offset question?

The 20" wheels I'm getting are:
20X10 5-135mm 10

Now -- I suspect the "10" at the end of the number line means offset... Correct?
So these wheels have a 10mm offset.

Now--- What would my stock 02 Screw 17 inch wheels have for an offset?

What I'm wanting to know is will the 10mm offset make the tires stick out further to the ends of the wheels wells or will the 10mm offset make the tire not protrude out as far?

That might be the case.

If the offset is only 10mm, that is less then 1/2" of offset ( 25.4 mm =1" ).

I would think you would be more so worried about backspacing, then offset.

I found this URL via google.
http://www.rsracing.com/tech-wheel.html

The write up says you need to know backspacing to figure offset.

The L wheels I had on my '01 were 18" x 9.5" w/ 5.8" of backspace, and 14mm of offset, and on a 2WD they needed the larger wheel stops to stop the inner lip of the rim from hitting the bolt holding the brake line on.

If I were to take a guess at the backspacing on the wheels you are looking at, with the chart, I would say they have a 5.9" to 6" backspace. This almost seems a wash between the 9.5 wide wheel with 14mm offset to 10" wide with 10mm offset ( check my math, to make sure I did it correctly ).

These wheel were stil inside when viewed from the top down, but from where the wheel well curved in, they stuck out. I would guess you are going to be about 1/4" outside the wheel well, agian guessing by what the backspace is, and if I did my math correctly.

The backspace and offset ( if Pos ) are meant to try to keep more of the wheel inside the wheel well opening. This is where the 4 x 2 had an isssue with the lip of the rim hitting the bolt for the brake line, pushing it too far in, at steering lock, it would rub.

Neg offset will push the wheel outside the wheel well.
