I'm on my third set of Coopers AT3... I agree with the above grading. Very important (with any tire) with this tread pattern is rotation and inflation schedules. If one takes the camper off you have to redo an alignment or the tires wear badly.... not their fault!

Say... help me decide what I may need to do. I ordered a set of Cooper Discoverer AT 3 LTs for my 2019 Toyota Tundra that's carrying a Grandby.  Should I have ordered Cooper Discoverer AT 3 XLT? They seem more substantial the the LT's. Will be doing some off road driving but nothing extreme. XLT is a E rated tire, While I believe the LT is a D rated tire. Thanks for your input and suggestions.

I have the Cooper Discoverer AT3 LT tires on my 2010 Tundra with Hawk. They are E series tires.  Found this link that discusses the differences between the LT and XLT.

 

Really like my LT's. The increased tire mileage would probably be a good thing of the price difference isn't too great.

My LTs are E rated. I don't recall my reasoning right now but I looked at the XLTs and decided the LTs were better for me.

Thanks for the comments.... I did error in rating the LT's. That being said it nice to hear folks take on these tires. If you have a comment or suggestion please continue sharing.

I went with the XLTs last fall and am very happy. Paid less than $1000 at Big-O. They are quiet on the freeway, have great traction on Forest Service roads, great in snow/wet surfaces. Really don’t think I could have gotten a better tire for my rig and I researched them all. I like the look of the more aggressive tread...good luck in your search, my feedback is the XLTs are great.

I have been looking at these tires myself. The way I saw it was the tire pressure range. The LT was 50-81 psi where the XLT was 35-81 so to me that meant it would be better in an air down situation. Am I looking at that correctly?

When I ran Coopers I found them to wear fast and unevenly.  Same truck with same pressures had no issues with Pirelli or BFG tires.  Not a Cooper fan.

My truck rode well with BFGs but they wore quickly. Its interesting how different vehicles respond differently to different tires.
