So what PSI is it? Ive been driving around with them at 50PSI cold for 3 months.... yes, the ride is harsh but i was expecting it to be harsh because they're 18's. 
38Cold?
50 PSI cold is way too much. I've got 39 PSI cold and it's a little harsh for me.
I suggest you do what I'm about to do: Lower it down to around 35-37 PSI cold. Probably 35-36. you have 225/40-18 right?

try 35-36 PSI cold. let your car sit overnight so you can get your cold pressure.
