It rained last night and I went out this morning and it was around 41 degrees and I went to turn a corner and my front end slipped. I figure it is the cheap a** continental tires on the car so I was looking on consumerreports.com for some all-season good tires and i dont know what type of tire the altima requires... I figure since it is getting colder and colorado has a lot of ice that it may be a good idea to find a set of new shoes that work on rain and ice - not really worried about snow. Do we use normal all-season tires, no speed rating, S (112mpg), T (118mpg)) class tires or Performance all-season tires H (130mpg), V(149mpg) class tires? I am figuring that we use the normal all-performance S type class tires because our cars are limited in how fast they can go - so does anyone know what nissan recommends off hand? I dont have access to my manual at the moment.
