Car: 1993 Civic CX

Wheel: 15x6.5" w/ 40 offset

Question: Is that a good/bad thing? I dont really know much about offset and was wondering if anyone could give me some insight? Thanks guys... looking to buy some damn rims and I think were gonna stay with a smaller size cause even my damn steelies are heavy to me I cant imagine like a 17" or something :bloated:

depends though...
as far as i know, higher offset means the wheel is going more inwards.
Too much inward can cause rubbing the inside when you're making a turn, and too much outward can cause rubbing the outside of the wheel with your fender.
really depends on your suspension setting ....
good luck :cool:

AHHHHH HORSESHIT! :mad:

Anyone actually know anything that can help me? No offense Rich, just looking for a more informed source! :finger:

that offset is fine for a 15" rim.

That offset should be ok. a 15x7" wheel should be around 42-44mm. But since you have .5" less the 40mm offset should work.

what about +40 offset on a 16x7 wheel?

here's some good, basic info on wheel offsets (http://www.tirerack.com/wheels/tech/offset.htm)...

That may or may not rub. Reason being is that some companies might make a 40mm offset a 42mm offset whille others might make it 37-38mm offset. I'd get a 42mm offset to play it safe.

the difference between a 40mm and 42mm offset is less than 0.1in (the thickness of 2 pennies). i don't think these small differences matter...38mm, 40mm, 42mm--they're all basically the same.

i would agree with this, it sounds reasonable. how can the thickness of 2 pennies determine whether a wheel tire combination will rub or not? can anyone elaborate?

it's not about rubbing... it's about wheel thickness and the ability to make it fit.

you want the widest wheel possible for best traction. to help make it fit around suspension components and under the wheel well, you have to choose the correct offset.

with a 7 inch wheel, it's not much of a concern to keep it from rubbing the suspension components as it's pretty thin, and most honda wheels are 6.5 inches wide.

as for offset, the more offset, the more stress you put on your wheel bearings. in case you dont know, that is a BAD thing.


you stock wheels should be about -45-50 offset. if you want that "racecar" look and push them out to the edges, be my guest... but dont cry when they rub or a wheel flies off when your bearings go out after 20,000 miles.
