Better than drag radials but not as good as running a full on slick or ET Street (same compound but the Pro's have a slightly stiffer sidewall & smaller contact patch), BUT there are some tradeoffs!
1. Bad weather, forget about even trying to drive on them, may as well be on slicks
2. Treadwear is going to be about like running an ET Street, 1500 ~2000 miles IF you're lucky
