Gmw, thanks for that tire option! They look great and I'm calling my tire guy in the morning. The 195/70-15 is actually a half inch smaller in Dia vs my current 14" tire so clearance is a non issue.
The 225/70 size is 1.3" larger in Dia so I'd lose almost 3" of space between tires. I think 2" is cutting it close!
You have to realize that if a tire is 1.5 inches taller than yours then you are only loosing 1.5 inches between 2 tires because you would divide the overall increase by 2 to see how much you would lose on each side. Or on top for clearance you would only lose 3/4". So basically you would lose 3/4" all around each tire which equals to 1.5" of diameter increase.
