Stock SR5 4x4, has very little perceivable rake, I had this tire planned a ways before I got the truck, I’m surprised as popular as it was on the much narrower gen3 I’m the first I’ve seen to do this size on a gen4.
I have an SR5 4x4 also and even though it doesn’t have the cross brace it has 2 hard brackets that take the two forward most bolts. I haven’t put a new plate on it yet but I noticed this when I had it on a lift taking the valance and steps off.
