I have a 2007 Nissan Altima 2.5S with Kelly Edge A/S 215/60R16 tires. They have about 13,000 miles on them and recently notice that they slide/skid in wet/rainy weather. In fact, in June this year I tried stopping on a wet street and slip into the car in front of me. Not good. Does anyone know if the problem is with the type of tires, or is it just the Altima.
