Too many of you are blanket stating ST have 65mph limits.
One, they do not have limits, they have ratings. If you think that over 65mph, they suddenly fail, you're understanding of ratings is skewed by the internet.
Two, there are MANY ST tires that are rated for 75-87mph.
As far as what speed to travel, its a personal preference and you'll naturally find a comfortable speed for your driving style and rig itself. Of course, high speed naturally add risk but that threshold is not the same for everyone in every condition.
