Front rims too wide?

[boygenius]

I have a set of turbo twists for my 69' beetle. I couldn't help thinking if 18" x 10" rims look good on the rear, why not the front? I currently have 18" x 7.5" for the front. Would it be worth buying a set of rear rims for the front. I am already planning on running 3" wider fenders in the front. Is it safe, harder to steer, Or just not a good idea. I do a lot of dumb things in my car and having the most rubber in contact with the road seems to make sense to me. Thanks for the help.
