A 225/60/15 is the same diameter as Jon's 245/45/17.
Here's the tire size calculator that I used.

That size wheel/tire combo size also depends on the suspension components. On my 69 the front tire is very close to the fender, but in all of my horsing around I have never rubbed. I use H-O Racing front & rear springs, Koni shocks front/ KYB's rear, Offset upper arm shaft, F-X tall spindle and poly graphite bushings. I also use a 1 3/8" front & rear stabilizers. Wheels are 15X7 front with comp T/A 245/60 and rear is 15X8 comp T/A 255/60
Looks wise you might be able to get by using a 17" wheel, but anything more than that you run the risk of making your car look like it belongs in a Hot Wheels box. The cars were never designed for those huge wheels, plus they look like they are on steroids and throw the cars symmetry out of balance.
