It's going to be slightly wider and taller. I think once it's on the car, it will not look out of place. It's literally the same tire I've been running for the last 75,000 miles...just 1/2" taller. For anyone wondering, 185-60-15 is the size tire used on the current Ford Fiesta base model.

If others are interested in doing this & you still value your powertrain warranty, I would suggest hanging on to your factory tires.
I understand people's concerns about deviating from normal tire sizes. If you don't know what you're doing...then don't do it!
I currently run LRR Bridgestone Ecopia tires with lightweight wheels. A 185-60-15 Ecopia has the same contact patch as a 165-65-14 Enasave. My aftermarket tire/wheel combination (with 185-60-15 tires) will actually weigh less than the OEM Mirage 15" alloy wheel with 175-55-15 tire. Ultimately the only real difference is a .7" increase in the tire diameter...or about 50 fewer tire revolutions per mile.
It will be another interesting experiment when I need new tires. The conventional wisdom when I joined the forum was that 15" LRR tires could never equal the efficiency of Enasaves. I think I've successfully busted that myth. I'm ready for another challenge.
