Hey Gary,
I just saw your posts. You are correct, the 265/15/16 are the next size down. They are just as good as any 285 tire. The only difference is they are about 1" shorter and a little narrower. I know a lot of members have this size tire and are happy with it.
I also checked out the tires you posted. I like the Toyo's, Bridgestone Dueler 693, and the Nitto Terras. You can't go wrong with the Toyo's and if you like theyt definitely get them. The tread looks like it will be good for on road as well as off.
When I did the lift I was able to use the stock parts and just needed an alignment but I guess it depends on how they are. I know some people have had them replaced. Just go somewhere where you think they are honest and won't make you get them to to make money.
