I have Michelin XPS Ribs on my 5er, 5 yrs and about 16,000 miles. Have been run at 65-70 across the Texas panhandle several times in temps up to 108 (by the truck outside temp display). Tires show very little wear and no weather checking. I may add 2-3 pounds of air at the start of a season and they are good the rest of the year.
Have used Michelin on my trucks and wife's cars/SUVs for many years and hundreds of thousands of miles and never a blowout and only a couple of flats. Actually never a true flat, just a low tire I noticed and had repaired before it went flat.
I did add a TPMS this year. Interesting to watch the pressures and temps. Pressures consistently rose 8-10 pounds after a period of highway driving. Temps on shady side barely rose above ambient air temp. Tires on sunny side rose 10-15 degrees above air temp. Comforting to be able to see the pressures/temps at any time to know how the tires are doing.
