Ok i have the bf goodrich kdw ' 2s looking to get some drags i have 255/45/18 all the way around which size will look right they only offer the drags in 265/40/18 , 275/35/18 , 295/35/18 , 315/30/18 anyone know which will keep the same height as the 255/45 and not make my car look like a 4wd in the rear and if u have this set up pictures would be gr8 thanks [8D]

 

The 265/40s are 0.35" shorter
The 275/35s are 0.73" shorter
The 295/35s are 0.46" shorter
The 315/30s are 0.80" shorter

So the 265s would be closest to the height of your front tires.

 

Get drags from another vendor that sells on your size and almost every tire website there is a tire size calculator that you can imput ur original size and it will tell you the difference.
