In the Camry 17" wheel size the H version has 11/32" for starting tread depth. The V version has 9.5/32". Interestingly Michelin provides a 100,000 km tread wear warranty for both versions regardless of starting tread depth. Consumer Reports however gives an excellent for tread wear to the 11/32" version and a very good for the 9.5/32" one.Had them on my Saab 9-5 and put over 40k on them. When I sold it they were still going strong with at least 20k to go. Those were H rated though, may have been a harder compound. If I don't get 50k out of these I'll be pissed, after removing a perfectly good set of Bridgestones.
In miles these ones I have look to be heading for a 25,000 mile life. The Michelin Pilot Exalto A/S on my Mazda 3 looking like they are going to make 43,000 miles. Consumer Reports only rates them as good.
Something seems fishy about how long these Primacy tires are lasting... Perhaps I blew it by running them at 38 psi. The Pilot Exaltos are run at 32 psi.
