Newbie here with a 2007 Monte Carlo SS. Looking to change stock wheels/tires. Stock wheels are 18" x 7", stock tires 235/50/18. I'm looking at 18" x 8" wheels and either 245/45/18 or 255/45/18 tires. I'm partial to the wider 255 tires, but want to make sure that they don't rub against anything. I'm also going to install the ZZP coil overs and lower the car a bit, nothing drastic as they are adjustable but less than 2" drop. Anyone do something like this or have any thoughts? Don't want to get the wrong setup as my first mods. Thanks!!
