So I've got the tire size issue cleared up. Now onto rim sizes.

Rims say 16x7.5. What's the second number for?

Bolt pattern and offset say something like 4x100+43mm. Bolt pattern means four bolts by 100 what? and what does the offset number describe? What do I need for a G2 integra?

Thanks for your patience guys, one day I shall indeed understand your language.
