I am considering getting a set of drag radials but not sure on which to get I am leaning toward the Nitto's but dont know if i should get 2 to stay on the car which would be a 3153517 on some very heavy chrome cobra R's or get 2 for my stock 17" rims 2454517 to throw on the car when ever i am going to race it or should i get some for my much lighter stock 16" rims 2455016. how are they in the rain and how many miles can i expect to get out of them. and would i notice a big difference in grip between the 3153517's and the 2454517's
