I think they are still using 8 on 6.5, but not 100% sure. So since it's 8 bolts, just measure the distance between two bolts that are opposite. If it's 170mm then it's 8 on 170, if it's 165mm then it's 8 on 6.5.
Or go to one of the big tire and wheel websites, enter your vehicle on a wheel search and it will tell you.
