Vehicle Fitment: .So You need a 15inch one for P225/65R17 When A<180,choose according to diameter or smaller one ,both would be good.For example, your tire is ST175/80D13,A=175,diameter 61.02cm,you could choose 14 inch one as it has an elastic cord,but 13 inch cover would also fit as the tire is too narrow If the tire is too wide(A>280) ,choose 18inch one.For example diameter of 295/45R18 is 72.27cm,you could not use 15inch cover by diameter fitment becuase it's too wide,if you need a tightly fit cover ,pls choose 17inch one.Or you could simply choose 18 inch one,you won't risk to choose 18 inch large cover when the tire is too wide as it has an elastic cord.3.If you do not know which one to buy and do not mind loose fit,just choose 18 inch one as it has an elastic cord,it won't be a problem when it's too large.But if the cover is too small ,you could not use.
