Nope. 205/50/15 is 23" OD and the 195/60/15 is 24.2" OD.

Missed a couple of steps here:

205/50/15 = 23.08" total wheel height = 72.46" circumference
195/60/15 = 24.22 total wheel height = 76.05 circumference

The difference is 3.59" or 4.95%. At 100 kph your speedo will be out by almost 5 kph - that IMO is a pretty substantial difference.

Now ... if you meant 205/50/16 - that's a different story - then it's reasonably close.
