2014 Ford Fiesta ST with Axis Touring Cup Wheels 084 by Bryan Redeker BRGT350, on Flickr
P215/40 17 on an ST
For me, the P215/40 17 is the only way to go on the car. Wider and extra sidewall is a win-win in terms of footprint and rim protection. Plus, it looks more like a functional car instead of a tuner with ultra small sidewalls. I found the performance of the RE050A's to be very good, but the Direzza ZII is going to be much better. I ran Yokohama S-Drives for a week and did not notice too much of a performance degradation on the street. I expect track and autocross results to really show the RE050A's being better than the Yokes.
Joe, awesome pick for wheels and tires!
