Rim sizing - what size to get for OE equivalent? - Toyota Yaris Forums

I'm rather clueless when it comes to the rim sizing convention

My mission is to buy a set of standard steel rims for my Yaris, for winter tire use. I'd like to keep things simple, and buy rims identical in size to the OE ones, and mount winter tires in the identical OE size (i.e. 175/65R14).

My problem is I can't seem to figure out how rim sizing works. I looked up the Wikipedia page (http://en.wikipedia.org/wiki/Wheel_sizing) but I'm still confused.

All I know for sure is that I need 14" diameter, 4 bolt, 100mm bolt circle rims. I have no idea what the offset or centerbore is. As a related question, does the so-called "multi-fit" rim mean that it won't fit the wheel hub exactly, whereas a clone OEM spec rim does? If so, I'd rather pay the extra CAN$5 per rim to get ones that actually fit the wheel hub (and therefore not put all the load on the lug nuts).

The manual simply lists the wheel size as "14 X 5J". What does the "5" and "J" mean?

I've yanked off the wheel cover and checked for any markings on my existing rims. They have "J 14X5J DOT 9 05 /SDK 1" stamped on them. Is this what I need to make sure to get?
