2008 Dodge Magnum Wheel Fitment Guide
Known OEM Fitment For 2008 Dodge Magnum
The values below reflect fitment data available for the 2008 Dodge Magnum. Some trims and option packages may use different wheel and tire sizes. Always verify against your driver-door jamb tire placard and owner manual. If your vehicle shows a different size, treat that as your baseline and use the on-page calculator to compare changes.
| Spec | Value | Notes |
| Bolt pattern | 5x115 | 5 studs on a 115 mm pitch circle |
| Center bore | 71.6 mm | Use hub-centric rings if aftermarket wheel bore is larger |
| Thread size | M14 x 1.5 | Confirm lug seat type for your specific wheel |
| OEM rim diameter | 18 in | Listed for at least one 2008 trim |
| OEM rim width | 7.5 in | Width associated with the 18 in rim listing |
| OEM wheel offset | ET 24 mm | Baseline for inner and outer clearance comparisons |
| OEM backspacing | 4.69 in | Measurement methods vary by source; verify by direct measurement if needed |
| OEM tire size | 215/65R17 | Indicates at least one 2008 trim shipped with 17 in wheels |
Note: The presence of both an 18x7.5 ET24 wheel listing and a 215/65R17 tire listing indicates multiple OEM packages were used in 2008. Use your exact placard size as the reference in the calculator and for speedometer and clearance calculations.
How To Use The Wheel Interchange Calculator
The calculator on wheelinterchange.com lets you compare a donor wheel or a custom setup to your 2008 Dodge Magnum and visualize clearance and diameter changes. Follow these steps:
- Select Wheels from (donor vehicle). Pick the vehicle the wheels came from, or leave it blank if you are testing a custom size.
- Select Installed on (your vehicle) and choose 2008 Dodge Magnum. This becomes your baseline.
- Enter Custom wheel size if you are considering aftermarket rims. Set rim diameter, rim width, and offset. The tool will update inner clearance and outer poke relative to the baseline.
- Enter Custom tire size by section width and aspect ratio. Changing rim diameter updates overall tire diameter in the comparison.
- Review results for inner clearance to the strut and knuckle, and outer position relative to the fender. The tool will also show overall diameter change for speedometer impact.
- Brake caliper shape and spoke design are not simulated. Always perform a physical test fit to confirm caliper and spoke clearance.
If your door placard shows a different OEM wheel or tire size than listed above, set that as the baseline in the calculator before comparing.
Fitment Checklist Before You Buy
- Bolt pattern: Must be 5x115. Do not rely on 5x114.3 as a direct fit.
- Center bore: Vehicle hub is 71.6 mm. If the wheel bore is larger, use 71.6 mm hub-centric rings. If smaller, the wheel will not seat.
- Thread and lug seat: Threads are M14x1.5. Match lug seat type to the wheel design (conical, mag, or ball seat). If unknown, consult the wheel maker.
- Offset and width: Use the calculator with ET 24 mm and 7.5 in as a known reference where applicable. Measure inner clearance at full lock and full droop if possible.
- Overall tire diameter: Keep total diameter change small to protect ABS, traction control, and gearing. Many owners target within about 3 percent of the OEM diameter shown on your placard.
- Load rating: Wheel and tire load ratings must meet or exceed the vehicle’s axle loads. Check sidewall load index and wheel spec sheet.
- Brake clearance: Spoke-to-caliper and barrel clearance must be verified with a test fit, especially with smaller diameter wheels or bulky calipers.
- TPMS: Plan for compatible TPMS sensors or sensor swaps and relearn steps.
- Backspacing: Verify with a straightedge and ruler if you are close to struts or inner liners. Source backspacing figures can vary by measurement method.
Plus Sizing And Common Upgrades
Plus sizing changes rim diameter and tire profile to maintain a similar overall tire diameter while widening the tread. Based on the listed 215/65R17, the overall diameter is roughly 28.0 inches. If your door placard shows a different OEM size, use that value as the baseline instead.
Guidelines for the 2008 Magnum:
- Use the calculator to keep overall diameter change within about 3 percent of your placard size to minimize speedometer and ABS impact.
- As width increases, consider slightly higher positive offset to protect inner clearance, or lower offset to avoid inner rub while checking outer fender poke.
- Confirm inner barrel clearance to brake calipers when moving to tighter spoke designs or smaller wheel diameters.
- For aftermarket wheels with larger hub bores, install 71.6 mm rings for vibration-free highway driving.
Installation Tips
- Park on level ground, chock wheels, and support the vehicle with jack stands at factory lift points.
- Clean the hub face and center pilot with a wire brush. Remove corrosion so the wheel sits fully flush.
- Dry-fit each wheel to confirm caliper and spoke clearance before mounting tires or installing all four corners.
- If using hub-centric rings, seat them fully in the wheel bore before mounting to the hub.
- Hand start all M14x1.5 lugs to prevent cross-threading, then snug in a star pattern.
- Tighten lugs with a torque wrench to the OEM spec from your owner manual. Re-torque after 50 to 100 miles.
- Perform a road test for vibration, rubbing on bumps and full-lock turns, and speedometer variance. Address issues before extended driving.
Tools And Helpful Supplies
FAQs
What is the bolt pattern on the 2008 Dodge Magnum?
It is 5x115.
Can I use 5x114.3 wheels on a 2008 Magnum?
They are not a direct fit. For safety and bearing longevity, use the correct 5x115 pattern. Adapters change offset and add complexity and are not recommended unless professionally planned and installed.
What center bore do I need?
The vehicle hub is 71.6 mm. Wheels with larger bores require 71.6 mm hub-centric rings. Wheels with smaller bores will not fit.
What lug nuts does it use?
M14 x 1.5 thread. Seat type depends on the wheel design; confirm with the wheel manufacturer or documentation.
What is the stock offset?
A listed OEM setup uses ET 24 mm on a 7.5 inch wide wheel. Your trim may differ, so verify your placard and use the calculator to compare.
Why do I see both 18 inch wheel data and a 215/65R17 tire listed?
Multiple OEM packages were used in 2008. Use the exact size on your door placard as the baseline for comparisons and speedometer calculations.
How close should I keep overall tire diameter when changing sizes?
Many aim to stay within about 3 percent of the OEM overall diameter shown on your placard. Use the calculator to check before buying.
How do I confirm if a specific donor wheel will clear my brakes?
Use the calculator for diameter, width, and offset comparisons, then physically test fit the wheel to verify caliper and spoke clearance. The tool cannot account for spoke geometry.
Where can I confirm OEM specs for my exact VIN?
Check the driver-door placard, the owner manual, and an official Mopar parts catalog or a Dodge dealer with your VIN for definitive wheel, tire, and TPMS details.
