ok i have got a couple of ways i can go with this. i got 2 15" steel rims with some worn out M/T ET street radials. and i have 4 03 cobra stockers. do i get tires for the 15s or the 17s? i am leaning toward the 15s. the size on the 15s is 275 50 15, should i go for the same size or something different. different tire? any suggestions? anyone selling any. i just spent a few bucks on my car already so tires cant be too expensive. i foud some 275/50/15 KDW D/Rs for 135 apeice brand new. thats the best deal i could find.
