***OFFICIAL 8G Wheel & Tire thread***
Same as the others.
I'll start with what I know:
Stock rims: 17x7
23-25 lb
Let's get a list of all the relevant limits (offset, wheel width, tire size) for the 8th gen. I want people to come in, see the thread, and leave with a good idea of what they can buy without having to ask n00b questions that get covered over and over. (like my thread
)

Rough guidelines:
PCD: 5 x 114.3
Rim diameter limits: 16-20"
Rim width limits: 7-9.5"
Rim offset limits: +55-+20 mm *
Examples:
Mugen GP's: 18 x 7.5 +48 mm
Example of flush: 17 x 9 +35, 17 x 8.5 +30, 18 x 8.5 +32, etc
*Dependent upon width of wheel

Hi, I wanted to find out what is the maximum width I can put on my 2008 Honda civic si sedan? I want to put on a 17x10,the available offsets I can go with is +12,+25,+35. I'm unsure if a 17x10 will even fit on my car. Any info if this size can possibly fit on my car with any of the offsets and without having to do any fender mods or rubbing issues? Plus, I'm going to lower my si sedan with Eibach sportline springs. If a 17x10 doesn't fit,I'll probably put a 17x9 with an offset of either +35 or +43. I've seen members rides with a 17x9 on Si sedans so maybe that could work. The reason I want 17x10's is because the brand I want has a concave look in that size and I also want a flush look too...
What wheel in particular are you considering?

Will 17X9 +35 rpf1's fit. Im on HFP suspension and my buddy is getting rid of 2 rims from his ep3 because they dont fit his car to well. If I got another 2 same size would i run into clearance problems...i just have the HFP suspension, no camber kit, etc...
sweet thanks im getting a good deal from a friend of mine for 2...so im gonna buy the other 2 from tire rack...any idea what the fitment is for...Evo? Miata?

you will not be able to fit a 17x10 +35 without fender rolling/pulling, rubbing, or major camber; let alone trying to fit a 17x10 +12 or +25.
your best bet is to go with the 17x9 +43/+45 with some fender work, camber, and proper tire size. 17x9 +45 is concave in certain wheels depending on what you are looking for.
to give you an idea...i was lowered on comptech springs with 17x8 +30's with -2.3 camber in back and rubbered w/o fender work. i could of gone with a smaller tire, but i hate stretching tires. could of ran maybe -1.5 w/ completely rolled fenders (not a mild roll)

You're dreaming.....8.5" max I say. Especially if you will be lowered. 10" is out of the question.
Maybe you could get the 9" on there if you put a tire on that has a smaller than stock diameter which will give more clearance fron the inner and outer fender.

This thread will be a work in progress, and please post your questions and requests for more/other information to be added in here. Or, if you know something to be true of false that should be noted in this thread, please feel free to do so.
The information below is not chassis specific.
Here is some information to consider when making a wheel selection for your vehicle.
All of this information is available online, and a lot of it in this post is copied from other websites, just so you know
OFFSET
The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types (measured in millimeters).*
Zero Offset
The hub mounting surface is even with the centerline of the wheel.
Positive
The hub mounting surface is toward the front or wheel side of the wheel. Positive offset wheels are generally found on front wheel drive cars and newer rear drive cars.
Negative
The hub mounting surface is toward the back or brake side of the wheels centerline. "Deep dish" wheels are typically a negative offset.
If the offset of the wheel is not correct for the car, the handling can be adversely affected. When the width of the wheel changes, the offset also changes numerically. If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside. For most cars, this won't work correctly. We have test fitted thousands of different vehicles for proper fitment. Our extensive database allows our sales staff to offer you the perfect fit for your vehicle.
*Backspacing, similar to offset, is the distance from the hub mounting surface to the inside lip of the wheel (measured in inches).

These are very useful calculators that will give close estimates of difference in wheel offset, and tire sizing recommendations...

