Offsets??
 

Ok I think that this section needs a chart that is easy to look at and contains all the info that would eliminate the posts about "Will this Fit?".

This is the best layout for the chart that I can think of and it just needs to be filled in.

Wheel Diameter
__16______17_____18
W_8___mm_8__mm_8 __mm
H_ 8.5__mm_ 8.5__mm_ 8.5__mm_
E_ 9__mm_ 9__mm_ 9__mm_
E_ 9.5__mm_ 9.5__mm_ 9.5__mm_
L_ 10__mm_ 10__mm_ 10__mm_
W_ 10.5__mm_ 10.5__mm_ 10.5__mm_
I_ 11 __mm_ 11 __mm_ 11__mm_
D_ 11.5__mm_ 11.5__mm_11.5__mm_
T_ 12__mm_ 12__mm_ 12__mm_
H_
**************Proper Offset***********

Then It should have a part at the bottom of the chart that says "Higher offset than reccommend will make the wheels stick out from the fenders Lower offset will make them sit more inside the fenders"
or vice versa

I think this would prevent people from wasting forum members times with answering the same pms or posts over and over again.

ok well for some reason the chart didnt hold the spaces in it so it just looks bunched up.

basically what I think it should be is like this

wheel diameter
then the list of widths with their proper offsets next to them

then what would happen if the offset was higher or lower than what is specified. ie sticking out

then how much offset change = 1inch
so if someone is putting on a wide body that add 1 inch they can know how much to add/subtract to make it fit the new width.

that still doesnt help me tho.
I dont understand that and thats why I feel we need a chart.

I want something that tells me if I want 10.5 wheels in the back I need 40mm and then what happens if its less like 20?

Will they stick out like crazy?

Im just throwing this out there and I think it would really simplify this subject.

Or people could just read about how offsets work (your view is backwards -- higher offset is more under the fender) at www.tirerack.com or a number of other places. And then read the wheel fitment thread in the archives.

Or you could use a reputable wheel vendor and listen to them about what will fit -- with the understanding that if they DON'T fit, they will be taking the wheels back and refunding your entire purchase....

Edit: Besides, the chart won't work, there are too many variables -- what type of suspension, alignment settings, etc.

Plus size moves the wheel in away from the center .& in from the fender ...

17" x 7" = + 28 - + 45 ?

17" x 8" changes

17" x 19" changes again

Read through everything but wanted to double check if this will work for my car.
Bolt Pattern: 5/114.3
2 Front Wheels: 18"x8" 2 Rear Wheels: 18"x9"
Offset: Front: 38 Rear: 40

this is for a 1995

It'll work, but buying the proper sized tires is a must. What's your suspension setup? Any springs/shocks/coilovers?

i have bilsteins (sp?) and H&R springs

You should be fine. For reference, I had 17x8.5 +37 up front with the same suspension setup and I didn't rub.

awesome, thanks for the info
