68 barracuda tire size

hello folks, i am restoring my 68 barracuda.Now i have 215/70/14 on my Rally wheels.Will 235/60/14 or 245/60/14 work or is it too big. I put new leafs on the back and my tires look very small now. Hate to buy the tires and they don't fit.What sizes are you running on your 68?
