Offset Question
 

Can someone explain the difference between a 35mm and 40mm offset?

Yes, Tire Rack can..............

I was just reading that....but does that
 

mean a 40mm wheel would stick out further on the car than a 35mm?

I am looking to get new wheels and would like to have the wheel fill the fender better.

I believe the 20et wheel lip is closer to the curb than a 35et.....
 

allroad owners are limited to wheel type due to a 25 or 20et oem wheel. Many use spacers to allow 35 or 40et wheels to work. So the spacer is actually making the hub longer, reducing the offset of the wheel. Thinking through that, the lesser number is going to have more wheel to the outside.

good analogy

But flawed, I changed my number. Now I think I got it.

Thank you!

actually, it makes more sense if you realize that....
 

all the offsets we discuss are in fact NEGATIVE mm. We just forget the minus sign.

So as you go from -45 to -35 to -20 you are in fact increasing the offse5t of the wheel's centerline from that of the hub's mounting surface, which is the definition of offset.
