I've been trying to understand how the offsets work in terms of understanding what will and what won't. After trying to figure it out, I figured I'd post up and see if I can get some help.

My friend is trying to sell his Stern ST2 wheels and I want to know if they fit. They are 19x8.5 in the front and 19x9.5 in the back. The only problem I'm having is the offsets. Now he doesn't know the exact offset for these wheels, so I went online and found the different offsets that they have available and here they are:

Front: 20, 32, 38
Rear: 25, 35

Now I know that the fronts for this size rim are supposed to be +58 minimum or +63 depending on the tire size. And for the rears, +50 and +55. I have no clue what any of this means, so if anyone can help me I would greatly appreciate it. Thanks!

 

means it won't fit. it will stick out past the fender.

the lower the offset, the more it sticks out.

 

Here's a good wheel offset calculator that shows how wheel offset and wheel width affect the positioning of the wheel.

 

The offsets you list won't even be close.

 

Let me jump in and say "Don't do it!" too. Those offsets you mentioned would be suicide!
