difference b/t these two tires

well i am in the market to get some new tires to rplace the dunflops on my truck. i already have a set of wrangler duratracs mounted up on a second set of wheels for the trails, so im looking for a less aggressive tire that will be quieter and smoother on highway driving, much safer thean the dunflops on wet roads, and wont make me nervous about getting hung up if i go cutting through the yard. reason i dont just run the duratracs at all times is i have a 6 month old and the added roughness to the ride along with the noise from the tires keeps him restless in the truck.

i have it narrowed down b/t two tires.

or
the cooper discoverer A/T3 http://www.discounttiredirect.com/d...c=27122&counter=4&ar=75&rd=16&sw=false&cs=265
both 55,000 mile warranty extremely similar in price and look very similar. what i am looking for is "ideally" someone who has ran both kinds to give a comparison of road manners/noise but i realize that isnt likely to happen so maybe some that have at least one of them and if they would stick with it for my needs or try the other one out?

as always thanks in advance for the help and yes i searched first, but nothing i read answered my questions. only talked about the tread life of coopers in general and offroad performance or snow performance.

 

Check this thread out. 3 or 4 of us that have the AT3s have already posted up with our opinions as well as one person running the ATPs. I've got the AT3s myself and put my comparison between them and the older ATRs in this thread also:

thanks pugga i found the thread about your at3's and a few others but it didnt seem as though any said anything decidingly different about one tire over another. both had very similar reviews from what ive seen........ am i correct in this or did i read them wrong?

 

Sounds about right. I definitely haven't seen anyone who has had both tires and can compare one against the other and there seem to only be a small handful that have the ATP. Generally, both seem to have good reviews. You'll find more reviews, both good and bad, about the AT3 simply because they're a more widely used tire. Wish I could help you but I've never had the ATP or even seen them in person.
