What a great post as I have also been recently looking in to replacement tires. I have the OEM Pirelli Scorpion STR A 255/70R18's. They still seem to have quite a bit of tread left after only 25k miles on them however I unfortunately picked up a nail a week ago. The nail wasn't in the tread but was on the side of very outer rib, right where it looks like the rib transitions over to the sidewall (see picture links below). A friend helped me plug it as you will see but it's not pretty and I'm not feeling real good about it being a good long term solution, especially since I do tow a Travel Trailer that weighs in anywhere from 7k to 7.5k. I stopped in to a shop to have it looked at where the nail was and they said it couldn't be patched.

I could pick up just one replacement Pirelli. But with the other 3 tires having 25k miles on them I'm questioning if that would even be an OK option as long as the new one was on the rear. I'm also wondering what opinions are about just replacing two tires for now and putting them on the back? Ideally I would like to replace all 4 but unfortunately $ is pretty tight right now.

Overall I think I have narrowed my choices down to going with the 275/65R18 size since there are many more options with it. And then to go with either the Yoko Geolandar A/T-S (C rated) or the General Grabber HTS (E rated).
