Biggest rims on n Eclipse?

yeah i forgot to ask whats the biggest size rim you can fit on an eclipse, they have really big wheel wheels so... maybe 19 hopefully 20???

I know someone with 19s, but I don't think 20s will fit. Here is someone on 19s:

yes 19,20's wont fit.

For ever inch on rim you increase, decrease the series of the tire by 5. Example...
The RS comes with 14" 195 60's

A 215/40/17 is the exact same overall diameter
A 215/35/18 is the exact same overall diameter
A 215/30/19 is the exact same overall diameter

Dont think you can get a 25 series 215 to fit a 20 but I am pretty sure that you could fit a 215/30/20. Now I dont know why in the hell you would want to and please dont show it to me, but there is how you can tell the overall diameter.
