Im a first timer. both in this forum and with my 05 civic DX, SDN. [stock no mods] I'm thinking about new rims [sport edition cd 16x7.5] and tires. The rec. tires are 205/50-16. But i would like a larger footprint so if i go with a 215/50-16 or even a 225/50-16 [which is my preferance]. would i have any problems with rubbing, suspention, brakes or is this too much to ask the 1.7ltr. motor to turn? I would like to make this happen and would appreciate any advice that may help. THANKS, uncleray
