Tire wear

[ccapehartusarmyINF.(ret)]

it looks like you have positive camber \ / wich would account for the sloppy steering
by the looks of the left picture
holy crap youve had those tires since 2010 here in arizona you go through a set of tires about once every year or 2

Those look like soft compound snow tires (lots of zig-zag siping). If so, regular use on dry pavement will do that to snow tires.What type Michelins are they? If I had to guess I'd say Michelin LTX Winter snow tires (http://www.michelinman.com/US/en/tires/products/ltx-winter.html)

Snow tires + Arizona heat + dry pavement driving = Bad news.

The tires are Michelin LTX MTX. What would be a good tire for purchase here in Arizona. Something a little aggressive for in case we get orders somewhere cold but good quality for hot Arizona weather?
