Why do I only get 25,000 miles on tires rated at 60,000 miles

Hello -- first, tire mileage "ratings" are really misleading. First, have you rotated your tires religiously every 4,000 - 5,000 miles? Then, have you verified air pressure is spot on almost daily? Most of us don't follow either of those requirements to a tee -- let alone the characteristics that typically cause more tire wear -- driving habits, wheel alignment, and so forth. Honestly, other than rotating, verifying proper wheel alignment and inflation -- you can't do much more, and it is what it is. Different vehicles yield different results with different tires. As far as struts -- what's wrong with them? Did your dealership condemn them? With your dealership, get with the service management if you aren't getting the response you should be.
