Shortly after I got my37 Dodge together I’d mentioned to a friend that I was going with something just a tiny bit shorter and wider on the back. He asked me what size I was changing to and I told him it would be the same size just a different brand and tread.

He didn’t believe me that there was a size difference so I took a couple of pictures. Both tires are mounted on the same rim and have identical tire pressure. even though both tires are 235-70R-15s the new tire is about 1/2" shorter and has about a 3/4” wider contact patch.
