If the current tire is a Bridgestone Drive Guard RF, try it, and you will probably like it. My first ct was a Dunlop Winter Sport, and it required lots of work (pushing and pulling) in the twisties, but lasted over 22,000 miles. I did not know it sucked, because I had nothing to compare it to. I next tried a Pirelli Snow Control and loved it, with its rounded edges, it laid over like a mt in the twisties, but only lasted 10,000 miles. I currently run a Bridgestone DG, with around 13,000 miles, and looks like it will easily last 20,000.
With the Bridgestone DG, I was initially leery because it had a profile and squared edges just like the Dunlop WS. But on the road, the difference is like night and day. It handles nearly as good as the Pirelli in the twisties, and is smooth as silk on the road. That's why I suggest you try yours first, before condemning it. I cannot explain why the squared edges work so well on the DG, yet sucked on the Dunlop, but my next tire will probably be another DG.
