Please post a listing of your rim size, offsets and tire size. I spent the last three weeks researching offsets and rim sizes and I wish this thread existed before I ordered my rims. Make sure to include tire size too! This is the approximate equation for determining fender roll. Fender roll > 4" Outer > No fender roll.

Here is a list of offsets that I have found on this site along with links to pics where possible, so you can see what they look like. Feel free to add to or make corrections to the list. The links are under the rim size category and the numbers are rounded for my sanity.



Rim Size.........Offset.......... Stock+........... From Center Out

10.5"/19"........(+22).......... 1-9/16" ........... 4-7/16"
10.5"/19"........(+24).......... 1-1/2" ............. 4-5/16"
10"/19"...........(+18).......... 1-5/16" ........... 4-5/16"
09.5"/19"........(+12).......... 1-5/16" ........... 4-1/4"
10.5"/19"........(+30).......... 1-1/4" ............. 4-1/16"
09.5"/19"........(+19).......... 1-3/16" ........... 4"
09.5"/19"........(+22).......... 1-1/16" ........... 3-7/8"
10.5"/19"........(+34).......... 1-1/16" ........... 3-7/8"
11"/19"...........(+40).......... 1-1/16" ........... 3-7/8"
10"/19" ..........(+29).......... 1-1/16" ........... 3-7/8"
09.5"/19".........(+24).......... 1"................... 3-13/16"
09.5"/19".........(+30).......... 3/4" ............... 3-9/16"
10.5"/19".........(+43).......... 5/8" ............... 3-1/2"
09.5"/19".........(+35).......... 9/16" .............. 3-3/8"
09.5/19" .........(+38).......... 5/16" .............. 3-1/4"


Note 1: Stock+ is how much farther out towards the fender the rim is compared to stock.
Note 2: From Center Out is how much of the rim is outside of the hub face.
Note 3: Some of these are also shown in 18's. This is rim size only.
Note 4: Tire size can also make a big difference in how and whether the wheels fit without rolling the fender.

Thanks! That information is very useful!

don't forget to include the 18" sizes. some do go for that size as well

18 x 8.5 +25 offset, tire size 245/40

18 x 9.5 +30 offset, tire size 275/40

those are the LMGT-4

ether

Just to be clear, the above table is for the rear.

the (09.5"/19"........(+19).......... 1-3/16" ........... 4") actually should be +18mm offset, i have the exact same spec as Durso

For the front:

I think the max in the front is a 9.5 +25mm, that is at the max both at the fenders edge and on the inside suspension piece. anything within that parameter should work

Yes, the above table is for the rears only. Thanks for the correction ether. I wish I could go back and edit it.

Z04, I could find very few pics of 18's with posted or known offsets. If you find any please add links to them. I will continue to add to this thread as I find them. I just thought I'd get the ball rolling and maybe help some people out.

Also, if anyone else posts could you add if you are lowered or not.

Thanks everyone for the replies. And please add corrections if you find errors.

Good chart - looks accurate. Should work for fronts and 18s too. If comparing to stock 18s which are 8" wide and have an offset of +30mm on both ends. If using for fronts, the wheel width should go down to 8.5". The LMGT4 that you link to above are 8.5" front +25mm and 9.5" rear +30mm.

Again - Good Job!

After all that I posted my own offsets wrong!

10.5"/18" ...........+30 .............1-3/16"..........4-1/16"

I will have pic this week of my setup of 295/35/18's in the rear.

DURSO

That is true +18 offset front 8.5 and rear 9.5
2.5" lip front 3.5" lip rear.
19"

Thanks for the correction DURSO and ether. I think that offset is perfection. I have a 10.5 @ +30 which is the same outer size as 9.5 @ +18.

DURSO and Ether's rear offsets - (and mine now )

zillinois,

what width are you running up front?

zillinois

iTrader: (6)

My plan is to run 275/35/18 up front on 9.5" rims. But I have to see if the 295's fit to my satisfaction in the rear. If they don't, then I'll probably switch to a 285/35 on back and 265/35 on front. Also, I want to see how the 30 offset looks on the 10.5's to determine what offset to use on the front. When I'm done with the front I'll post a similar chart for the front rim sizes and offsets.

Upfront, they had to go BBS RG755 18x9-in. 42mm offset, 12mm spacer because 9.5 stuck out of the fenders, but the big thing was to ensure the BBS wheels fit over the brakes.

Ideally, I want to go with the following as well:

275/35/18 F 18x9.5
295/35/18 R 18x10.5

Maybe 9" and a 265/35 would be better. That's why I waited to order the front rims, because I'm pushing the limit and want to make sure I get it right. The SCC car would have an offset of 30 on a 9" rim. My rear wheels come tomorrow, so I'll know more then. I'll have to re-read that article because I thought they were running 9.5's?!?

igor@af

That was my understanding too.. but it doesn't seem like it now that I re-read the stuff.

I KNOW that 9.5 fit up front, others have done it, but I can't recall the offset or the wheel brand (I have 14" StopTechs) or whether spacers were necessary.

Personally, I don't mind the front wheels sticking out a bit as I will do some lame fabrication to flatten the lip or get wider front fenders.

Here is my 18" x 10.5" with 295/35/18's rear offset 30. I will be ordering my fronts this week to complete the setup. But here are a few offset shots. If I had to do it over again, I would have got a 33 offset. I know that's being extremely ****, but the rims do stick out just a bit more than I like. (Would I be able to notice 3/16ths of an inch? Probably not but I would know its there.)

I have no problems with rubbing and will not have to roll the fender. I am still thinking about springs with a mild drop. I think it can handle a .6" drop.
