Welcome to the group Cardone. The 195/70s you mention appear to be very popular here and there are several manufacturers who supply white walls. They are slightly beefier than the originals. There are other opinions however.
I suggest you read the section in the technical manual on tires (third heading from the left at the top of the page) and also do a search on this forum by clicking on the fourth heading from the left at the top of the page and typing in "tires". You will find a world of good discussion there.
Again, welcome to the group and let the Forum know what you purchase. Pictures are always appreciated!
