Need to buy tires front barracuda 1968 - w/ disc brakes conversion

I have an SSBC disc brake conversion on my 69 cuda. It had 14 x 5.5 rally wheels with 215 70 14 on the front when I got it. I bought 15 x 6 cragars 3 3/8 back space, I think. I am running 195 60 15 on the front now. Wish I would have went one size larger.
