OEM wheel and tire fitment specs for the 2007 Dodge Ram 2500, including bolt pattern (PCD), center bore diameter, thread size, rim diameter, rim width, wheel offset, and backspacing.
2007 Dodge Ram 2500 Fitment Specs
Baseline mounting dimensions used for interchange decisions.
Multiple OEM configurations exist for this vehicle. Fitment can vary by trim, brakes, and factory wheel package – confirm your exact setup before buying.
Wheels That Interchange With a 2007 Dodge Ram 2500
Results are evaluated from bolt pattern, center bore direction, OEM width/offset envelope, and lug hardware – not bolt pattern alone.
A normal wheel spacer does not change bolt pattern. Hub rings cannot enlarge a wheel bore that is smaller than the hub. Brake clearance and tire package fitment still require vehicle-specific checks when not confirmed in the dataset.

OEM tire size example
245/70R17 on a 17 in wheel - some trims used 17 in factory wheels
Notes:
Wheel and tire sizes varied by trim and package in 2007. You may see factory 17 in or 18 in packages. Do not assume your truck matches the sample above.
If your current wheels are OEM, the size is often cast or stamped on the inboard barrel or on the back of a spoke. Tires list their size on the sidewall.
Never mix dually wheels with single rear wheel setups. The Ram 2500 is SRW from the factory.
How To Use The Wheel Interchange Calculator
The calculator lets you compare a potential wheel and tire setup against your 2007 Ram 2500 to check clearances, poke, and diameter changes.
Step 1 - Set Installed on: Choose 2007 Dodge Ram 2500. Enter your actual stock wheel and tire sizes from your truck. If your label shows 17 in factory wheels, input that. If you have 18x7.5 ET45, input those values.
Step 2 - Set Wheels from: Enter the donor vehicle specs or manually input the custom wheel diameter, width, and offset you want to try.
Step 3 - Custom tire size: If you change rim diameter or want different tires, enter section width and aspect ratio. The tool updates overall diameter automatically.
Step 4 - Review results: Check inner clearance to suspension, outer poke vs fenders, ride height change, and speedometer error.
Step 5 - Decide: Aim for minimal inner clearance loss, controlled outer poke, and overall tire diameter within about plus or minus 3 percent of your current diameter for best ABS, gearing, and speedometer behavior.
Tip: If you widen the wheel, you often reduce offset to keep inner clearance similar. Example - going from 7.5 in to 9.0 in width adds 1.5 in total. Half of that is 0.75 in, which is about 19 mm. Reducing offset by about 19 mm keeps the inner edge near stock. Always confirm with the calculator and a test fit.
Fitment Checklist Before You Buy
Bolt pattern: Must be 8x165.1 mm. Anything else will not mount safely.
Center bore: Truck hub is 121.3 mm. A wheel with a larger bore can work with 121.3 hub-centric rings. A smaller bore will not fit.
Wheel load rating: Choose wheels and tires with load ratings that meet or exceed your axle GAWR and towing needs.
Offset and backspacing: Compare with the calculator. Ensure inner clearance at the knuckle, control arms, leafs, and sway bar. Avoid excessive outer poke that may hit fenders at full compression or steering lock.
Brake and hub clearance: Physically test-fit to confirm caliper and hub cap clearance, especially with smaller diameters or thick spoke designs.
Lug hardware: Thread is M14 x 1.5. Match the lug seat type to the wheel design, such as 60 degree conical vs mag seat. Do not mix seat types.
TPMS: If equipped, plan to transfer sensors or install compatible ones and perform a relearn per the service manual.
Spacers or adapters: Only use quality hub-centric parts when needed, and verify thread engagement and fender coverage laws. Re-check torque frequently.
Plus Sizing And Common Upgrades
Owners often move between 17 in and 18 in factory-equivalent packages, or upsize while keeping overall diameter near stock for drivability. Follow these principles:
Keep overall tire diameter close to stock - typically within plus or minus 3 percent - to preserve speedometer accuracy, ABS calibration, and towing performance.
When increasing wheel width, reduce offset as needed so the inner barrel does not contact suspension. Use the calculator to quantify inner clearance and outer poke changes.
For towing and heavy hauling, avoid very short sidewalls. A tire with adequate load rating and sidewall height helps ride quality and rim protection.
Match tire to rim width. Use the tire manufacturer’s recommended rim width range for the exact tire size you choose.
If you plan aggressive off-road tires, confirm fender and bumper clearance at full lock and full compression. Some setups may require trimming or suspension changes. The calculator helps you estimate, but a test fit is best.
Because factory sizes varied by trim in 2007, verify your current baseline size on the truck, then use the calculator to model any plus-size change before you buy.
Installation Tips
Safety first: Park on level ground, chock wheels, use a proper jack and jack stands at approved lift points from the service manual.
Prep the hub: Clean the hub face and center register with a wire brush. Lightly remove rust. A clean, flat interface reduces runout and vibration.
Hub-centric rings: If the wheel bore is larger than 121.3 mm, install correct 121.3 rings so the wheel centers on the hub.
Lug nuts: Hand start every lug to avoid cross-threading. Match seat type to the wheel. Do not lubricate studs or nuts unless the OEM procedure specifies it.
Torque: Tighten in a star pattern in 2 to 3 stages to the OEM wheel torque spec from your owner’s manual or dealer. Re-torque after 50 to 100 miles.
Stud engagement: Ensure at least one full stud diameter of thread engagement on each M14 x 1.5 stud. If using spacers, verify longer studs or proper nuts as required.
Final checks: Spin each wheel by hand to confirm no interference, then road test gently and re-check torque and clearances.

FAQs
Can I use 17 in wheels on my 2007 Ram 2500?
Some 2007 Ram 2500 trucks were factory-equipped with 17 in wheels and 245/70R17 tires. If your brakes and calipers clear the chosen 17 in design and the wheel meets the 8x165.1 bolt pattern, 121.3 mm bore, and load rating, it can work. Confirm with the calculator and a physical test fit.
What is the stock offset for this truck?
One confirmed OEM wheel is 18x7.5 with ET 45 mm. Other OEM sizes in 2007 may differ by trim. Check your wheel stamping, door-jamb label, or OEM parts resources to verify your exact offset.
Which other vehicles’ wheels will interchange?
Many heavy-duty wheels use the 8x165.1 pattern, but center bore, offset, hub design, and load rating vary. Do not assume fitment. Enter the donor wheel specs into the calculator and verify bore, offset, and load rating before purchase. Test fit whenever possible.
Do I need hub-centric rings?
If the aftermarket wheel’s center bore is larger than 121.3 mm, use 121.3 rings so the wheel centers on the hub. If the bore is exactly 121.3, no ring is needed. A smaller bore will not fit.
Are spacers safe to use?
Quality hub-centric spacers sized for 8x165.1 can be safe when installed correctly with proper thread engagement and torque. They change effective offset and scrub radius, and may affect fender coverage. Use only when necessary and recheck torque often. Follow local regulations.
What torque should I use on the lug nuts?
Use the OEM torque specification from your owner’s manual or dealer service information for the 2007 Ram 2500. Do not guess. Re-torque after 50 to 100 miles.
How much diameter change is acceptable without recalibrating?
As a general guideline, stay within about plus or minus 3 percent of your current tire diameter to keep speedometer and ABS behavior near stock. Verify with the calculator.
