My Mustang, which I have had for less than two months, is the first car I have had which needed performance tires. When I got the car, it had (and still has) Dayton Daytona ZR tires. I know these tires aren't great and were probably put on by the previous owner as a 'trade-in' tire. However, they still have plenty of tread (look almost brand new, in fact). I don't drag race, and if I do decide to go to the track it will be more out of curiosity to see what I and the car can do rather than for competition. I have driven in the rain several times at Interstate speeds and have only had one instance of loss of traction. That was the first time I drove it in the rain and was due to a combo of rain, bad pavement and me not knowing what to expect. My question is: for a daily driver and possible 'curiosity run' at a drag strip, will these tires be okay to run until I need new tires, or is the quality of them so low as to make them dangerous? The approach of Winter isn't that big a concern to me as we rarely have significant snow around here anymore. We do have occasional icing, but I don't imagine any tire is going to find much grip on ice.
