Simply passing along what I was told by Tirerack salesman on the phone.
I was relating to him that my rear Conti wore out 2X as fast as fronts.
Conti has no treadwear warranty
Inquired about several other mfg. of All-Season tires WITH warranty in staggered setup for my next purchase
Was told directly that it didn't matter whether the mfg. offers a treadwear warranty or not - if you are running staggered setup - the warranty is VOID.
Now whether that particular person had any idea about what he was talking about - couldn't tell you. But as a rep of a large company that's main business is selling tires day in & day out, I would think they would be trained to give correct info...
