steering vibration

Had my winetr tires installed a couple of months ago.. don't drive the truck much. Well today was the first day since the tire change that I drove past 90 km and let me tell you the steering vibration was something else I had to slow down or felt like the front tires were going to come off. It's -22 this morning thinking that any possible snow/ice would of been stuck but everything looks clear. On another note a couple of days ago my clock display came on and since then no time on the clock. Just find it strange to loose the time?

any feed back would be greatly appreciated.
