Cooper Discoverer A/T3 megathread?

LT265/75R16 6ply



I recommend and sell a lot of cooper tires through my shop. So when I had the opportunity to sell my stock tires, I went for the AT3

Balancing was a huge pain in my ass, but I got them zero with a smooth ride. When I swap wheels I'll probably just static balance!

 

That blue looks so good. What color officially is it?

 

Blazing Blue Pearl
Paint colors like this are really amplified with a good polish

 

Yep, this is just the stock SR5 suspension. The calculator showed the tire overlay as basically the same, and I haven’t had any issues / rubbing with those or the wheels.

 

Need more photos of these tires on trucks... To help me decide.

 

Not the best angle but here you go. 265/75R16.

 

Cold or road temp?

 

Going to order 265-70-16 AT3 4S today mounted/balanced and out the door w/lifetime rotate and balancing for under $580 I think it was.....

 

My AT3 XLT's in 295/75r16 are arriving tomorrow! Walmart had the best price I could find (4 for $688 shipped)
on black friday. I was a little concerned about ordering tires from Walmart but it turns out they were dropped shipped to me straight from Cooper's warehouse. I'm having them mounted on SCS F5's which are arriving today....much excite!

 

would love to see pics when you get em mounted.

 

Same

 

Will definitely post the set up once mounted.

 

Just got my 285/75/16's installed yesterday. Don't have a lot to say yet other than they are pretty quiet on the highway and they look way better in person. Can't wait to try them out in the snow but impressed so far. One thing that I'm wondering about is they seem really soft and would chunk easily offroad. Anyone taken these offroad on rocks yet? Did they chunk at all?

 

I did about 30 donuts on a gravel lot and my XLT’s still look new

 

So they will hold up is what you are telling me.

 

They've held up perfectly for me so far

 

Why did they not balance well?

 

Now that I think back, I should have just done a static balance, 2 plane was a waste of time and a waste of sticky weights. Lesson learned.

Over the years I've had trouble balancing large truck tires. Sometimes close enough is good enough.

I swapped out my stock wheels, and went straight for a static balance. No vibration.

 

Put some miles on the tires again, snow and ice. Still great on the snow, not so much on the ice. Put about 200 highway miles on yesterday, no balance issues at all.

 

I hear of people doing this all the time I had no idea it really makes that much difference but I do get the positioning of the weights....
