need help about rims sizing

18x11.5. -15 offset is equavilent to what size in 19 .... i cant find the thread that once posted about sizing comparison on here.... so please shed some light on this guy

An 18 inch wheel is not equivalent to a 19 inch wheel. What are you asking?

[Oh Damn, it's Sam]

Yeah, equivalent in what way?

Width is width, offset is offset, neither are affected by the diameter of the wheel.

i remember somewhere ... 18x11 with negative offset is like 19x9.5 with higher offset ... maybe ? who knows...

[Oh Damn, it's Sam]

Again, equivalent in what way? What exactly are you trying to figure out?

The positioning of the wheel in the wheel well in terms of poke/sunkenness is related to both width and offset, and two wheels with differing widths and offsets can sit the same. For example, 25mm more offset will make a 2" narrower wheel sit the same as one with 25mm less offset and 2" wider. Diameter does not play into this, though.
