These had lots of tread (8000 miles) but were old. This is NOT the vibration you want to feel on the highway. I had the good fortune to be a mile from home and it did not fully separate until I parked.

This had me wonder and check: The R888 are DOT approved but have severe street limitations. That said, none of these apply for Sunday driving in CA.

I just had to replace the tires on my Suburban, same thing, looked fine, lots of tread left, but one started separating with a mean vibration. I bought the tire in Jan of 2015, and figured if one went bad it wouldn't be long till another and another so I told the just replace all.
1st is what was replaced,

For me, tires over 5 years old are trashed. Even if they don’t fall apart they typically ride and handle like crap.

I'm not sure why this is so difficult. There are literally 5 other tire models available at Tire Rack in the sizing in which you're interested: Pirelli P Zero Rosso, Yokohama A008-P, Yokohama Advan AO52, Pirelli P Zero Trofeo R, & Pirelli Cinturato P7. Some are as racy as the Proxes R888R you don't like (though they're not listed as such), but not all of them are. Admittedly if you're looking for rain/snow/4 season tires, you may be somewhat out of luck.

I drove in the rain about 3 or 4 weeks ago. Decent real rain conditions (not just a drizzle), at highway speeds, and kept it about 60 mph. No hydroplaning episodes.

Gave up my quest.............
 

I decided to give up on the 245 rears and ordered a set of the General G-Max RS ultra high performance summer tires. I live way down in the deep south so having to deal with ice or snow is not an issue. The old Falken set that is on the car are high performance summer tires and I had no trouble driving them year around. So, as soon as the Tire Rack get them here, the fronts will get a new set of 205/55-16s and the rear a set of 225/50-16s. The wear rating is 360AA which should do nicely. So be it!

From my "mental note to self" file:
You can't patch a 10-ply truck tire. I've not tried a "plug patch". I found instead if you hit a nail, that tire is pretty much done. This is what happens when you try to patch it:

Todays tires.............
 

I have found that if you go more than about 5' on a flat tire these days it will damage/destroy the sidewall! I think about the only tires you could patch these days would be on a bicycle or a yard cart!
