I was looking into getting the Nitto NTRD1 tires. The problem is that they only come in one size. Would 255- 45 r18 fit the oem wheels.. without any problems?

 

Look at the 1st 3 numbers, The larger the 2nd and 3rd number is the taller the side wall will be IE; Stock is 225/45R18. So 255 would be kinda tall right?
Don't know if you'r car is droped or not. Also depends on how low you want to go in the end with this kind of tire. What do you want to do?
