I have a 71 Cutlass and recently purchased four 14 inch Rallye wheels. What dimensions should I seek in a tire? (ex. 245-45-17) White wall or black...

 

I can't tell you what might or might not fit on your car as I don't have a Cutlass. But I am running 275/40-18's on my Custom Cruiser. I used this cool siteto research what sizes I wanted and how they compared to other sizes. Works really well.
