hi picked up a set of 2000 16" 4x4 stock wheels w/ some nice 265"s on them. my truck is a 97 xlt 2wd , just out in the garage and started mounting but looking at the back of the 4x4 wheel and there is a raised ridge directly around the hub bore and another matching raised ridge at the outermost contact point also , my stock 2wd rims that are coming off the truck are totally flat on the mounting surface area , the new wheels mount up just fine but i'm concerned that basically the contact points to the rotor are the 2 raised ridges vs having the whole hub area seated against the mounting surface on the rotor and drum. i know ranger wheels are lug centric so not concerned that the hub bores are a little bigger but the way there seating has me wondering , a yea or nay on this would be greatly appreciated , thanks all
