Stock is 275 60 20.
1. Is the extra inch worth the $400 or so.
2. On every spec chart the Tread(11.3)width is just .4 of an inch narrower than the section width(11.7). Thats a lot of tread. Is this accurate?
I have the OEM size Michelins and love them, wear forever.
99% interstate and bought one set, 70K miles ago. Just now hit 6/32'nds on one tire, 8/32'nds on another. 11 replaced under road hazard, 40K miles ago are at 10/32'nds.
I did replace, on my own, due to peeling out, about 20K miles ago, it now has just under 12/32'nds so no real wear, at all.
