I'm about to buy a set of new wheels and tires but thinking about size and best appearance for my '70 fastback. I have 225-70-15 now, but am considering 225-60-15, and some folks think 225-60-14 looks better. Might 225-70-14 look to bulky? Also to consider is RWL or redlines with Firestone wide Ovals or Goodyears. I'm wondering about what folks think about the tire size, not the wheel styles, although yes it all goes together to make the right look. A big investment so I have one shot at it since return shipping gets expensive fast!
