I put some on my 2004 Ram 1500 this past winter. I drove to Bemidji, MN from KS in a good amount of snow as you can imagine this year. Pro's: Pretty quite on the highway, good traction on very cold, dry and wet pavement. I was pleasantly surprised by extremely good traction on snow and ice. Con's: After driving that 1200 miles I notice 2 things. First, I noticed my speedometer was (and is) registering 3 miles per hour faster than what I'm driving (by gps), so they are a tiny bit smaller than they're marked. (Yes, they are marked as the correct OEM size). Second, I developed a noticeable vibration on that trip. Thinking I lost a wheel weight or something, I took them in to where I bought them upon my return home to have the balance checked. They found the two front tires were out of round. They then checked the other 3 which were fine (I had also bought a new spare to replace my 15 year old original). They replaced the two defective tires and all has been good except the speed discrepancy. I have about 3000 miles on them now. For the price I paid and since it is an older truck I consider somewhat of a "beater", I'm not complaining.
