i am looking for rear tires to go on my daily driver (in the signature) that will perform pretty well on the street and track. ive pretty much narrowed it down to these 2 tires. i will putting them on 15x10 wheels, and the sizes id get would be 275/60 for the nittos or 345/50 for mickey thompsons. how would these tires compare as far as performance at the track, miles i could get out of them, street driving, driving in the rain? could either of these tires be driven in the snow? i could get the nittos for $282 at discounttiredirect.com or the mickey thompson sportsman I's at summit for approximately $335. if you guys know where i could get either tire for cheaper, please let me know. ive read a lot about the nittos, but i dont know much about the mickey thompson sportsman I's, so if you know anything about them, please post it. keep in mind the size difference when youre talking about how theyd compare on the drag strip....nitto didnt have any wider sizes . thanks in advance
