Question about tire size for 14"X 7" Mopar Rallye Wheels

The reason is probably because those biased ply polyglas tires are more square on the outside edge of the tread. It gives a fuller look. I agree with you. I hate the rounded edges of the radial tires and the BFGoodrich tires have some of the most rounded edges out there.....that is IF that's what you're referring to. the old "Goodyear Eagle ST" tires were very similar in appearance to the squared off biased plys. They looked good and you can still find them NOS in some places.
