter sidewalls and a load-focused LT construction. This size should be matched to the truck's actual wheel and sub-model setup before selection, especially where other 17-inch and 20-inch fitments are also possible.
275/60R20 is a metric radial size with a 275-millimeter nominal section width, a 60-series aspect ratio, and a 20-inch rim diameter. On the 2006 Dodge Trucks Ram 1500 SLT, this size belongs to certain Quad Cab and Regular Cab applications and stands apart from the 17-inch fitments because wheel diameter changes with it. Its lower-profile format gives it a different sizing convention from the taller 17-inch alternatives used elsewhere in the SLT range. This size should only be considered after confirming that the truck is equipped with 20-inch wheels and has the appropriate wheel-and-clearance setup for that package.
Sub-model identification matters on the 2006 Dodge Trucks Ram 1500 SLT because fitment is not the same across every cab and drivetrain combination. Mega Cab models stay with one 17-inch size, while Quad Cab and Reg. Cab versions can use more than one tire size and more than one wheel diameter.

2006 Dodge Trucks Ram 1500 SLT 4x2 Mega Cab
The 2006 Dodge Trucks Ram 1500 SLT 4x2 Mega Cab uses the 265/70R17 radial size rather than sharing the broader mix of sizes seen on some other SLT configurations. Tire selection here is more about choosing the right product within that size and confirming load and wheel compatibility than sorting through multiple primary fitments.
The 2006 Dodge Trucks Ram 1500 SLT 4x2 Quad Cab can use 245/70R17, 265/70R17, or 275/60R20, so wheel diameter must be confirmed before any tire choice is made. Once that is settled, the decision becomes matching the truck's actual wheel package to the correct size and comparing the available tire specifications within that fitment.
The 2006 Dodge Trucks Ram 1500 SLT 4x2 Reg. Cab also spans 245/70R17, 265/70R17, and 275/60R20, making it one of the configurations where a quick visual check is not enough. Tire selection should begin with the actual wheel diameter on the truck, then move to the correct radial size for that setup.
The 2006 Dodge Trucks Ram 1500 SLT 4x4 Mega Cab uses 265/70R17, keeping fitment straightforward compared with the wider range seen on other SLT body styles. That allows the buyer to focus on product details such as load version, rim-width compatibility, and intended truck use within the same primary size.
The 2006 Dodge Trucks Ram 1500 SLT 4x4 Quad Cab can be matched with 245/70R17, 265/70R17, or 275/60R20 depending on the wheel package. The practical takeaway is simple: verify the exact wheel diameter first, then choose within the correct radial size instead of assuming every SLT Quad Cab uses the same tire.
The 2006 Dodge Trucks Ram 1500 SLT 4x4 Reg. Cab shares the same three-size fitment pattern of 245/70R17, 265/70R17, and 275/60R20. That makes wheel confirmation especially important before comparing tires, since the right choice depends on the truck's actual 17-inch or 20-inch setup.

Owners of a 2006 Dodge Trucks Ram 1500 SLT usually need to sort out exact tire size, wheel diameter, and sub-model fitment first. The questions below focus on size meaning, product selection, wheel compatibility, and practical inspection points before road use.
Tire Size & Fitment
What tire size fits a 2006 Dodge Trucks Ram 1500 SLT?
The 2006 Dodge Trucks Ram 1500 SLT uses one of three radial tire sizes: 245/70R17, 265/70R17, or 275/60R20. The exact fitment depends on the truck's sub-model and wheel package, with Mega Cab versions using 265/70R17 while certain Quad Cab and Reg. Cab versions can use more than one size.
The practical step is to confirm the truck's exact cab and drivetrain configuration, then verify whether it has 17-inch or 20-inch wheels. That matters more than assuming all SLT trucks share one size, especially since both 17-inch and 20-inch fitments appear in the same model line.
What size rim does a 2006 Dodge Trucks Ram 1500 SLT use?
A 2006 Dodge Trucks Ram 1500 SLT uses either a 17-inch or 20-inch rim, depending on the tire size and sub-model setup. The 245/70R17 and 265/70R17 sizes use 17-inch rims, while the 275/60R20 size uses a 20-inch rim.
Rim diameter should be checked before anything else because a tire for a 17-inch wheel cannot be mounted on a 20-inch wheel, and the reverse is equally true. Looking at the sidewall size already on the truck and measuring the wheel package against the actual vehicle helps prevent ordering the right tire in the wrong diameter.
Do all 2006 Dodge Trucks Ram 1500 SLT sub-models use the same tire size?
No. The 2006 Dodge Trucks Ram 1500 SLT does not use one universal tire size across every sub-model. Mega Cab versions use 265/70R17, while Quad Cab and Reg. Cab versions can be fitted with 245/70R17, 265/70R17, or 275/60R20 depending on configuration and wheel package.
