Almost at 40K now. Just started work in Menomonee Falls, Wisconsin which is a 60 mile drive one way! They have two new roundabouts on the road I take and it was raining hard today. I gassed it a little entering the first roundabout and almost spun, gassed it to straighten it out and almost went around the other way. I guess it is time to replace the factory tires, 40K is just too much. I have a set of Continental Conti-Trac three of them are new. I will buy another new one and see how long they last.
