Wheel Guide/FAQ Thread
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.

Re: Wheel Guide/FAQ Thread
What is the smallest size wheel you guys can run on the si?
I have a Type R and cannot go lower that 15's, which is ok, but ideally i would like to run 13's for drag racing.
Wondering if the brake setup is different?

Nope, not going to work. Especially with Type-R brakes. I've had 14's before and they rubbed the caliper with out spacers. 14's would be the smallest you could go.

Re: Wheel Guide/FAQ Thread
well i use the tire calculator
cause i wanna know whats gonna happen if i get a bigger tires like 17's and right now im using the stock ones(ep3 15's)
and it appears that if i get the 17's with the same treadwidth and profile (195/60) its just gonna make the car slower by 8% and it will also affect my braking too
and i need some suggestions about tires im a little bit confuse
thanks in advance

Re: Wheel Guide/FAQ Thread
Well, to start off... you definitely wouldn't want to get 195/60's on 17" rims. I don't even think they make that size tire. Now, what exactly are you needing a suggestion on? Are you looking for anything in particular, or do you just want something that will look good? I am assuming you will be going with a 17" rim? Tell me the specs of the rim, then I can help you better with what tires you should use. Also, include a budget, what's the most you are willing to spend with wheels and tires...
Here's what I'm running if you would like an exapmle of a common set up; 17x7 +40 wheels with 225/45/17 tires. This is a difference of about 3.05% in diameter from the stock wheel and tire specs.

Here's a link with some really good info on wheel width and offsets. It was even written by a fellow HT member...

Re: question about wheels?
Psh, I would go 245/40 or 245/45 on the 9" wides and on the 8' wides I would go 235/40 or 45. I think you could even fit some 255's on the 9's with a little rolling. Curious, what wheels?

Re: question about wheels?
i agree. go as wide as possible as long as you clear. i know you can do 235/40 easy. i have seen 255 work as well, but may experience a little scrubing if no fender work is done. if it where my car, i would do either 235/40 or 245/40, if i could get everything to clear.

Re: question about wheels?
So, you are doing the wider wheels in the rear? I think you should put them in the front. Stagger for FWD cars is supposed to be reversed, in terms of performance at least. I also think that you would have better fitment with the wider wheels in front, but I could be mistaken... pretty sure though

Here's a link to the Reverse Stagger thread...

BTW, I'm moving this to the wheel guide/question thread at the top of the page. Good info in here for fitment...

However: Tire calculators and the resulting speed number that come out of them don't reflect how fast or slow they will make your car. They reflect the circumference difference of the respective tires. Your speedometer uses a preprogrammed circumference and multiplies it by the rotations of your tires to deduce your speed which is then displayed. If you increase circumference you increase the distance traveled with each rotation, so your speedometer will show slower than you are really going. and vice versa.
That doesn't necessarily mean that your car will be faster or slower, just shows an incorrect speed (and mileage).

Re: Wheel Guide/FAQ Thread
Well, more traction in the back would help with cornering. But only if the car oversteers. But everyone who knows a Honda would look at you funny for staggering like that.
