I recently just ordered Kumho Ecsta MX tires from tirerack. These are the sizes i ordered (2) 245/40/18 and (2) 275/40/18. I then got an email stating that the tire sizes are shorter than recommended and that i should be using different sizes. What sizes should i go with? i have 18x9 saleens, and a eibach pro kit drop. What sizes would work best without rub?? thanks

 

common guys i really need help so i can figure out what sizes i am going to reorder for tomorrow!!
