You would want 40 series tires for 18s. Shane has 20's so the 30 series apply. 19's would need 35 series. But this is not true for all setups, alot has to do with the width of the tire so dont use that as a rule of thumb.

Well it all depends on your setup really. Most people do 40 series up front and 35 series rear. Put it this way I have some 18x12.5 -10 coming and I'm going with 265/35 for the rears
