are you sure itd be THAT bad? im sure its different with the auto and all but i have 456s with a 26 tall tire on my car and i can go faster then 65 while being below 3500rpm
id personally go with whatever your car is going to perform the best with for 1/4mile, thats what i did and i dont regret it one bit
however the next set of tires i buy with be 28 tall so when im driving around town it'll be similar gearing as to when i had 410s
