Whats the offset for the ITR and Prelude? 40 for the ITR and 48 for the Prelude?

The thing is I want to get some 17" wheels that I where I can swap them back and forth. I usually only drive the ITR in the summer and Prelude year round. What offset can I get that will be adaquate for both cars.

Also is the lower the offset the more it sticks out?

 

The offset for many Honda/Acura wheels are 45.

The offset of a wheel is what locates the tire and wheel assembly in relation to the suspension. More specifically, it is the measured distance between the hub mounting surface and the center line of the rim. Below is an explanation of the various types of offsets.



Positive Offset:
A positive offset occurs when the hub mounting surface is on the street side (the side you see) of the center line of the rim. Most factory rims will have this type of offset.

-----



Zero Offset:
When the hub mounting surface is centered within the rim, it is known as a zero offset.

-----



Negative Offset:
If the hub mounting surface is on the brake side of the center line of the rim, it is considered a negative offset or "deep dish".

Note that extensive negative offset can potentially cause increased steering wheel kick-back and place additional stresses on the vehicle's entire suspension.

Heh, "deep dish" should describe a pizza, not wheels on a Honda.

To add some info to the thread, I'm running a 42 offset on my 2000 gsr, and with a 205/45-16, I'm about 1mm from needing to roll the rear fenders. Plenty of front clearance with that low of an ofset, so much so that I'm looking into spacers, but I've also got &gt; 2* front camber from the 3" drop.

 

Would I steel go with a 42 offset for my ITR if its for 17"? Also whats the offset for the prelude with 17"?

 

The stock ITR offset is +50 at 6" wide, dont forget that width and offset go hand in hand a +50 at 6" is NOT the same as a +50 at 7" and so on...

With positive offsets (see excellent definition posted by Johnny above), the smaller the number, the more it sticks out from the car; the larger the number, the closer the wheel is to the inside of the car.

When comparing wheels of different widths and/or offsets, the wheel offset calculator whose link Koala just posted in another topic (thanks!) may come in handy...

So I was right? Where does it start off at? Then a 40 offset will stick out more than a 50 offset?

I don't understand either question.

Yes, assuming that both wheels have the same width. If they're not the same width - and they probably aren't - then it depends on the difference in width.

Meaning if the most that it sticks out is 0, what is the most its in? Its just something Im wondering.

 

Have you tried playing with the wheel offset calculator (see link above)? That may answer your question.

In addition to the stock ITR wheel width (6) and offset (+50), you will need to know those numbers for the stock Prelude wheels. You can then play around with widths and offsets for the hypothetical 17" wheels you're considering and see where they sit, relative to the stockers.

 

Does anyone know what the offset of Prelude stock wheels, they're 16".
