I'm wondering what the biggest size of rims and tires I can fit on an Evo 3 with coilovers, doesn't matter if I need spacers or anything I just want to know if 18x9 would fit with 245/40/18 or not and what offset I would need without rollin fenders.

 

I highly doubt you can fit 18" rims or 245 rubber in III's tiny fenders

I think 17"/ 225 would be maximum

 

What about a 17x9 with 225 40 17 tires?

 

Evo3 stock size 205/60/15 so probably 17 is biggest you can fit if that.

 

215/45 /17
