I live in Southern Calf and never have occasion to drive in the snow. In other words I don't drive up into the mountains in the winter time. I did not have occasion to take particular notice of an entry in the owners manual until a long time after I purchased the car new. My Sonata is a 2000 year model and has R205/60/r15 tires. The owners manual states that - "tire chains should not be used on the R205/60/R15 tires" It goes on to say that there is not enough clearance to use chains on them. I wonder how many people have found this out the hard way? Old_Timer