That variation means the sub-model name alone is helpful, but the actual wheel on the truck is just as important. A buyer should confirm both the exact body style and the current wheel diameter, especially if the truck has changed hands or may have received replacement wheels at some point.
Choosing the Right Tire
What should I consider when choosing a 265/70R17 tire for a 2006 Dodge Trucks Ram 1500 SLT?
Start with the basics: confirm that 265/70R17 is the correct primary size for the truck, then compare the available radial versions within that size. For this Ram 1500 SLT, 265/70R17 choices include BFGoodrich All-Terrain T/A KO2 tires with raised white letter sidewalls and different load-capacity specifications.
The next step is matching the tire to how the truck is actually used. Rim-width compatibility, load capacity, and whether the truck sees mostly street driving or mixed on- and off-road use are more important than choosing by appearance alone, even when the sidewall treatment is part of the appeal.
What sidewall styles are available for 2006 Dodge Trucks Ram 1500 SLT tires?
The available products shown for the 2006 Dodge Trucks Ram 1500 SLT use RWL sidewalls, meaning raised white letter styling. That sidewall treatment appears on the BFGoodrich All-Terrain T/A KO2 products available in the supported 17-inch sizes here.
Sidewall style affects the truck's presentation, but it should still be considered after the correct size and wheel diameter have been confirmed. A raised white letter tire can suit the Ram's early-2000s truck character well, though load specification, rim-width range, and intended use remain the more important fitment decisions.
What brands offer tires for the 2006 Dodge Trucks Ram 1500 SLT?
The available products for the supported sizes shown here come from BFGoodrich. Those offerings center on the All-Terrain T/A KO2 radial line in the 245/70R17 and 265/70R17 sizes used on 17-inch wheel applications for the 2006 Dodge Trucks Ram 1500 SLT.
Brand is only one part of the decision. After confirming the truck's correct size, compare the actual specifications within that brand's offerings, including load version, wheel-width compatibility, and sidewall treatment, so the tire matches both the truck's fitment and the owner's intended use.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Dodge Trucks Ram 1500 SLT?
A period-style choice for a 2006 Dodge Trucks Ram 1500 SLT starts with the truck's correct original-size format for its actual wheel package: 245/70R17, 265/70R17, or 275/60R20. Staying with the proper radial size and wheel diameter preserves the truck's intended stance more effectively than choosing a size on appearance alone.
Appearance still matters, especially on a clean early-2000s pickup, but fitment comes first. Raised white letter sidewalls can complement the era's truck look, while exact originality questions are best checked against window-sticker, build-sheet, or marque-specific references if a highly detailed restoration is the goal.
Does correct tire fitment matter for a 2006 Dodge Trucks Ram 1500 SLT restoration?
Yes, correct tire fitment matters because the 2006 Dodge Trucks Ram 1500 SLT was offered with more than one size and more than one wheel diameter. Using the wrong combination can change the truck's appearance, alter how it sits on the wheel openings, and complicate wheel or clearance compatibility.
A restoration-minded owner should confirm the truck's actual sub-model and wheel package before choosing tires. Matching the right size first, then selecting the preferred sidewall and product details within that fitment, keeps the result visually coherent without assuming every SLT left the factory with the same setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Dodge Trucks Ram 1500 SLT?
Yes. Modifications such as aftermarket wheels, different wheel widths, suspension changes, lift or lowering work, and body alterations can all affect tire fitment on a 2006 Dodge Trucks Ram 1500 SLT. That is especially important here because the truck already spans both 17-inch and 20-inch factory-type fitment paths.
Any truck that has been changed from stock should be checked for actual wheel diameter, wheel width, and clearance at full steering lock and suspension travel. A tire that matches the sidewall size you expect still needs to be evaluated against the Ram's current setup rather than its original configuration alone.
What should I inspect before driving a 2006 Dodge Trucks Ram 1500 SLT on new tires?
Before road use, inspect tire pressure, bead seating, lug torque, visible sidewall condition, and tread area for shipping or mounting damage. On a 2006 Dodge Trucks Ram 1500 SLT, it also makes sense to confirm that the new tires match the truck's actual wheel diameter and that all four installed tires are the intended size.
A short, careful test drive can reveal rubbing, pull, vibration, or clearance issues that are easier to address early. It is also wise to look over suspension and steering components on an older pickup, since worn parts can affect how any correctly sized tire behaves once the truck is back on the road.
What should I check before a longer drive in a 2006 Dodge Trucks Ram 1500 SLT?
Before a longer drive, check inflation pressure, tread condition, sidewall condition, and any signs of slow air loss on the 2006 Dodge Trucks Ram 1500 SLT. It is also smart to verify that the truck is running the correct size for its wheel package, especially if it was recently purchased or has had wheels changed over time.
Longer trips put more emphasis on consistent pressure, stable wear, and proper load carrying. Looking for cracking, bulges, cuts, or uneven wear before departure helps catch problems early, and a quick review of the spare and wheel hardware adds another layer of preparedness for an older full-size truck.
