Firestone Destination M/T or Cooper Discoverer STT?

I'm looking to put a new set of mud tires on my truck (2008 TRD Sport), and I've narrowed it down to two options: Cooper Discoverer STT M/T and Firestone Destination M/T.

I understand that either of these will be more than capable in a muddy environment, which is all I get to deal with when going offroad down here in Louisiana. What I'd really like to know is which of these performs better on wet pavement?

We get a lot of rain down here all year long, so whichever of these has better wet pavement traction is what I'd like to buy.

If anybody has any additional insight on Cooper vs. Firestone (warranty, tread wear, or otherwise), please feel free to offer it up. I'm looking for any reason to sway me one way or the other.

Would I have any problems putting 265/70/17s on this truck? Everything is stock. The Dunlops are 265/65/17, but I'm not sure what the largest size is that I can go to.

Thanks!

 

Bump?

 

I believe the Firestone is rated better overall, but if it were me Id buy the coopers. The coopers seem to have more siping which is good for the wet pavement. It seems the Firestones are really apt to chunking- some entire lugs can get ripped off the carcass! I was interested in the Firestones until I heard about that issue and researched them a little more. Just ask silverback07, he's got proof!

Here's what happened to his.... Note the missing lugs!
