used a Hyundai Tuscon with front-wheel drive for a single season of service. This is an R16 215/65 sizing. It's obvious that rubber isn't meant for the track; it's loud (or, more accurately, tiring to drive), it's unstable at speeds above 100 miles per hour (at least in my car), and it doesn't fare well in ruts. The good news is that it rows smoothly in all conditions and is virtually silent on dirty streets. Those who spend most of their time on dirtier roads and only a little time on the highway have my recommendation. You should absolutely switch to track rubber.
