Can Someone Please Help Me??????

ok, ive been wanting to raise my grand cherokee and add bigger tires. i found a site where this guy had it exactly how i wanted it. the problem is that it doesnt say how big the tires are and how tall the lift. i really want to know at least how big the tires are so i can figure out much of a lift i need.

If anyone here can some how figure out how big they are by looking at the pics i would really appreciate it. heres the link: http://www.cardomain.com/memberpage/393227
