Help offset size??? I need a little help here. I've been searching but cannot find what I am looking for. I have a 2012 45th 2ss car with the factory 45th wheels on it. 8"*20" front and 9"*20" rears. I need to know does anyone know or know how I can find the offset of these wheels? I am looking to get different wheels but I am finding most are asking what offset do I want? I want the wheels and tires to move outward a schoch to get the wheel to not be so tucked under the car. i am looking to go 9" up front and 10" wheels out back for my daily driving wheels. I like the way the ZL1 wheels and tires sit on those cars. I know they are wider wheels.
Thanks Rob

Your current wheels have a +35 for the 20 x 8s, and a +40 for the 20 x 9s.
Here's some good options:
front
20 x 9, +30 to +20 offset
20 x 10, +35 to +25 offset
rear
20 x 10, +35 to +20 offset
20 x 10.5, +40 to +25 offset
Tires
Front
20 x 9, 245/45/20 .. 255/40/20 .. 255/45/20 .. 265/40/20 .. 275/40/20
20 x 10, 275/40/20 .. 285/35/20 .. 295/35/20 .. 305/35/20..
Rear
20 x 10, 275/40/20 .. 285/35/20 .. 295/35/20 .. 295/40/20 .. 305/35/20
20 x 10.5, 275/40/20 .. 285/35/20 .. 295/35/20 .. 295/40/20 .. 305/35/20 .. 315/35/20

Sweet Thank You! But one more question. Can I use the stock tires that are on the car now when I go up to a 9" and 10" rim from the 8" and 9"?
Stock tire sizes are.....
Front 245/45 ZR20
Rears 275/40 ZR 20
I don't want to have to buy new tires yet as these have only 6000 miles on them in over a year and a half. If so are they going to look goofy or wrong? I see you say I can use the stock rears on a 10" rim but the front tires are not in the catagory you listed for the 9" fronts.
Thanks again Rob

Yes you can. Most tire manufactures recommend up to 9" wide wheel with a 245/45/20.
With the 275/40/20 tire you can run it on up to a 10.5" wide wheel, and so manufactures recommend up to a 11" wide wheel with their tires.
FYI, with the 245s on a 9" wheel you'll need to be more careful pulling up next to a curb. I forgot to add the 245/45/20s(and a few others) to the list that's all.
