I assume we are talking posative(street side) offset here. Someone,correct me if I am wrong,but,the stock 16" wheels are 7" wide with 42 mm offset. The 18" rims you want are how wide? For reference 2 mm is the width of a nickle.

In one paragraph or less, it's the distance between the centerline of the wheel and the surface of the wheel that bolts to the hub. Positive offset means that mounting surface is closer to the outside of the wheel - as you see on front drive cars. Negative offset means the wheels are "deep dish" with the mounting surface closer to the inside of the tire. Wheels with zero offset have the mounting surface right on the center of the wheel.
Wheel offset is meaningful when you want to use wider wheels. A wheel that is one inch wider but with the same offset will protrude a half inch out farther toward the fender and a half inch inward toward the suspension. Add or subtract from the offset and that extra inch of width can be "moved" in closer to the center of the car or out further toward the fender.
If I screw this up, someone straighten me out. This is an example of swapping two types of Hyundai wheels from two different models.
My 2013 Elantra Limited came standard with 17x7" alloy wheels having a factory offset of 52mm. I removed them. In their place, I installed 17x6.5" 2006-2010 Sonata chrome wheels, having a 46mm offset. Or, as member @Airforce1 said, the offset width of 3 nickels.
This mod would have put the wheels slightly further out. But the Sonata's 1/2" narrower rim width brought everything back into line, pretty much, with the Elantra rims.
I can see an ever-so-slight widening in the stance. But, I'm OCD! The tires still remain tucked inside the fenders. So, no external cosmetic damage to the side fender panels/doors from flying road grit, etc..
Someone else can move this "offset subject" to the next level and discuss its effect on brake caliper clearance, steering components, and alignment issues. But for now, we'll keep it simple. Like baby steps. None of us learned algebra in kindergarten, right? I barely survived it in high school! :wink2:
40 will be fine, im running 35 now and ran 38 on the last setup. No spacers in back... but I may need to adjust my rear camber a bit more negative.... I "sometimes" scrape on the rear T.T
I love the way yours look yefeng, but I'm going to stay within mfg. recommended specs. I'll most likely go with an 18" x 8" 40 offset.
I like the looks of those Nexen N1000 tires you recommended. What size do you think would give me the best ride, and what kind of mileage rating do they have?
I am a personal friend with the owners of the largest tire dealer in SE Missouri. I used to service their burglar and fire alarm system before I retired, and got to know the owners very well. I plan on talking to them about new tires. They will give me honest answers without me having to worry about getting a big sales pitch. I might even get a little discount from them, you never know. :wink:
Thanks again...
You betcha! If it looks as good as I hope, I might make a video of it. :laugh:
