2008 Honda Civic Si Rims: Factory Fitment & OEM Replacement Guide
Finding replacement rims for a 2008 Honda Civic Si starts with identifying the exact version and original wheel. Honda's US 2008 Civic Si sedan factsheet lists 17-inch alloy wheels and P215/45R17 87V all-season tires, with a separately listed summer-tire option. That does not make every 17-inch Honda-style wheel interchangeable.
This guide separates the documented sedan specification from the checks needed to buy a matching replacement. For a coupe, special edition or modified car, confirm its own original equipment rather than extending the sedan factsheet to it.
2008 Honda Civic Si OEM Wheel Specs
| Item | Documented US Si Sedan Specification or Purchase Check |
|---|---|
| Wheel diameter/material | 17-inch alloy |
| Standard tire | P215/45R17 87V all-season |
| Available summer tire | 215/45ZR17 91W, as listed in Honda's factsheet |
| Width, bolt pattern, offset and center bore | Confirm against the exact original wheel part number and vehicle application before buying |
| Lug hardware | Confirm thread, seating surface and installation requirements for the exact wheel; do not select by thread alone |
The Honda factsheet substantiates the diameter and tire entries, not a universal bolt-on specification. Our recommendation is to ask the seller for exact part-number compatibility rather than accept an approximate offset match.
Why the Center Bore and Offset Matter
Include bore and offset in the compatibility check, along with width, bolt pattern, hardware and brake clearance. Do not use a generic tolerance or a promise that hub rings will cure vibration as purchase approval. Ask a qualified installer to resolve any difference from the original wheel before ordering.
OEM vs Replica Rims for the Civic Si
You can compare an original-equipment replacement with an aftermarket alternative, but assess the specific wheel rather than its label alone.
Genuine OEM Wheels
For a single replacement, request the part number and compare the spoke design and finish with the other wheels. A used OEM wheel still needs a condition and application check; previous use or refinishing should not be assumed from a stock photo.
Replica Wheels
A similar design does not prove an exact finish or fitment match. Ask for the manufacturer's vehicle application, specifications and required hardware. Do not assume an alternative is lighter, heavier, cheaper or inferior without evidence about that product.
At OEM Wheel Shop, use the individual listing and vehicle details to evaluate an OEM replacement. Resolve unclear specifications before purchasing.
Common Fitment Questions
Will 18-inch wheels fit a 2008 Civic Si?
A diameter alone is not an approval. Have the exact proposed wheel-and-tire combination checked for your version of the car; this guide does not prescribe an 18-inch conversion.
Do 2006–2011 Civic Si wheels interchange?
Do not buy solely on that year range. Confirm the original and replacement part numbers, application and finish for the exact vehicle.
What tire size goes on the factory 17-inch rim?
The US 2008 Si sedan factsheet lists P215/45R17 87V all-season and an available 215/45ZR17 91W summer tire. Verify the vehicle's specified equipment and tire requirements rather than copying only the diameter.
Can I run wheels from a non-Si Civic?
Do not assume a Civic badge or shared model year establishes compatibility. Obtain an exact application check before using another trim's wheels.
When a Civic Si Wheel Needs Replacing
Do not classify all curb rash as harmless by appearance. The US Tire Manufacturers Association's care manual, chapter 2, page 21, explains that wheel damage can be difficult to see and should be checked professionally with measuring equipment.
- Surface scuff: have the impact and condition assessed before choosing cosmetic work.
- Bend or crack: stop using the affected wheel and arrange professional assessment.
- Leak or vibration: have the wheel-and-tire assembly checked rather than guessing the cause.
- Corrosion: ask the installer to assess the affected areas before deciding whether the wheel is serviceable.
Understanding the Factory Finish and Weight
Compare clear photos, the wheel markings and the seller's description with your remaining set. Ask whether the wheel has been refinished and what finish is actually offered. If weight is important to your choice, request a measured value for that specific wheel rather than relying on an OEM-versus-replica generalization.
How to Order the Right Wheel
- Identify the vehicle. Record the year, body style, trim and any known modifications.
- Record the original wheel. Photograph the design and identifying markings for a part-number comparison.
- Check the exact listing. Confirm application, condition, finish and required hardware.
- Plan installation. Have unresolved fitment questions checked before purchasing.
Browse OEM Wheel Shop's wheel catalog and check the individual application. That collection covers multiple vehicles; its presence does not verify a Civic Si fitment.
Installing Your Replacement Wheel
Use the instructions and correct hardware for the exact vehicle and wheel. Have a qualified installer confirm the seating surface, tightening procedure, specified torque and any follow-up requirement; this guide does not substitute a generic lug-seat type or recheck interval for those instructions.
Ask the installer to assess the tire, wheel condition and balancing needs as part of the job. Do not assume that a particular balancing service will resolve damage or an incorrect fitment.
Bottom Line
The documented US 2008 Si sedan setup provides a starting point, not an interchange guarantee. Match the actual vehicle and original part number, check the offered wheel's condition and finish, and verify installation requirements before ordering.
