Recorded OEM specifications for the 1999 Dodge Viper, donor years with overlapping ranges, and a calculator to compare a selected wheel. Range overlap is not a guaranteed fit.
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.
Center-bore records disagree: year-level hub 71.5 mm vs trim range 71.6–71.6 mm. Interchange below does not treat this as an unqualified match.

These are vehicle-year records whose recorded OEM ranges overlap this 1999 Dodge Viper. Overlap is not a guarantee that a specific wheel will install. Selected-wheel comparison is in the calculator below.
Evaluated 25 donor years. Listed 24 eligible overlaps (not all evaluated years are compatible). Showing all listed.
Years grouped because recorded compatibility evidence is equivalent. Each year keeps its own page.
Center-bore records disagree (target year-level hub 71.5 mm vs trim range 71.6–71.6 mm; donor year-level hub 71.5 mm vs trim range 71.6–71.6 mm). Unqualified overlap is not claimed until the conflict is resolved.
Lug thread is not fully recorded for this comparison. Hardware must match the 1999 Dodge Viper studs and the selected wheel’s seat. Unknown hardware is not a match.
Bolt pattern data is incomplete for a full interchange decision.

The following specifications are the known reference values supplied for the 1999 Dodge Viper. They may vary by trim, package, axle position, replacement wheel, or market. Confirm the vehicle identification number, original wheel markings, and OEM service information before purchasing wheels or tires.
| Specification | Known value |
|---|---|
| Bolt pattern | 6x114.3, meaning 6 studs on a 114.3 mm pitch circle diameter |
| Center bore | 71.6 mm |
| Thread size | M12 x 1.25 |
| Reference rim diameter | 17 inches |
| Reference rim width | 10.0 inches |
| Reference wheel offset | ET51, or 51 mm |
| Reference backspacing | 7.01 inches |
| Reference tire size | 275/40R17 |
The listed 275/40R17 tire has an approximate calculated overall diameter of 25.7 inches. Actual mounted diameter can vary by tire brand, tread design, inflation pressure, and measuring method. The supplied data does not establish whether these specifications apply identically to every 1999 Viper trim or wheel position.
Do not assume that a wheel fits because it has six lugs. The wheel must also match the 6x114.3 bolt pattern, clear the brake and suspension components, use a suitable center bore, and provide safe thread engagement with the correct hardware.
Use the calculator to compare a donor vehicle's wheel and tire information with the 1999 Dodge Viper reference values. Enter the donor vehicle under “Wheels from” and enter the Viper under “Installed on” or use the known values above when the vehicle record is incomplete.
The calculator is a comparison and screening tool, not a substitute for physical clearance checks or OEM approval. It cannot verify every brake-caliper, suspension, fender, tire-load, or hardware issue.
Before ordering a wheel or tire package, confirm the following details for the exact vehicle and wheel:
Wheel spacers, adapters, and unusual lug hardware can change safety and clearance requirements. Use them only when specifically approved for the application and installed according to the manufacturer's instructions.
Plus sizing means increasing wheel diameter while reducing tire sidewall height so the overall tire diameter remains close to the reference size. The calculator can help compare these changes, but it does not confirm that a proposed package is safe or legal.
Changing from the 17-inch reference wheel to another diameter can affect ride comfort, wheel protection, steering response, gearing, speedometer accuracy, braking feel, and clearance. A wider tire or wheel can also contact the inner suspension, outer fender, or bodywork even when its calculated diameter appears suitable.
Do not select a tire solely by matching section width. The approved rim-width range, load index, speed rating, tire construction, and vehicle clearance must also be checked. If the correct trim-specific OEM data is unavailable, use the original wheel and tire markings plus the owner's manual, service information, and a reputable tire or wheel professional.
Inspect the hub, studs, wheel mounting surface, and replacement wheel before installation. Remove rust, dirt, paint buildup, and debris from the mating surfaces without damaging the hub or wheel. Never use the lug nuts to pull a misaligned or incompatible wheel onto the vehicle.
Install the wheel by hand-starting every lug nut. Tighten in a star pattern in stages, then apply the OEM-specified final torque with a calibrated torque wrench. The correct torque value is not provided here and should be taken from the Dodge service information, owner's manual, or wheel manufacturer's instructions for the exact hardware.
After installation, rotate the wheel by hand and inspect for interference. Lower the vehicle, recheck torque, and follow the wheel manufacturer's retorque guidance after initial driving. Stop immediately if there is vibration, rubbing, steering change, loose hardware, or loss of tire pressure.
Maintain the tire pressure specified for the vehicle and verify that the tire pressure monitoring system, if equipped, is operating correctly after the wheel change.
Useful equipment for a careful wheel-fitment inspection and installation includes a calibrated torque wrench, a suitable socket, a jack and properly rated jack stands, wheel chocks, a tire-pressure gauge, and a tread-depth gauge. Use equipment rated for the vehicle and follow safe lifting points from the service information.
What is the known bolt pattern for the 1999 Dodge Viper?
The supplied reference is 6x114.3. Confirm the pattern on the exact vehicle and wheel before purchase.
What center bore is listed for this Viper?
The known center bore is 71.6 mm. A replacement wheel with a smaller bore will not fit over the hub. A larger bore may require correctly sized hub-centric rings, subject to wheel and manufacturer requirements.
What wheel size is listed as the reference fitment?
The supplied reference is a 17-inch diameter wheel, 10.0 inches wide, with ET51 offset and 7.01-inch backspacing.
What tire size is listed?
The supplied reference tire is 275/40R17. Tire approval, load rating, speed rating, and clearance must still be verified for the exact vehicle and position.
Can I use wheels from another vehicle?
Possibly, but no donor-vehicle compatibility list is provided here. Use the calculator to compare the donor wheel's bolt pattern, center bore, diameter, width, and offset. Then confirm brake, suspension, fender, tire, load, and lug-hardware compatibility in person and with OEM or wheel-manufacturer information.
Does the calculator guarantee that a wheel will fit?
No. It provides dimensional comparisons and allows custom wheel and tire inputs. It cannot guarantee brake-caliper clearance, suspension clearance, fender clearance, hardware compatibility, load capacity, or legal compliance.
What happens when I change the rim diameter in the calculator?
The calculator updates the tire diameter in the comparison. Review the resulting overall diameter and sidewall change, then verify the tire's approved rim width and the complete package's physical clearance.
What lug hardware should be used?
The known thread size is M12 x 1.25. The lug-nut seat style, stud or nut application, thread engagement, and final torque must be confirmed for the exact OEM or aftermarket wheel. Never assume that the thread size alone makes hardware compatible.
Wheel interchange depends on more than bolt pattern. Where data is available, this site compares recorded OEM values:
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.
