Hi, I did a search and didn't see this discussion. I have a 92 LT1 Coupe. I bought it with 106K and just a few thousand mi on the current set, BF Goodrich g-Force T/A KDWS 275/40-17 ZR rated. I now have 135K mi and it looks like I'll need rubber next year. I rotated them once. So I guess I'lll get about 40K on them. They have worn real evenly. I rarely turn off the ASR and burn them ! Any experiences and/or advice ?? Here's what Tire Rack has as I want all season: http://www.tirerack.com/tires/CompareTires.jsp?sortValue=1&filterType=all&displayResults=10&compare=true&autoMake=Chevrolet&autoModel=Corvette&autoYear=1992&autoModClar=&vehicleSearch=true&compareList=0%2C1%2C2%2C3%2C4%2C5%2C6%2C7%2C8%2C9&RunFlat=All&goWhere=%252Ftires%252FCompare1.jsp&minLoad=S&loadRank=2&minSpeedRating=V&sortCode=50750&width=275%2F&ratio=40&diameter=17&speed_rating=V&speed_rating=Z&speed_rating=W&speed_rating=Y&speed_rating=%28Y%29&performance=UHPAS&startIndex=0 Thanks, Vern
