So,..........you want to buy wheels for your 3g

The facts.

wheel bolt pattern: 4x100mm

Required offset: MINIMUM, NEVER LOWER 40mm*

*When do I have to have a offset higher than 40mm:
When you want to run 18" rims or when you want to run 215mm tread width on 16" rims

What tire size should I run:
If it's NOT listed, their's are reason.
The tire size's listed will NEVER rub, nor will any fender need to be rolled as long as the offset requirments are met.

14" 195/60-14
15" 195/55-15
15" 205/50-15 (195/50-15 not proper plus size, too short)
16" 195/50-16 (a tad taller at +2.0%, 205/45-16 is a better choice)
16" 205/45-16 (205/40-16 not proper plus size, too short)
16" 215/45-16 (a tad taller +1.7%, requires that you have 45mm offset rims)
16" 205/40-16 (Technically not a proper plus size, but not off as much -1.9%
17" 205/40-17 (215/40-17 a tad tall at +2.4% requires 45mm offset)
18" 215/35-18 (requires 45mm offset. NOTE: tire is 3.1% too tall)

What rims can I get on the cheap?
Any civic USDM civic or integra rim will fit. Newer civic's can come with 15" steelies. And 15" integra alloy's are a great choice.
