I think you are spot on about the front tire sizes. I put 225s on 1061 my first set of Avons, as the 245s were not in stock at the time. The following 2 sets have been 245s. (295 rears on all 3 sets.) Parking and slow speed manners are better with the 225s. High speed handling, cornering and general track performance is better with the 245s. Depends on what kind of driving the OP will be doing as to which would be optimal, though either 225 or 245 are better than anything else he could mount in a street legal 15" radial.
