question about size and ET value

[peter]

I notice that the size from bold to bold is 114,3 mm, is that correct?
I also see sometimes values of +12, but what does this mean, in Europe we talk about a ET (offset) value of 35 or so.
That means that from the hart to the outside of the rim is +35mm, can anybody tell me what this +12 means or are that inches.
And will the different types of car years influence the rim size also.

one and the same.. the +12 is 12mm positive. the pic you linked to is a positive offset.

114.3mm is correct.

Chris and Carmon, thanks, but my last question, is it correct that the years that the fender size (front) change also effect the ET value?

Only if you want to put a much larger tire (>185) or you are concerned about the exact placement of the outside of the tire....either level or just inside the lip.

[peter]

Ok, and what is the normal ET value for 14" rims or 15" rims?
And which size tire belong to the 14 and 15" rim, for instance with a 185 tire.

I have 14x6 rims with 195/65's on there, +10 offset. I found 185's plowed with the U-20 set-up, meaning in hot cornering they just wanted to go straight. (understeer) but they were also not performance tires, I bought them out of desperation to get the car rolling, and got the std street series, which is 75, so they looked a bit "tractor-ish" on there.
