What size tires can i fit on my Fx4 2017 F150 with a 4 inch lift?
 

I have a 2017 Fx4 F150 that I am getting a 4 inch fabtech lift put on. I also bought 18x9 +1MM offset Fuel Battle Axe Rims. The tires I bought (with the assistance of the person at Discount Tire) are 325/65R18 Falken Wildpeak A/T. The person at discount said these tires should fit but I may have to do a little trimming but nothing major. My question is, do you guys think these tires will fit or will they be too big? I have searched around and can't seem to be able to find an answer. Thanks for the input, the tires have not been ordered yet because he said they can't order till tomorrow. So if the tires will be too big I still have time to tell him to not order the tires and to order a smaller size. Thanks for the input.
