I have 2 195/65r15 on the front of my 2004 Chevy Cavalier and 2 195/60r15 on the back.
I have 4 p185/65r15 that I can have put on. Will this work?
195/65R15's are the correct tire for your car. I never like mixing tires sizes like you are doing now. 185's will fit, as they are smaller in diameter by a 1/2".
What is the manufacturer's recommended size? Using a tire that is a different diameter than specified will likely cause your speedometer to read incorrectly.
