Yea, they make a 235/55 17. On discount tire, they list 37 options for that size. It does let you put in tire sizes that you can't even purchase, but it obviously is a tool that requires the user to know what size tire they can even purchase. I thought it was fun to play around with it even though I ended up purchasing a set of 15x6 rallys for my Cat.
I thought I learned something form it.

Any suggestings on tire size for my 65 cat with 15x6 rallys. It appears that these wheels have 3 7/8 backspacing on them. from what I could tell, a 225/70 may be as big as i can get in the rear. Thoughts?
