I just posted yesterday about my Cooper Discoverer ATP tires on my 2012 FX4. If you didn't see the post then do a search for my username and you can check out the pictures. The ATP is a bit more aggressive than the AT/3.

I hope you have gotten these mounted up and bolted on your truck by now. I was curious if you were even close to having any rubbing issues. I have an 09 FX4 with 20 wheels and stock height and was thinking about getting these tires in that size. But I wanted to make sure I won't have any clearance issues first. Thanks.

I have the A/T3s on my FX4 275/55/20. Absolutely love them. They're great in the snow, and well mannered on the road. Just had my first rotation at 6500 miles and the guys at discount tire said they still look brand new. Here are some pics.

Just put 275/60/20 zeon ltc on my truck absolutely fantastic tire on dry pavement and throughout the couple of inches of rain I drove through the weekend they were mounted

It appears that Cooper only makes the AT3's in 275/65 for 20 inch wheels. I am not for sure how you guys are getting other sizes. Anydangway, does anybody have any rubbing problems with 275/65/20 with stock height trucks?

If you go on Cooper's website and under the "tires" drop down menu go to "sport utility." Then click on "tire details" for the A/T3 then "sizes and specs". 275/55R20 should be the last size listed. Discount tire should be able to order them for you. Good luck!

I have the AT/3 275/65/20 on my truck and love them. A little stiffer than stock because they are an LT tire but not by much and the ride is awesome.

I had them on a week before I put the 1 1/2 inch level on the truck. No rubbing problems in that time. Though now I do have the traction control issue on very tight uphill turns...

You can see pictures of them on the truck before the level in my garage.

I just got the Discoverer AT3's mounted three months ago. Great tire. Have put on over 3500 miles and I see no wear. If they continue to hold up as they are, my next set of tires will be Coppers.
