Hi,
We have lived here(Central Oregon) for almost 30 years and have tried a lot of different tires and brands, what we found works the best on cars and trucks alike are a good m/s tire that we have siped. The siping of the new tires makes them grip better (we think) than studs in more types of driving and helps make the tires last a lot longer. The studs are not always the best for traction, especially on wet roads. Another perk of siping is that you dont have to fight the lineups at the tire shops to have them put on or taken off, they can run all year and save time and dollars that way too! We have ran large lug tires on the trucks and some mild tread on the cars and have found a real treasure in the siping. The cost is cheap per tire too.($8-15) Ask your local tire dealer about it, they will tell you a pros opinion!
