Michelin has stopped producing the Latitude in several sizes, 285-45-19 for one (rear tires on 4.4s with staggered 19"s). Found this out after installing a set of 255-50-19" OE BMW Latitude Tour HP ZP take-offs with under 100 miles on them. Would not have bought/installed the Latitudes had I known the rear size is discontinued.
Thought I would post the best deal currently on Ultimate High Performance (UHP) Summer tires (fall is the ideal time to by "summer only" tires, manufacturers know everyone is looking at all-season and snow tires).
Found Group-A Tire, Lindhurst, NY, is selling Vredestein Ultrac Vorti and direct shipping from the primary Vredestein US hub (this is located in NJ, the tires are produced in Holland and shipped to this location). I'm OCD about FRESH rubber (even street tires grip better/wear longer when heat cycled shortly after manufacturing).
For those who have never heard of Vredestein, the company is over 100 yrs old, privately owned (Apollo Vredestein, decendant of founder), colaborates with ItalDesign/Giugiaro Design, Hamann (installs these on their high output modified ///M5s and ///M6s), Lorinser (installs these on high output Benzes....Benzi???

)
The Ultrac Vorti carries an XL load rating and perform best on heavy vehicles. Low void contact surface (put these on a light car, hit standing water while going fast, you WILL hydroplane!).
The set listed below is rated for a max load of 8600 lbs., Y speed rated (+186 mph).
300 tread wear rating (higher wear comes with having "no excuses, ultimate grip" summer rubber.)
Group-A Tire will honor their e-bay price (no tax/free shipping).
255-50-19 is $249
285-45-19 is $276
$1050 for a full set. Killer price for killer summer tires.
I called EVERY US Vredestein dealer I could find online, asked if they did price beating, was asked how much I saw them for, when I told them they said NO WAY!!! Other dealers can't believe that price for these tires.
