Dont' have too many pics, but I can take some if you like. The 235s are skinny. The ST Maxx is the widest 235, however. I've seen pics of 235 BFG ATs on the Frontier and I think those are too skinny for my taste.
The tires are load range E so they are definitely not as compliant as the stock tires. You will feel more bumps on the road for sure, but for me it's not really that bad and something that I got used to pretty quickly. The truck is my daily driver.
I had some coil bucket contact with the upper control arm when I first installed the 2.5" spacers. I put on bump stops on the the UCA and that solved the metal-on-metal clanking for me. I also recently replaced the stock front shocks with some Bilstein 5100s and that improved the ride noticeably. Bumps are no longer as jarring as before. I should also mention that I removed my anti-roll bar. Truck leans a little more in turns but with my conservative driving habits not an issue for me. Smoother suspension off road makes it worth it to me.
