Hello. I have a tire size question, we have two Chevy Cobalt's in the household. My wife has a 4 door 2008 LT with 205-55-16 snow tires. I have a 2009 LS that I upgraded to 205-55-16 all season tires. I have a set of 195-60-15 on steel rims from my car that I wanted to put on the 2008 LT but that car came from the factory with the 16in tires. Is it safe to downsize the LT to the 15in tires? I don't see any major suspension difference. not sure what the LT upgrade includes. I really do not want to buy 4 new 16in tires if these 15in ones will work, but the car needs to be safe.
