Can anyone tell me if a 19x10 rim will fit on a tC and what size of tire would be best? I'm putting on a fat body kit and I am needing WIDE rims to come out even with the body kit!

 

You would need a tire that's at least 255mm wide (10"=~254mm) so you don't stretch the tires, but you have to make sure the offset of the wheel itself isn't going to cause problems. 10" seems a little wide, so you might have a hard time turning if you aren't careful. I'm not sure about the other measurement, maybe a 30? 255/30/19? You might want to look at other options too.
