The only good Vredestein tire is the cheap Ricorso. The others cost too much and don't last. I wouldn't worry too much about running 140 PSI. Stick with 100-110 and you will have a more comfortable ride.
The 25C gatorksin by continental is a much better riding tire for comfort and supple road feel. I think the Vredesteins are no different than the cheapest multi colored tires on the market. They have lots of advertising hype.
