About a year ago, on my 2012 Trail, without KDSS, I had the full Toytec Boss lift kit installed, along with the "superflex" rear springs, with the front coilovers set to 2.5 for a nice even stance. I had the lift kit installed first and drove it around town for a week or so with the BFG Rugged Terrain P rated tires. Then I had installed a set of Cooper AT3 275/70/17s, C rated. One thing I can possibly add here is that while the lift kit added significant stiffness to the ride, going from the P rated tires to the C rated also added quite a bit of additional stiffness, and bounce, to the ride too. The coilovers in front and heavier rear springs are probably 75 percent of the new firmer ride and the heavier tires the other 25 percent. I run the Coopers at around 38-40 PSI but you can see that after 5-6k miles the outside edge of the tread is worn a bit. I find this a reasonable compromise between a stiffer ride and tire wear. In the future, since my driving is also 95 percent on road, I think the next tires will be P rated again, whatever I can find that has a pretty aggressive tread.
On the positive side, I don't have the "nose dive" when I brake and I am pretty sure whatever front or rear bumpers or accessories I add it will handle the weight. Also, once I got used to it, it handles really well. Overall, I am glad I went the route I did. I hope this helps.
