please see my post DONT DO WHAT I DID...
in my personal experience after doing this and putting on 2 other branded/tread type up front , I had the shudder issues on inclines and 1500rpm and even when slowing in traffic at slower revs

When i change all 4 to set of new identical tires (not i roll 235/65 r17 on all sdeis). I was ok again shudder gone.