Additional Information:
Start your search for new wheels by picking the tires first. Get the tire manufacturer's rim width recommendations and physical dimensions for the tires you want. Pay close attention to Section Width and Measured Rims specs, these are important numbers to be used when selecting rims and determining vehicle fitment.
Bolt pattern or lug pattern or bolt circle is determined by the number of bolt holes and the bolt circle diameter.
Hub Diameter or center bore is the hole at the center of the wheel.
Rear spacing or back spacing is the distance from the backside of the wheel mounting pad to the outside of the rim flange.
Bead-Loc: A device which captures the tire bead between it's flanges, usually secured by bolts to keep tire bead from dismounting. Usually used in dirt circle track or off road applications where low tire pressures are used and hitting ruts or other vehicles are common.

Found this from the DC5/EP3 thread.
Heres a pic just to give you an idea..
^thats because you have stretched tires. the fg1 doesnt have stretched tires therefore he rubs. as for fitment for you, arent those ekora's wheels off of 8 th? or did you copy his wheel size?
He sold those wheels, and yes that was what made me go for that fitment.His were polished. I could have gone 235 all around with a +35 if I wanted, but I like this better.
Apparently you know your ****, so let's see this ****.
when i get home ill post pictures
Wow!! Sounds like i'm getting mixed opinions on what I can put on my Si sedan. Thanks tho for the input everyone. I think I got the size I want narrowed down to a 17x9 maybe, just not sure which offset to get, the +35 or +43? Like I said in the 1st post, I'm going to be lowered on eibach sportline's and using a camber kit. I even heard that springs will not work for this set-up, I would need coilovers to have wider wheels on my car? Is this true?
Hey guys. Trying to help out a friend of mine.
He owns a black '09 Si sedan and he's looking for a set of wheels. Preferably black 18"s with a red lip/band. Now he's not a baller so Volks and the like are a no.
So far he's really interested in these:
Ok, he's thinking about getting these (Kazera KZ-K), but I never heard of the brand. Are they decent or are they crap like Rota or what?
18", 45 offset, 23lbs each

Link --> Kazera on TireRack
Any help would be appreciated. Thanks guys.

Tirerack is reputable vendor and I have heard of this brand before. I'd suggest an offset that's little lower, preferably below 40 mm if he's going with anything wider than 7.5 inches.
Heres a price comparison.
17x8 Work Emotion CR Kai- $1600
17x8 Drag DR-31(Emotion Copy)- $480ish
They tend to break in 2 when you hit a SERIOUS pot hole. But I've had Rotas and Drag wheels, and never had that problem. People just talk a lot of **** about them because they're replicas.

I just found this on a VW site.
If you think Rota's are poorly made, crap wheels... then you know nothing of their history.
Ever hear of PAWI?
"Rota, as we know it today, was "Rota Italia" years ago... Philippine Aluminum Wheels Inc. (PAWI), was established on October 8, 1976 as a joint venture between FPS of Italy and Romeo S. Rojas to engage in the manufacture of alloy wheels in the Philippines.
The company's first production of its Rota brand of wheels was in 1977, with an initial production capacity of 4,000 wheels a month. In just the company's first year, Rota wheels are chosen by Chrysler-Mitsubishi (Philippines) as OEM (Original Equipment Manufacturer) for its vehicles passing through the stringent OEM specifications of its parent company in Japan.
The following year saw other major car assemblers engaging the services of the company to manufacture their OE wheel requirements for their vehicles. These companies included Ford, Datsun, Isuzu, Mercedes-Benz, Opel and Volkswagen.
In 1983, after seven years of operation, PAWI became a 100% Filipino corporation. It also marked the year that Japanese technology was introduced into the company's manufacturing operations.
In 1988, PAWI develops its "magnesium-strengthened, heat treatable alloy," making Rota wheels lighter yet stronger and more durable. The following year saw a major upgrade of facilities as PAWI introduced state-of-the-art technological improvements in the form of the latest equipment and machines that speed up and improve chemical analysis, machining, painting and finishing. With the comeback of Toyota into the Philippine market, they chose Rota wheels as their OE wheels, as well as Daihatsu.
In 1990, a milestone was met when PAWI hits a record production of 20,000 Rota wheels per month.
Today, PAWI produces alloy wheels of world-class quality, using state-of-the-art technology. A new series of upgrading has since boosted its production capacity to new heights of 50,000 wheels a month. More than ten times of its capacity when it first started."
