Any long term reviews on Cooper Discoverer At3 4s?

Yes, it must have a magic compound that stays pliable at 45 F and under and can be driven year round. Was someone mentioning they wear out at 30,000 miles?
Who ya gonna call when selecting winter truck tires. How about Canadian Tire, the largest tire retailer in snowy CANADA. The Cooper AT3 4S did very well in their “independent” testing. 
Hope that helps.

AT3 4S on my Touareg for 10,000 miles and they're wearing like iron.
Here is my “pin test” to check the depth of the sipes. They go the full depth of tie rubber thread. These are on AT/W winter tires. Enjoy.
Dad just stopped by the house after he went to the tire shop this morning. He did in fact get the AT3 4S tires on his truck so if I remember I will give an update after some miles. He took advantage of two mail in rebates and 6 months 0% on the Cooper card. Right at $700 after the rebates with mounting and taxes.

Have the non 4S version on my grandfather's 14' Grand Cherokee. I think about 18k miles on them and I think the tread is about 1/2 way to replacement time. We use them in the desert in harsh rocky conditions they're kind of chunking in the tread and sidewall, but not too bad. My only complaint is they're really noisy as they've aged.
This is what I get out of most of my tires. I can't even imagine getting 65000 miles from a set of tires.
How many more seasons you figure you got left on those? And how's the winter performance with that little tread left?
Th
The wear bar for this winter tire is at 8/32”. The tread is presently at 12/32”, so for sure I’ll go for this winter and see how it looks in the spring. I’d like to hear at what depth others buy new winter tires.

Even down south I’m going Cooper … SRX will go on the Tahoe soon - and a fellow Jeeper took my advice on the ST Maxx … Loves them ~ and that’s likely in the Rubicon’s future (no hurry there)Who ya gonna call when selecting winter truck tires.

Thanks! I'm just curious how low is it ok to run these because I have the AT/W's as well and I'm finding the winter performance to slowly degrade even though the tread hasn't worn much. Might be due to the compound hardening over time. I do see that the sipes are starting to wear out on yours.
The sipes are weird on mine. Some go the full depth as checked with a stick pin, and some have disappeared.
Do you realize the 4S stands for 4 season ? Cooper says they are for year round use,
Yes, have a look at my response to Reddy45 regarding the same question.
I still don't understand why you say they're meant to be taken off in the spring and installed in the fall.
They're an all weather tire that excels in the snow. Not a snow tire that people mistakenly use all year.
Winter tire, according to the winter tire test attached. In fact they were number 1. They have a mountain snowflake emblem. Cooper can call them what they want but the OP mentioned there are complaints they wear out at 30,000 miles. That’s what you get when you drive a winter tire year round.

Ok, I live in the very Northern part of Jersey and do have all 4 seasons. A bit more than 20000 miles, rotate every 6000 miles and run at 40 psi. Based on the current wear, 50000 miles plus will easily doable.
