Appropriate Tire Size

I just bought set of rim and tire for 1973 Scamp. Rim has backspacing of 3.5"
with 225/60R15 tire mounted. I installed them. Rear tire is great but front would touch fender when making sharp turn. What is the appropriate tire size for front?
I'm thinking of
195/50R15
195/55R15
195/60R15
205/50R15
205/55R15
205/60R15

Thanks,
Scamp:violent1:
