Check out tire rack,they have sumitomo htr 100's.205/60 15 for $46.They are summer only tires but have a nice tread design thats exellent for every day and autocrossing.
I have a 2000 contour se sport V6 that i ran in autocross and all season tires just can't hang and it tears them up.I wan't to stay stock.The 205/55 15 will have a major effect om your speedo and also cause your mileage to increase faster because it has a shorter sidewall.
check out the sumitomo's.They have a good price and have a (AA)traction rating.
